摘要: 通过与铝合金激光-MIG复合焊方法相对比，主要研究了铝合金激光-MIG复合填丝焊的焊缝成形、熔深稳定性、余高稳定性、焊缝气孔率、激光匙孔特征、等离子体特征. 试验结果表明，在合适的工艺参数条件下，铝合金激光-MIG复合填丝焊焊接过程稳定，焊缝成形良好，额外填入的焊丝可以连续稳定地过渡到熔池中，激光匙孔具有明显的形成、长大、湮灭周期性变化特征；相同工艺参数条件下，铝合金激光-MIG复合填丝焊的焊缝熔深稳定性、余高稳定性与激光-MIG复合焊相当，激光匙孔开口面积约增加15.34%，等离子体+电弧总面积约增加1.95%.

Abstract: Weld appearance, the stabilities of penetration depth, reinforcement as well as porosity, laser keyhole characteristic and plasma characteristic were studied by using a new laser-MIG hybrid welding process with filling wire of aluminum alloy. The results were also compared with those by conventional laser-MIG hybrid welding process. It is found that with the suitable process parameters, this new welding process for aluminum alloy was stable. The extra wire deposited continuously and the keyhole had obvious periodic variations, including formation, growth and annihilation. The final weld bead had fine appearance. Compared to conventional laser-MIG hybrid welding process, during this new welding process the stabilities of penetration depth and reinforcement were similar, while the keyhole opening area had differences of 15.34%, the total area of plasma and arc had differences of 1.95%. -
