1. A double-action friction stir joining system, comprising:
a double-action friction stir joining device;
a cleaning mechanism having a dressing member;
a robot; and
a control device,
wherein the double-action friction stir joining device includes:
a pin member formed in a cylindrical shape and configured to be rotatable on an axis and reciprocatable in a direction along the axis;
a shoulder member formed in a cylindrical shape, into which the pin member is inserted, and configured to be rotatable on the axis and reciprocatable in a direction along the axis;
a first rotary driver configured to rotate the pin member and the shoulder member on the axis, respectively; and
a tool driver configured to reciprocate the pin member and the shoulder member along the axis, respectively,
wherein the control device is adapted to:
(A) operate the tool driver so that the pin member is thrusted into the shoulder member;
(B) operate the first rotary driver so that the shoulder member rotates; and
(C) operate the robot so that the robot holds the double-action friction stir joining device and the dressing member contacts an inner circumferential surface of the shoulder member, and
wherein the control device operates the tool driver in (A) during a cleaning process so that:
(A1) a tip-end face of the pin member is moved to a first position set in advance; and
(A2) the tip-end face of the pin member is moved to a second position set in advance, after (A1), at a larger speed than in (A1).
