Abstract

A dual-wire hybrid welding system (10) includes a hybrid welding apparatus (20) having laser, electric arc welder (40) and second wire feeding device (50). Electric arc welder (40) includes first wire feeding device (42) for feeding first wire (44). Second wire feeding device (50) is arranged and disposed to feed a second wire (52) to electric arc welder (40). Laser (30) and electric arc welder (40) are arranged and disposed to direct energy toward at least two adjacent components (70) along a joint and first wire (44) is a consumable electrode fed into joint to establish molten pool generated by both laser (30) and arc welder (40) with first wire (44). Second wire (52) is fed to molten pool to form a common molten pool (60). Common molten pool (60) is operable to provide a full penetration weld (92) with less total heat input to join the at least two adjacent components (70) without cracking the components (70) at a high constant weld speed.
