标准范围

本文件规定了非合金钢和细晶粒钢手工金属极电弧焊的焊态和焊后热处理状态下，最小屈服强度高达500 MPa或最小抗拉强度高达570 MPa的焊条和熔敷金属的分类要求。本文件是一份综合规范，规定使用基于所有焊缝金属屈服强度和平均冲击能量47 J的系统进行分类，或使用基于所有焊缝金属抗拉强度和平均冲击能量27 J的系统进行分类。a） 带有后缀字母“a”的条款、子条款和表格仅适用于根据本文件中所有焊接金属的屈服强度和47 J的平均冲击能量分类为系统的焊条。b） 带有后缀字母“b”的条款、子条款和表格仅适用于根据本文件中所有焊接金属的抗拉强度和27 J的平均冲击能量分类为系统的覆盖焊条。c） 没有后缀字母“A”或后缀字母“B”的条款、子条款和表格适用于本文件中分类的所有覆盖电极。

This document specifies requirements for the 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 non-alloy and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa.This document is a combined specification providing for classification utilizing a system based on the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based on the tensile strength and the average impact energy of 27 J of all-weld metal.a) Clauses, subclauses and tables which carry the suffix letter "A" are applicable only to covered electrodes classified to the system based on the yield strength and the average impact energy of 47 J of all weld metal in this document.b) Clauses, subclauses and tables which carry the suffix letter "B" are applicable only to covered electrodes classified to the system based on the tensile strength and the average impact energy of 27 J of all weld metal in this document.c) Clauses, subclauses and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all covered electrodes classified in this document.
