Specification and qualification of welding procedures for metallic materials - Welding procedure test - Part 12: Spot, seam and projection welding (ISO 15614-12:2014)

EN ISO 15614-12 specifies the tests which can be used for qualification of welding procedure specifications for spot, seam, and projection welding processes. This International Standard is part of the ISO 15614 series. Details of this series are given in ISO 15607, Annex A. This part of ISO 15614 defines the conditions for carrying out tests and the limits of validity of a qualified welding procedure for all practical welding operations covered by this part of ISO 15614. The tests required to qualify the procedure for a particular component/assembly depend on the performance and quality requirements of the component/assembly and shall be established before any qualification is undertaken. Tests shall be carried out in accordance with this part of ISO 15614 unless more severe tests are specified by the relevant application standard or contract when these shall apply. The acceptability of applying the principles of this part of ISO 15614 to other resistance welding processes should be established before any qualification is undertaken.

Anforderung und Qualifizierung von Schweißverfahren für metallische Werkstoffe - Schweißverfahrensprüfung - Teil 12: Widerstandspunkt-, Rollennaht- und Buckelschweißen (ISO 15614-12:2014)

Diese Norm legt fest, wie eine Schweißanweisung für Widerstandspunkt-, Rollennaht- und Buckel-Schweißprozesse durch Schweißverfahrensprüfungen qualifiziert wird.
Diese Norm ist Teil einer Normenreihe. ISO 15607, Anhang A, gibt Einzelheiten dieser Normenreihe wieder.
Diese Norm definiert die Bedingungen für die Durchführung der Prüfungen und die Grenzen der Gültigkeit eines qualifizierten Schweißverfahrens für alle praktischen schweißtechnischen Tätigkeiten innerhalb dieser Norm.
Die Prüfungen, die benötigt werden für die Qualifizierung eines Schweißverfahrens für ein bestimmtes Bauteil oder eine Baugruppe, hängen ab von den Anforderungen und Qualitätskriterien dieses Bauteils oder dieser Baugruppe und müssen festgelegt sein, bevor irgendeine Qualifizierung durchgeführt wird.
Die Prüfungen sind entsprechend dieser Norm durchzuführen, sofern nicht verschärfte Prüfungen von der Anwendernorm oder durch den Vertrag vorgegeben sind.
Die Eignung der verwendeten Grundsätze dieser Norm für andere Widerstands- sowie verwandte Schweißprozesse sollte feststehen, bevor irgendeine Qualifizierung durchgeführt wird.
ANMERKUNG Bestimmte Einsatz-, Werkstoff- oder Herstellungsbedingungen können umfassendere Prüfungen, als sie in dieser Norm festgelegt sind, erfordern.

Standard EN ISO 15614-12 določa preskuse, ki se uporabljajo za kvalifikacijo specifikacij varilnih postopkov za točkovno, kolutno in bradavično uporovno varjenje. Ta mednarodni standard je del skupine standardov ISO 15614. Podrobnosti te serije so navedene v dodatku A standarda ISO 15607. Ta del standarda ISO 15614 določa pogoje za izvajanje preskusov in omejitve veljavnosti kvalificiranih varilnih postopkov za vse praktične postopke varjenja, ki jih zajema ta del standarda ISO 15614. Preskusi, potrebni za kvalifikacijo postopka za določen sestavni del/sestav, so odvisni od zahtev glede učinkovitosti in kakovosti sestavnega dela/sestava in jih je treba določiti pred začetkom kvalifikacije. Preskusi se izvajajo v skladu s tem delom standarda ISO 15614, razen če so v ustreznem standardu o uporabi ali v pogodbi določeni težji preskusi. Sprejemljivost uporabe načel iz tega dela standarda ISO 15614 za druge postopke uporovnega varjenja naj bi določili pred začetkom kvalifikacije.

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).

Introduction
It is intended that all new welding procedure qualifications be carried out in accordance with this part
of ISO 15614 from the date of its issue.
However, this part of ISO 15614 does not invalidate previous welding procedure qualifications made
to other standards or specifications, provided the intent of its technical requirements is satisfied and
the previous welding procedure qualifications are relevant to the application and production work on
which they are to be employed.
Also, where additional tests have to be carried out to make the qualification technically equivalent, it
is necessary only to perform the additional tests on a test piece made in accordance with this part of
ISO 15614.
The various parts of ISO 15614 comprise, in their turn, a series of International Standards on welding,
details of which are given in ISO 15607, Annex A.
