<p><P>PROBLEM TO BE SOLVED: To provide a laser welding device capable of highly accurately performing welding of an object to be irradiated at high speed with laser irradiation. <P>SOLUTION: The laser welding device has an irradiation head provided with an optical element comprising an image-forming optical group, a prism group and a deflection optical group, whereby a multi-point irradiation of laser is highly accurately performed toward an outer circumferential part of a cylindrical workpiece at high speed and, thereby, two members are bonded. Further, the laser welding device has a support mechanism of the positioning of the workpiece, for the prism group and the deflection optical group and, every time processing, securely supports the work and prevents deviation. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
