Abstract
A method for butt welding of flat metal blanks in a welding machine, where two metal blanks are placed on a conveyor unit by feed devices and secured. Two edges of two metal blanks to be welded together are placed together to form a butt joint with the smallest possible gap and then welded together using a welding laser. The gap width is measured and controlled using the measured values from the welding process. The gap width is measured using a reflected-light method and the true gap width via the transmitted light method in such a way that the missing area and the missing volume in the gap can be estimated accurately.
