Zusammenfassung:A system and method is provided where a coated work piece is welded at high speeds with minimal porosity and spatter. The coating on the work piece is removed or ablated by a high energy heat source prior to being welded in a welding operation, such that high welding speeds are attained. The high energy heat source is positioned upstream of the welding operation to vaporize any surface coatings on a work piece.
