This International Standard specifies requirements for classification of solid wire electrodes, tubular cored electrodes, and electrode/flux combinations (all-weld metal deposits) in the as-welded condition and in the post weld heat-treated condition for submerged arc welding of high strength steels with a minimum yield strength greater than 500 MPa or a minimum tensile strength greater than 570 MPa. One flux can be tested and classified with different electrodes. 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 for classification utilizing a system based upon the yield strength and average impact energy of 47 J for all-weld metal, or utilizing a system based upon the tensile strength and average impact energy of 27 J for all-weld metal. 1) Paragraphs and tables which carry the suffix letter “A” are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified to the system based upon the yield strength and the average impact energy of 47 J for all-weld metal obtained with electrode/flux combinations in accordance with this International Standard. 2) Paragraphs and tables which carry the suffix letter “B” are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified to the system based upon the tensile strength and the average impact energy of 27 J for all-weld metal obtained with electrode/flux combinations in accordance with this International Standard. 3) Paragraphs 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 in accordance with this International Standard.
