Electron and laser-beam welded joints - Requirements and recommendations on quality levels for imperfections - Part 2: Aluminium, magnesium and their alloys and pure copper (ISO 13919-2:2021)
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.
Elektronen- und Laserstrahl-Schweißverbindungen - Anforderungen und Empfehlungen für Bewertungsgruppen für Unregelmäßigkeiten - Teil 2: Aluminium, Magnesium und ihre Legierungen und reines Kupfer (ISO 13919-2:2021)
Dieses Dokument gibt eine Anleitung für die Bewertung von Unregelmäßigkeiten in elektronen- und laserstrahlgeschweißten Verbindungen aus Aluminium, Magnesium und deren Legierungen und reinem Kupfer. Die drei Bewertungsgruppen sind so festgelegt, dass sie eine breite Anwendung in der schweißtechnischen Fertigung erlauben. Die Bewertungsgruppen beziehen sich auf die Fertigungsqualität und nicht auf die Gebrauchstauglichkeit der gefertigten Erzeugnisse.
Dieses Dokument ist anzuwenden für das Elektronen- und Laserstrahlschweißen von:
- Aluminium und dessen Legierungen;
- Magnesium und dessen Legierungen;
- reinem Kupfer (z. B. 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);
- allen Arten von Nähten, geschweißt mit oder ohne Zusatzdraht;
- Werkstoffdicken gleich oder größer 0,5 mm für das Elektronen- und Laserstrahlschweißen.
Wenn im geschweißten Erzeugnis entscheidende Abweichungen hinsichtlich der Nahtgeometrien und der in diesem Dokument beschriebenen Maße bestehen, ist der Umfang abzuschätzen, in dem die Bedingungen dieses Dokuments angewendet werden können.
ANMERKUNG Bei Rundschweißnähten kann eine niedrigere Bewertungsgruppe für die Auslaufzone festgelegt werden.
Metallurgische Aspekte, z. B. Korngröße, Härte, Wasserstoffkrankheit (reines Kupfer) sind in diesem Dokument nicht berücksichtigt.
Dieses Dokument kann direkt für die Sichtprüfung von Schweißungen benutzt werden. Es enthält keine Einzelheiten über die zu empfehlenden Verfahren zum Nachweis oder zur zerstörungsfreien Prüfung zur Größenbestimmung. Es gibt Schwierigkeiten in der Anwendung dieser Grenzen, um entsprechende Kriterien, die für zerstörungsfreie Prüfverfahren wie Ultraschall-, Durchstrahlungs- und Eindringprüfung anwendbar sind, aufzustellen. Deshalb können ergänzende Anforderungen für Untersuchungen, Über¬wachung und Prüfung erforderlich sein.
Assemblages soudés par faisceau d'électrons et par faisceau laser - Exigences et recommandations sur les niveaux de qualité des défauts - Partie 2: Aluminium, magnésium et leurs alliages et cuivre pur (ISO 13919-2:2021)
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.

Introduction
This document is intended to be used as a reference in drafting application codes and/or other application
standards. It contains a simplified selection of laser and electron beam welding imperfections based on
the designations given in ISO 6520-1.
Some imperfections described in ISO 6520-1 have been used directly and some have been grouped
together. The basic numerical referencing system from ISO 6520-1 has been used.
The purpose of this document is to define the dimensions of typical imperfections which can be
expected in normal fabrication. It can be used within a quality system for the production of welded
joints. It provides three sets of dimensional values from which a selection can be made for a particular
application. The quality level necessary in each case is defined by the application standard or the
responsible designer in conjunction with the manufacturer, user and/or other parties concerned. The
quality level is expected to be prescribed prior to the start of production, preferably at the enquiry or
order stage. For special purposes, additional details can be prescribed.
The quality levels given in this document provide basic reference data and are not specifically related
to any particular application. They refer to the types of welded joint in fabrication and not to the
complete product or component itself. Therefore, it is possible that different quality levels are applied
to individual welded joints in the same product or component.
It would normally be expected that, for a particular welded joint, the dimensional limits for
imperfections can all be covered by specifying one quality level. In some cases, it can be necessary to
specify different quality levels for different imperfections in the same welded joint.
The choice of quality level for any application is expected to take account of design considerations,
subsequent processing (e.g. surfacing), mode of stressing (e.g. static, dynamic), service conditions (e.g.
temperature, environment) and consequences of failure. Economic factors are also important and are
intended to include not only the cost of welding, but also of inspection, test and repair.
Although this document includes types of imperfection relevant to the beam welding processes given
in the Scope, only those which are applicable to the process and application in question need to be
considered.
Imperfections are quoted in terms of their actual dimensions, and their detection and evaluation
can require the use of one or more methods of non-destructive tes
