Spot welding (RSW) is a process in which contacting metal surfaces are joined by heat from resistance to electric current flow. Work pieces are held together under pressure exerted by electrodes.

is resistance welding another name for spot welding?

cggurumanjunath · Answer

don't give medal understand the process first !

cggurumanjunath · Answer

Resistance Welding

Electric resistance welding (RW) refers to a group of welding processes, such as spot and seam welding, that produce coalescence of faying surfaces where heat to form the weld is generated by the resistance of the welding current through the workpieces. Some factors influencing heat or welding temperatures are the proportions of the workpieces, the electrode materials, electrode geometry, electrode pressing force, weld current, and weld time.

Spot welding is when you join two parrallel metal surfaces together by passing an electric current between them using electrodes placed opposite eachother with the metal sandwiched between them with pressure.  The two pieces of metal are joined at the "spot" where metal from both pieces flowed together.  Butt welding is where two pieces of metal are put together (say at a 90 degree angle for example) and some form of welding (gas or arc) is used to flow metal between each piece where they come in contact (making a fillet).
