(Main)Welding consumables - Tubular cored electrodes for gas-shielded and non-gas-shielded metal arc welding of high strength steels - Classification (ISO 18276:2017)
Welding consumables - Tubular cored electrodes for gas-shielded and non-gas-shielded metal arc welding of high strength steels - Classification (ISO 18276:2017)
ISO 18276:2017 specifies the 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.
ISO 18276:2017 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.
- Subclauses and tables which carry the suffix letter "A" are applicable only to tubular cored 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 this document.
- Subclauses and tables which carry the suffix letter "B" are applicable only to tubular cored 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 this document.
- Subclauses and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all tubular cored electrodes classified under this document.
It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed current but, for the purposes of this document, pulsed current is not used for determining the electrode classification.
Schweißzusätze - Fülldrahtelektroden zum Metall-Lichtbogenschweißen mit und ohne Schutzgas von hochfesten Stählen - Einteilung (ISO 18276:2017)
Diese Internationale Norm legt Anforderungen fest für die Einteilung von Fülldrahtelektroden zum Metall-Lichtbogen¬schweißen von hochfesten Stählen mit oder ohne Gasschutz mit einer Mindeststreckgrenze über 550 MPa oder einer Mindestzugfestigkeit über 590 MPa im Schweißzustand oder nach einer Wärmenach-behandlung. 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 Fülldraht¬elek-troden angewendet werden, die nach der Streckgrenze und der durchschnittlichen Kerb¬schlag¬arbeit von 47 J des reinen Schweißgutes in dieser Internationalen Norm eingeteilt werden.
2) Abschnitte und Tabellen, gekennzeichnet durch ein nachgestelltes „B“, können nur für Fülldraht¬elek-troden 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 Inter¬nationalen Norm eingeteilten Fülldrahtelektroden anwendbar.
Es ist bekannt, dass die Schweißeigenschaften von Fülldrahtelektroden durch die Anwendung von pul-sieren¬dem Strom beeinflusst werden können, jedoch ist in dieser Internationalen Norm pulsierender Strom nicht für die Einteilung der Fülldrahtelektroden vorgesehen.
Produits consommables pour le soudage - Fils-électrodes fourrés pour le soudage à l'arc avec ou sans gaz de protection des aciers à haute résistance - Classification (ISO 18276:2017)
L'ISO 18276:2017 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 18276:2017 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.
1) Les paragraphes et les tableaux qui portent le suffixe «A» ne sont applicables qu'aux fils-électrodes fourrés classifiés d'après le système basé sur la limite d'élasticité et l'énergie de rupture moyenne de 47 J pour le métal fondu hors dilution conformément à la présente Norme internationale.
2) Les paragraphes et les tableaux qui portent le suffixe «B» ne sont applicables qu'aux fils-électrodes fourrés classifiés d'après le système basé sur la résistance à la traction et l'énergie de rupture moyenne de 27 J pour le métal fondu hors dilution conformément à l'ISO 18276:2017.
3) Les paragraphes et les tableaux qui ne portent ni le suffixe «A» ni le suffixe «B» sont applicables à tous les fils-électrodes fourrés classifiés conformément à la présente Norme internationale.
Il est connu que les caractéristiques d'emploi d'un fil-électrode fourré peuvent être modifiées par l'utilisation de courant pulsé mais, pour les besoins du présent document, le courant pulsé n'est pas utilisé pour la détermination de la classification d'un fil-électrode.
Dodajni materiali za varjenje - Strženske žice iz cevi za obločno varjenje nerjavnih in ognjeodpornih jekel v zaščitnem plinu in brez zaščite - Razvrščanje (ISO 18276:2017)
Ta dokument določa zahteve za razvrstitev cevnih strženskih elektrod s plinsko zaščito ali brez nje, ki se uporabljajo za obločno varjenje visokotrdnih jekel v varjenem stanju ali stanju po varjenju s toplotno obdelavo z minimalno mejo prožnosti več kot 550 MPa ali minimalno natezno trdnostjo več kot 590 MPa. Posamezno cevno stržensko elektrodo je mogoče preskusiti in razvrstiti z različnimi zaščitnimi plini, če se uporablja več plinov.
Ta dokument je kombinirana specifikacija, ki določa razvrstitev po sistemu na osnovi meje prožnosti in povprečne energije udarca 47 J za čiste vare ali po sistemu na osnovi natezne trdnosti in povprečne energije udarca 27 J za čiste vare.
– Podtočke in preglednice z dodano črko »A« se uporabljajo samo za cevne strženske elektrode, ki so razvrščene po sistemu, ki temelji na meji prožnosti in povprečni energiji udarca 47 J za čiste vare, navedene v tem dokumentu.
– Podtočke in preglednice z dodano črko »A« se uporabljajo samo za cevne strženske elektrode, ki so razvrščene po sistemu, ki temelji na natezni trdnosti in povprečni energiji udarca 27 J za čiste vare, navedene v tem dokumentu.
– Podtočke in preglednice brez dodane črke »A« ali »B«
se uporabljajo za vse cevne strženske elektrode, ki so razvrščene v skladu s tem dokumentom.
Ugotovljeno je, da je mogoče delovne značilnosti cevnih strženskih elektrod spremeniti z uporabo
udarnega toka, toda za namene tega dokumenta se udarni tok ne uporablja za določanje razvrstitve žice.

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
