| 摘 要： | 针对2A14铝合金同时进行了激光-MIG复合焊和激光-MIG复合填丝焊试验，对比分析了激光功率、离焦量、焊接速度、焊接电流、光丝间距、填丝速度等工艺参数对两种焊接方法焊缝成形的影响规律.结果表明，铝合金激光-MIG复合填丝焊方法切实可行，工艺适应性良好，与铝合金激光-MIG复合焊相比，均能在较宽的工艺参数范围内实现良好的焊缝成形；相同试验参数条件下，铝合金激光-MIG复合填丝焊的焊缝成形特征与激光-MIG复合焊基本相同，但其熔敷速度明显大于激光-MIG复合焊，焊缝余高明显增加.

| Abstract: | The effect of main parameters on the weld appearance of 2A14 aluminum alloy was investigated by using a laser-MIG hybrid welding process with filler wire, including the laser power, defocus distance, welding speed, welding current, laser-arc distance and wire filling speed. The results were also compared to those with conventional laser-MIG hybrid welding process. It was found that the laser-MIG hybrid welding process with filler wire was feasible and it could achieve good weld appearance in a wide range of process parameters. Compared to the conventional laser-MIG hybrid welding process, during this new welding process, the weld appearance was similar, but deposition rate and reinforcement were biqger than the laser-MIG hybrid welding, with the same parameters. |
