PROBLEM TO BE SOLVED: To provide a friction stirring joining method that causes no holes or recesses after a probe is pulled out, in joining members having parts to be welded in the peripheral direction on the circumferential surface. SOLUTION: The end faces are abutted on each other of the two joining members 1, 2 that consist of an aluminum pipe material having a circular cross section, with a rotating probe 22 inserted into this abutted part. Then, while the part in contact with the probe 22 is softened by frictional heat and stirred, the joining members 1, 2 are rotated so that the abutted part successively passes through the probe 22. When the joining members 1, 2 make one rotation, they are stopped. After that, an abutting member 10 is applied against the joining end W2 in the tangential direction of the seam in this joining end. Then, the probe 22 is moved to the abutting member 10. |
