发明名称 ROTARY TOOL FOR FRICTION STIRRING-SPOT WELDING AND FRICTION STIRRING-SPOT WELDING METHOD USING THE ROTARY TOOL
摘要 <p>A rotary tool for friction stirring-spot welding and a friction stirring-spot welding method capable of smoothly and repeatedly performing a friction stirring-spot welding operation by effectively relieving or avoiding problems caused by the adhesion of a material invading into clearances between a probe and a shoulder member. The rotary tool (10) for friction stirring-spot welding comprises the rod-like probe (12) formed by stacking a plurality of joined metal members on each other and inserted from one side of the stacked part thereof into the shoulder member while being rotated and the cylindrical shoulder member (14) fitted onto the outer periphery of the probe coaxially with each other and having a shoulder surface brought into contact with the surface thereof on the one side under rotation. The tool (10) is formed in a double-acting structure so that the probe is separated from the shoulder member and the probe and the shoulder member can be axially moved independently of each other. The clearance (22a) between the inner peripheral surface of the shoulder member and the outer peripheral surface of the probe is formed smaller (22a) at the tip side and larger (22b) than the small clearance at the base side.</p>
