  • Patent number: 9278407
    Abstract: A dual-wire hybrid welding system includes a hybrid welding apparatus having laser, electric arc welder and second wire feeding device. Electric arc welder includes first wire feeding device for feeding first wire. Second wire feeding device is arranged and disposed to feed a second wire to electric arc welder. Laser and electric arc welder are arranged and disposed to direct energy toward at least two adjacent components along a joint and first wire is a consumable electrode fed into joint to establish molten pool generated by both laser and arc welder with first wire. Second wire is fed to molten pool to form a common molten pool. Common molten pool is operable to provide a full penetration weld with less total heat input to join the at least two adjacent components without cracking the components at a high constant weld speed.

  • Publication number: 20140027414
    Abstract: A hybrid welding system including a hybrid welding apparatus and method of welding are provided. The hybrid welding apparatus includes a laser, an electric arc welder with a non-consumable electrode and a wire feeding device. The electric arc welder provides an electric arc without feeding a welding wire. The wire feeding device is arranged and disposed to feed a wire to a treatment area, which is located between the projections of laser beam and the electric arc. The laser and the electric arc welder are arranged and disposed to direct energy toward at least two adjacent components to form a common molten pool. The wire is fed by the wire feeding device into the common molten pool created by the laser and the electric arc.

  • Patent number: 8546720
    Abstract: A hybrid welding apparatus, and a system and method for welding at least two adjacent components having a large gap of approximately 3.0 millimeters that results in a full-penetration weld is provided. The welding system includes a hybrid welder having a defocused laser beam, an electric arc welder, and at least one bridge piece adjacent to one or more of the at least two adjacent components. The defocused laser beam and the electric arc welder are arranged and disposed to direct energy onto the at least two adjacent components to create a common molten pool operable to provide a full penetration weld to bridge the gap at a high constant weld speed, thereby joining the two adjacent components with a weld.
