Problems solved by technology

[0002] Aluminum / steel dissimilar metals are widely used in the automotive industry. Due to the poor weldability of aluminum and steel, it is difficult to achieve high-quality connection of aluminum / steel dissimilar metals by traditional welding methods. Appropriate welding methods must be used. Compared with the traditional welding process, laser welding has the characteristics of energy concentration, high welding penetration ratio, small welding deformation, fine grain grains of the weld seam formed, and high welding efficiency. It has been widely used, but the conventional single heat source laser welding technology Due to the narrow heating width, it is not conducive to the spreading of the metal, which can no longer meet the requirements of actual production.

Abstract

The invention discloses a double-arc auxiliary laser welding device and method. The device comprises a welding worktable, a horizontal plane moving device, a base, a ring-shaped sliding rail, a TIG welding sliding guide rail, a laser guide rail, a plasma arc welding gun guide rail, a coaxial powder sending device, a TIG welding device, a laser device and a plasma arc welding device, wherein the TIG welding device, the laser device and the plasma arc welding device are located on the same plane. The horizontal plane moving device adjusts the welding worktable to move in the horizontal plane. The ring-shaped sliding guide rail is fixedly arranged on the base. The TIG welding device, the laser device and the plasma arc welding device are connected with the TIG welding sliding guide rail, thelaser guide rail and the plasma arc welding gun guide rail correspondingly. The TIG welding sliding guide rail and the plasma arc welding gun guide rail are arranged on the ring-shaped sliding guide rail. The laser guide rail is fixedly arranged on the ring-shaped sliding guide rail, and the coaxial powder sending device is connected with the plasma arc welding device. By means of the double-arc auxiliary laser welding device, penetration of the back face of a connector can be ensured while the welding speed is increased, the forming attractiveness of a weld joint is achieved while the cleanliness of the weld joint is ensured, and the quality of the weld joint is high.
