scope:

This International Standard 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 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) Clauses 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) Clauses 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) Clauses and table entries which carry neither label are applicable to products classified according to either or both systems.
