FRICTION STIR WELDING APPARATUS

摘要

In a friction stir welding apparatus that can control a penetrating position of a probe with respect to a processing target member to an optimum position at a time of friction stir welding by detecting a wear volume and a tip position of the probe, as a drive mechanism moves down a holder having a coefficient of thermal expansion larger than that of the probe and holding the probe, a detector can freely detect a length of a member including the holder and the probe, and a probe detection mechanism can freely detect a tip length, which is the length of the member of only the probe.

1. A friction stir welding apparatus comprising:
a mounting member on which a processing target member is mounted; a welding tool having a probe, a holder having a coefficient of thermal expansion larger than that of the probe and holding the probe detachably, a drive mechanism that can drive the holder holding the probe to freely move the probe vertically with respect to a processing target side surface of the processing target member and can freely rotate with respect to the processing target member, and a detector that can freely detect a length of a member including the holder and the probe as the drive mechanism moves the holder holding the probe downward; a movement mechanism having an arm to which a fitting jig fitted with the welding tool is fixed so as to be able to freely move the welding tool with respect to the processing target member by moving the arm; and a probe detection mechanism that can freely detect a tip length, which is a length of a member of only the probe, as the drive mechanism moves the holder holding the probe downward.
