ABSTRACT:
The purpose of the present invention is to provide a method that can be easily applied to friction stir welding where the thickness of face plates at one welding portion is different from the thickness of face plates at another welding portion. Three shape members10, 11, 12having two butt joint portions are mounted on a jig15.The face plate14of shape member10is thick and the face plate14of shape member12is thin. The protruded height of projection18is greater at portion B where surface plates14being welded are thin than the protruded height of projection A where surface plates14are thick. The depths for inserting rotary tools to shape members10, 11, 12for friction stir welding are the same. Friction stir welding is facilitated since the size and insertion depth of all the rotary tools being applied can be the same.
