基于钍基熔盐堆核能容器制造项目，采用钨极氩弧焊的焊接方法对纯镍N02201以及N10003哈氏合金进行焊接工艺试验研究。采用无损检测、力学性能检测、宏观金相试验方法验证焊接接头的力学性能与组织特性。同时探究了纯镍N02201与哈氏合金N10003焊接时的质量控制措施，制定了适用于纯镍与哈氏合金焊接的理想焊接工艺。结果表明：焊接时需严格控制焊接热输入及层间温度，过大的增加焊接电流不能有效改善液态金属的流动性，相反会增大焊缝出现热裂纹的概率。收弧处需采用衰减电流以避免弧坑裂纹的产生。焊接接头微观组织为奥氏体+少量铁素体组成，焊缝中心晶粒呈树枝状由熔合区向焊缝中心生长，N02201侧熔合区有少量碳化物析出，N10003一侧熔合线分界较为明显。接头无焊接缺陷产生，各项性能均满足相关标准要求。
Based on the thori-based molten salt reactor nuclear energy vessel manufacturing project, the welding process of pure nickel N02201 and N10003 Hasloy alloys was studied by using TIG. Nondestructive testing, mechanical property testing and macroscopic metallographic testing were used to verify the mechanical properties and microstructure of welded joints. At the same time, the quality control measures of pure nickel N10003 and Hastelloy N10003 welding are discussed. An ideal welding process suitable for the welding of pure nickel and Hastelloy alloy was developed. The result shows that: During welding, welding heat input and interlayer temperature should be strictly controlled. Excessive increase of welding current cannot effectively improve the fluidity of liquid metal, on the contrary, it will increase the probability of hot cracks in the weld. Attenuating current should be used to avoid arc pit crack. The microstructure of welded joint is composed of austenite and a small amount of ferrite, The weld center grain grows dendritically from the fusion zone to the weld center, A small number of carbides precipitated in the fusion zone on N02201 side, and the boundary of the fusion line on N10003 side was obvious. no defects appeared in joints; All the properties meet the relevant standards.
