摘要

提出了基于电弧预熔丝的激光焊方法,研究了入射能量对焊丝熔化状态以及焊缝成形的影响,进一步对焊接过程的工艺适应性进行了分析。结果表明,当焊接电流较小时,焊丝能稳定地熔化、填充进熔池中,增大焊接电流有利于增加焊丝前端的熔化长度;增加激光功率对焊丝熔化量无影响。电弧预熔丝激光焊方法可降低焊缝气孔率,对装配间隙具有很好的适应性。

Abstract

The method of laser welding with pre-melted liquid filler by arc is proposed, and the influence of incident energy on the melting state of the filler wire and the weld appearance is studied. The process adaptability of the welding process is further analyzed. The results show that, when the welding current is relatively low, the filler wire can be stably melted and filled into the molten pool, and the increase of the welding current is beneficial to increasing the melting length of the front-end filler wire. The increase of the laser power has no effect on the melting amount of the filler wire. The method of laser welding with pre-melted liquid filler by arc can reduce the porosity of weld and significantly improve the adaptability to assembly clearance.
