<p><P>PROBLEM TO BE SOLVED: To provide a method and a device for laser beam welding, with which a laser-welded seam can be formed without being so noticeable. <P>SOLUTION: The task is solved by determining the critical energy input per area unit and time unit into the work piece to be welded, above which the noticeable flaw of the welded seam to a degree exceeding a predetermined level occurs on the side away from the laser beam of the work piece that is farthest removed from the laser beam, and that the laser beam is controlled or regulated in such a way that the critical energy input per area unit and time unit is not exceeded. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
