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 7):
The friction stir welding apparatus according to  claim 1 , comprising:\n a tool movement driver that moves the friction stir welding tool along a welding line; a gradual cooling device axial direction movement driver that moves the gradual cooling device toward and away from the weld site; and a gradual cooler driving controller that controls the gradual cooling device axial direction movement driver, wherein the gradual cooler driving controller controls the gradual cooling device axial direction movement driver to drive the gradual cooling device toward the weld site when the friction stir welding tool is moved away from the weld site at end of welding.
