What is resistance welding?
It is a joining method in which an object to be welded are sandwiched between electrodes, pressed appropriately, and melted and welded by the "resistive heat" generated while electric current is passing through.
As the total cost is low and the welding time is short compared toother joining methods, it is widely used in various applications.
Basic configuration of a resistance welder and the role of each part
Welding Power Supply controls the amount, time, and waveform of the electric current
Welding Transformer converts the current from the power supply into a larger current
Welding Head Controls the pressure to be applied
Welding Electrode contacts the object to be welded to apply pressure and electric current
