Laser-consumable electrode arc coaxial combination device

Abstract

Disclosed is a laser-consumable electrode arc coaxial combination device. The problem that a conventional laser-arc hybrid welding device is single in hybrid welding coupling mode and welding mode andpoor in welding effect is solved. The laser-consumable electrode arc coaxial combination device comprises a laser beam splitting system and an arc welding device. The laser beam splitting system comprises a beam splitting reflector, a reflector set, a combined lens and a convex lens. The arc welding device comprises an arc welding gun body, a welding wire and a contact tube. The combined lens comprises a focusing lens portion and a plane reflector portion. Incident laser beams pass through the beam splitting reflector and the reflector set in sequence and then irradiate the combined lens. Thewelding wire and the incident laser beams are coaxially arranged. After the incident laser beams are focused through the focusing lens portion of the combined lens, the incident laser beams and electric arcs generated on the welding wire act on a workpiece to be processed together, or after the incident laser beams are focused through the plane reflector portion of the combined lens and the convex lens, the incident laser beams and the electric arcs generated on the welding wire act on the workpiece to be processed together. The laser-consumable electrode arc coaxial combination device has the advantages of being simple in structure, convenient to assemble, reliable in motion and the like.

Description

technical field [0001] The invention relates to the technical field of laser-arc hybrid welding, in particular to a laser-melting arc coaxial composite device. Background technique [0002] Laser welding has been widely used in shipbuilding, automobile, aerospace, petrochemical, electric power, metallurgy, light industry and other fields, and is considered to be one of the most promising welding methods in the 21st century. , The bridging of the molten pool is poor, so laser welding has high requirements for the preparation work before welding and the assembly accuracy of the workpiece, and the adaptability to gaps and wrong sides is poor. This greatly limits the application range of laser welding technology, and based on the characteristics of certain processing materials such as aluminum alloys with high thermal conductivity, low ionization energy, and high reflectivity to lasers, the stability of the laser welding process is poor, which eventually leads to Poor weld form...
