Welding consumables - Covered electrodes for manual metal arc welding of high-strength steels - Classification (ISO 18275:2011)

ISO 18275:2011 specifies requirements for classification of covered electrodes and deposited metal in the as-welded condition and in the post-weld heat-treated condition for manual metal arc welding of high-strength steels with a minimum yield strength greater than 500 MPa or a minimum tensile strength greater than 570 MPa.
ISO 18275:2011 is a combined specification providing a classification utilizing a system based upon the yield strength and an average impact energy of 47 J of the all-weld metal, or utilizing a system based upon the tensile strength and an average impact energy of 27 J of the all-weld metal.
Subclauses and tables which carry the suffix letter "A" are applicable only to covered electrodes classified under the system based upon the yield strength and an average impact energy of 47 J of the all-weld metal given in ISO 18275:2011.
Subclauses and tables which carry the suffix letter "B" are applicable only to covered electrodes classified under the system based upon the tensile strength and an average impact energy of 27 J of the all-weld metal given in ISO 18275:2011.
Subclauses and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all covered electrodes classified under ISO 18275:2011.

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.
ISO 18275 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 18275:2005), of which it constitutes a technical
revision. It also incorporates Technical Corrigendum ISO 18275:2005/Cor.1:2007.
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
found at www.iso.org.

ISO 18275:2011(E)
Introduction
This International Standard recognizes that there are two somewhat different approaches in the global market
to classifying a given electrode, 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 accordance with system A is
[1]
mainly based on EN 757:1997 . The classification in accordance with system B is mainly based upon
standards used around the Pacific Rim.
This International Standard provides a classification system for covered electrodes for high-strength steels in
terms of the tensile properties, impact properties and chemical composition of the all-weld metal, as well as
the type of electrode covering. 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 metal.
Therefore, where the application requires matching tensile strength, selection of the consumable should be
made by reference to column 3 of Table 1A or column 2 of Table 8B.
It should be noted that the mechanical properties of all-weld metal test specimens used to classify covered
electrodes can vary from those obtained in production joints because of differences in welding procedure such
as electrode size, width of weave, welding position, and parent metal composition.
