Welding consumables - Tubular cored electrodes for gas-shielded and non-gas-shielded metal arc welding of high-strength steels - Classification (ISO 18276:2005)
ISO 18276:2005 specifies requirements for classification of tubular cored electrodes with or without a gas shield for metal arc welding of high-strength steels in the as-welded condition or in the post-weld heat-treated condition with a minimum yield strength higher than 550 MPa or a minimum tensile strength higher than 590 MPa. One tubular cored electrode can be tested and classified with different shielding gases, if used with more than one.
This document is a combined specification providing 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.
Schweißzusätze - Fülldrahtelektroden zum Metall-Schutzgasschweißen mit und ohne Schutzgas von hochfesten Stählen - Einteilung (ISO 18276:2005)
Diese Internationale Norm legt Anforderungen fest für die Einteilung von Fülldrahtelektroden zum Metall-
Lichtbogenschweißen von hochfesten Stählen mit oder ohne Gasschutz mit einer Mindeststreckgrenze über
550 MPa oder einer Mindestzugfestigkeit über 590 MPa im Schweißzustand oder nach einer
Wärmenachbehandlung. Eine Fülldrahtelektrode kann mit verschiedenen Schutzgasen geprüft und eingeteilt
werden, falls sie mit mehr als einem Schutzgas angewendet wird.
Dieses Dokument enthält gemeinsame Anforderungen zur Einteilung des reinen Schweißgutes entweder nach
der Streckgrenze und der durchschnittlichen Kerbschlagarbeit von 47 J oder nach der Zugfestigkeit und der
durchschnittlichen Kerbschlagarbeit von 27 J.
1) Abschnitte und Tabellen, gekennzeichnet durch ein nachgestelltes 'A', können nur für Fülldrahtelektroden
angewendet werden, die nach der Streckgrenze und der durchschnittlichen Kerbschlagarbeit
von 47 J des reinen Schweißgutes in dieser Internationalen Norm eingeteilt werden.
2) Abschnitte und Tabellen, gekennzeichnet durch ein nachgestelltes 'B', können nur für Fülldrahtelektroden
angewendet werden, die nach der Zugfestigkeit und der durchschnittlichen Kerbschlagarbeit
von 27 J des reinen Schweißgutes in dieser Internationalen Norm eingeteilt werden.
3) Abschnitte und Tabellen, die weder ein nachgestelltes 'A' noch 'B' enthalten, sind für alle nach dieser
Internationalen Norm eingeteilten Fülldrahtelektroden anwendbar.
Es ist bekannt, dass die Schweißeigenschaften von Fülldrahtelektroden durch die Anwendung von
pulsierendem Strom beeinflusst werden können, jedoch ist in dieser Internationalen Norm pulsierender Strom
nicht für die Einteilung der Fülldrahtelektroden vorgesehen.

L'ISO 18276:2005 spécifie les exigences relatives à la classification des fils-électrodes fourrés pour soudage à l'arc avec ou sans gaz de protection pour l'état brut de soudage ou pour l'état traité thermiquement après soudage des aciers à haute résistance ayant une limite d'élasticité minimale supérieure à 550 MPa ou une résistance à la traction minimale supérieure à 590 MPa. Un fil-électrode peut, le cas échéant, être essayé et classifié avec différents gaz de protection.
L'ISO 18276:2005 propose une spécification mixte permettant une classification utilisant un système basé soit sur la limite d'élasticité et l'énergie de rupture moyenne de 47 J pour le métal fondu hors dilution, soit 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 18276 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.

Introduction
This International Standard proposes a classification system for tubular cored electrodes in terms of the
tensile properties, impact properties, chemical composition of the all-weld metal, type of electrode core,
shielding gas and welding position. The ratio of yield strength to tensile strength of the 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 will not necessarily ensure that the weld metal tensile strength matches that of the parent metal.
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.
It should be noted that the mechanical properties of all-weld metal test specimens used to classify tubular
cored electrodes will differ from those obtained with production joints because of differences in welding
procedure such as electrode size, width of weave, welding position and parent metal composition.
The classification in accordance with system A is mainly based on EN 12535:2000, Welding consumables —
Tubular cored electrodes for gas shielded metal arc welding of high strength steels — Classification. The
classification in accordance with system B is mainly based upon standards used around the Pacific Rim.
Requests for official interpretation of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 3 via the user's national standardization body. A complete listing of these bodies
can be found at .
