Welding - Recommendations for welding of metallic materials - Part 5: Welding of clad steel

This European standard specifies common instructions and requirements for the seam closing by overlay welding of clad steel/base metal joints.

Schweißen - Empfehlungen zum Schweißen metallischer Werkstoffe - Teil 5: Schweißen von plattierten Stählen

1 Anwendungsbereich
Diese Europäische Norm legt allgemeine Empfehlungen für das Schweißen von plattierten Stählen mit geeigneten Lichtbogenschweißverfahren sowie für das Bandplattieren durch Elektroschlackeschweißen fest.
Sie ist allgemein anwendbar auf alle plattierten Stähle und ist geeignet für alle Arten der Verarbeitung. Die Anwendungsnorm kann jedoch zusätzliche Bestimmungen enthalten.
Beispiele für die Nahtvorbereitung sind in prEN ISO 9692-4 gegeben.
Diese Norm umfasst das Schweißen von Schweißplattiergut sowie das Schweißen der Übergangszone(n) zwischen dem Grundwerkstoff und der Plattierung. Diese Übergangszonen sind Metallkombinationen von unlegierten Eisenwerkstoffen aus hochlegierten nichtrostenden oder nickellegierten Plattierungen oder anderen Nichteisenmetallen.
Plattierungen aus Nichteisenmetallen wie Titan, Tantal, Zirkonium und deren Legierungen werden in dieser Norm nicht erfasst.
Die mechanische und physikalische Ausführung der Nähte sind nicht Gegenstand dieser Norm. Prüfmethoden und Bewertungsgruppen sind nicht enthalten, da sie von den Betriebsbedingungen der Fertigung abhängen. Diese Einzelheiten sollten der Konstruktionsfestlegung entnommen werden.
Die Korrosionsbeständigkeit der Plattierung ist von vielen Faktoren abhängig und nicht Bestandteil dieser Norm.

Soudage - Recommendations pour le soudage des matériaux métalliques - Partie 5: Soudage des aciers plaqués

La présente Norme européenne donne des recommandations générales pour le soudage d'aciers plaqués a l'aide de procédés appropriés de soudage a l'arc et de rechargement sous laitier avec électrode en feuillard.
Elle est applicable en général a tous les aciers plaqués, et elle convient quel que soit le type de fabrication concerné, bien que la norme d'application puisse comporter des exigences supplémentaires.
Des exemples de préparations sont présentés dans le prEN ISO 9692-4.
Elle couvre l'exécution des rechargements par soudage ainsi que le soudage de la (ou des) zone(s) de transition entre le métal support et le placage. Ces zones de transition sont des combinaisons métalliques constituées du métal support ferreux non allié et de placages en aciers inoxydables fortement alliés ou d'alliages de nickel, ou de métaux non ferreux.
Les placages en métaux non ferreux tels que le titane, le tantale, le zirconium et leurs alliages ne sont pas couverts par la présente norme.
La conception mécanique et physique des assemblages n'est pas couverte par la présente norme. Les méthodes de contrôle et d'essai, ainsi que les niveaux d'acceptation ne sont pas décrits, car ils dépendent des conditions de service de la structure en acier plaqué. Il convient de rechercher ces détails dans les spécifications de conception.
La résistance a la corrosion du placage dépend de nombreux facteurs ; elle n'entre pas dans le cadre de la présente norme.

EN 1011-5:2003 (E)41 ScopeThis European Standard gives general recommendations for welding of clad steels by means of appropriate arcwelding processes and electroslag strip cladding.It is generally applicable to all clad steels and is appropriate regardless of the type of fabrication involved, althoughthe application standard may have additional requirements. Non-ferrous claddings, such as titanium, tantalum,zirconium and their alloys are not covered by this standard.Examples for joint preparation are given in EN ISO 9692-4.This standard covers welding of cladding deposits as well as welding of the transition zone(s), when existing,between parent metal and cladding. These transition zones are metal combinations of non-alloyed ferrous parentmetal with high alloyed stainless steels, nickel alloys or other non-ferrous metals.The mechanical and physical design of the joints is not covered by this standard. Methods of testing andacceptance levels are not included because they depend on the service conditions of the fabrication. These detailsshould be obtained from the design specification.The corrosion resistance of the cladding depends on many factors and is not a part of this standard.For general guidelines see EN 1011-1.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

EN 1011-5:2003 (E)53 Terms and definitionsFor the purposes of this European Standard, the following term and definition apply.3.1clad steelcombination of two or more dissimilar metals bonded inseparably together by different cladding processes4 Materials4.1 Clad steelsClad steels can be produced by several cladding processes such as:¾ hot roll cladding;¾ explosive welding;¾ surfacing by welding;¾ combined weld / hot roll cladding.The inseparable cladding (commonly t2 ³ 2 mm wall thickness), which will be in contact with the adjacent medium,is designed to meet requirements such as corrosion resistance, abrasion and/or heat resistance at different workingtemperatures.4.2 Parent metalThe parent metal is a weldable steel, commonly according to CR ISO 15608:2000 (group 1 to 6). The parent metalhas to provide the required strength and toughness to maintain mechanical integrity.4.3 CladdingCladding includes:¾ Stainless steels according to EN 10088-1;¾ Nickel and nickel alloys;¾ Copper and copper alloys;¾ Cobalt alloys (stellites).Cladding shall be capable of being joined by arc welding processes to the parent metals.The finished surface conditions of cladding particularly used in components for the chemical industry shouldguarantee an adequate corrosion resistance and other specified characteristics. For information on corrosionresistance of cladding see relevant application standards.5 Welding consumables for cladding depositsThe cladding deposit, including dilution with the cladding, shall be compatible with the cladding. Therefore,consumables should be selected with regard to the parent metal, to the cladding and the particular application. Theconsumables shall comply with the relevant standards and/or specifications.Where consumable inserts are used, they shall correspond with the relevant filler metal composition.SIST EN 1011-5:2003
