焊接耗材 抗蠕变钢气体保护电弧焊用焊丝、焊丝、焊条和焊料 分类

[中文适用范围]： 本文件规定了用于气 shielded 金属电弧 welding 和钨极惰性气体 welding 的耐热钢焊丝和焊棒的分类要求及其沉积物在焊接后或热处理状态下的要求。一根焊丝可以使用不同的保护气体进行测试和分类。 本文件是一个综合规范，提供基于焊丝、焊条和焊棒的化学成分以及所有焊缝金属的屈服强度和平均冲击能量为 47 J 进行分类的系统；或基于所有焊缝金属沉积物的抗拉强度和焊丝、焊条和焊棒的化学成分为依据进行分类的系统。 本文件中的条款、子条款和表格带有后缀“系统 A”的，仅适用于根据基于化学成分的分类方法（并要求所有 weld 金属的屈服强度和平均冲击能量为 47 J）对焊丝、焊条、焊棒及其沉积物进行分类的情况。 本文件中的条款、子条款和表格带有后缀“系统 B”的，仅适用于根据基于 all-weld 金属沉积物的抗拉强度和焊丝、焊条和焊棒的化学成分进行分类的情况。 本文件中没有带有“系统 A”或“系统 B”后缀的条款、子条款和表格适用于本文件下所有分类的焊丝、焊条、焊棒及其沉积物。 [外文原描述]： This document specifies requirements for classification of wire electrodes, wires and rods for gas shielded metal arc welding and tungsten inert-gas welding of creep-resisting steels, and for their deposits in the as-welded or post-weld heat-treated condition. One wire electrode can be tested and classified with different shielding gases. This document is a combined specification providing for classification utilizing a system based upon the chemical composition of wire electrodes, wires and rods with requirements for yield strength and average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength of the all-weld metal deposits and the chemical composition of wire electrodes, wires and rods. a) Clauses, subclauses and tables which carry the suffix “system A” are applicable only to wire electrodes, wires, rods and deposits classified in accordance with the system based upon the chemical composition with requirements for yield strength and the average impact energy of 47 J of all-weld metal deposits under this document. b) Clauses, subclauses and tables which carry the suffix “system B” are applicable only to wire electrodes, wires, rods and deposits classified in accordance with the system based upon the tensile strength of all‑weld metal deposits and the chemical composition of wire electrodes, wires and rods under this document. c) Clauses, subclauses and tables which do not have either the suffix “system A” or the “system B” are applicable to all wire electrodes, wires, rods and deposits classified under this document.
