Resistance welding is a method of welding by applying pressure to the weldment through electrodes and by using resistance heat generated by current passing through the contact points, also called contact welding. During welding, the workpieces are pressed between two electrodes, and a current is applied for a certain time. The resistance heat generated by the current passing through the contact surface and adjacent areas of the work-piece is used to heat it locally to the plastic state or melting state. The combination of materials is formed under the pressure state (Fig. 1). Its physical essence is to use the resistance heat generated by the current and the plastic deformation under the action of pressure. After a certain period of time, it makes the metal atoms on the two separate surfaces of the welding area close to the lattice distance, forming a metal bond. During the process, enough common grains are produced on the bonding surface to form a welding joint.
