Resistance Welders

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
