标准摘要
[中文适用范围]： 本文件规定了用于气渣冷弧焊、气钨电弧焊、等离子电弧焊、埋弧焊、电渣焊和激光束焊的不绣钢和热抵抗钢用焊丝电极、带状电极、焊丝和焊条的分类要求。这些焊丝电极、带状电极、焊丝和焊条的分类依据为它们的化学成分。本文件是一个联合规范，提供了一种基于公称组成（系统 A）或基于合金类型（系统 B）的分类方法。 [外文原描述]： This document specifies requirements for classification of wire electrodes, strip electrodes, wires and rods for gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, electroslag welding and laser beam welding of stainless and heat-resisting steels. The classification of the wire electrodes, strip electrodes, wires and rods is based upon their chemical composition. This document is a combined specification providing for classification utilizing a system based upon nominal composition (system A), or utilizing a system based upon alloy type (system B). a) Paragraphs which carry the label “classification according to nominal composition” and the suffix “system A”, or “ISO 14343-A”, are applicable only to products classified according to system A; b) Paragraphs which carry the label “classification according to alloy type” and the suffix “system B”, or “ISO 14343-B”, are applicable only to products classified according to system B. c) Paragraphs which carry neither label nor suffix letter are applicable to products that can be classified according to either system A or B or both.
