<P>PROBLEM TO BE SOLVED: To reduce the deformation of members to be welded caused by frictional heat which is generated in friction stir welding and load from a tool. <P>SOLUTION: A butt part W1 where the member 10 to be welded is superposed on the member 20 to be welded, is welded by friction stir welding. A thin walled part 12 is provided in the vicinity of the friction stir welding part FSW1. By the thin walled part 12, the transfer 12 of the frictional heat generated upon friction stir welding and the load from a welding tool to the whole member 10 to be welded is suppressed and the amount of generation of deformation on the member 10 to be welded is reduced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
