[0002] A battery case is a device or outer case used to accommodate and protect the internal structure of a battery, and is an essential part of battery accessories. The welding of the battery case is usually carried out by friction welding. The heat generated by friction softens the materials at the welding part, mixes the materials and forms a firm welded joint. This method has no spatter and soot, does not require adding welding wires and shielding gases, and the joint performance is good.

However, during welding, due to the relatively large friction force between the friction welding head and the battery case and the single clamping direction, there may be a situation where the clamping is not firm enough, and the friction between the friction welding head and the battery case causes the battery case to shift, and the welding quality needs to be improved; and after welding is completed, although there is no spatter debris in friction welding, welding debris will still be generated. These debris usually need to be cleaned by a worker holding a cleaning brush by hand, increasing the fatigue strength of the worker.
