<p>PROBLEM TO BE SOLVED: To rotatably keep positioning pins around pin shafts by rotational angle adjusting means, and to set the section of the positioning pins to be of off-centered circular cam section in a positioning device of butted parts to be laser beam welded in which one work 38 is abutted on the positioning pins, the positioning pins are lowered, the other work is abutted on one work. SOLUTION: When the wear or the bend is recognized in positioning pins, the work receiving position can be corrected by rotating the positioning pins by the quantity of correcting the wear or the bend, butted parts can be positioned at a desired position with a simple constitution, and an excellent welded parts can be obtained.</p> |
