ABSTRACT:
Two members10and20are welded together by cutting a groove41having a determined cross-sectional shape using a cutting tool60along the abutted portion between the two members10and20, inserting a filler member30substantially having the same cross-sectional shape to the groove so as to substantially eliminate the gap at the abutted portion, temporarily welding together the projections12, 22and the filler member30, and thereafter, friction stir welding the members10, 20and the filler member30together completely using a rotary tool81.
