Dual-wire hybrid welding system and method of welding

摘要

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.

1. A dual-wire hybrid welding system comprising:
a hybrid welding apparatus, the hybrid welding apparatus having a laser and an electric arc welder having a first wire feeding device for feeding a first wire; and a second wire feeding device for feeding a second wire, the second wire feeding device being arranged and disposed to feed the second wire from the electric arc welder side with respect to a weld direction; wherein the laser and the electric arc welder are arranged and disposed to direct energy toward at least two adjacent components along a joint along the weld direction and the first wire being a consumable electrode fed into the joint after the laser along the weld direction to establish a molten pool generated by both the laser and the electric arc welder with the first wire, the electric arc welder and the first wire also forming an arc area, the laser also forming a laser area, and wherein the second wire is fed to the arc area of the molten pool after the first wire along the weld direction to form a common molten pool, the common molten pool including the laser area and the arc area and being operable to provide a full penetration weld to join the at least two adjacent components without cracking the components at a high constant weld speed, the second wire being fed at a rate to reduce heat input into the at least two adjacent components during welding without creating additional arc between the second wire and the at least two adjacent components; wherein the arc area is located a first distance away from the laser area.
