NF EN ISO 14343, A81-313 (01/2025)

ISO 14343:2017 specifies requirements for the classification of wire electrodes, strip electrodes, filler wires and welding rods, for gas shielded metal arc welding, gas shielded arc welding gas protection with tungsten electrode (TIG welding), plasma welding, submerged arc welding, slag welding (electroconductive) and laser welding of stainless steels and steels resistant to high temperatures. The classification of wire electrodes, strip electrodes, filler wires and welding rods is based on their chemical composition. This document allows the use of two parallel classification systems, by nominal composition (system A) and/or by type of alloy (system B). a) Paragraphs marked “classification according to nominal composition” and the letter “A”, or “ISO 14343-A”, are only applicable to products classified according to system A; (b) paragraphs marked “classification according to alloy type” and the letter “B”, or “ISO 14343-B”, are only applicable to products classified according to system B; (c) paragraphs which bear no mention or letter are applicable to products classified either according to system A, or according to system B, or according to systems A and B.
