Welding consumables - Solid wire electrodes, tubular cored electrodes and electrode/flux combinations for submerged arc welding of creep-resisting steels - Classification (ISO 24598:2007)
ISO 24598:2007 specifies requirements for classification of solid wire electrodes, tubular cored electrodes and electrode/flux combinations (all-weld metal deposits) for submerged arc welding of creep-resisting and low-alloy elevated-temperature steels. One flux can be tested and classified with different electrodes. One electrode can be tested and classified with different fluxes. The solid wire electrode is also classified separately based on its chemical composition.
ISO 24598:2007 is a combined specification providing for classification utilizing a system based upon the chemical composition of the solid wire electrode and all-weld metal deposit, or utilizing a system based upon the tensile strength of the all-weld metal deposit and the chemical composition of the solid wire electrode and all-weld metal deposit obtained with the electrode/flux combination.
Schweißzusätze - Drahtelektroden, Fülldrahtelektroden und Draht-Pulver-Kombinationen für das Unterpulverschweißen von warmfesten Stählen - Einteilung (ISO 24598:2007)
Diese Internationale Norm legt Anforderungen für die Einteilung von Massiv-Drahtelektroden, Fülldraht¬elektroden und Draht-Pulver-Kombinationen (reines Schweißgut) zum Unterpulverschweißen warmfester und niedriglegierter Stähle für erhöhte Temperatur fest. Ein Pulver kann mit verschiedenen Drahtelektroden geprüft und eingestuft werden. Eine Drahtelektrode kann mit verschiedenen Pulvern geprüft und eingestuft werden. Die Massiv-Drahtelektrode kann auch gesondert nach ihrer chemischen Zusammensetzung eingestuft werden.
Diese Internationale Norm benutzt zur Einteilung ein kombiniertes System, das auf der Einteilung nach der chemischen Zusammensetzung der Massiv-Drahtelektroden und des reinen Schweißgutes beruht oder auf der Zugfestigkeit des reinen Schwei߬gutes sowie der chemischen Zusammensetzung der Massiv-Drahtelektroden und des mit einer Draht-Pulver-Kombination hergestellten reinen Schweißgutes.
1) Abschnitte, Unterabschnitte und Tabellen mit dem zusätzlichen Buchstaben „A“ sind nur für Massiv-Drahtelektroden, Fülldrahtelektroden und reines Schweißgut anwendbar, die nach dem System eingeteilt sind, das auf der chemischen Zusammensetzung beruht.
2) Abschnitte, Unterabschnitte und Tabellen mit dem zusätzlichen Buchstaben „B“ sind nur für Massiv-Drahtelektroden, Fülldrahtelektroden und reines Schweißgut anwendbar, die nach dem System eingeteilt sind, das auf den Anforderungen an die Zugfestigkeit des reinen Schweißgutes und die chemische Zusammensetzung der Massiv-Drahtelektroden und des reinen Schweißgutes beruht.
3) Abschnitte, Unterabschnitte und Tabellen ohne zusätzlichen Buchstaben „A“ oder „B“ sind für alle nach dieser Norm eingeteilten Massiv-Drahtelektroden, Fülldrahtelektroden und Draht-Pulver-Kombinationen anwendbar.
Produits consommables pour le soudage - Fils-électrodes pleins, fils-électrodes fourrés et couples fil-flux pour le soudage à l'arc sous flux des aciers résistant au fluage - Classification (ISO 24598:2007)
L'ISO 24598:2007 spécifie les exigences relatives à la classification des fils-électrodes pleins, des fils-électrodes fourrés et des combinaisons fil-flux (dépôts de métal fondu hors dilution) pour le soudage à l'arc sous flux des aciers résistant au fluage et des aciers faiblement alliés pour hautes températures. Un flux peut être essayé et classifié avec différentes électrodes. Une électrode peut être essayée et classifiée avec différents flux. Un fil-électrode plein est également classifié séparément d'après sa composition chimique.
L'ISO 24598:2007 propose une spécification mixte permettant une classification utilisant soit un système basé sur la composition chimique des fils-électrodes pleins et des dépôts de métal fondu hors dilution, soit un système basé sur la résistance à la traction du métal fondu hors dilution et la composition chimique des fils-électrodes pleins et des dépôts de métal fondu hors dilution obtenus avec des couples fil-flux.

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 24598 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.
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 listing of these bodies can be found at

Introduction
This International Standard provides a classification in order to designate solid wire electrodes in terms of their
chemical composition, solid wire electrodes and tubular cored electrodes in terms of the deposit composition
obtained with a particular submerged arc flux and, where required, electrode-flux combinations in terms of the
yield strength, tensile strength and elongation of the all-weld metal deposit. The ratio of yield 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 will not necessarily ensure that the weld metal tensile
strength matches that of the parent material. Where the application requires matching tensile strength,
therefore, selection of the consumable should be made by reference to column 3 of Table 1A or Table 1B, as
appropriate.
Although combinations of wire electrodes and fluxes supplied by individual companies may have the same
grading, the individual wire electrodes and fluxes from different companies are not interchangeable unless
verified in accordance with this International Standard.
It should be noted that the mechanical properties of all-weld metal test pieces used to classify the wire
electrodes will vary from those obtained in production joints because of differences in welding procedure such
as electrode size, welding position and material composition.
This International Standard recognizes that there are two somewhat different approaches in the global market
to classifying a given wire electrode, tubular cored electrode or electrode/flux combination, 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 mainly based on EN 12070:1999. 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 approaches into a single classification system.
