Stationary Shoulder Friction Stir Welding Tool

Stationary Shoulder Friction Stir Welding Tool

SSFSW can reduce the heat input during welding and obtain a uniform thermal gradient in the thickness direction, thereby improving the surface quality of the joint. It is outstanding for its no thinning after welding.
INQUIRY


Stationary shoulder friction stir welding (SSFSW) is a new friction stir welding technology. Through using specific shape of stationary shoulder, SSFSW can solve any angle of plate welding problem (such as T-type weld). In the structure of SSFSW tool, the shoulder is separated from the pin. When welding, the pin rotates alone, and the shoulder slides relatively on the surface of the material. Compared with the traditional friction stir welding process, the stationary shoulder friction stir welding can reduce the heat input during welding and obtain a uniform thermal gradient in the thickness direction, thereby improving the surface quality of the joint. The stationary shoulder friction stir process is suitable for welding aluminum alloy thick plates, fillet welds, titanium alloys and other materials with low heat transfer rates.

AEE has researched the plate welding technology of many kinds of angle, such as 90°, 180°, 202° and so on.
