摘要
针对大型水轮机转轮用ＺＧ０Ｃｒｌ３Ｎｉ５Ｍｏ高强马氏体不锈钢的熔化极气体保护焊工艺，研究了活性气体对焊丝 ＨＳ３６７Ｌ和 ＨＳ１３５Ｌ熔敷金属化学成分和力学性能的影响。
The influence of active gas on chemical compositions and mechanical properlies of HS367L (Crl6 - Ni5 - Fe) and HS135L(CrlZ - Ni5 - Fe) martensitic stainless deposited metals were investigated in Ar- rich MAG welding of OCrl3Ni5Mo martensitic stainless steel for hydro - turbine runners.
