Continuous butt joint welding for sheet metal, esp. vehicular body, panels

摘要

A continuous butt-welding process and device for metal sheets, useful in particular for building car bodies in the car industry by beam welding, allow metal sheets laid on conveyor paths to be precisely joined and welded without the need to accurately align them. For that purpose, a special control of the metal sheets to be welded and seam position sensors are used.
