  • Double-action friction-stir joining system and method utilizing a cleaning mechanism
    Patent number: 11938558
    Abstract: A double-action friction stir joining system, which includes a double-action friction stir joining device, a cleaning mechanism having a dressing member, a robot, and a control device. The double-action friction stir joining device includes a first rotary driver configured to rotate a pin member and a shoulder member, and a tool driver configured to reciprocate the pin member and the shoulder member. 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.
