Laser twin-electric arc compound welding system

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 optimaldistance 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...
