英文名称：Welding consumables — Covered electrodes for manual metal arc welding of high-strength steels — Classification

发布日期：2018-08

标准范围

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.
