MANUFACTURING METHOD OF BUTT JOINT, BUTT JOINT, MANUFACTURING METHOD OF BENT MEMBER, AND FRICTION STIR JOINING METHOD

摘要

Two joining members (1, 2) different in high temperature deformation resistance are disposed in an abutted manner. The rotational direction of a probe (12) of a joining member (10) is set so as to coincide with a rotational direction R rotating from the joining member (1) having lower high temperature deformation resistance toward the joining member (2) having higher high temperature deformation resistance. Then, the rotating probe (12) is inserted into the abutting portion (3) of the joining members (1, 2). The probe (12) is advance along the abutting portion (3) with the probe (12) inserted in the abutting portion (3) to perform the friction stir joining. As a result, a butt joint having high joining strength can be obtained.
