Everyone may have heard of Friction Stir Welding (FSW), which 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 and is used for some high-end welding, aerospace Structural parts and manufacturing industries have basically used this welding technology. Now, after the emergence of the new friction stir welding technology, several subsidiary technologies have appeared, which are used in many fields.

It is widely used in various welding technologies, especially the overall structural parts of aircraft, and the study of the law of friction, stress and deformation. It has a wide range of applications in ships, aerospace and aviation. The processing process is relatively special. Basically, this welding technology is used for the storage box of the welding seam, which greatly reduces the heat loss of the welding seam and improves the thermal efficiency. Friction stir welding is very suitable for the current aerospace field, some aluminum alloy profiles. , Often requires better welding technology, strength coefficient, in the welding process, in order to avoid this defect, it is also necessary to meet the requirements of material processing, welding technology can learn from each other.
