BS EN ISO 14343:2017规定了不锈钢和耐热钢的气体保护金属极电弧焊、钨极气体保护焊、等离子弧焊、埋弧焊、电渣焊和激光束焊接用焊丝、条形焊条、焊丝和棒材的分类要求。金属丝电极、条形电极、金属丝和金属棒的分类基于其化学成分。本文件是一份综合规范，规定使用基于标称成分的系统（系统a）或基于合金类型的系统（系统B）进行分类。a） 带有标签“根据标称成分分类”和后缀字母“a”或“ISO 14343”的段落- A）仅适用于根据系统A分类的产品；b）带有“根据合金类型分类”标签和后缀字母“b”或“ISO 14343-b”的段落“，仅适用于根据系统B分类的产品。c）没有标签或后缀字母的段落适用于可以根据系统A或B或两者分类的产品。交叉引用:ISO 544:2011 Ed 4ISO 14344:2010 Ed 2ISO 80000-1:2009 Ed 1 EN 12072:1999购买本d时可用的所有当前修订均包含在购买中文件。

BS EN ISO 14343:2017 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 letter "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 letter "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.Cross References:ISO 544:2011 Ed 4ISO 14344:2010 Ed 2ISO 80000-1:2009 Ed 1 EN 12072:1999All current amendments available at time of purchase are included with the purchase of this document.
