摘要： PROBLEM TO BE SOLVED: To reliably prevent any welding defect in the lap welding of plates by correctly measuring the space between the plates in the lap welding, and performing an adequate welding work based on the result of measurement.
SOLUTION: The vibration generated by a vibration generator 3 is given to non-welded portions of plates W
1 and W
2 by a vibration transmission roller 4, and the vibration given to the plates W
1 and W
2 is detected by a pickup sensor 5. When the vibration given to the non-welded portions of the plates W
1 and W
2 is detected via the plates, the frequency detected according to the space between the plates becomes different, and by utilizing this fact, the space between the plates immediately before the welding is obtained by referring the detected frequency to the correlation between the pre-grasped space between plates and the detected frequency by an analyzing means 6. The pressure to the plates W
1 and W
2 by a press roller 9 is adjusted according to the correct space between the plates immediately before the welding.

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 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 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.
