第十章异种钢的焊接异种钢的焊接（成分不均匀、组织不均匀、性能不均匀、应力场分布不均匀）1、异种钢焊接的工艺原则1）方法：均可2）焊材：焊接工艺性能、接头使用性能3）坡口：厚度、熔合比（越小越好）4）工艺参数：稀释率；较小5）热参数：一般按强度等级高、淬硬倾向大的考虑一焊接材料选用1.1、不同铁素体钢的焊接不同强度级别的低碳钢、低合金钢、珠光体耐热钢之间的异种钢焊接接头，可按合金含量较低一侧母材或介于两者母材之间选用焊接材料，也可按合金含量较高一侧母材选用焊接材料，但应优先按合金含量较低一侧母材选用焊接材料。SH/T3526－2004接头类别或组别号手工焊埋弧焊气体保护焊备注焊条焊丝型号焊剂型号对应牌号型号对应牌号焊丝牌号Ⅰ+ⅠE4303J422H08AHJ401-H08AHJ431H08Mn2SiA—E4315J427Ⅰ+（Ⅱ-1）E4303J422H08AH08MnAHJ401-H08AHJ431H10MnSi/H08Mn2SiA—E4315J427Ⅰ+（Ⅱ-2）E4315J427H08MnAHJ401-H08AHJ431H10MnSi/H08Mn2SiA—E5015J507Ⅰ+（Ⅲ-1）Ⅰ+（Ⅲ-2）E4315J427H08AH08MnAHJ401-H08AHJ431H10MnSi/H08Mn2SiA—E5015J507Ⅰ+ⅣE4315J427H08AH08MnAHJ401-H08AHJ401-H08MnAHJ431H10MnSi/H08Mn2SiA—E1-23-13-15A307H1Cr24Ni13—HJ260——Ⅰ+ⅤE4315J427H08AH08MnAHJ401-H08AHJ401-H08MnAHJ431H10MnSi/H08Mn2SiA—E1-23-13-15A307H1Cr24Ni13—HJ260——Ⅰ+ⅥE4315J427H08AH08MnAHJ401-H08AHJ431H10MnSi/H08Mn2SiA—接头类别或组别号手工焊埋弧焊气体保护焊备注焊条焊丝型号型号对应牌号型号对应牌号焊剂焊丝牌号（Ⅳ-1）+（Ⅳ-2）E5515-B1R207—————E5515-B2R307E309-15A307———H1Cr24Ni13不热处理时采用Ⅳ+ⅤE5515-B1R207———H13CrMo—E5515-B2R307—————E5515-B2-VR317E6015-B3R407E310-15A407———H1Cr26Ni21不热处理时采用（Ⅰ-Ⅳ）+ⅧE309-16A302———H1Cr24Ni13不热处理时采用E309-15A3071.2不同奥氏体不锈钢的焊接1）不同奥氏体不锈钢的焊接接头，应选用保证熔敷金属的Cr、Ni、Mo或Cu等的主要合金元素的含量不低于合金含量较低一侧母材标准规定的下限值的焊接材料。2）有防止晶间腐蚀要求的焊接接头，应选用保证熔敷金属中含有稳定化元素Ti、Nb或保证熔敷金属含碳量小于或等于0.04%的焊接材料。3）设计文件对奥氏体焊接材料的熔敷金属内铁素体数有控制时（如特殊的耐腐蚀场合、低温、防止高温σ相脆化以及对磁导率有要求的场合），在订购焊条时应向焊条供货商提出上述要求。4）不同奥氏体不锈钢焊接时，焊接材料可参照下表。接头类别或组别号手工焊埋弧焊气体保护焊备注焊条焊丝型号型号对应牌号型号对应牌号焊剂焊丝牌号（Ⅳ-1）+（Ⅳ-2）E5515-B1R207—————E5515-B2R307E309-15A307———H1Cr24Ni13不热处理时采用Ⅳ+ⅤE5515-B1R207———H13CrMo—E5515-B2R307—————E5515-B2-VR317E6015-B3R407E310-15A407———H1Cr26Ni21不热处理时采用（Ⅰ-Ⅳ）+ⅧE309-16A302———H1Cr24Ni13不热处理时采用E309-15A307项目钢材牌号00Cr19Ni11(304L)0Cr23Ni13(309S)0Cr25Ni20(310S)0Cr17Ni12Mo2(316)00Cr17Ni14Mo2(316L)0Cr19Ni13Mo3(317)0Cr18Ni11Ti(321)钢材牌号焊丝牌号0Cr19Ni9(304)H00Cr21Ni10H0Cr21Ni10H1Cr24Ni13H0Cr21Ni10H1Cr24Ni13H0Cr26Ni21H0Cr21Ni10H0Cr19Ni12Mo2H0Cr21Ni10H0Cr19Ni12Mo2H0Cr21Ni10H0Cr19Ni12Mo2H0Cr20Ni14Mo3H0Cr21Ni1000Cr19Ni11(304L)—H0Cr21Ni10H1Cr24Ni13H0Cr21Ni10H0Cr24Ni13H0Cr26Ni21H0Cr21Ni10H0Cr19Ni12Mo2H00Cr21Ni10H00Cr19Ni12Mo2H0Cr21Ni10H0Cr19Ni12Mo2H0Cr20Ni14Mo3H00Cr21Ni10H0Cr20Ni10TiH0Cr20Ni10Nb0Cr23Ni13(309S)——H1Cr21Ni13H0Cr26Ni21H1Cr24Ni13H0Cr19Ni12Mo2H1Cr24Ni13H00Cr19Ni12Mo2H1Cr24Ni13H0Cr19Ni12Mo2H1Cr24Ni13H0Cr20Ni10TiH0Cr20Ni10Nb0Cr25Ni20(310S)———H0Cr19Ni12Mo2H0Cr19Ni12Mo2H0Cr20Ni14Mo3H0Cr21Ni10H0Cr26Ni210Cr17Ni12Mo2(316)————H0Cr19Ni12Mo2H0Cr19Ni12Mo2H0Cr20Ni14Mo3H0Cr21Ni10H0Cr19Ni12Mo200Cr17Ni14Mo2(316L)—————H0Cr20Ni14Mo3H00Cr19Ni12Mo20Cr19Ni13Mo3(317)——————H0Cr20Ni14Mo3H0Cr21Ni10注1：钢材牌号栏目括号内...
