Welding - Laser-arc hybrid welding of steels, nickel and nickel alloys - Quality levels for imperfections (ISO 12932:2013)
ISO 12932:2013 specifies quality levels of imperfections in laser-arc hybrid welded joints for all types of steel, nickel and its alloys. It applies to material thickness ≥0,5 mm.
Three quality levels are given in order to permit application for a wide range of welded fabrication. They are designated by B, C and D. Quality level B corresponds to the highest requirement on the finished weld. The quality levels refer to production quality and not to the fitness-for-purpose of the product manufactured.
Schweißen - Laserstrahl-Lichtbogen-Hybridschweißen von Stählen, Nickel und Nickellegierungen - Bewertungsgruppen für Unregelmäßigkeiten (ISO 12932:2013)
Diese Internationale Norm enthält Bewertungsgruppen von Unregelmäßigkeiten in Laserstrahl-Lichtbogen-Hybridschweißverbindungen für alle Arten von Stahl, Nickel und seinen Legierungen.
Die drei Bewertungsgruppen sind so angelegt, dass sie eine breite Anwendung in der schweißtechnischen Fertigung erlauben. Sie werden bezeichnet durch Kennbuchstaben B, C und D. Die Bewertungsgruppe B entspricht den höchsten Anforderungen an die Schweißnaht. Die Bewertungsgruppen beziehen sich auf die Fertigungsqualität und nicht auf die Gebrauchstauglichkeit (siehe 3.2) des gefertigten Erzeugnisses.
Soudage - Soudage hybride laser-arc des aciers, du nickel et des alliages de nickel - Niveaux de qualité par rapport aux défauts (ISO 12932:2013)
L'ISO 12932:2013 fournit des niveaux de qualité par rapport aux défauts dans les assemblages réalisés par soudage hybride laser-arc sur tous types d'acier, de nickel et ses alliages. Elle s'applique à des épaisseurs de matériau supérieures à 0,5 mm.
Trois niveaux de qualité sont donnés dans le but de permettre son application à une large gamme de fabrications soudées. Ils sont désignés par B, C et D. Le niveau de qualité B correspond à l'exigence la plus élevée pour la soudure terminée. Les niveaux de qualité se rapportent à la qualité de la fabrication et non à l'aptitude à l'emploi du produit fini.
Varjenje - Obločno hibridno varjenje jekel, niklja in nikljevih zlitin z laserjem - Stopnje sprejemljivosti napak (ISO 12932:2013)
Ta mednarodni standard določa stopnje sprejemljivosti napak pri spojih, varjenih z obločnim hibridnim varjenjem z laserjem, za vse vrste jekla, niklja in nikljevih zlitin. Za uporabo širokega nabora varjenih izdelkov so določene tri stopnje sprejemljivosti. Označene so s simboli B, C in D. Stopnja sprejemljivosti B ustreza najvišjim zahtevam za končne izdelke po varjenju. Stopnje sprejemljivosti zadevajo kakovost izdelave in ne primernosti za namen (glejte razdelek 3.2) izdelanega izdelka.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
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.
ISO 12932 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 10, Unification of requirements in the field of metal welding.
Requests for official interpretation of any aspect of this International Standard should be directed to the
secretariat of ISO/TC 44/SC 10 via your national standards body. A complete listing of these bodies can

Introduction
This International Standard is intended to be used as a reference in drafting application codes and/or
other application standards. It contains a simplified selection of laser-arc hybrid 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 International Standard 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 International Standard 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. It is possible, therefore, 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 International Standard includes types of imperfection relevant to the laser-arc hybrid
welding processes given in Clause 1, 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
may 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 International Standard does not address the methods used for the detection of imperfections. However,
ISO 17635 contains a correlation between the quality level and acceptance level for different NDT methods.
This International Standard 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.
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,
TIG dressing.
