摘要：A friction stir welding apparatus includes: a rotating shaft, on which a thread for
friction stirring is formed; and a drive unit rotatably supporting the rotating shaft. Arotating shoulder configured to rotate together with the rotating shaft to generatefrictional heat between the rotating shoulder and back surfaces of workpieces is fixed toa distal end of the rotating shaft. The rotating shoulder is pushed against the backsurfaces of the workpieces by a pushing mechanism. A stationary shoulder penetrated bythe rotating shaft and configured to hold the workpieces in a sandwiching mannertogether with the rotating shoulder is non-rotatably mounted to the drive unit or amember connected to the drive unit.
