Electron and laser-beam welded joints — Requirements and recommendations on quality levels for imperfections — Part 2: Aluminium, magnesium and their alloys and pure copper

Edition date: 2021-01-26
In Force
Available languages: English, French
Summary:

This document gives guidance on levels of imperfections in electron and laser beam welded joints in aluminium, magnesium and their alloys and pure copper. Three levels are given in such a way as to permit application for a wide range of welded fabrications. The levels refer to production quality and not to the fitness-for-purpose of the product manufactured.

This document applies to electron and laser beam welding of:

— aluminium and its alloys;

— magnesium and its alloys;

— pure copper (e.g. Cu-ETP1 CW003A, Cu-ETP CW004A, Cu-FRHC CW005A, Cu-FRTP CW006A, Cu-OF1 CW007A, Cu-OF CW008A, Cu-OFE CW009A, Cu-PHC CW020A, Cu-HCP CW021A, Cu-PHCE CW022A, Cu-DLP CW023A, Cu-DHP CW024A);

— all types of welds welded with or without additional filler wire;

— materials equal to or above 0,5 mm thickness for electron and laser beam welding.

When significant deviations from the joint geometries and dimensions stated in this document are present in the welded product, it is necessary to evaluate to what extent the provisions of this document can apply.

NOTE For circular welds, a lower quality level can be specified for the fade-out zone.

Metallurgical aspects, e.g. grain size, hardness, hydrogen embrittlement (pure copper) are not covered by this document.

This document is directly applicable to visual examination of welds and does not include details of recommended methods of detection or sizing by other non-destructive means. There are difficulties in using these limits to establish appropriate criteria applicable to non-destructive testing methods, such as ultrasonic, radiographic and penetrant testing, and they can need to be supplemented by requirements for inspection, examination and testing.



Le présent document constitue un guide d'évaluation des niveaux des défauts dans les assemblages en aluminium en magnésium et leurs alliages et en cuivre pur, soudés par faisceau d'électrons et par faisceau laser. Elle prévoit trois niveaux, de façon à être applicable à une large gamme de fabrications soudées. Ces niveaux se rapportent à la qualité en production et non à l'aptitude à l'emploi du produit fabriqué.

Le présent document concerne le soudage par faisceau d'électrons et par faisceau laser dans les applications suivantes:

— aluminium et ses alliages;

— magnésium et ses alliages;

— cuivre pur (par exemple: Cu-ETP1 CW003A, Cu-ETP CW004A, Cu-FRHC CW005A, Cu-FRTP CW006A, Cu-OF1 CW007A, Cu-OF CW008A, Cu-OFE CW009A, Cu-PHC CW020A, Cu-HCP CW021A, Cu-PHCE CW022A, Cu-DLP CW023A, Cu-DHP CW024A);

— tous types de soudures réalisées avec ou sans fil d'apport;

— matériaux d'épaisseur supérieure ou égale à 0,5 mm en soudage par faisceau d'électrons et par faisceau laser.

Pour tout écart significatif dans la géométrie ou les dimensions de l'assemblage décrites dans le présent document apparaissant sur le produit soudé, il est nécessaire d'évaluer dans quelle mesure les dispositions de la présente norme restent applicables.

NOTE Pour les soudures circulaires, un niveau de qualité inférieur peut être spécifié, pour la zone d'évanouissement.

Le présent document ne traite pas des aspects métallurgiques tels que la grosseur de grain, la dureté ou la fragilisation par l'hydrogène (cuivre pur).

Le présent document est directement applicable à l'examen visuel des soudures et n'inclut pas de détails sur les méthodes recommandées de détection ou de dimensionnement par d'autres moyens non destructifs. Il est difficile d'utiliser ces limites pour établir des critères appropriés applicables aux méthodes d'essai non destructives, telles que les essais par ultrasons, par radiographie et par ressuage, et il peut être nécessaire de les compléter par des exigences en matière de contrôle, d'examen et d'essai.
