Stationary Shoulder FSW

The bits (left) rotate while the shoulder (right) remains motionless, reducing the amount of excess heat generated by friction. This results in less thermal distortion of the pieces.

Characteristics

Without flash during welding process

Low heat inputting and small deformation

Any angle of plate welding can be achieved (such as 90°,180°,202° and so on)

Applications

motor shells, water-cooled plates, battery trays, car wheels, etc

Rail trains, aerospace, new energy auto parts
