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.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

ISO 13919-2:2021(E)
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 testing. The detection and sizing of

imperfections are dependent on the inspection methods and the extent of testing specified in the

application standard or contract.

This document does not address the methods used for the detection of imperfections.

The values given for imperfections are for welds produced using normal welding practice. More

stringent requirements as stated in quality level B can include additional manufacturing processes, e.g.

grinding, dressing.
