摘要
作为耐硫化氢腐蚀的国产12Cr2AlMoV钢,当采用与其匹配的R317焊条焊接时,为防止焊接裂纹,焊前应预热;为抑制“熔合区”产生“铁素体带”,焊后需高温回火,通过可焊性试验以及焊接工艺评定,实验出了该钢最佳焊接热处理规范。
Cr2AlMoV stell is domestic resistant H2S corrosion stell.For this material matching filler matal is R317 electrode.Preheat should be applied for preventing weld-crack and high temperature tempering as PWHT for restraining Ferritic Zone of HAZ.Through welding test and welding procedure specification.We found the available weld procedure and heat treament procedure.
