Abstract
A hybrid welding from a combination of laser beam welding with gas-shielded welding by electric arc uses at least two electrodes are used. The electrodes can be flooded by a common shielding gas curtain or separately or in groups. The hybrid welding increases the possibility of influencing the welding process and especially provides improved possibilities for automation.
