Abstract:
A friction stir welding apparatus includes a FSW tool that is held by a housing and welds to-be-welded members to each other by friction stir, and a gradual cooling device that gradually cools a weld site of the to-be-welded members welded by the FSW tool. The gradual cooling device is a contactless heat source that heats the weld site without coming into contact with the weld site. The contactless heat source is a high-frequency heat source.

Claim (Index 13):
A friction stir welding method comprising:\n by a friction stir welding tool that is held by an apparatus main body and welds a plurality of to-be-welded members to each other by friction stir, welding the to-be-welded members to each other; and after the welding, by a gradual cooling device provided to be movable in a welding direction relative to the apparatus main body, gradually cooling a weld site of the to-be-welded members welded by the friction stir welding tool.
