  • Patent number: 5168141
    Abstract: To produce precision laser weld joints at weld sites on a workpiece, a TV camera views each weld site through the laser beam optics, and the video output is stored as pixel data in a frame grabber memory. A computer processes the pixel data in accordance with an algorithm to locate the position of the optimum weld point for the imaged weld site relative to the laser beam centerline in the camera field of view and then indexes a X-Y positioning table to fine position the workpiece with the located optimum weld point precisely aligned with the laser beam centerline.
