摘要： PURPOSE:To constrain the generation amt. itself of a resin gas and its injection onto the surface and to extend the gap of the maintenance of a dust collection route by intermittently projecting the laser light focusing on the surface of a laminated resin material on the laminated resin material under moving it along a cutting locus. CONSTITUTION:A laser light R is intermittently projected by an oscillation output on a laminated resin material W under moving a laser machining head 1 at the specified speed. The surface skin member Wa of the laminated resin material W is then melted discontinuously because the laser light R is projected by being stopped at one point and the laser light R is projected in its diffused state on the foaming member Wb of the inner part. So the part close to the core member Wc of the lowest layer is continuously melted. The resin gas G generated with the foaming member Wb being melted at this melting time is difficult to leak to the outside because the molten opening part of the surface skin part Wa is hardly opened like a sawing machine seam, so one part is injected to the surface but the majority is filled up in the cavity after burning of the foaming member Wb and stuck to the inner wall of the cavity after cooling.

摘要： PROBLEM TO BE SOLVED: To provide a laser welding quality inspection method and a device therefor capable of performing the quality inspection of laser welding at high precision with a simple constitution. SOLUTION: In laser lap welding, a light receiving apparatus 4 receives laser reflected light 1b from a boundary wall face between a keyhole 6 formed at the laser irradiation position 5 of the metal 2 to be welded and a molten pool formed on the backside in the welding progression direction of the keyhole 6, i.e., the tip wall face 7 of the molten pool. The change in the intensity of the laser reflected light 1b from the tip wall face 7 of the molten pool by the back and forth movement thereof expresses whether the welding quality is good or bad at high precision. The light receiving apparatus 4 detects the change in the intensity of the laser reflected light 1b, and a processor 11 analyzes the same and determines whether the welding quality is good or bad. The light receiving apparatus 4 has a constitution where light is received from the front slanting upper part of the welding progression direction, and a spectral structure is made needless.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for inspecting the laser welding quality for easily and reliably determining any defective welding or precursory phenomenon, and more correctly inspecting the welding quality. SOLUTION: Images of a place corresponding to the irradiation position of laser beams 1a and a place in a vicinity thereof between members 2a and 2b to be welded are taken in at high speed from the side during the laser lap welding. The distance from the position of a first luminous image corresponding to the laser beam irradiation position to the position of a bridge-like second luminous image formed on the back side of the welding direction in the taken-in image is obtained by an image processor 7. The obtained value is compared with a reference value by a determination circuit 8, and the result is specified as the inspection result of the welding quality. The value for obtaining the inspection result of "Good" by an experiment or the like in advance is selected as the reference value. Both luminous images are brighter than other peripheral portions, and the distance between the luminous images can be easily obtained. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a method and a system for evaluating a quality for evaluating, accurately and in real time, whether the joint with a welding bead is satisfactory or not when two stacked metal plates are irradiated with a laser beam for stack welding. SOLUTION: This method for evaluating the quality relates to the laser beam welding for welding two metal plates by shifting a welding torch 15 irradiating the laser beam along the surface of an upper metal plate 12 stacked on a lower metal plate 10. This method is composed of a detecting process and a judging process. In the detecting process, heat information is detected in at least one side of adjacent portions 42a, 43a on both sides of the fusion portion 41a on the surface of the upper metal plate in the welding. In the judging process, the width of the adjacent portion is obtained on the basis of the detected heat information to judge whether the joint is satisfactory or not by comparing the width with the pre-prepared reference value.
