れている。In this friction stir welding method, structural materials are solid-phase joined to each other, and a rotor (1) as shown in FIG.
Is used. In this rotor (1), a pin-shaped probe (3) smaller in diameter than the cylindrical rotor body (2) is coaxially and integrally protruded from a shaft end of the cylindrical rotor body (2). It is made of hard and heat-resistant material such as steel. Further, predetermined irregularities are formed on the peripheral surface of the probe (3) so that the substrate can be effectively friction-stirred.

The portion (8) is brought into contact with the pressing state, and the contact portion is softened and plasticized by the frictional heat. Then, the rotor (1) is further pressed against the workpieces (6) and (7), and the pin-shaped probe (3) is inserted in the thickness direction of the workpieces (6) and (7). The flat annular shoulder surface (4) at the tip of (2) is brought into contact with the workpieces (6) and (7) in a pressed state. Then, while maintaining the state, the rotor (1)
Is moved along the butting boundary (8) of the workpieces (6) and (7). At the butt boundary where the rotor (1) passes, the surrounding material is softened and stirred by the frictional heat generated by the rotation of the rotor (1), and the cylindrical rotor body (2).
The plastic flow is performed so as to fill the passage groove of the pin-shaped probe (3) while the scattering is restricted by the shoulder surface (4), and then the heat is rapidly lost to be cooled and solidified. Thus, the softening, close contact deformation, stirring, and cooling and solidification of the material at the butting portion (8) are sequentially repeated with the movement of the rotor (1),
The works (6) and (7) are integrated with each other at the butting portion (8) and are sequentially joined.

用いられなかった。However, in the above-described friction stir welding method, in the case of a T-joint type in which fillet welding is performed by welding, a rotor surrounded by a right-angled wall is provided at a corner portion. Is very difficult in practice, and fillet welding by friction stir welding is considered to be difficult. Therefore, the friction stir welding has heretofore been performed for both works (6).
