| 摘 要： | 通过对普通铁粉焊条药皮成分进行调整,并加入稀土添加剂研制出了一种新型含稀土高效铁粉焊条.对试件冲击断口的扫描电镜分析,采用IA3001型图像分析仪对焊缝金属夹杂物分析,以及通过低温冲击试验,证实了适量的稀土可起到细化晶粒,净化焊缝的作用.所研制的稀土高效铁粉焊条工艺性能良好,焊缝金属低温韧性好,可用于重要结构的焊接.

| Abstract: | A new type of high efficiency Fe powder covered electrode contented rare-earth was researched.By analysis of fracture surface and metallic impurity in weld metal and impact charpy test in low temperature, it was confirmed that proper rare-earth can fined the crystalline grain and purified the weld metal. The covered electrode can be used to weld the important structure and has good technological properties. |
