Problems solved by technology

[0005] Although laser-arc hybrid welding and twin-wire welding have many advantages, they also have their own limitations: the most commonly used form of twin-wire welding is tandem twin-wire welding, but this method improves the welding melting point. Deposition rate and welding speed, but did not play a role in increasing the depth of penetration. At the same time, the strong interference between the two arcs in twin-wire welding, tha

Description

technical field [0001] The present invention relates to a welding system, more particularly, to a laser-single power source double-wire pulsed arc composite welding system and a method of using the same. Background technique [0002] Laser welding is to radiate a high-intensity laser beam to the metal surface. Through the interaction between the laser and the metal, the metal absorbs the laser and converts it into heat energy. The metal is melted and then cooled and crystallized to form a weld. Laser welding is widely used in the welding of various structural parts due to its advantages of high energy density, fast welding speed, small deformation, large penetration and easy automation. [0003] In the 1970s, W.M.steen of Imperial University in the United Kingdom used arc welding assisted laser welding for the first time, and proposed the concept of laser-arc hybrid welding technology. Since laser arc hybrid welding technology avoids the shortcomings of separate laser weldi...
