Resistance welding is a thermo-electric process in which heat is generated at the interface of the parts to be joined by passing an electrical current through the parts for a precisely controlled time
The Stored Energy welding power supply – commonly called a Capacative Discharge Welder or CD Welder – extracts energy from the power line over a period of time and stores it in welding capacitors. Thus, the effective weld energy is independent of line voltage fluctuations. This stored energy is rapidly discharged through a pulse transformer

Resistance welding. Resistance welding is a process in which heat is generated at the interface by passing an electric current through it. It is performed under control time and pressure. The term is derived from the fact that the resistance between the workpiece and electrodes are used to generate the heat at the interface.
