ISO 14341:2002规定了最小屈服强度高达500 N/mm2或最小抗拉强度高达570 N/mm2的非合金钢和细晶粒钢的气体保护金属电弧焊的焊接状态和焊后热处理状态下焊丝的分类要求。一根线电极可以用不同的保护气体进行测试和分类。 本文件构成了利用基于全焊接金属的屈服强度和47J的平均冲击能量的系统或利用基于全焊接金属的拉伸强度和27J的平均冲击能量的系统提供分类的组合规范。

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.
