标准范围

本文件规定了最低屈服强度大于500 MPa或最低抗拉强度大于570 MPa的高强度钢手工金属电弧焊焊态和焊后热处理状态下的焊条和熔敷金属分类要求。本文件是一份综合规范，使用基于屈服强度和47 J全焊缝金属平均冲击能量的系统，或使用基于拉伸强度和27 J全焊缝金属平均冲击能量的系统，提供分类。a） 带有后缀字母“a”的子条款和表格仅适用于根据本文件中给出的所有焊接金属的屈服强度和47 J的平均冲击能量分类在系统下的覆盖焊条。b） 带有后缀字母“b”的子条款和表格仅适用于根据抗拉强度和27 J的平均冲击能量分类在系统下的覆盖电极-本文件中给出的焊接金属。c） 没有后缀字母“A”或后缀字母“B”的子条款和表格适用于根据本文件分类的所有覆盖电极。

This document specifies requirements for classification of covered electrodes and deposited metal in the as-welded condition and in the post-weld heat-treated condition for manual metal arc welding of high-strength steels with a minimum yield strength greater than 500 MPa or a minimum tensile strength greater than 570 MPa.This document is a combined specification providing a classification utilizing a system based on the yield strength and an average impact energy of 47 J of the all-weld metal, or utilizing a system based on the tensile strength and an average impact energy of 27 J of the all-weld metal.a) Subclauses and tables which carry the suffix letter "A" are applicable only to covered electrodes classified under the system based on the yield strength and an average impact energy of 47 J of the all-weld metal given in this document.b) Subclauses and tables which carry the suffix letter "B" are applicable only to covered electrodes classified under the system based on the tensile strength and an average impact energy of 27 J of the all-weld metal given in this document.c) Subclauses and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all covered electrodes classified under this document.
