ISO 14171:2002 Welding consumables - Wire electrodes and wire-flux combinations for submerged arc welding of non alloy and fine grain steels - Classification
This International Standard 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/mm or a minimum tensile strength of up to 570 N/mm. 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.
1) Paragraphs and tables which carry the suffix letter "A" are applicable only to wire-flux combinations and wire electrodes classified using the system based upon the yield strength and the average impact energy for all-weld metal of 47 J, in accordance with this International Standard.
2) Paragraphs and tables which carry the suffix letter "B" are applicable only to wire-flux combinations and wire electrodes classified using the system based upon the tensile strength and the average impact energy for all-weld metal of 27 J, in accordance with this International Standard.
3) Paragraphs and tables which have neither the suffix letter "A" nor the suffix letter "B" are applicable to all wire-flux combinations and wire electrodes classified in accordance with this International Standard.
Fluxes for the single-run and two-run techniques are classified on the basis of the two-run technique.
