| 摘 要： | 研究了船用10CrNi3MoV钢激光-MAG复合焊接头组织和力学性能,并与常规MAG焊接头进行了对比。结果表明,采用激光-MAG复合焊接工艺进行10CrNi3MoV钢焊接是可行的;与常规MAG焊相比,激光-MAG复合焊接头显微硬度明显升高,焊缝中心冲击韧性有一定下降,但仍能满足技术指标要求。为进一步改善焊接接头的综合性能,提出通过焊接材料成分优化,来降低焊缝金属淬硬倾向,提高接头的韧性水平。

| Abstract: | The macrostructure,microstructure,mechanical property of hybrid laser arc weld in 10CrNi3MoV steel was evaluated.Experiments were conducted to compare hybrid laser arc welding(HLAW) to gas metal arc welding(GMAW).The result shows that,hybrid laser arc welding is a suitable process for 10CrNi3MoV steel.Compare to MAG welding process,HLAW welds exhibited much higher hardness and lower impact ductility,and the mechanical property of the HLAW welds meets the qualification.For further improvement of comprehensive mechanical property,approaches such as optimizing welding material component,reducing quench-hardening tendency of the welded joint to improve the joint impact ductility are presented. |
