It is difficult to match phases at the particular position of a rotation side and a fixed side using a conventional friction welding machine. Because the rotating spindle does not control the exact stop position. Development of positioning control friction welding meets to be solved difficulties as stop at the specified position during duration of braking. This positioning control friction welding was installed servo motor positioning without hydraulic brake system. Characteristic flash formation is different from ordinary friction welding. Severe metal flow was observed at the vicinity of weld interface in case of positioning control. The sever plastic metal flow was caused in brake stage, and the amount of twist angle was depended on rotation speed and stopping period. Friction and forge pressure effect little on the amount of twist angle.
