| 摘 要： | 光纤激光器与活性焊接技术相结合可大幅增加焊缝熔深,提高焊接效率。以TiO2、SiO2、Cr2O3、CaF2和NaF五种活性剂为基础,通过均匀配方设计,获得了15组不同成分的复合活性剂配方,针对SUS304不锈钢板进行光纤连续活性激光焊,研究了氟化物和氧化物对熔深和熔宽的影响,从而获得了最佳配方。试验结果表明:在复合活性剂作用下,焊缝的熔深均有明显的增加,当含氟化物较多时,熔深最大达到1.0 mm,深宽比最大可达1.5,与未涂敷活性剂相比,提高了73%。焊缝的显微组织为粗大的柱状晶,中心存在少量等轴晶,焊缝底部存在明显偏析。

| Abstract: | Fiber laser,combined with the welding technology of activating flux,can significantly improve the welding penetration and efficiency.Based on the five activating fluxes of TiO2,SiO2,Cr2O3,CaF2 and NaF,conducted homogeneous experimental design.Obtained 15 groups activating fluxes with different component.SUS304 plate was used for the the fiber laser continuous welding with mixture. Researched the impact of fluoride and oxid on the penetration and weld width.The results showed that:with the use of composite a... |
