发布日期：2011-05

标准范围

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