Everyone may have heard of friction stir welding technology. This technology was officially launched in 1991. As soon as it appeared, it attracted the attention of the world. This welding technology is a relatively mature process, used for some high-end welding, aerospace structural parts, manufacturing.

Friction stir welding is widely used in various welding technologies, especially for the overall structural parts of aircraft, as well as the study of the law of friction stress and deformation. The storage box basically uses this welding technology, which greatly reduces the heat loss of the welding seam and improves the thermal efficiency.

Through friction between the welding head and the workpiece, more heat is generated. In the process, it is necessary to overcome various deficiencies, such as resistance heat, plasma arc, and induction heat, to avoid various defects. On the laser and auxiliary system, after rotating friction, a relatively firm joint is finally formed, and the whole welding process is completed. During this process, the loss of the stirring head can also be reduced and the welding efficiency can be improved. This technology greatly widens the welding field, reduces the wear of the stirring head, and improves the service life.
