Arc Spot Welding
In this process, coalescence at the overlapping surfaces is produced in one spot by heating with an electric arc between an electrode and the work. The weld is made without making a hole in either member. Filler metal or a shielding gas or flux may or may not be used. Using either of the manual metal arc or GTAW and GMAW processes produces the arc. Arc spot welding by the CO2 process is widely used now a days, for which the equipment is provided with the necessary controls to achieve consistent spot welds. While electric resistance spot welding requires access from both sides of the overlapping plates, arc spot welding can be made from one side only.
