摘要：
The present invention is a friction stir welding machine adapted to perform solid phase welding on a welding portion of materials to be welded, by pressing a welding tool (4) against the welding portion of the materials to be welded while rotating the welding tool (4), and forcing the welding tool (4) to be advanced into a softened portion which is softened by a frictional heat while stirring the softened portion, wherein a coating (50) made of aluminum nitride is formed on at least a region of the welding tool (4) to be in contact with the materials to be welded.
