Description of the Related Art Friction stir welding is performed by abutting two members to be welded each having a projection (projection) at an end, and inserting a rotary tool from the projection side. This is to compensate for the thinning in the case where there is a gap between the two members. After the joining, if the convex portion is unnecessary, the convex portion is removed by cutting, and the outer surface of the member is smoothed. This is disclosed in JP-A-09-309164 (EP0797043A2).

The small diameter portion enters the joining portion, and the boundary between the large diameter portion and the small diameter portion contacts the member to be joined. The cutter protrudes toward the small diameter portion from the boundary. This cutter is considered to cut burrs generated by friction stir welding. This is disclosed in JP-A-10-71477 (US Pat.
94835). In some cases, a rotary tool is separated from a cutter, and an end mill is used as the cutter. This is disclosed in JP-A-10-175089.

If the convex side is to be the outer surface of the structure, it is necessary to remove the convex by cutting. Therefore, it is conceivable to attach a cutter to the rotating tool and cut off unnecessary protrusions and burrs while joining. An object of the present invention is to provide a method for obtaining a good structure.
