[0002] Traditional motor housings are assembled with rubber seals to achieve a sealing effect. However, in actual use, as the rubber seals age over time, the risk of product seal failure increases. As the demand for product seal life increases, friction stir welding technology has been further promoted in the field of motor and electronic control.

[0003] As a solid-phase connection technology, friction stir welding has the characteristics of low stress, small deformation, and green and pollution-free. Friction stir welding is a welding method that uses friction heat and plastic deformation heat as welding heat sources. The friction stir welding process is that a stirring needle of a cylinder or other shape (such as a threaded cylinder) is inserted into the joint of the workpiece, and the high-speed rotation of the welding head causes it to rub against the welding workpiece material, thereby increasing the temperature of the material at the connection part and plasticizing it, eventually forming a weld.
