Abstract
The supporting block for the focusing device of a laser welding apparatus is mounted onto the working surface of the body of the lower tool. The cutting edge of the die set into the body of the lower tool is aligned with the working surface. For a resharpening of the cutting edge the working surface is reground and accordingly also the area, on which the supporting block rests. Conclusively, no readjusting of the focusing device relative to the welding point at the die is necessary.
