摘要
以LF6铝合金为材料,开展了CO2激光-TIG电弧复合焊接工艺试验研究。试验结果表明,与单激光或TIG电弧比较,激光-TIG复合焊接可以提高焊缝熔深,改善焊缝成形,降低气孔和下塌等焊接缺陷。在此基础上,进一步研究了不同工艺参数对焊缝成形的影响,探索了铝合金激光-TIG电弧复合焊接的可行性。
The Al alloy butt-joints were carried out by CO2 laser-TIG arc hybrid welding.The experimental results show that,compared with laser welding or TIG arc welding,the hybrid welding can obtain better weld bead,increase weld penetration,and reduce welding defects of pore and collapse,and so on.Furthermore,the influences of different welding parameters on weld appearance were investigated,which explores the technical feasibility of hybrid welding in Al alloy and lays a good foundation for practical application.
