PRODUCTION DEPARTMENT
CAR BODY SHOP- Each metro car consist of six modules.
 Under frame
 Side wall LH
 Side wall RH
 End wall
 Cab
 Roof
Each of the above mentioned components start their journey from stainless steel
parts that are sub-contracted to other companies. The side wall and the roof are
fabricated in the car body shop.
According to the drawings both the side wall and roof are fabricated using
robotic spot welding machines. The weld points are also specified in the
drawing. The fixtures are welded using TIG (tungsten inert gas welding).
18 | P a g e
LAY OUT OF METAL FABRICATION SHOP
All the extra fittings are welded
using TIG welding to either the
roof top or the mid and end
sections.
Basic structure of roof top is
made.It is then spot welded to the
panel.
End panels are fabricated,spot
welded and levelling operation is
done.Mid section also fabricated
here.spot welding is used.locators
and clamps are used to arrest the
motion of the parts.
DLD panels of mild steel are
attached by spot welding in which
workbase acts as a second
electrode.hence the machine has
only one electrode.
19 | P a g e
LAY OUT OF CAR BODY SHOP
Spot welding of roof sheets
Serves as one of the input to the section Assembly of the entire car body

The side frames shown
below are integrated to
form the side wall.
Welding used is MIG
welding.
All the fabrications of
the roof made are
assembled here using
MIG welding.
Hardening of the shell is
carried out. Electrochemical
grinding is performed to
remove stains of spot weld.
The assembled body is
washed.
20 | P a g e
UNDER FRAME SECTION
This section forms an integral part of the overall assembly as it has to support the
weight of the car. This section manufactures underframes for Indian railways, sub-
urban trains and metro. For the metro stainless steel is used which is in contrary to
the mild steel used for Indian railways and the sub urban trains. Basic process that
are involved are MIG, spot and seam welding.
SEAM WELDING
The three sheets are placed on a jig with the seam welding machine running along
the side of the jig. The X in the figure indicate the initial tact weld. Once this is
done a complete weld as indicated by the line is done.
21 | P a g e
The seam welding machine consist of a roller which has high electrical
resistance.it also has a supply of cooling water which helps in solidifying the
weld immediately.
Principle-when the power supply is switched on due to the high resistance of
the roller wheel, heat is generated. When this roller is touched to the SS sheets
they melt and solidify joining the two sheets.
22 | P a g e
The underframe consists of two end blocks and a mid-block. All these are made
from basic components and welded either using spot or MIG welding’s as per
drawings. The body bolster and the center sill are made of mild steel and
separately made before welding to the underframe.
KEYSTONE WELDING MACHINE-the weld points are initially fed to the
machine. The machine stores them as (x,y,z) co-ordinates. For each program of
welds there are 34 points (17 done by each robot).there is a pneumatically
activated holding device which keeps the surface of the sheet on the datum. The
operator uses the joystick to move the robots. The robots have their own NC
codes which the computer processes.

END UNDER FRAME
The end under frame consists of the following components
1. Body bolster.
2. Center sill.
3. Rear assembly of center sill.
4. Support beams.
5. Anti-climbers.
Shown below is under frame with the end under section visible. The metro trains
use a similar end under frame.
25 | P a g e
The sub-assemblies of the body bolster and center sill are welded using MIG
welding. Initially tact weld is performed then continuous weld is done. The
attaching surface of the body bolster is machined by a face mill in the machining
section.
All the components are then welded using MIG welding. Vertical welding is also
performed by using a jig that can rotate 360 degrees.
After vertical welding the given assembly is turned 180 degrees and welding on the
underside is done. Then the end under frame is grinded and buffed. After this tests
are conducted in order to check for any defects present. This is then inspected by
the customer who gives the clearance to proceed to the underframe shop.

PIPING AND BRAKING
The air braking system is used in the metro car.it is an electro-pneumatic
controlled system. The main compressor unit is located in the trailer car. Power
required to run the main compressor is taped from the electrical grid using the
pantograph. There is also an auxiliary compressor unit for lifting and dropping of
the pantograph. The voltage required for the compressor is stepped down using a
step down transformer.
The metro train system comes equipped with three brakes
1. Service brake
2. Emergency brake
3. Parking brake.
31 | P a g e
The main parts of the braking system are
COMPRESSOR
The pump which draws air from atmosphere and compresses it for use on the
train. Its principal use is for the air brake system, although compressed air has a
number of other uses on trains.
MAIN RESEVOIR
Storage tank for compressed air for braking and other pneumatic systems.
DRIVERS BRAKE VALVE
The means by which the driver controls the brake. The brake valve will have (at
least) the following positions: "Release", "Running", "Lap" and "Application" and
"Emergency". There may also be a "Shut Down" position, which locks the valve
out of use.
The "Release" position connects the main reservoir to the brake pipe. This raises
the air pressure in the brake pipe as quickly as possible to get a rapid release after
the driver gets the signal to start the train.
In the "Running" position, the feed valve is selected. This allows a slow feed to be
maintained into the brake pipe to counteract any small leaks or losses in the brake
pipe, connections and hoses.
"Lap" is used to shut off the connection between the main reservoir and the brake
pipe and to close off the connection to atmosphere after a brake application has been
made. It can only be used to provide a partial application. A partial release is not
possible with the common forms of air brake.
"Application" closes off the connection from the main reservoir and opens the brake
pipe to atmosphere. The brake pipe pressure is reduced as air escapes. The driver
(and any observer in the know) can often hear the air escaping.
Most driver's brake valves were fitted with an "Emergency" position. Its operation
is the same as the "Application" position, except that the opening to atmosphere is
larger to give a quicker application.
FEED VALVE
To ensure that brake pipe pressure remains at the required level, a feed valve is
connected between the main reservoir and the brake pipe when the "Running"
position is selected. This valve is set to a specific operating pressure.
32 | P a g e
EQUALISING RESEVOIR
This is a small pilot reservoir used to help the driver select the right pressure in the
brake pipe when making an application. When an application is made, moving the
brake valve handle to the application position does not discharge the brake pipe
directly, it lets air out of the equalising reservoir. The equalising reservoir is
connected to a relay valve which detects the drop in pressure and automatically let’s
air escape from the brake pipe until the pressure in the pipe is the same as that in the
equalising reservoir.
The equalising reservoir overcomes the difficulties which can result from a long
brake pipe. A long pipe will mean that small changes in pressure selected by the
driver to get a low rate of braking will not be seen on his gauge until the change in
pressure has stabilized along the whole train. The equalizing reservoir and
associated relay valve allows the driver to select a brake pipe pressure without
having to wait for the actual pressure to settle down along a long brake pipe before
he gets an accurate reading.
Brake Pipe
The pipe running the length of the train, which transmits the variations in pressure
required to control the brake on each vehicle. It is connected between vehicles by
flexible hoses, which can be uncoupled to allow vehicles to be separated. The use
of the air system makes the brake "fail safe", i.e. loss of air in the brake pipe will
cause the brake to apply. Brake pipe pressure loss can be through a number of
causes as follows:
 A controlled reduction of pressure by the driver
 A rapid reduction by the driver using the emergency position on his brake
valve
 A rapid reduction by the conductor who has an emergency valve at his
position
 A rapid reduction by passengers using an emergency system to open a valve
 A rapid reduction through a burst pipe or hose
 A rapid reduction when the hoses part as a result of the train becoming
parted or derailed.
ANGLE COCK
At the ends of each vehicle, "angle cocks" are provided to allow the ends of the
brake pipe hoses to be sealed when the vehicle is uncoupled. The cocks prevent
the air being lost from the brake pipe.
33 | P a g e
COUPLED HOSES
The brake pipe is carried between adjacent vehicles through flexible hoses. The
hoses can be sealed at the outer ends of the train by closing the angle cocks.
BRAKE CYLINDER
Each vehicle has at least one brake cylinder. Sometimes two or more are
provided. The movement of the piston contained inside the cylinder operates the
brakes through links called "rigging". The rigging applies the blocks to the
wheels. Some modern systems use disc brakes. The piston inside the brake
cylinder moves in accordance with the change in air pressure in the cylinder.
AUXILIARY RESEVOIR
The operation of the air brake on each vehicle relies on the difference in pressure
between one side of the triple valve piston and the other. In order to ensure there is
always a source of air available to operate the brake, an "auxiliary reservoir" is
connected to one side of the piston by way of the triple valve. The flow of air into
and out of the auxiliary reservoir is controlled by the triple valve.
BRAKE BLOCK
This is the friction material which is pressed against the surface of the wheel tread
by the upward movement of the brake cylinder piston. Often made of cast iron or
some composition material, brake blocks are the main source of wear in the brake
system and require regular inspection to see that they are changed when required.
Many modern braking systems use air operated disc brakes. These operate to the
same principles as those used on road vehicles.
BRAKE RIGGING
This is the system by which the movement of the brake cylinder piston transmits
pressure to the brake blocks on each wheel. Rigging can often be complex,
especially under a passenger car with two blocks to each wheel, making a total of
sixteen. Rigging requires careful adjustment to ensure all the blocks operated from
one cylinder provide an even rate of application to each wheel. If you change one
block, you have to check and adjust all the blocks on that axle.
TRIPLE VALVE
The operation of the brake on each vehicle is controlled by the "triple valve", so
called because it originally comprised three valves - a "slide valve", incorporating
a "graduating valve" and a "regulating valve". It also has functions - to release the
brake, to apply it and to hold it at the current level of application. The triple valve
34 | P a g e
contains a slide valve which detects changes in the brake pipe pressure and
rearranges the connections inside the valve accordingly. It either:
 recharges the auxiliary reservoir and opens the brake cylinder exhaust,
 closes the brake cylinder exhaust and allows the auxiliary reservoir air to
feed into the brake cylinder
 Or holds the air pressures in the auxiliary reservoir and brake cylinder at the
current level.
The triple valve is now usually replaced by a distributor- a more sophisticated
version with built-in refinements like graduated release.
35 | P a g e
BRAKE APPLICATION
The driver has placed the brake valve in the "Application" position. This causes
air pressure in the brake pipe to escape. The loss of pressure is detected by the
slide valve in the triple valve. Because the pressure on one side (the brake pipe
side) of the valve has fallen, the auxiliary reservoir pressure on the other side has
pushed the valve (towards the right) so that the feed groove over the valve is
closed. The connection between the brake cylinder and the exhaust underneath the
slide valve has also been closed. At the same time a connection between the
auxiliary reservoir and the brake cylinder has been opened. Auxiliary reservoir air
now feeds through into the brake cylinder. The air pressure forces the piston to
move against the spring pressure and causes the brake blocks to be applied to the
wheels. Air will continue to pass from the auxiliary reservoir to the brake cylinder
until the pressure in both is equal. This is the maximum pressure the brake
cylinder will obtain and is equivalent to a full application. To get a full application
with a reasonable volume of air, the volume of the brake cylinder is usually about
40% of that of the auxiliary reservoir.
BOOGIE SECTION
This shop manufactures boogies for metro, ACEMU and Indian railways coaches.
The metro boogies are only assembled in this shop. This section of the train has to
withstand fatigue loading. Thus components fail much before they reach their yield
point. Thus a factor of safety around 10 is maintained.
The input to this section is the wheel set which is manufactured in the rail wheel
factory for the Indian railways. The boogie wheel set for the metro is imported
from voith, Germany. The frame is brought from the Siemens factory in
Aurangabad.
The side frame of the boogie is assembled using automatic submerged arc welding.
It uses a wire spool of TCMS.current:550-600A, voltage-20-25V.Granular flux is
initially poured in order to protect the weld from oxidation.

Once the welding is done, there is a hydraulic straightening machine which
removes the deformation caused due to welding, this is an important consideration
concerning the alignment of wheels. All the components of the boogie structure is
welded using MIG welding.
The braking linkages are then attached. The secondary suspension is also attached.
The bearing (roller) assembly is fitted to the wheel set.It is used to reduce friction
and also to support the journal. The parts of the bearing are heated to 398K in an
induction heater. Once the assembled bearing cools it contracts thus giving an
interference fit. There is grease applied between the parts of a bearing.

SHEET METAL
Shearing: Removal/cutting of unwanted material and retaining the required portion.
Pressing: it is operation based on the shaping of sheet metal by plastic deformation,
the deformation is achieved by forcing the sheet metal into a formed die using
punch. There are two types of pressing machines
 Punch press
 Brake press
Grinding: It is an abrasive machining process that uses grinding wheel as the
cutting tool.
Laser Cutting: is a technology which uses laser technology to cut the materials and
is used for industrial manufacturing process. Laser cutting works by directing the
output of a high power laser by computer, at the material to be cut.
The material either melts, burns or vaporizes away or is blown away by jet of gas.
Cutting gases:
 Oxygen for M.S
 Nitrogen for S.S and Al
Maximum cutting thickness for different materials are:
 Mild Steel- 20mm

MACHINING SECTION
Most of the major assemblies require machined components which is performed
here.
1. CNC turning machine-it is a computer numerically controlled lathe enclosed
in a casing. The work piece is held in place by the chuck. There is turret
head which houses different tools. For every turning operation a program is
fed. During turning the screen in the control panel indicates the
instantaneous x and z co-ordinates.
2. Stretch forming-the work piece is stretched over a die and hence takes the
shape of the die. Depending on the die shapes different formed products can
be obtained.
The machine contains two hydraulically controlled jaws which are moved
backwards such that the work piece acquires the shape of the die. Forming is
preferred to welding as it is a stress relieving operation.

TESTING DEPARTMENT (PRE)
The input to this section is from the outfitting hangar. The various tests conducted
are
 Clearance test-In this test the dimensions are checked. The coach is made to
pass through a profile. This ensures that the train can pass through tunnels,
stations etc.
 Car body leveling-the rail to floor height dimensions are checked, primary
suspension gap is checked, car to boogie clearance and secondary
suspension(the car is leveled by pumping or removing air from this
suspension)is checked (all these test will have tolerances).
 Weighment test-This test checks that the car weighs within the tolerances.
Weighment is done through the help of load cells placed under the tracks.
For one set of boogie there are four load cells used. Thus a total of sixteen
load cells are used for one car. A load cell senses the variation in stress when
the wheels are placed on it. It then converts the pressure signal received to
voltage signals. The computer then collects all the voltage signals and
converts them to weight.
 Water tightness test-Before this test is conducted it is ensured that all the
gaps are covered with sealent.Inside the car there will be inspectors to
perform the manual inspection.
 Dielectric tests-This test is done to check the insulating capacity of the
cables. An alternator is used to generate varying voltages. These voltages are
applied to different wires and the leakage currents are measured. It is
checked whether they are within the limits. The following table shows tests
for some of the wires.
Type of wires Dielectric voltage(V) Leakage current(mA)
1.communication cables 70 240
2.battery cables 1270 30

5.470V cables 2700 3
6.HV cables 3900 15
The input to the car is 25000V which is either drawn through the pantograph
or a current collector device in the third rail system. This is then stepped up
or down using transformers for various purposes.

BEML TEST TRACK
QUALITY DEPARTMENT
The work of this department runs parallel to production. The engineers in this
department form a part of the inspection team that perform the stage wise inspection
in order to clear the product to the next stage of production.
For every stage of manufacturing this department has an ITP (inspection test
plan).According to this the inspection process is carried out. The general contents of
the ITP include the following.
1. Scope-To check/inspect that the products conform to the technical specifications
and the relevant procedures.
2. Abbreviations and definitions that are used in the ITP are explained.
3. Control of applicable documents and drawings-documents and drawings which
are applicable to each inspection test are designated in the table of ITP.BEML will
also maintain the latest drawings and documents for the customer’s requirement.
4. Requirements, standards and specifications-the ITP is prepared based on technical
specifications, test methods etc.
55 | P a g e
5. General inspection/test process-All major assemblies and sub assemblies, detail
parts shall be verified by QC officials and the record for the same shall be
maintained. If there are non-conformities of products and process, inspector will
issue non-conformity report and notifies to the production and planning
departments. They rectify it and then again it is verified by the QC officials and the
record for the same shall be kept.
During the inspection there will be customer inspection points, where only after the
customer inspects and is satisfied with the product can it proceed to the next stage
of production. The inspection point will be notified to the customer through a RIT
(request for inspection/test).If the customer wants to inspect randomly he will notify
BEML. The ITP contains a flow chart indicating customer verification points. It also
contains the inspection check sheets for various components which contain
specifications that every product should confer to.
The department also conducts CVI (complete vehicle inspection test).Besides this it
also handles customer feedback information and suggestions.
STORES
• Receiving Stores:
These receive materials through the gate pass, and are sent to the concerned
departments.
• Project Stores:
These receive materials concerned to the production work.
• Non Project Stores:
These receive materials which indirectly help in the production work like
weld rods etc,.
• Stock Control Department:
This department will look after non production materials such as issuing of
clothes, medicines, books etc,.
• Salvage stores:
56 | P a g e
These collect waste materials from shop side on corner of factory premises
and are stored for the further processing.
• Rejected stores:
These collect rejected items from the various departments and send it for
further action.
The other stores are:
• Painting Store
• Cylinder Store
• Oil and Diesel Store
For identification each product in the stores has a BIN card. The BIN card indicates
the date of arrival and withdrawal of the product from the stores, net quantity and
location in the stores. Every product has a reference number. This system is common
for all the factories of BEML.
PURCHASE DEPARTMENT
The Purchase Department is decentralized and each section is responsible for the
procurement of its requirement. It handles the central excise, customs and
insurance of the products that are procured from different vendors.
On every product manufactured, the manufacturer has to pay value added tax and
excise duty(ED) which will be some percentage of cost of the goods. BEML pays
both these duties to the vendor. Since BEML also manufactures products which in
turn will be taxed upon it can credit the duty it had payed on products from the
vendors. . In the case of imported goods ED is called customs duty. Only after
paying the customs can the components be received by BEML. Products whose
customs duty is not paid are called bonded goods. These are kept in bonded
warehouses and can be de bonded after payment of the customs duty.
This department also handles the insurance regarding the products. Every product
that enters the stores is ensured.
MARKETING DEPARTMENT
57 | P a g e
BEML manufactures capital goods. These goods need not be endorsed as durable
goods are. The goods generally are concerned with the economic interests of the
country.
BEML has an all India based effective marketing network that provides customer
with immediate access to BEML’s wide range of products and services. The
company’s marketing strength and reach has enabled it to achieve a share of even
70% in the Indian market. The corporate head quarter is in Bangalore but the central
marketing unit has been shifted to KGF where most of the equipment for
commercial purpose is manufactured. It has regional offices, large number of district
offices, spare parts depots and service centers located within the country and also
abroad.
TENDERING
The customer releases the tender in all forms of mass media. There is a certain
amount of time given for all the participants to indicate their participation along
with their quotations. Among these participants it is checked whether they have the
technical capabilities to manufacture the product. Others are rejected. The second
fact taken into consideration is whether they can deliver the product within the
stipulated time. This is negotiable top some extent. The final consideration is the
price. The lowest bidder gets the contract. Failure to deliver the product will attract
liquidity damages. For the metro the tendering process is similar but it is done
through ICB(international competitive bidding).
The payment can be made either by stage payment (payment given after every stage
of manufacturing) or after the complete product is manufactured (10% is given after
commissioning of the product). In 2012 the railway division generated 1375 crores
of revenue and 37 crores of profit. The profit made is used to pay the dividends of
shareholders.
R&D DEPARTMENT
58 | P a g e
This department is involved in the designing of the product components. The metro
division is generally handled by this department. The engineers are divided among
themselves into four groups
1. Car body.
2. Boogie.
3. Electrical.
4. Outfitting.
They also set the inspection standards and passing criteria for various test
procedures. It is also required to check that purchases satisfy the technical
requirements.
MATERIAL TESTING AND CHEMICAL LABOROTARY
The laboratories mainly conduct production oriented tests and to some extent tests
on the incoming materials to the factory as and when required by different
departments. Usually the vendor along with the products shows the test reports
conducted by him. It is generally accepted, but incase certain departments want it
tested again it is the function of these labs to conduct the specific tests and give the
result accordingly. Some of the tests conducted are mentioned below.
1. Shear tensile test of spot weld-this test is carried out on a universal testing
machine. The specimen is placed between the grips as shown in the picture below.
The load is then applied gradually. The deflection is indicated by the dial gages.
The ultimate load taken by the specimen is noted.

DEFENSE AND AEROSPACE
The technology division caters ninety percent of its services to the army and the
rest along with other labs to the air force and navy.
Some of the major projects that the department has participated are mentioned
below
1. Launch and recovery system of AEU-This system was developed in order to
launch and retrieve the underwater submarine to the mother ship. The staffs
from this department were present for the trials held. Today it is already in
service with the navy.
2. Gas cooling system-The exhaust released by the vessel makes it an easy
target for enemy heat seeking missiles. Thus the navy wanted a system that
will erase the heat signal. This system runs on battery power and uses sea
water for its functioning as it is in abundance. It is mounted on the exhaust
of the ship.
3. AAV (active antenna array) unit-This antenna unit is mounted on a
reconnaissance aircraft and is used to prevent the enemy from jamming the
communication system. The bird hit test was conducted as well as the
structural analysis of the fixture.
4. Land mine detector-there are land mines designed to explode when metal
passes over them. These mines can be very dangerous for tanks. These can
be detected.
5. Tank repair vehicle-whenever tanks in the battlefield are damaged or
become immobile, these vehicles help to bring them back to safety.
6. Spyder Rafael project-the technology department developed a double
cylinder cab raising mechanism. This was developed as the conventional
single cylinder mechanism was insufficient for raising the cab.
7. Sarvatra bridging system-often in the battlefield the tanks or any other army
vehicle may come across gorges, or small streams. In this case this bridging
system which can be temporarily constructed and de-assembled is used. It
has span of 75m.
68 | P a g e
METROLOGY DEPARTMENT
As the name suggests metrology is derived from the word meter. It deals with
measuring instruments. The main function of this department is the calibration of
all the measuring instruments used in various shops. The calibration is carried
according to Indian standards. Some of the instruments used are
1. Gauge bocks-these are used as master for calibration of vernier calipers. A
picture of it is shown below. They can come in different sizes. The desired
dimensions can be obtained by joining two or more of these. They are
available in grades which vary in their level of accuracy. Grade 2, 1,0,00 are
arranged in the increasing order of accuracy. Each of these set can cost up to
a lakh.
Gauge block set
69 | P a g e
2. Vernier calipers-these can be analog or digital. They are used for four
measurements. They are inside diameter, outside diameter, depth and step
measurements. The least count of this device ranges up to 0.01mm.
3. Thread plug gage-there are two of these gages-GO and NO-GO. These are
used to check whether the pitch and diameter of the nut is up to the required
dimensions. It also acts as a master for the ring gage. The difference between
the diameters of GO and NO-GO side defines the tolerance required.
4. Ring gauge-these are used to check whether the bolts are according to
required dimensions.
5. Inside and outside micrometer are used to give micrometer accuracy.
Vernier callipers

PRODUCT DESIGN (PD) DEPARTMENT
Once the contract is obtained by the marketing division it is reviewed in the pre-
contract review meeting in which all the managers of different departments discuss
the following:
1. Delivery schedule.
2. Manufacturing capabilities and parameters.
3. Constraints should be added (if needed).
The PD department then studies the general specifications required by the
customer(a general outline of the product is given by the customer).The engineers
then come out with the required manufacturing drawings specifying the
dimensions,size,shape and the materials(BOM) to be used. These have to be
approved by the customer or his agency (RDSO in case of Indian railways).
Then a prototype of the product is made and is inspected by the customer’s agency
(RDSO) .If any changes are required it is made accordingly. Once satisfied the
customer’s agency (RDSO) gives the approval for bulk production.
The drawings are then printed in a non tear able sheet by the draftsmen, after which
nine blue prints are made of which two are retained by the department; one each is
sent to the methods planning and industrial engineering departments. The other five
72 | P a g e
are sent to the PD control rooms present in the shop floors. The department uses an
enterprise resource system (ERP) for all its activities.
ECR AND ECN
In case for any reason the manufacturing section wants to make a change in the
product, it is communicated to the PD department by an ECR (engineering change
request) through the ERP.This is then analyzed by the department, if any change is
required it is communicated to the required departments by an ECN (engineering
change notice) which specifies the change made. The old blue prints are now
replaced with the new one and again the new blue print is sent to the required
departments.
PLANNING DEPARTMENT
This department mainly performs two main functions
1. Materials planning-involves the decision to decide whether the components
required are to be manufactured in house or to be brought from vendors.
2. Facilities planning-involves plan for machineries, material flow, man hours
availability etc
3. Scheduling-based on monthly basis.
The above mentioned functions are carried by an ERP-SAP.Intially the input is
entered. Input may include the process used, quantity, material, sub-assemblies and
components, cost etc.
The output of the ERP run is the planned order and the product order which gives
cost of the entire process, components to be procured, components left in the stores,
products to be manufactured per month etc. Once any transactions are carried it is
updated accordingly.

INTERNSHIP AT BEML Limited - a learning Experience
As envisioned by our first PM, Pt. Jawaharlal Nehru, BEML Limited has proved to
be true one among the modern temples of engineering of India and BEML has
proved beyond doubt that they are no less than their competitors in the private
sector. As I have seen and experienced, there is no dearth of expertise, talent,
professionalism and dedication of the workforce towards accomplishing the tasks
and targets in meeting delivery of products to its various customer segments.
Today, I am proud to be associated with this esteemed organization as an intern and
I am fortunate to have the exposure across most of the departments and its industrial
functioning. Overall it was a good learning and rewarding experience.

knowledge into the overall functioning of the organization, human behavior in
industry and also helped us co-relate theoretical concepts of classroom and practical
approach to industrial production.
The entire duration of four weeks in BEML was professionally managed by all the
responsible persons I came across, very informative and I have no doubt, it will
retain its significance when I embrace my professional careers as an engineer.
In doing so, I gratefully acknowledge the large heartedness of this institution for
giving me an opportunity to complete this internship.

  • 17. 17 | P a g e PRODUCTION DEPARTMENT CAR BODY SHOP- Each metro car consist of six modules.  Under frame  Side wall LH  Side wall RH  End wall  Cab  Roof Each of the above mentioned components start their journey from stainless steel parts that are sub-contracted to other companies. The side wall and the roof are fabricated in the car body shop. According to the drawings both the side wall and roof are fabricated using robotic spot welding machines. The weld points are also specified in the drawing. The fixtures are welded using TIG (tungsten inert gas welding).
  • 18. 18 | P a g e LAY OUT OF METAL FABRICATION SHOP All the extra fittings are welded using TIG welding to either the roof top or the mid and end sections. Basic structure of roof top is made.It is then spot welded to the panel. End panels are fabricated,spot welded and levelling operation is done.Mid section also fabricated here.spot welding is used.locators and clamps are used to arrest the motion of the parts. DLD panels of mild steel are attached by spot welding in which workbase acts as a second electrode.hence the machine has only one electrode.
  • 19. 19 | P a g e LAY OUT OF CAR BODY SHOP Spot welding of roof sheets Serves as one of the input to the section Assembly of the entire car body shell The side frames shown below are integrated to form the side wall. Welding used is MIG welding. All the fabrications of the roof made are assembled here using MIG welding. Hardening of the shell is carried out. Electrochemical grinding is performed to remove stains of spot weld. The assembled body is washed.
  • 20. 20 | P a g e UNDER FRAME SECTION This section forms an integral part of the overall assembly as it has to support the weight of the car. This section manufactures underframes for Indian railways, sub- urban trains and metro. For the metro stainless steel is used which is in contrary to the mild steel used for Indian railways and the sub urban trains. Basic process that are involved are MIG, spot and seam welding. SEAM WELDING The three sheets are placed on a jig with the seam welding machine running along the side of the jig. The X in the figure indicate the initial tact weld. Once this is done a complete weld as indicated by the line is done.
  • 21. 21 | P a g e The seam welding machine consist of a roller which has high electrical resistance.it also has a supply of cooling water which helps in solidifying the weld immediately. Principle-when the power supply is switched on due to the high resistance of the roller wheel, heat is generated. When this roller is touched to the SS sheets they melt and solidify joining the two sheets.
  • 22. 22 | P a g e The underframe consists of two end blocks and a mid-block. All these are made from basic components and welded either using spot or MIG welding’s as per drawings. The body bolster and the center sill are made of mild steel and separately made before welding to the underframe. KEYSTONE WELDING MACHINE-the weld points are initially fed to the machine. The machine stores them as (x,y,z) co-ordinates. For each program of welds there are 34 points (17 done by each robot).there is a pneumatically activated holding device which keeps the surface of the sheet on the datum. The operator uses the joystick to move the robots. The robots have their own NC codes which the computer processes. UNDER FRAME ASSEMBLY
  • 23. 23 | P a g e
  • 24. 24 | P a g e END UNDER FRAME The end under frame consists of the following components 1. Body bolster. 2. Center sill. 3. Rear assembly of center sill. 4. Support beams. 5. Anti-climbers. Shown below is under frame with the end under section visible. The metro trains use a similar end under frame.
  • 25. 25 | P a g e The sub-assemblies of the body bolster and center sill are welded using MIG welding. Initially tact weld is performed then continuous weld is done. The attaching surface of the body bolster is machined by a face mill in the machining section. All the components are then welded using MIG welding. Vertical welding is also performed by using a jig that can rotate 360 degrees. After vertical welding the given assembly is turned 180 degrees and welding on the underside is done.

  • 30. 30 | P a g e PIPING AND BRAKING The air braking system is used in the metro car.it is an electro-pneumatic controlled system. The main compressor unit is located in the trailer car. Power required to run the main compressor is taped from the electrical grid using the pantograph. There is also an auxiliary compressor unit for lifting and dropping of the pantograph. The voltage required for the compressor is stepped down using a step down transformer. The metro train system comes equipped with three brakes 1. Service brake 2. Emergency brake 3. Parking brake.
  • 31. 31 | P a g e The main parts of the braking system are COMPRESSOR The pump which draws air from atmosphere and compresses it for use on the train. Its principal use is for the air brake system, although compressed air has a number of other uses on trains. MAIN RESEVOIR Storage tank for compressed air for braking and other pneumatic systems. DRIVERS BRAKE VALVE The means by which the driver controls the brake. The brake valve will have (at least) the following positions: "Release", "Running", "Lap" and "Application" and "Emergency". There may also be a "Shut Down" position, which locks the valve out of use. The "Release" position connects the main reservoir to the brake pipe. This raises the air pressure in the brake pipe as quickly as possible to get a rapid release after the driver gets the signal to start the train. In the "Running" position, the feed valve is selected. This allows a slow feed to be maintained into the brake pipe to counteract any small leaks or losses in the brake pipe, connections and hoses. "Lap" is used to shut off the connection between the main reservoir and the brake pipe and to close off the connection to atmosphere after a brake application has been made. It can only be used to provide a partial application. A partial release is not possible with the common forms of air brake. "Application" closes off the connection from the main reservoir and opens the brake pipe to atmosphere. The brake pipe pressure is reduced as air escapes. The driver (and any observer in the know) can often hear the air escaping. Most driver's brake valves were fitted with an "Emergency" position. Its operation is the same as the "Application" position, except that the opening to atmosphere is larger to give a quicker application. FEED VALVE To ensure that brake pipe pressure remains at the required level, a feed valve is connected between the main reservoir and the brake pipe when the "Running" position is selected. This valve is set to a specific operating pressure.
  • 32. 32 | P a g e EQUALISING RESEVOIR This is a small pilot reservoir used to help the driver select the right pressure in the brake pipe when making an application. When an application is made, moving the brake valve handle to the application position does not discharge the brake pipe directly, it lets air out of the equalising reservoir. The equalising reservoir is connected to a relay valve which detects the drop in pressure and automatically let’s air escape from the brake pipe until the pressure in the pipe is the same as that in the equalising reservoir. The equalising reservoir overcomes the difficulties which can result from a long brake pipe. A long pipe will mean that small changes in pressure selected by the driver to get a low rate of braking will not be seen on his gauge until the change in pressure has stabilized along the whole train. The equalizing reservoir and associated relay valve allows the driver to select a brake pipe pressure without having to wait for the actual pressure to settle down along a long brake pipe before he gets an accurate reading. Brake Pipe The pipe running the length of the train, which transmits the variations in pressure required to control the brake on each vehicle. It is connected between vehicles by flexible hoses, which can be uncoupled to allow vehicles to be separated. The use of the air system makes the brake "fail safe", i.e. loss of air in the brake pipe will cause the brake to apply. Brake pipe pressure loss can be through a number of causes as follows:  A controlled reduction of pressure by the driver  A rapid reduction by the driver using the emergency position on his brake valve  A rapid reduction by the conductor who has an emergency valve at his position  A rapid reduction by passengers using an emergency system to open a valve  A rapid reduction through a burst pipe or hose  A rapid reduction when the hoses part as a result of the train becoming parted or derailed. ANGLE COCK At the ends of each vehicle, "angle cocks" are provided to allow the ends of the brake pipe hoses to be sealed when the vehicle is uncoupled. The cocks prevent the air being lost from the brake pipe.
  • 33. 33 | P a g e COUPLED HOSES The brake pipe is carried between adjacent vehicles through flexible hoses. The hoses can be sealed at the outer ends of the train by closing the angle cocks. BRAKE CYLINDER Each vehicle has at least one brake cylinder. Sometimes two or more are provided. The movement of the piston contained inside the cylinder operates the brakes through links called "rigging". The rigging applies the blocks to the wheels. Some modern systems use disc brakes. The piston inside the brake cylinder moves in accordance with the change in air pressure in the cylinder. AUXILIARY RESEVOIR The operation of the air brake on each vehicle relies on the difference in pressure between one side of the triple valve piston and the other. In order to ensure there is always a source of air available to operate the brake, an "auxiliary reservoir" is connected to one side of the piston by way of the triple valve. The flow of air into and out of the auxiliary reservoir is controlled by the triple valve. BRAKE BLOCK This is the friction material which is pressed against the surface of the wheel tread by the upward movement of the brake cylinder piston. Often made of cast iron or some composition material, brake blocks are the main source of wear in the brake system and require regular inspection to see that they are changed when required. Many modern braking systems use air operated disc brakes. These operate to the same principles as those used on road vehicles. BRAKE RIGGING This is the system by which the movement of the brake cylinder piston transmits pressure to the brake blocks on each wheel. Rigging can often be complex, especially under a passenger car with two blocks to each wheel, making a total of sixteen. Rigging requires careful adjustment to ensure all the blocks operated from one cylinder provide an even rate of application to each wheel. If you change one block, you have to check and adjust all the blocks on that axle. TRIPLE VALVE The operation of the brake on each vehicle is controlled by the "triple valve", so called because it originally comprised three valves - a "slide valve", incorporating a "graduating valve" and a "regulating valve". It also has functions - to release the brake, to apply it and to hold it at the current level of application. The triple valve
  • 34. 34 | P a g e contains a slide valve which detects changes in the brake pipe pressure and rearranges the connections inside the valve accordingly. It either:  recharges the auxiliary reservoir and opens the brake cylinder exhaust,  closes the brake cylinder exhaust and allows the auxiliary reservoir air to feed into the brake cylinder  Or holds the air pressures in the auxiliary reservoir and brake cylinder at the current level. The triple valve is now usually replaced by a distributor- a more sophisticated version with built-in refinements like graduated release.
  • 35. 35 | P a g e BRAKE APPLICATION The driver has placed the brake valve in the "Application" position. This causes air pressure in the brake pipe to escape. The loss of pressure is detected by the slide valve in the triple valve. Because the pressure on one side (the brake pipe side) of the valve has fallen, the auxiliary reservoir pressure on the other side has pushed the valve (towards the right) so that the feed groove over the valve is closed. The connection between the brake cylinder and the exhaust underneath the slide valve has also been closed. At the same time a connection between the auxiliary reservoir and the brake cylinder has been opened. Auxiliary reservoir air now feeds through into the brake cylinder. The air pressure forces the piston to move against the spring pressure and causes the brake blocks to be applied to the wheels. Air will continue to pass from the auxiliary reservoir to the brake cylinder until the pressure in both is equal. This is the maximum pressure the brake cylinder will obtain and is equivalent to a full application. To get a full application with a reasonable volume of air, the volume of the brake cylinder is usually about 40% of that of the auxiliary reservoir. BOOGIE SECTION This shop manufactures boogies for metro, ACEMU and Indian railways coaches. The metro boogies are only assembled in this shop. This section of the train has to withstand fatigue loading. Thus components fail much before they reach their yield point. Thus a factor of safety around 10 is maintained. The input to this section is the wheel set which is manufactured in the rail wheel factory for the Indian railways. The boogie wheel set for the metro is imported from voith, Germany. The frame is brought from the Siemens factory in Aurangabad. The side frame of the boogie is assembled using automatic submerged arc welding. It uses a wire spool of TCMS.current:550-600A, voltage-20-25V.Granular flux is initially poured in order to protect the weld from oxidation.

  • 51. 51 | P a g e TESTING DEPARTMENT (PRE) The input to this section is from the outfitting hangar. The various tests conducted are  Clearance test-In this test the dimensions are checked. The coach is made to pass through a profile. This ensures that the train can pass through tunnels, stations etc.  Car body leveling-the rail to floor height dimensions are checked, primary suspension gap is checked, car to boogie clearance and secondary suspension(the car is leveled by pumping or removing air from this suspension)is checked (all these test will have tolerances).  Weighment test-This test checks that the car weighs within the tolerances. Weighment is done through the help of load cells placed under the tracks. For one set of boogie there are four load cells used. Thus a total of sixteen load cells are used for one car. A load cell senses the variation in stress when the wheels are placed on it. It then converts the pressure signal received to voltage signals. The computer then collects all the voltage signals and converts them to weight.  Water tightness test-Before this test is conducted it is ensured that all the gaps are covered with sealent.Inside the car there will be inspectors to perform the manual inspection.  Dielectric tests-This test is done to check the insulating capacity of the cables. An alternator is used to generate varying voltages. These voltages are applied to different wires and the leakage currents are measured. It is checked whether they are within the limits. The following table shows tests for some of the wires.

  • 54. 54 | P a g e BEML TEST TRACK QUALITY DEPARTMENT The work of this department runs parallel to production. The engineers in this department form a part of the inspection team that perform the stage wise inspection in order to clear the product to the next stage of production. For every stage of manufacturing this department has an ITP (inspection test plan).According to this the inspection process is carried out. The general contents of the ITP include the following. 1. Scope-To check/inspect that the products conform to the technical specifications and the relevant procedures. 2. Abbreviations and definitions that are used in the ITP are explained. 3. Control of applicable documents and drawings-documents and drawings which are applicable to each inspection test are designated in the table of ITP.BEML will also maintain the latest drawings and documents for the customer’s requirement. 4. Requirements, standards and specifications-the ITP is prepared based on technical specifications, test methods etc.
  • 55. 55 | P a g e 5. General inspection/test process-All major assemblies and sub assemblies, detail parts shall be verified by QC officials and the record for the same shall be maintained. If there are non-conformities of products and process, inspector will issue non-conformity report and notifies to the production and planning departments. They rectify it and then again it is verified by the QC officials and the record for the same shall be kept. During the inspection there will be customer inspection points, where only after the customer inspects and is satisfied with the product can it proceed to the next stage of production. The inspection point will be notified to the customer through a RIT (request for inspection/test).If the customer wants to inspect randomly he will notify BEML. The ITP contains a flow chart indicating customer verification points. It also contains the inspection check sheets for various components which contain specifications that every product should confer to. The department also conducts CVI (complete vehicle inspection test).Besides this it also handles customer feedback information and suggestions. STORES • Receiving Stores: These receive materials through the gate pass, and are sent to the concerned departments. • Project Stores: These receive materials concerned to the production work. • Non Project Stores: These receive materials which indirectly help in the production work like weld rods etc,. • Stock Control Department: This department will look after non production materials such as issuing of clothes, medicines, books etc,. • Salvage stores:
  • 56. 56 | P a g e These collect waste materials from shop side on corner of factory premises and are stored for the further processing. • Rejected stores: These collect rejected items from the various departments and send it for further action. The other stores are: • Painting Store • Cylinder Store • Oil and Diesel Store For identification each product in the stores has a BIN card. The BIN card indicates the date of arrival and withdrawal of the product from the stores, net quantity and location in the stores. Every product has a reference number. This system is common for all the factories of BEML. PURCHASE DEPARTMENT The Purchase Department is decentralized and each section is responsible for the procurement of its requirement. It handles the central excise, customs and insurance of the products that are procured from different vendors. On every product manufactured, the manufacturer has to pay value added tax and excise duty(ED) which will be some percentage of cost of the goods. BEML pays both these duties to the vendor. Since BEML also manufactures products which in turn will be taxed upon it can credit the duty it had payed on products from the vendors. . In the case of imported goods ED is called customs duty. Only after paying the customs can the components be received by BEML. Products whose customs duty is not paid are called bonded goods. These are kept in bonded warehouses and can be de bonded after payment of the customs duty. This department also handles the insurance regarding the products. Every product that enters the stores is ensured. MARKETING DEPARTMENT
  • 57. 57 | P a g e BEML manufactures capital goods. These goods need not be endorsed as durable goods are. The goods generally are concerned with the economic interests of the country. BEML has an all India based effective marketing network that provides customer with immediate access to BEML’s wide range of products and services. The company’s marketing strength and reach has enabled it to achieve a share of even 70% in the Indian market. The corporate head quarter is in Bangalore but the central marketing unit has been shifted to KGF where most of the equipment for commercial purpose is manufactured. It has regional offices, large number of district offices, spare parts depots and service centers located within the country and also abroad. TENDERING The customer releases the tender in all forms of mass media. There is a certain amount of time given for all the participants to indicate their participation along with their quotations. Among these participants it is checked whether they have the technical capabilities to manufacture the product. Others are rejected. The second fact taken into consideration is whether they can deliver the product within the stipulated time. This is negotiable top some extent. The final consideration is the price. The lowest bidder gets the contract. Failure to deliver the product will attract liquidity damages. For the metro the tendering process is similar but it is done through ICB(international competitive bidding). The payment can be made either by stage payment (payment given after every stage of manufacturing) or after the complete product is manufactured (10% is given after commissioning of the product). In 2012 the railway division generated 1375 crores of revenue and 37 crores of profit. The profit made is used to pay the dividends of shareholders. R&D DEPARTMENT

PRODUCT DESIGN (PD) DEPARTMENT Once the contract is obtained by the marketing division it is reviewed in the pre- contract review meeting in which all the managers of different departments discuss the following: 1. Delivery schedule. 2. Manufacturing capabilities and parameters. 3. Constraints should be added (if needed). The PD department then studies the general specifications required by the customer(a general outline of the product is given by the customer).The engineers then come out with the required manufacturing drawings specifying the dimensions,size,shape and the materials(BOM) to be used. These have to be approved by the customer or his agency (RDSO in case of Indian railways). Then a prototype of the product is made and is inspected by the customer’s agency (RDSO) .If any changes are required it is made accordingly. Once satisfied the customer’s agency (RDSO) gives the approval for bulk production.

ECR AND ECN In case for any reason the manufacturing section wants to make a change in the product, it is communicated to the PD department by an ECR (engineering change request) through the ERP.This is then analyzed by the department, if any change is required it is communicated to the required departments by an ECN (engineering change notice) which specifies the change made. The old blue prints are now replaced with the new one and again the new blue print is sent to the required departments. PLANNING DEPARTMENT This department mainly performs two main functions 1. Materials planning-involves the decision to decide whether the components required are to be manufactured in house or to be brought from vendors. 2. Facilities planning-involves plan for machineries, material flow, man hours availability etc 3. Scheduling-based on monthly basis. The above mentioned functions are carried by an ERP-SAP.Intially the input is entered. Input may include the process used, quantity, material, sub-assemblies and components, cost etc. The output of the ERP run is the planned order and the product order which gives cost of the entire process, components to be procured, components left in the stores, products to be manufactured per month etc. Once any transactions are carried it is updated accordingly.

In addition, the exposure gave me the practical knowledge into the overall functioning of the organization, human behavior in industry and also helped us co-relate theoretical concepts of classroom and practical approach to industrial production. The entire duration of four weeks in BEML was professionally managed by all the responsible persons I came across, very informative and I have no doubt, it will retain its significance when I embrace my professional careers as an engineer. In doing so, I gratefully acknowledge the large heartedness of this institution for giving me an opportunity to complete this internship.
