Ce document traite de la classification des fils électrodes nus massifs pour le soudage à l'arc sous gaz de protection destinés au soudage des aciers non alliés et des aciers à grain fin. Cette classification se divise en cinq parties : produit et/ou procédé ; résistance et allongement du métal fondu ; résistance à la flexion par choc du métal fondu ; gaz de protection et composition chimique du fil électrode.
ISO 14341:2002 specifies requirements for classification of wire electrodes in the as-welded condition and in the post weld heat-treated condition for gas shielded metal 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 wire electrode can be tested and classified with different shielding gases. This document constitutes a combined specification providing classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal.
