Manufacturing Process
Friction stir welding utilizes frictional heat as the welding heat source.
The welding process is completed by a special form of stirring head with a probe and shaft shoulder, as shown in the attached figure.
First, rotate the stirring head at high speed and insert the probe into the seam between the workpiece to be welded. Friction rapidly generates heat, and the metal temperature around the probe increases, forming a thermoplastic metal layer. The probe moves down to make the shoulder of the shaft closely contact the working surface, which is close to the surface of the workpiece. When the stirring head moves along the seam of the workpiece, the thermoplastic metal in front of it continuously flows towards the back, and through mutual diffusion and recrystallization, the workpiece is firmly bonded together to form a weld.
