Beschreibung
Zusammenfassung:	A system and method is provided where a work piece is welded at high speeds with minimal porosity and spatter. In embodiments, the work piece is welded with an arc welding process to create a weld puddle and the weld puddle is irradiated by a energy beam downstream of the arc welding operation, such that high welding speeds are attained. The high energy heat source is positioned downstream of the welding operation to input energy into the weld puddle to change its shape or characteristics to optimize bead shape and/or bead quality.
