EN 12070:1999

Introduction

For creep-resisting steel welding consumables it should be noted that the me- chanical properties of all-weld metal test specimens used for classification will vary from those obtained in production joints because of differences in welding conditions, material composition and shielding gas or flux.

Although combinations of wires and fluxes supplied by individual companies can have the same grading, the individual wires and fluxes from different companies are not interchangeable unless verified in accordance with this standard.

1 Scope

This standard specifies requirements for classification of wire electrodes, wires and rods for gas tungsten arc welding, gas shielded metal arc welding and sub- merged arc welding of creep-resisting and low alloy elevated temperature steels.

The classification of the wire electrodes, wires and rods is based on their chemical composition.

2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

EN 759 Welding consumables – Technical delivery conditions for welding filler metals – Type of product, dimensions, tolerances and mark- ing

EN 1597-1 Welding consumables – Test methods – Part 1: Test piece for all- weld metal test specimens in steel, nickel and nickel alloys

EN ISO 13916 Welding – Guidance on the measurement of preheating tempera- ture, interpass temperature and preheat maintenance tempera- ture (ISO 13916:1996)

ISO 31-0:1992 Quantities and units – Part 0: General principles

3 Classification

A wire electrode, wire or rod is classified in accordance with its chemical composi- tion in table 1.

When the wire electrode, wire or rod is classified in combination with a gas or flux for welding the classification shall be prefixed with a symbol in accordance with clause 4 as appropriate.

As a consequence 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.

4 Symbols and requirements

4.1 Symbol for the product/process

The symbol for the wire electrode, wire or rod used in the arc welding process shall be the letter G (gas shielded metal arc welding), S (submerged arc welding) and/or W (gas tungsten arc welding).
