1 Scope This standard specifies the technical requirements of the welding on dissimilar steel for power plant.This standard applies to the welding work on dissimilar steels of the welded compression components or of the non-compression components on the pressure-bearing components by adopting with such welding methods as shielded metal arc welding, argon tungsten-arc welding, consumable electrode gas shielded welding, flux-cored wire electric arc welding and submerged arc welding. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent amendments (excluding error in the text) to, or revisions of, any of these publications do not be applied. However, the parties coming to an agreement according to these specifications are encouraged to study whether the latest editions of these standards are applicable to this standard.For undated references, the latest edition of the normative document is applicable to this standard.GB/T17394 Metallic Materials-Leeb Hardness Test GB/T713 Steel Plates for Boiler and Pressure Vessels GB/T1220 Stainless Steel Bars GB/T1221 Heat-Resistant Steel Bars GB/T1591 High Strength Low Alloy Structural Steels GB/T5310 Seamless Steel Tubes and Pipes for High Pressure Boiler DL/T 679 Code for Welder Technical Qualification DL/T 819 The Code of the Welding Heat Treatment for Power Plant DL/T 868 The Code of Welding Procedure Qualification DL/T 869 The Code of the Welding for Power Plant DL/T 884 Power Plant Metallography Inspection and Assessment Guideline JB/T 3223 The Code of the Quality Management of Welding Materials JB/T 9625 Specification for Pressure Retaining Casting of Boller Pipe Fittings 3 General Requirements 3.1 Division of welded joints for dissimilar steels 3.1.1 Group divisions of common steels are shown as Table1.
