Welding consumables - Wire electrodes, wires, rods and deposits for gas shielded arc welding of high strength steels - Classification (ISO/DIS 16834:2024)
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.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).

Introduction
This document 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 document.

The classification in accordance with system A was originally based on EN 12534:1999. The classification
in accordance with system B is mainly based upon standards
