PROBLEM TO BE SOLVED: To perform friction welding by stably fixing a long size and large structure part like a vehicle. SOLUTION: Rollers 7, 7 for pressing down works 2, 2 are arranged in the vicinity of a rotary tool 1, and a roller 8 is arranged on the opposite side to the rollers 7, 7 to support the works 2, 2. These three parties are moved synchronously to perform the friction welding. The fixing jig 7 of the work, which jig is equipped with a rotary mechanism, is moved automatically in the up-down direction following the deformation of the work 2. Consequently, even when the work has been deformed, the fixing jig 7 is not detached from the work 2, a defect can be prevented and high reliability welding can be performed. |
