Problems solved by technology

[0002] Existing welding equipment usually uses single-wire welding. In order to ensure that the welding torch is welded in the bead area during the welding process, the welder must observe the state of the welding torch at all times, and adjust the welding parameters online in time during the fixed-point trial teaching program to control the offset error of the welding torch. The operation of the welding process is cumbersome, the workload of the workers is heavy, and the work efficiency is low

Abstract

The invention discloses a laser double-wire welding technology for an aluminum alloy vehicle body part. The laser double-wire welding technology comprises the steps as follows: 1), performing profile assembly; 2), establishing a laser welding tracking program in a welder control system; 3), establishing a double-wire welding technology program in the welder control system; and 4), starting a welder to complete welding. According to the laser double-wire welding technology for the aluminum alloy vehicle body part, a laser welding tracking template is established, and manual welding bead tracking is replaced by laser tracking, so that when the actual welding joint position detected by a laser tracking system and the simulated theoretic welding joint position have deviation, an operator can directly perform on-line compensation according to a deviation value provided by the system, a welding gun is restored to the right position, the operation is simple, further, error operation is not generated easily, the problems that labor intensity for welding gun state observation during manual welding bead tracking is large, operation for on-line welding parameter correction is complicated, operation mistake is easy to generate and the like are solved, and the work efficiency can be greatly improved; and moreover, double-wire welding is adopted, the welding efficiency of the double-wire welding is higher than that of single-wire welding, simultaneously, the welding joint penetration depth is large, and the welding quality is better.
