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.

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 on 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 on the tensile strength and the average impact energy of 27 J of all-weld metal

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.

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.

Welding consumables — Wire electrodes and weld
deposits for gas shielded metal arc welding of non alloy
and fine grain steels — Classification
1 Scope
This document specifies requirements for classification of wire electrodes and weld deposits in the as-
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
