Abstract

The invention relates to the technical field of a welding device, in particular to a laser composite welding joint device, which comprises a box body, a composite welding joint, a combined plate, a big gear ring, a sleeve, a small gear and an electric motor. The composite welding joint consists of a laser welding torch and an arc torch. The electric motor drives the big gear ring to rotate through the small gear and simultaneously the sleeve tightly fixed with the big gear ring concentrically rotates together. The combined plate is fixedly connected with the hollow sleeve. The laser welding torch and the arc torch are arranged on the combined plate. The laser welding torch is arranged on a central shaft of the sleeve; consequently during a rotating process, the arc torch enwinds rotates at a 360 degrees around the laser beam of the laser welding torch. The rotating speed and the rotating angle of the composite joint can be controlled through controlling the running of the electric motor to lead the composite joint to be able to adopt the welding on a curve welding line of different curvatures or curvature changes.

Description

Technical field: [0001] The invention relates to the technical field of welding equipment, in particular to a laser hybrid welding head device. Background technique: [0002] In petrochemical, aerospace, military, automobile manufacturing and other fields, the welding of closed or non-closed curve welds on pipes, shells, automobile bodies and other parts is often formed by tailor welding of multiple short welds. Laser arc hybrid welding is a welding technology with fast welding speed, small deformation, less thermal damage to materials and high welding quality. For thin-walled workpieces that are easily deformed, especially when the materials are heat-sensitive materials such as aluminum alloys and titanium alloy sheets, laser arc hybrid welding is a better choice. When performing laser arc hybrid welding, the laser torch travels along the weld seam, and the arc torch is located in the tangential direction of the weld seam trajectory. Therefore, when welding curves, the ar...
