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 à l'aide de procédés appropriés de soudage à l'arc et de rechargement sous laitier avec électrode en feuillard.
Elle est applicable en général à 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 à la corrosion du placage dépend de nombreux facteurs ; elle n'entre pas dans le cadre de la présente norme.

Overview

EN 1011-5:2003 (CEN) - Welding - Recommendations for welding of metallic materials - Part 5: Welding of clad steel - provides practical guidance and common requirements for seam closing by overlay welding of clad steel / base metal joints. The standard applies to arc welding processes and electroslag strip cladding and covers welding of cladding deposits and the transition zones between parent metal and cladding. It does not cover some non‑ferrous claddings (for example titanium, tantalum, zirconium and their alloys). Mechanical design, corrosion performance criteria and specific acceptance criteria are addressed in the relevant application standards rather than in this document.

Key topics and technical requirements

  • Materials: Definitions and considerations for clad steels, parent metal and cladding materials (stainless steels, nickel alloys, copper alloys, cobalt alloys).
  • Welding processes: Recommendations for suitable arc welding processes and electroslag strip cladding; advice on single‑side and two‑side welding techniques.
  • Joint preparation: Guidance referencing EN ISO 9692-4 for joint geometry and preparation; mechanical removal of thermally damaged zones after cutting.
  • Welding consumables: Selection criteria to ensure compatibility with both cladding and parent metal; consideration of dilution and alloy loss/gain (effects on chemical composition and ferrite number).
  • Dilution control: Emphasis on keeping dilution low while ensuring adequate penetration; methods to account for alloying changes between layers.
  • Welding procedure specification and qualification: Requirements to follow prEN ISO 15609-1, prEN ISO 15607 and prEN ISO 15614-1 for procedure documentation and qualification.
  • Preheat, interpass and PWHT: Measured according to EN ISO 13916; PWHT must consider both cladding and parent metal.
  • Back shielding and contamination control: Use of back shielding gas (EN 439) for single‑side work and strict cleanliness to maintain corrosion resistance.
  • Post‑weld cleaning and repair: Methods include brushing (stainless bristles), blasting (glass, stainless shot), pickling where required; special care to avoid formation of brittle phases in transition zones.
  • Quality and testing: Reference to prEN ISO 5817 for imperfection acceptance levels and use of ferrite number measurement methods when specified.

Applications and users

Practical applications include repair and fabrication of cladded components such as chemical process vessels, piping, heat exchangers and erosion/corrosion‑resistant linings. Typical users:

  • Welding engineers and procedure writers
  • Fabricators and welding supervisors
  • Quality control/inspection personnel
  • Materials engineers and designers specifying cladded constructions
  • Specifiers preparing welding and repair instructions
