摘要： PROBLEM TO BE SOLVED: To solve the problem of a defect in blow holes generated by the ionization of nitrogen in the air even in the case remote welding is performed using a laser beam having a long focus. SOLUTION: A laser beam 7 introduced from a laser oscillator 3 is emitted to the surface of the part to be welded by a scanning means 5. In this case, the laser beam 7 is branched into the first branched beam 8 and the second branched beam 9, and further, the first branched beam 8 and the second branched beam 9 are condensed on the same emitting position, and are emitted. As the penetration quantity required for welding is secured, the energy density of the laser beam passing through the atmosphere in the upper part of a molten pond 13 is reduced, so as to suppress the electrolytic dissociation of nitrogen.
