摘要
用Ni基R-N_1焊丝作为填充材料,采用小线能量的手工氩弧焊方法可实现离心铸造HP-Nb高温合金炉管与1Cr5Mo钢法兰异质钢的焊接。焊缝组织良好,过渡区狭窄,焊接接头力学性能满足质量要求。
Centrifugally casted HP-Nb superalloy pipe and ICr5Mo steel flange was welded together by manual tungsten -inert - gas arc welding with Ni - based R - N1 wire. The microstructures of the weld and HAZ were fine, and the mechanical properties of the welded joint were identical with that by the ordinary quality.
