PURPOSE: To obtain a good joining even in the case of being a large gap between butting parts of two members. CONSTITUTION: Cutting is applied along the butting parts of two members 10, 20 with a cutting tool 60. A supplemental material 30 is inserted into a gap 40 generated with the cutting and the projecting parts 12, 22 are pressed with a roller 70, and the supplemental material 30 is fixed by caulking the projecting parts 12, 22. Successively, the friction stirring-joining is applied to the projecting parts 12, 22 and the supplemental material 30 with a rotating tool 80. The supplemental material can be filled up into the gap by welding without cutting or the friction stirring-joining can be applied by approaching two members after cutting. |
