摘要： A continuous welding method and device for a hybrid welding, a welded finished product and a train body. The method comprises: performing hybrid welding on a groove of a welding piece by coupling a laser and a variable polarity arc; wherein the defocusing distance of the laser is not less than a Rayleigh length of the laser. According to the method of the present disclosure, the power density of the laser on the surface of the welding piece is effectively reduced and the height-width-ratio of the weld seam is decreased, the diameter of the welding melted pore is increased, the voids caused by the collapse of the small pore in the welding melted pore can be effectively reduced, thereby solving the problem that the weld porosity is difficult to escape in the prior art, and reducing the generation of the pores, effectively improving welding stability and reliability, and improving the mechanical properties of the weld seams.

摘要： 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.

摘要： A laser-arc hybrid welding apparatus (1) used for dissimilar material welding includes: a laser-beam irradiation device constituted of a laser oscillator (60) and a laser torch (40); and an arc welding device constituted of a welding power supply (30) and a welding torch (10). The arc welding device changes an arc output (a welding current) at a frequency between a frequency f1 and a frequency f2. At the first frequency f1, an output change in a welding progressing direction occurs in a cycle of 12 mm when welding is performed at a prescribed welding speed. At the second frequency f2, the output change in the welding progressing direction occurs in a cycle of 2 mm when welding is performed at the prescribed welding speed. The welding speed is from 0.8 m/min to 2.0 m/min.
