Abstract

This friction stir pot welding device is provided with: a pin member (11); a shoulder member (12); a rotation driver (57); an advance / retreat driver (53); and a controller (51) that is configured to actuate the advance / retreat driver (53) and the rotation driver (57) so as to cause a tip end of the rotated shoulder member (12) to reach as far as a predetermined first position previously set inside a second member (62) and so that the rotated pin member (11) retreats from a joined section of joined object (60).

Description

technical field [0001] The present invention relates to a friction stir point joining device and its operating method. Background technique [0002] There is known a method of joining dissimilar metal parts by overlapping a first part made of a soft metal and a second part made of a hard metal, and rotating a probe from the side of the first part so that The end thereof is inserted so as to reach directly above the second member, friction stirring is performed, and the first and second members are joined (for example, refer to Patent Document 1). [0003] In the method for joining dissimilar metal parts disclosed in Patent Document 1, a double-action rotary tool is used as a rotary tool in which the probe is independently configured from the shoulder member and can move independently in the axial direction. One component performs friction stir welding of the first and second components. [0004] Patent Document 1: Japanese Patent No. 4937386 [0005] However, in the metho...
