  • Method and device for the optical assessment of welding quality during welding
    Patent number: 8208135
    Abstract: In laser welding, the welding area is depicted coaxially in relation to the laser beam (3) through the laser optics (4), wherein not only a triangulation line and a grey or color image of the solidified weld is recorded but also the process radiation of the welding process. From these three image elements, an optimum quality assessment of the welding process and of the weld can be made.

  • Method and device for assessing joins of workpieces
    Patent number: 7983470
    Abstract: For assessing the position and quality of joins a combined image of a join including a light line image and a grey value image is taken in the same sensor, but in two different regions of the sensor. The grey value image is evaluated to detect the quality of the join. This allows both the position and the quality of the join to be detected in a simple way.

  • Method and device for evaluation of jointing regions on workpieces
    Patent number: 7577285
    Abstract: A method and apparatus for detecting a joint between workpieces is provided. At least one light line is recorded by the light section method to detect the three-dimensional course of the joint and a grey-level image of the joint is also recorded. The grey-level image is evaluated to assess the quality of the joint.
