| 摘 要： | 采用ERNiCu—7镍基合金焊丝直接在16MnR表面堆焊Monel400合金.分别对钨极气体保护焊(GTAW)和熔化极气体保护焊(GMAW)及其二者组合施焊的堆焊层不同厚度处的化学成分进行分析比较,探讨了焊接过程中异种金属材料之间基本元素的相互稀释及其扩散的趋势和程度,分析了堆焊界面弯曲性能、宏观及微观组织.结果表明,GTAW+脉冲GMAW的组合方法焊接,堆焊层厚度大于2.5mm时,影响堆焊层腐蚀性能的Fe,Ni,Cu等主要元素就能达到ERNiCu—7合金焊丝的标称合金成分要求;侧弯性能测试结果良好;焊接工艺性好,质量稳定可靠,生产效率高.

| Abstract: | Mone1400 alloy was surfaced on 16MnR steel with ERNiCu-7 nickel-base alloy welding wire.Chemical composition of different thickness for surfacing layer by gas tungsten arc welding(GTAW),gas metal arc welding(GMAW)and welding combined GTAW with GMAW was analyzed.The diffusion and dilution of basic elements in different metal materials were researched,and bending performance,macrostructure and microstructure of interface were studied.The results show that erosion resistant performance of surfacing layer is ex... |
