Electric resistance welding The world owes the invention of electric resistance and spot welding to Englishman Elihu Thomson. This engineer has several patents in the field of spot welding to his name.
Electric resistance welding consists in assembling by autogenous fusion the parts to be welded under the pressure of two metal parts. Who says welding says heat, with resistance welding the heat necessary for welding is provided by the Joule effect (which is the thermal manifestation of electrical resistance, this heat occurs when an electric current passes through any material conductor) of a current of high intensity and low voltage, passing through the parts to be assembled. Indeed, it takes a lot of amps and little voltage. The application of a forging force makes it possible to ensure the metallic interpenetration.
