BS EN ISO 14343 pdf download Welding consumables — Wire electrodes, strip electrodes, wires and rods for fusion welding of stainless and heat resisting steels — Classification
1 Scope This International Standard specifies 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 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 1 4343-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 1 4343-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.

3 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
3.1
rod
form of welding filler metal, normally packaged in straight lengths, that does not conduct the welding current, for gas tungsten arc and plasma arc welding
3.2
wire
form of welding filler metal, normally packaged as coils, spools or drums, that does not conduct the welding current,for gas tungsten arc, plasma arc welding and laser beam welding
3.3
wire electrode
form of welding filler metal, normally packaged as coils, spools or drums, that becomes part of the welding circuit through which electrical current is conducted, and that terminates at the arc, for gas-shielded metal arc and submerged arc welding
4 Classification
A wire electrode, wire or rod shall be classified according to its chemical composition as listed in Table 1 . The classification is divided into two parts.
a) The first part gives a symbol indicating the product/process to be identified.
b) The second part gives a symbol indicating the chemical composition of the wire electrode, wire or rod.
