标准摘要
[中文适用范围]: 本文件规定了抗蠕变钢和低合金高温应用钢埋弧焊用的实心焊丝、管状药芯焊丝和焊条/焊剂组合(全焊缝金属沉积物)的分类要求。一种焊条可以用不同的焊剂进行试验和分类。实心焊丝也基于其化学成分单独分类。本文件是一个综合规范,提供基于下列内容的分类系统: — 实心焊丝和全焊缝金属沉积物的化学成分;或 — 全焊缝金属沉积物的抗拉强度以及用焊条/焊剂组合获得的实心焊丝和全焊缝金属沉积物的化学成分。 a) 带有后缀字母“A”的条款、子条款和表格仅适用于按照基于化学成分的系统分类的实心焊丝、管状药芯焊丝和全焊缝金属沉积物。 b) 带有后缀字母“B”的条款、子条款和表格仅适用于按照基于全焊缝金属镀层抗拉强度和实心焊丝电极与全焊缝金属镀层化学成分的系统分类的实心焊丝、管状药芯焊条和全焊缝金属镀层。 c) 不带后缀字母“A”或后缀字母“B”的条款、子条款和表格适用于本文件分类的所有实心焊丝、管状药芯焊条和焊条/焊剂组合。 [外文原描述]: This document specifies requirements for classification of solid wire electrodes, tubular cored electrodes and electrode/flux combinations (all-weld metal deposits) for submerged arc welding of creep resisting and low-alloy elevated-temperature application steels. One electrode can be tested and classified with different fluxes. The solid wire electrode is also classified separately based on its chemical composition. This document is a combined specification providing a classification system based on either: — the chemical composition of the solid wire electrode and all-weld metal deposit; or — the tensile strength of the all-weld metal deposit and the chemical composition of the solid wire electrode and all-weld metal deposit obtained with the electrode/flux combination. Clauses, subclauses and tables which carry the suffix letter "A" are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified in accordance with the system based upon chemical composition. Clauses, subclauses and tables which carry the suffix letter "B" are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified in accordance with the system based upon the tensile strength of all-weld metal deposits and the chemical composition of solid wire electrodes and all-weld metal deposits. Clauses, subclauses and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all solid wire electrodes, tubular cored electrodes and electrode/flux combinations classified under this document.
