(Main)Welding consumables - Tubular cored electrodes for gas-shielded and non-gas-shielded metal arc welding of high strength steels - Classification (ISO 18276:2024)
Welding consumables - Tubular cored electrodes for gas-shielded and non-gas-shielded metal arc welding of high strength steels - Classification (ISO 18276:2024)
This document 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.
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.
— Subclauses and tables which carry the suffix “system 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 “system 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 “system A” or the suffix “system 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 18276:2024)
Dieses Dokument legt die Anforderungen 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 fest. 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.
- Unterabschnitte und Tabellen, gekennzeichnet durch ein nachgestelltes „System A“, sind nur für Fülldrahtelektroden anwendbar, die nach der Streckgrenze und einer durchschnittlichen Kerbschlagarbeit von 47 J des reinen Schweißgutes nach diesem Dokument eingeteilt werden.
- Unterabschnitte und Tabellen, gekennzeichnet durch ein nachgestelltes „System B“, sind nur für Fülldrahtelektroden anwendbar, die nach der Zugfestigkeit und einer durchschnittlichen Kerbschlagarbeit von 27 J des reinen Schweißgutes nach diesem Dokument eingeteilt werden.
- Unterabschnitte und Tabellen, die weder ein nachgestelltes „System A“ noch „System B“ enthalten, sind für alle nach diesem Dokument eingeteilten Fülldrahtelektroden anwendbar.
Es ist bekannt, dass die Schweißeigenschaften von Fülldrahtelektroden durch die Anwendung von pulsierendem Strom beeinflusst werden können, jedoch ist in diesem Dokument 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 18276:2024)
Le présent document 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.
Le présent document 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 du métal fondu hors dilution, soit sur la résistance à la traction et l'énergie de rupture moyenne de 27 J du métal fondu hors dilution.
— Les paragraphes et les tableaux qui portent le suffixe «système 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 du métal fondu hors dilution conformément au présent document.
— Les paragraphes et les tableaux qui portent le suffixe « système 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 du métal fondu hors dilution conformément au présent document.
— Les paragraphes et les tableaux qui ne portent ni le suffixe «système A», ni le suffixe «système B», sont applicables à tous les fils-électrodes fourrés classifiés conformément au présent document.
Il est reconnu que les caractéristiques d’emploi des fils-électrodes fourrés 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.
