Currently browsing: Resistance Welding

Challenge: Welding quality of stranded wires is desired to be improved, and loosening of wires is desired to be eliminated.

The object to be joined is held down and the electric current is flown while the pressure is being applied, and heat is generated by resistance heating.

Spot Welding is a fusion welding process with heat generation at the joint by the resistance of the work to the flow of electricity. Force is applied before, during, and after the application of current and melting occurs at the faying surfaces during welding.

Resistance welder sandwiches an object to be welded by the welding electrodes, andapplies electric current while applying pressure.
