    摘要
  • 摘要: 为验证激光对高压干法水下MIG焊电弧稳定性和熔滴过渡控制的影响，搭建了位于高压焊试验舱内的激光增强MIG焊接试验系统，并进行了不同环境压力下激光增强前后的电弧稳定性和熔滴过渡状态对比分析.结果表明，一定功率密度脉冲激光的辅助作用可以克服水下环境压力对熔滴过渡和焊接过程稳定性的负面影响，可以通过脉冲激光控制熔滴尺寸，并且实现熔滴过渡频率与脉冲激光频率保持一致，稳定了焊接电弧，从而提高水下MIG焊过程的稳定性.
    Abstract: To verify the effect of laser on arc stability and metal transfer control in hyperbaric underwater MIG welding, the related experiment system was built in hyperbaric welding test chamber, and contrastive study on arc stability and metal transfer state with and without laser enhanced was conducted in different ambient pressure. The results show that the application of a certain power density of pulsed laser could offset the negative effect of underwater ambient pressure on metal transfer and welding processing stability, the size of droplet could be controlled by pulsed laser and the metal transfer frequency could be equal to the frequency of pulsed laser, the arc stability could also be improved, thus the welding processing stability could be improved.
