ISO 14171:2002

ISO 14171:2002 specifies requirements for the classification of wire-flux combinations and all-weld metal in the as-welded condition and in the post weld heat-treated condition for submerged arc welding of non alloy and fine grain steels with a minimum yield strength of up to 500 N/mm2 or a minimum tensile strength of up to 570 N/mm2. One flux may be classified with different wire electrodes. The wire electrode is also classified separately based on its chemical composition. This document constitutes a combined specification providing classification utilizing a system based upon the yield strength and the average impact energy for all-weld metal of 47 J, or utilizing a system based upon the tensile strength and the average impact energy for all-weld metal of 27 J.
