Abstract

PURPOSE:To improve productivity by preheating the part on a weld line by a preheating beam formed of a part of a laser beam for welding then executing welding. CONSTITUTION:A part of a laser beam 11 is taken out as a laser beam 12 for preheating by a semitransparent mirror 13 and is irradiated with a blurred focus F on the weld line of base metals 16 by using a mirror 14 and a lens 15. The beam 12 burns or evaporates stains 17 such as oil on the surface of the metals 16 and preheats the base metals. The beam 11 is focused F by a lens 18 onto the weld line of the base metals 16, by which welding on the weld line cleaned up and preheated by the preheating beam 12 is executed. The smoke, etc. 19 generated by the beam 12 is blown off by using an inert gas 21 from a nozzle 20. The welding is accomplished with less defects by the above-mentioned method. The number of stages is thus reduced and productivity is improved.
