Abstract
An objective of the present invention is to provide a friction stir welding device with which the temperature in the proximity of a weld part on a member to be welded can be intermittently measured by enabling the temperature of a plurality of sites in a rotary tool () used for friction stir welding to be ascertained in real-time when welding. This rotary tool () for a friction stir welding device comprises: a hollow channel () that extends from the upper end of a shoulder part () to the proximity of the lower end of a probe (), and that is on substantially the same axis as the axis of rotation of the shoulder part (); and a hollow, outer periphery channel () that is apart from the axis of rotation of the shoulder part () in the radial direction and in proximity of the outer periphery of the shoulder part (), and that extends from the upper end of the shoulder part to the proximity of the lower end thereof. A temperature measurement element () is respectively disposed in the proximity of the lower end of the hollow channel and of the outer periphery channel.
