Welding consumables - Wire electrodes, wires, rods and deposits for gas shielded arc welding of high strength steels - Classification (ISO 16834:2012)
ISO 16834:2012 specifies requirements for classification of wire electrodes, wires, rods and all-weld metal deposits in the as-welded condition and in the post-weld heat-treated (PWHT) condition for gas shielded metal arc welding and tungsten inert-gas welding of high-strength steels with a minimum yield strength greater than 500 MPa, or a minimum tensile strength greater than 570 MPa. One wire electrode can be tested and classified with different shielding gases.
ISO 16834:2012 is a combined specification providing for 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.
Schweißzusätze - Drahtelektroden, Drähte, Stäbe und Schweißgut zum Schutzgasschweißen von hochfesten Stählen - Einteilung (ISO 16834:2012)
Diese Internationale Norm legt Anforderungen für die Einteilung von Drahtelektroden, Drähten, Stäben und dem reinen Schweißgut im Schweißzustand und nach einer Wärmebehandlung (PWHT) für das Metall-Schutzgasschweißen und Wolfram-Inertgasschweißen von hochfesten Stählen mit einer Mindeststreckgrenze über 500 MPa oder einer Mindestzugfestigkeit über 570 MPa fest. Eine Drahtelektrode kann mit verschiedenen Schutzgasen geprüft und eingestuft werden.
Diese Internationale Norm benutzt zur Einteilung ein kombiniertes System, das auf der Einteilung nach der Streckgrenze und der durchschnittlichen Kerbschlagarbeit des reinen Schweißgutes von 47 J beruht oder nach der Zugfestigkeit und der durchschnittlichen Kerbschlagarbeit von 27 J.
e) Abschnitte, Unterabschnitte und Tabellen mit dem zusätzlichen Buchstaben A sind nur für Drahtelektroden, Drähte, Stäbe und Schweißgut anwendbar, die nach dem System eingeteilt sind, das auf Anforderungen an die Streckgrenze und an die durchschnittliche Kerbschlagarbeit von 47 J des reinen Schweißgutes nach dieser Internationalen Norm beruht.
f) Abschnitte, Unterabschnitte und Tabellen mit dem zusätzlichen Buchstaben B sind nur für Drahtelektroden, Drähte, Stäbe und Schweißgut anwendbar, die nach dem System eingeteilt sind, das auf Anforderungen an die Zugfestigkeit und an die durchschnittliche Kerbschlagarbeit von 27 J des reinen Schweißgutes nach dieser Internationalen Norm beruht.
g) Abschnitte, Unterabschnitte und Tabellen ohne zusätzlichen Buchstaben A oder B sind für alle nach dieser Norm eingeteilten Drahtelektroden, Drähte, Stäbe und Schweißgut anwendbar.
Produits consommables pour le soudage - Fils-électrodes, fils, baguettes et dépôts pour le soudage à l'arc sous flux gazeux des aciers à haute résistance - Classification (ISO 16834:2012)
L'ISO 16834:2012 spécifie les exigences relatives à la classification des fils-électrodes, des fils, des baguettes et du métal fondu à l'état brut de soudage ou après traitement thermique après soudage (PWHT) pour le soudage à l'arc sous protection gazeuse et le soudage TIG des aciers à haute résistance ayant une limite d'élasticité minimale supérieure à 500 MPa, ou une limite de résistance à la traction de 570 MPa. Un fil-électrode peut être soumis aux essais et classifié en utilisant différents gaz de protection.
L'ISO 16834:2012 propose une spécification mixte permettant une classification utilisant soit un système basé sur la limite d'élasticité et l'énergie de rupture moyenne de 47 J pour le métal fondu hors dilution, soit un système basé sur la résistance à la traction et l'énergie de rupture moyenne de 27 J pour le métal fondu hors dilution.

Foreword
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 16834 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.
This second edition cancels and replaces the first edition (ISO 16834:2006), which has been technically
revised.
The main changes compared to the previous edition are:
a) in 4.4, the separation between the A and B side has been eliminated;
b) in Table 3B, the chemical composition has been changed for 4M31 and N5M3;
c) footnote a to Table 3B has been redrafted to give more precision;
d) the designation examples in Clause 10 have been modified.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 3 via your national standards body. A complete listing of these bodies can be

ISO 16834:2012(E)
Introduction
This International Standard recognizes that there are two somewhat different approaches in the global market
to classifying a given wire electrode, wire, rod or deposit, and allows for either or both to be used to suit a
particular market need. Application of either type of classification designation (or of both where suitable)
identifies a product as classified in accordance with this International Standard. The classification in
[1]
accordance with system A is mainly based on EN 12534:1999 . The classification in accordance with
system B is mainly based upon standards used around the Pacific Rim. Future revisions will aim to merge the
two systems into a single classification system.
This International Standard provides a classification for the designation of wire electrodes, wires, rods and
deposits 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 to tensile strength of weld metal is generally
higher than that of the 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. Thus, where the application requires matching tensile strength, selection of the consumable should
be made by reference to column 3 of Table 1A or 1B, as appropriate.

Classification
1 Scope
This International Standard specifies requirements for classification of wire electrodes, wires, rods and all-
weld metal deposits in the as-welded condition and in the post-weld heat-treated (PWHT) condition for gas
shielded metal arc welding and tungsten inert-gas welding of high-strength steels with a minimum yield
strength greater than 500 MPa, or a minimum tensile strength greater than 570 MPa. One wire electrode can
be tested and classified with different shielding gases.
This International Standard is a combined specification providing for 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.
e) Clauses, subclauses and tables which carry the suffix letter “A” are applicable only to wire electrodes,
wires, rods and deposits classified according to the system based upon the yield strength and the
average impact energy of 47 J of all-weld metal under this International Standard.
f) Clauses, subclauses and tables which carry the suffix
