Abstract
A laser welding apparatus and process is provided for edge welding sheets of metal to one another. The laser welding apparatus includes aligners to advance the edges to be welded into the laser beam. The apparatus includes first and second laser welders. The first laser welder is operative to eliminate the edge discontinuities and to effect an initial attachment of the edges to one another. The second laser welder provides a larger and stronger weld bead. The process includes first aligning the edges, second removing discontinuities therefrom and third laser welding the edges. The discontinuities preferably are removed by a laser apparatus with a rotating lens.
