Abstract (en)
[origin: WO2021190705A1] The invention relates to a method for generating a camera image that is used to derive a welding contour along which an assembly (1) is to be welded in an image processing-supported laser transmission welding method. The method is characterized in that the transparent component (2) of the assembly (1) is illuminated from a side facing away from the camera (5). The invention also relates to a device which is suitable for carrying out the method, an illuminating device thereof having at least one light source (6) that is arranged in a workpiece holder (4), in which the assembly (1) to be welded is received in a receiving region (4.1), and is oriented towards the receiving region (4.1).
