Abstract
A friction stir welding tool includes a probe having a front end surface and an outer circumferential surface. The probe has, formed therein, outer circumferential recesses extending to the front end surface along a rotation axis. The friction stir welding tool rotates the probe about the rotation axis and embeds the probe inside a workpiece during rotation of the probe to thereby weld the workpiece. The width of the outer circumferential recesses is increased toward a front end of the probe.
