Spot Welding

Spot welding, or resistance spot welding, is a resistance welding operation used for joining metal surfaces.

It is a crucial process in the manufacturing of automobiles, metal furniture, appliances, and a variety of other sheet metal-based products. In a spot welding process, two metal surfaces which are to be joined are first pressed together by opposing electrodes, then current is supplied to them for a brief period. The current melts the metal where the two surfaces touch each other, thus fusing them together.

Due to the nature of this welding process, it is ideal for welding sheet metal parts thinner than 3 mm.
