Welding - Methods for assessing imperfections in metallic structures

This Technical Report provides guidance on the selection and application of methods for assessing the significance of imperfections in all types of structures and components. The guidance is primarily tailored to welded structures and components in steel or aluminium alloys. Some of the methods may also be applied for other types of metals and for non-welded structures and components.

Schweißen - Verfahren zur Beurteilung von Unregelmäßigkeiten bei metallischen Bauteilen

Dieser Technische Bericht liefert einen Leitfaden für die Auswahl und Anwendung von Verfahren zur Beurteilung der Bedeutung vor Unregelmäßigkeiten für alle Arten von Bauwerken und -teilen. Der Leitfaden ist ursprünglich auf geschweißte Bauwerke und -teile aus Stahl- oder Aluminiumlegierungen zugeschnitten. Einige der Verfahren können auch für andere Werkstoffarten und für nicht geschweißte Bauwerke und -teile angewendet werden.

Soudage - Méthodes d'évaluation des défauts dans les constructions métalliques

Le présent Rapport technique fournit des lignes directrices pour le choix et l�application de méthodes
permettant l�évaluation de la signification des défauts dans tous les types de constructions et de composants.
Les lignes directrices sont essentiellement destinées aux constructions et composants soudés en acier et en
alliages d�aluminium. Certaines des méthodes peuvent également être appliquées à d�autres types de métaux
ainsi que pour des constructions et des composants non soudés.

Introduction
European provisions for assessing imperfections in metallic structures are needed to meet the requirements of
industry. The technology is being applied by many industries for materials selection, design and fabrication
and in-service assessment using existing methods. Engineering Critical Assessment (ECA) methods for the
assessment of imperfections have received further support by the EC directive 97/23/EC concerning pressure
equipment (PED) which permits such methods as an alternative to conventional methods.
The present Technical Report gives guidance to the application of BS 7910 and the European SINTAP Report.
Some further documents are also mentioned.
Experience from the application should, in a few years, provide enhanced technology in the subject and
eventually permit standardisation at the European level.
Conventional design procedures involve application of mathematical models such as the theory of elasticity.
Actions are described by characteristics such as stress and strain. Resista
