摘要
对４２ＣｒＭｏ与Ｓｔ４５．８对接接头的各项性能指标进行了测定和研究。根据电厂现场安装的特点，提出了在４２ＣｒＭｏ坡口侧堆焊过渡层现场焊接工艺。
All performance indices of 42CrMo and St45.8 steel butt joint were test and studied in detail. In accordance with characteristics of site installation in steam power plant, the welding technology of bevel side bead welding intermedium in downcomer of 42CrMo steel was proposed which could solve the problem of site welding of the weld tine.
