Spot Welding

4.
Spot Welding...In Spot Welding the pieces to be joined areclamped between two electrodes under force,and an electrical current is sent through them.Force is applied before, during, and afterthe application of current to prevent arcing atthe work piece.In spot welding fusion of faying surfaces ofa lap joint is achieved at one location byopposing electrodes

Advantages of Spot Welding Spot welding is quick and easy No need to use any fluxes or filler metal Multiple sheets joined together at the same time. No dangerous open flame Saves production costs.

Projection Welding

9.
Projection WeldingIn Projection welding size and shape of individualwelds are determined by the presence of projections,embossments or intersections on the metals to bejoined. Metals are heated and coalescence is achieved notthrough the use of an arc, but through the metals’resistance to electrical currents passing through themas they are held together with pressure by electrodes.In projection welding the pieces to be joined areclamped between two electrodes under force, ananelectrical current is sent through them.

Advantages of Projection Welding Simultaneously we can makeany number of welds in heaviermaterials easily. Welding can be made in metalsthat are too thick to be joined byspot welding. Lower Electrode Maintenance. Lower amount of current andpressure needs to joint metals. Faster and Quicker and used inmass production
