Problems solved by technology

[0004] Because laser hybrid welding itself has the advantages of deep penetration, good shape, and excellent weld structure, twin-wire welding also has considerable advantages in high-efficiency and high-speed welding. However, they also have their own limitations: twin-wire welding The most commonly used is the form of tandem twin wire welding, but although this method improves the welding deposition rate and welding speed, it does not play the role of increasing the penetration depth; when laser arc hybrid welding, the two There is a mismatch in the welding speed, and how to control the force between the two arcs will seriously affect the quality of laser arc composite heat source welding

Abstract

The invention discloses a laser twin-electric arc compound welding system. The existing fixture for clamping a welding gun and adjusting the position of the welding gun is utilized to adjust the relative positions of two welding guns and a laser machine head, the welding process is adjusted through controlling the distance between two welding wires, a stable welding process is realized by optimal distance control, and because the combination of two electric arcs and a laser heat source greatly improve the welding efficiency, welding penetration and fusion width are enlarged, and the forming of weld joints is improved.

Description

technical field [0001] The invention relates to a welding system, more specifically, to a laser double-arc composite welding system. Background technique [0002] As a special heat source, laser has its own unique characteristics compared with traditional welding heat sources. After focusing, the laser beam can reach extremely high power density, which can melt or even vaporize metals with high melting point, so it can be used for precision welding of special materials. Due to the concentration of laser beam energy, the input line energy in the welding process is small, so the thermal deformation and welding heat-affected zone are small, so that the welding speed can be appropriately increased, and the production efficiency is greatly improved. In the 1970s, W.M.Steen of the British Imperial University used arc welding to assist laser welding for the first time, and proposed the concept of laser-arc hybrid welding technology. The main idea is to superimpose two heat source...
