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 12):
A friction stir welding control device connected to a friction stir welding apparatus which includes 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, a gradual cooling device that gradually cools a weld site of the to-be-welded members welded by the friction stir welding tool, a gradual cooling device welding direction movement driver that is provided to the apparatus main body and moves the gradual cooling device in a welding direction, and a temperature measurement device that measures a welding temperature of the weld site, the friction stir welding control device comprising:\n a target temperature storage that stores a target temperature to be set for the weld site; and a heat amount calculator that calculates an amount of heat to be applied to the weld site based on the target temperature, wherein the heat amount calculator controls the gradual cooling device so that the welding temperature has zero deviation from the target temperature.
