[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic waves. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space.

[0003] The existing resistance welding refers to a method of using the resistance heat generated by the current passing through the weldment and the contact point as a heat source to locally heat the weldment and pressurize it for welding. During welding, no filler metal is required, the productivity is high, the weldment deformation is small, and it is easy to realize automation. Resistance welding uses the resistance heat effect generated by the current flowing through the contact surface of the workpiece and the adjacent area to heat it to a molten or plastic state to form a metal bond.
