Product Description

Auto Body Manufacture Spot Welding Sheet Metal Machine​



With the development of aerospace, electronics, automobiles, household appliances and other industries, resistance welding has received more and more attention. [4] At the same time, higher requirements are put forward for the quality of resistance welding. Fortunately, the development of China's microelectronics technology and the development of high-power thyristors and rectifiers have provided conditions for the improvement of resistance welding technology. China has produced secondary rectifier welding machines with excellent performance. The control box composed of integrated circuits and microcomputers has been used for the matching of new welding machines and the transformation of old welding machines. Advanced closed-loop monitoring technologies such as constant current, dynamic resistance, and thermal expansion have begun to be popularized and applied in production. All this will help improve the quality of resistance welding and expand its application areas.

Resistance welding metal

(1) When the nugget is formed, it is always surrounded by a plastic ring, the molten metal is isolated from the air, and the metallurgical process is simple.

(2) The heating time is short and the heat is concentrated, so the heat-affected zone is small, and the deformation and stress are also small. Usually, it is not necessary to arrange the correction and heat treatment process after welding.

(3) No filler metal such as welding wire, welding rod, and welding materials such as oxygen, acetylene, hydrogen, etc. are required, and the welding cost is low.
