Background technique

At present, the existing friction welding equipment is mainly used for welding metal workpieces with high strength such as steel parts. Therefore, for metal workpieces with relatively low mechanical strength, the existing friction welding equipment is used for friction welding, such as fixtures. If the clamp is too tight, it will cause deformation of the metal workpiece; if the clamp is too loose, it will cause the metal workpiece to fall, which cannot guarantee the welding quality of the welded joint. Moreover, when the existing friction welding equipment performs welding, the welding surface of the welding workpiece needs to be cleaned beforehand. The process is complicated and wastes man-hours.
