标准范围

本文件规定了用于抗蠕变和低合金高温应用钢的埋弧焊的实心焊丝电极、管状药芯电极和电极/焊剂组合（全焊接金属沉积物）的分类要求。一个电极可以用不同的通量进行测试和分类。实心丝电极也根据其化学成分单独分类。本文件是一个组合规范，提供了基于以下任一项的分类系统:-实心焊丝电极和全焊接金属沉积物的化学成分；或-全焊缝金属沉积物的拉伸强度以及用电极/助焊剂组合获得的实心丝电极和全焊缝金属沉积物的化学组成。带有后缀字母“A”的条款、子条款和表格仅适用于实心线电极、管状芯电极和所有-根据基于化学成分的系统对焊接金属沉积物进行分类。带有后缀字母“B”的条款、子条款和表格仅适用于实心焊丝电极、管状芯电极和全焊接金属沉积物，这些焊丝电极和全焊接金属沉积物是根据系统根据全焊接金属沉积物的拉伸强度和实心焊丝电极和全焊接金属沉积物的化学成分分类的。不具有后缀字母“A”或后缀字母“B”的条款、子条款和表格适用于根据本文件分类的所有实心线电极、管状芯电极和电极/焊剂组合。

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.

1. 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.
2. 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.
3. 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.
