摘　　要：鉴于目前工程上基本依赖进口ENiCrMo-10焊材的现状,开展了ENiCrMo-10焊条的国产化研究。结果表明,通过调整药皮中大理石、氟化物及硅酸盐的比例,添加约20%的金属粉,优化熔渣流动性,控制焊缝中S,P,B,Mo,Cr,W等元素的含量,研制的ENiCrMo-10焊条具有优良的平、立焊工艺性,较出色的耐晶间腐蚀、耐点腐蚀及抗裂性能,能够满足工程应用的技术要求。In view of the current situation that the project basically relies on imported ENiCrMo-10 welding materials,the research on the localization of ENiCrMo-10 electrode has been carried out.The results show that by adjusting the proportion of marble,fluoride and silicate in the coating,adding about 20%metal powder,optimizing the fluidity of slag,controlling the content of S,P,B,Mo,Cr,W and other elements in the weld,the ENiCrMo-10 electrode has excellent flat and vertical welding technology,excellent Intergranular corrosion resistance,pitting corrosion resistance and crack resistance,which can meet the requirements of engineering application.
