Abstract: 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.

Abstract: PROBLEM TO BE SOLVED: To provide a butt laser beam welding method, and a butt laser beam welding equipment capable of obtaining an excellent welded condition by allowing both end faces to form a large space therebetween to be directly irradiated with laser beams while suppressing degradation of the power density of the laser beams on a surface of irradiation even when a large space is present between both the end faces to be butted to each other. SOLUTION: The space set value s is preset according to the size of a space to be formed between both the end faces 1a, 2a when the end faces 1a, 2a of a member to be welded are butted to each other. Elliptical beams 12 in which the major axis length a and the major axis direction of an elliptical section on the surface of irradiation are adjusted so that the beams are condensed on the elliptical section by the surface of irradiation on a butt line 3, the value of the major axis length a of the elliptical section is larger than the space set value s, and a range of irradiation reaches both the end faces 1a, 2a to form a space of the space set value s are scanned along the butt line 3. By directly irradiating both the end faces 1a, 2a with the elliptical beams 12 and reliably melting the end faces, the end faces 1a, 2a are integrally welded in an excellent welded condition.
