Description:This International Standard specifies requirements for classification of wire electrodes, wires and rods for gasshielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding and laser beam welding of stainless and heat resisting steels. The classification of the wire electrodes, wires and rods is based upon their chemical composition. This document is a combined standard providing for classification utilizing a system based upon classification according to nominal composition or utilizing a system based upon classification according to alloy type. a) Paragraphs and table entries which carry the label “classification according to nominal composition”, or which are identified by “ISO 14343-A”, are applicable only to products classified to that system. b) Paragraphs and table entries which carry the label “classification according to alloy type”, or which are identified by “ISO 14343-B”, are applicable only to products classified to that system. c) Paragraphs and table entries which carry neither label are applicable to products classified according to either or both systems.  
Overview: Welding consumables. Wire electrodes, strip electrodes, wires and rods for fusion welding of stainless and heat resisting steels. ClassificationBS EN ISO 14343 specifies the requirements for classification of wire electrodes, wires and rods for gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding and laser beam welding of stainless and heat resisting steels. The classification of the wire electrodes, wires and rods is based upon their chemical composition.This standard provides for classification utilizing a system based upon classification according to nominal composition, or utilizing a system based upon classification according to alloy type.Paragraphs and table entries which carry the label “classification according to nominal composition”, or which are identified by “ISO 14343-A”, are applicable only to products classified to that system Paragraphs and table entries which carry the label “classification according to alloy type”, or that are identified by “ISO 14343-B”, are applicable only to products classified to that system Paragraphs and table entries which carry neither label are applicable to products classified according to either or both systems.It is recognized that there are two somewhat different approaches in the global market to classifying a given stainless steel welding consumable, and that market allows for either or both to be used, to suit a particular market need. One is termed the “Nominal Composition” approach, which uses designators that indicate the principal alloying elements at their nominal levels, in a particular sequence, sometimes followed by chemical element symbols to indicate compositional modifications to the original grade. The other is termed the “Alloy Type” approach, which uses tradition-based three or four digit designations for certain original grades, sometimes followed by one or more chemical element symbols which indicate compositional modifications from the original. In both approaches, classification is based upon the chemical composition of the product. In many cases a given product can be classified using both approaches, because the composition ranges, although slightly different, overlap to a considerable extent, in the two approaches.Application of either type of classification designation (or both where suitable) identifies a product as classified according to this international standard. Many, but not all, commercial products addressed by this international standard can be classified using both approaches, and suitable products may be so marked. The classification according to system A is mainly based on BS EN 12072. The classification according to system B is mainly based upon standards used around the Pacific Rim.For stainless steel welding consumables, there is no unique relationship between the product form (wire electrode, wire or rod) and the welding process used (gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding or submerged arc welding). For this reason, the wire electrodes, wires or rods may be classified on the basis of any of the above product forms and can be used, as appropriate, for more than one of the above processes.Contents include:Foreword Introduction Scope Normative references Terms and definitions Classification Symbol for the product/process Symbol for the chemical composition Properties of the all-weld metal Chemical analysis Technical delivery conditions Examples of designation Expected minimum tensile properties of all-weld metalBS EN ISO 14343:2007 replaces BS EN 12072:2000 which has been withdrawn
