<p>PROBLEM TO BE SOLVED: To solve such problems that extra plates are uneconomically used when two plates are matched or overlayed and a laser welding is done, and also a jig to save plates can not be used due to plate depositing to a jig. SOLUTION: In order to solve the problem, there is disposed a rotary jig 24 between one support 17 and the other support 20, arranged stoper sides 28, 29 for positioning the plates in this rotary jig 24 and formed a recessed groove 31 for preventing the depositing. By turning this rotary jig 24 sequentially, there are performed the positioning of one plate 18 and the other plate 21, and then the stepwise actuation of conformity of the recessed groove 31, etc., is carried out sequentially.</p> |
