Laser-arc hybrid welding

This invention is a laser-arc hybrid welding process that uses a specially shaped electrode made of filler metal. Unlike conventional laser-arc welding processes, the coaxial arrangement of the individual processes results in a deeper penetration depth with increased process speed and improved inert gas efficacy. In addition, workpieces can be welded regardless of orientation and in forced position welding, because a change of direction does not result in any changes in the arrangement of the arc-electrode-laser beam.
