ABSTRACT:
A cutting tool60cuts along the butted portion between two members10, 20. A filling material30is inserted to the gap40formed by said cutting, and a roller70presses protrusions12and22to crimp said protrusions12and22so as to fix said filling material to position. Next, friction stir welding is performed to the protrusions12, 22and the filling material30using a rotary tool80. In another example, instead of cutting, the filling material can be welded and filled to the gap. In yet another example, cutting can be performed so as to approximate the two members before performing the friction stir welding step.
