摘要： PROBLEM TO BE SOLVED: To provide a laser welding inspection device which can excellently carry out the evaluation of the welding quality by suppressing the effect of foreign substances to be stuck on a protection glass with a simple configuration. SOLUTION: A first image formation point 15 for a workpiece W is provided between a camera 11 and the workpiece W. The image of the workpiece W is formed on the first image formation point 15 and is picked up by means of the camera 11. Meanwhile, the image for a protection glass 12 is not formed on the first image formation point 15, and is diffused, and is picked up by means of the camera 11. For this reason, the image caused by the dirt on the protection glass 12 is diffused. As a result, in the image picked up by means of the camera 11, the images due to the dirt become few and the images due to the workpiece W become relatively many. Therefore, the accuracy of the evaluation of the quality of the workpiece W can be improved. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for evaluating the quality of laser welding, which method can excellently carry out the evaluation of the quality of laser welding by suppressing the effect of foreign substances to be stuck on a protection glass, and further to provide apparatus therefor. SOLUTION: A subtraction circuit 22 receives, in real-time, the image in welding to be taken by a CCD camera 8, and subtracts the image in power monitoring stored in a memory 21 from the image in welding, and achieves the subtracted reflection light image. The images of foreign substances included in the image in welding and the image in power monitoring are canceled by the subtraction in the subtraction circuit 22. Therefore, the subtracted reflection light image achieved by the subtraction does not include the image of foreign substances. A quality judging device 17 judges the quality of welding using the subtracted reflection light image achieved in the subtraction circuit 22. As described above, the subtracted reflection light image does not include the image of foreign substances. Therefore, the quality judging device 17 can excellently carry out the evaluation of the quality of welding without being affected by the foreign substances to be stuck on the protection glass 15.
