Resistance welding is a method of welding by locally heating a weldment and pressurizing the weldment while using resistance heat generated by passing current through the weldment and a contact part as a heat source. During welding, no metal filling is needed, the productivity is high, the deformation of the weldment is small, and the automation is easy to realize.

Resistance welding is generally a welding method in which workpieces are subjected to a certain electrode pressure and the contact surface between the two workpieces is melted by resistance heat generated when an electric current passes through the workpieces to effect connection. A larger current is typically used. In order to prevent arcing at the interface and to forge the weld metal, pressure is applied throughout the welding process. In performing this type of resistance welding, the surface quality of the workpiece to be welded is important to obtain stable welding quality.
