DEPOSITION RATES, ELECTRODE EFFICIENCY, AND ELECTRODE WELD METAL RECOVERY!
WHAT ARE THE DIFFERENCES?
Deposition Rates
The deposition rate of a welding consumable (electrode, wire or rod) is the rate at which weld metal is deposited (melted) onto a metal surface.
Deposition rate is expressed in kilograms per hour (kg/hr).
Depositionrateisbasedoncontinuousoperation,notallowingforstopsandstartssuchas,electrodechangeovers,chippingslag,cleaningspatter,
machine adjustments or other reasons.
When welding current is increased so to does the deposition rate. When electrical stick out is increased in the case of GMAW and FCAW the
deposition rate will also increase.
Deposition rates are calculated by doing actual welding tests, and the following shows the formula for measuring deposition rates.
Deposition Rate = Weight of test plate before welding - Weight of test plate after welding ÷ Measured period of time (normally 60 seconds).
e.g. Plate before welding: 2kg - 2.95kg Plate after welding = 95grams, welded in 60 seconds. 95grams x 60/1000 = 5.7kg/hr.
ELECTRODE EFFICIENCY (DEPOSITION EFFICIENCY)
Technically to ISO 2401-1972 electrode efficiency (AS/NZS 1553.1: 1995 deposition efficiency) is the difference between the weight of the weld
metaldepositedandtheweightofthefillermetalconsumed(notincludingfluxandstubends)inmakingtheweld. Theefficiencyofanelectrodeis
calculated by using the following formula;
Electrode Efficiency % to ISO 2401and AS/NZS 1553.1 =
Weight of test plate including weld metal - Weight of test plate before welding X 100
Mass of the Core Wire of 5 electrodes - Weight of core wire of the 5 stub ends
e.g. Ferrocraft 22 Ø3.2mm x 380mm.
Plate before welding: 2kg - 2.167kg Plate after welding = 167grams,
weightoffive(5)electrodecorewires,Ø3.2mmx380mmlongbeforewelding
= 124grams,
weightoffive(5)electrodestubends,Ø3.2mmx50mmlongafterwelding=
16.3grams,
167grams ÷ 107.7grams x 100 = 155.06% Electrode Efficiency (Deposition
Efficiency).
e.g. Satincraft 13 Ø4mm x 380mm.
Plate before welding: 2kg - 2.15kg Plate after welding = 150grams,
weightoffive(5)electrodecorewires,Ø4mmx380mmlongbeforewelding=
188grams,
weight of five (5) electrode stub ends, Ø4mm x 50mm long after welding =
24.7grams,
150grams ÷ 163.3grams x 100 = 91.85% Electrode Efficiency (Deposition
Efficiency).
ELECTRODE WELD METAL RECOVERY (PROCESS EFFICIENCY)
ElectrodeweldmetalrecoverytoISO2401-1972allowsustocalculatetheamountofweldingconsumablewhichwillactuallybedepositedintothe
finished weld metal less any waste such as, stub ends, slag and spatter not adhered to the test plate.
Anexampleiswhen100kgsofelectrodesareusedwithaquotedefficiencyof60%,thenetresultisthatonly60kgoftheweightofthatelectrodewill
actually end up in the deposited weld metal. The remaining 40% (40kg) of the electrode is waste.
Toachieveweldmetalrecoveryratespracticaltestsarecarriedoutbyweighingthetestplatebeforeandafterwelding,weighingtheconsumables
before welding and then using the following formula allowing for 50mm stub ends. If the welder discards more than 50mm stub ends than the
recovery rate (process efficiency) will be lower.
Weld Metal Recovery % to ISO 2401 =
Weight of test plate before welding - Weight of test plate after welding X 100
Weight of the Consumable
e.g. Satincraft 13 Ø4mm x 380mm.
Plate before welding: 2kg - 2.15kg Plate after welding = 150grams,
weight of five (5) electrodes, Ø4mm x 380mm long before welding =
261.20grams,
150grams ÷ 261.20grams x 100 = 57.43% Weld Metal Recovery (Process
Efficiency).
e.g. Ferrocraft 22 Ø3.2mm x 380mm.
Plate before welding: 2kg - 2.167kg Plate after welding = 167grams,
weight of five (5) electrodes, Ø3.2mm x 380mm long before welding =
281.50grams,
167grams ÷ 281.50grams x 100 = 59.33% Weld Metal Recovery (Process
Efficiency).

MANUAL ARC ELECTRODE CONSUMPTION CALCULATOR GUIDE
Basis of Calculations
Electrode requirements have been calculated as follows:
Where M = Mass of electrodes required
D = Mass of weld metal to be deposited
E = Proportion of electrode lost
M = D
1 - E
Toarriveatthemassofweldmetaltobedepositeditisnecessarytocalculate
first the volume of metal to be added (area of the cross section of the weld
multiplied by the length). This volumetric value is converted to mass by
multiplying by the factor 0.0079 kilograms per cubic centimetre for steel.
Instructions for Use of this Data
The following tables provide data on the approximate mass in kilograms
required of the different types of electrodes for welding the various weld
