摘要
In a double-acting friction stir spot welding device (10A) or a double-acting friction stir spot welding method according to the present disclosure, a pin member (11) and a cylindrical shoulder member (12) that rotates around the axis of the pin member (11) are used as rotary tools, and a clamp member 13 that has a cylindrical shape positioned so as to surround the outside of the shoulder member (12) and is configured to press a workpiece (60) from an obverse surface (60a) with an annular pressing surface (13a) of the distal end is used as a holding jig. The clamp member (13) has an inclined surface (13b) that is adjacent to the inner edge portion of the pressing surface (13a) and inclined so as to reduce the inner diameter of the clamp member (13) toward the back side as viewed from the pressing surface (13a).
