<P>PROBLEM TO BE SOLVED: To provide a laser welding apparatus capable of reducing the adverse effect of the fume. <P>SOLUTION: An air injecting nozzle 7 is installed at a laser processing head 3. The injecting direction of air from the air injecting nozzle 7 is set such that the air flows across a laser beam irradiated from the laser processing head 3 while the air flow avoids direct contact with the laser irradiating point P on the workpiece. <P>COPYRIGHT: (C)2008,JPO&INPIT |
