In the process of welding, it is not convenient to clean and store the burrs, and they remain on the surface of the battery box. When the fixture is clamped for the second time, it is easy to cause wear on the surface of the battery box. It also needs to be cleaned after the processing is completed, which is very inconvenient. In addition, keyholes will be left after stir friction welding, and the additional filling of the keyholes also increases the processing steps, which will increase more labor and time, making the processing efficiency low.
