Method and device for generating a camera image of a welding seam for an image processing-supported laser transmission welding method

A device for generating a camera image from which a welding contour can be derived along which an assembly, comprising a transparent component transparent to a laser radiation and an absorbing component absorbing the laser radiation, is to be welded in an image processing-assisted laser transmission welding process, wherein the absorbing component has at least one end face which is bounded by at least one edge formed with at least one wall surface of the absorbing component and represents the welding contour, and the transparent component rests on the end face, the device comprising:

• a workpiece holder having a receiving area within which the assembly is fixed,
• a camera having a camera axis directed toward the receiving area, wherein an object plane of the camera lies within the receiving area in which the welding contour of a received assembly is located, and
• an illumination unit having at least one light source emitting an illumination beam, wherein the at least one light source is arranged on or in the workpiece holder and is directed into the receiving area.
