ELECTRODES FOR RESISTANCE WELDING AND METHOD OF USE THEREOF
摘要:
A hybrid electrode for resistance spot welding and a method of resistance welding are provided. The hybrid electrode comprises a pin and a collar member. The pin comprises an electrically conductive material and a pin contact surface. The collar member comprises a material that is at least one of less electrically conductive than the electrically conductive material of the pin and less thermally conductive than the electrically conductive material of the pin. The collar member comprises a collar member contact surface, and defines an inner cavity and a longitudinal axis. The pin is at least partially disposed in the inner cavity and the pin contact surface extends away from the collar member and is offset a distance along the longitudinal axis from the collar member contact surface.
