ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO

collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

Introduction

This document recognizes that there are two somewhat different approaches in the global market to

classifying a given wire electrode, and allows for either or both to be used, to suit a particular market

need. Application of either type of classification designation (or both where suitable) identifies a product

as classified in accordance with this document.

This document provides a classification in order to designate wire electrodes in terms of their chemical

composition and, where required, in terms of the yield strength, tensile strength and elongation of the

all-weld metal. The ratio of yield strength to tensile strength of weld metal is generally higher than that

of parent metal. Users should note that matching weld metal yield strength to parent metal yield strength

does not necessarily ensure that the weld metal tensile strength matches that of the parent material.

Therefore, where the application requires matching tensile strength, selection of the consumable should

be made by reference to column 3 of Table 1A or 1B.

It should be noted that the mechanical properties of all-weld metal test specimens used to classify the

electrodes vary from those obtained in production joints because of differences in welding procedures

such as electrode size, width of weave, welding position and material composition.

welded condition and in the post-weld heat-treated condition for gas shielded metal arc welding of non

alloy and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength

of up to 570 MPa. One wire electrode can be tested and classified with different shielding gases.

This document constitutes a combined specification providing classification utilizing a system based

upon the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system

based upon the tensile strength and the average impact energy of 27 J of all-weld metal.

a) Clauses and tables which carry the suffix letter “A” are applicable only to wire electrodes classified

to the system based upon the yield strength and the average impact energy of 47 J of all-weld metal in

accordance with this document.

b) Clauses and tables which carry the suffix letter “B” are applicable only to wire electrodes classified

to the system based upon the tensile strength and the average impact energy of 27 J of all-weld metal in

accordance with this document.

c) Clauses and tables which have neither the suffix letter “A” nor the suffix letter “B” are applicable to

all wire electrodes classified in accordance with this document.

4 Classification

Classification designations are based upon two approaches to indicate the tensile properties and the

impact properties of the all-weld metal obtained with a given electrode. The two designation approaches

include additional designators for some other classification requirements, but not all, as will be clear from

the following subclauses. In most cases, a given commercial product can be classified in both systems.

Then either or both classification designations can be used for the product.

A wire electrode shall be classified according to its chemical composition as in Table 3A or Table 3B. A

weld deposit shall be classified with additional symbols according to the mechanical properties of its all-

weld metal, using a shielding gas from a specific group.

4A Classification by yield strength and 47 J 4B Classification by tensile strength and 27 J

impact energy impact energy

The classification is divided into five parts: The classification is divided into five parts:

1) the first part gives a symbol indicating the 1) the first part gives a symbol indicating the

product/process to be identified; product/process to be identified;

2) the second part gives a symbol indicating 2) the second part gives a symbol indicating

the strength and elongation of the all-weld metal the strength and elongation of the all-weld metal

(see Table 1A); in either the as-welded or post-weld heat-treated
condition (see Table 1B);

3) the third part gives a symbol indicating 3) the third part gives a symbol indicating

the impact properties of the all-weld metal (see the impact properties of the all-weld metal in the

Table 2); same condition as specified for the tensile
strength (see Table 2). The letter U after this
symbol indicates that the deposit meets an
average optional requirement of 47 J at the
designated Charpy test temperature;

4) the fourth part gives a symbol indicating 4) the fourth part gives a symbol indicating

the shielding gas used (see 5.4); the shielding gas used (see 5.4);

5) the fifth part gives a symbol indicating the 5) the fifth part gives a symbol indicating the

chemical composition of the wire electrode used chemical composition of the wire electrode used

(see Table 3A). (see Table 3B).
