<p><P>PROBLEM TO BE SOLVED: To provide a laser beam machining apparatus which can realize high- speed machining to improve work efficiency and, at the same time, can machine even a product having a complicated shape at a low cost. <P>SOLUTION: This laser beam machining apparatus 10 includes a plurality of laser beam oscillation devices 12 and a condensing optical system 18 that focuses laser beams, which has been output from the individual laser oscillation devices 12, independently of each other to a machining face. The condensing optical system 18 is disposed so as to focus the laser beams along a machining line. Laser beams are simultaneously output from the individual laser beam oscillation devices 12, whereby a workpiece 1 can be welded in a very short time. <P>COPYRIGHT: (C)2003,JPO</p> |
