Specification and qualification of welding procedures for metallic materials — Welding procedure test — Part 13: Upset (resistance butt) and flash welding
This document specifies how a preliminary welding procedure specification (pWPS) is qualified by welding procedure tests. This document defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for all welding operations within the qualification of this document. Two classes of welding procedure tests are given in order to permit application to a wide range of welded fabrication. They are designated by classes A and B. In class A, the extent of testing is greater and the ranges of qualification are more restrictive than in class B. Procedure tests carried out to class A automatically qualify for class B requirements, but not vice-versa. When no class is specified in a contract or application standard, all the requirements of class A apply. NOTE Class B corresponds to level 1 and class A corresponds to level 2 in accordance with ISO 15614-1. This document applies to upset (resistance butt) welding and flash welding of any metallic materials in all product forms (e.g. with solid, tubular, flat or circular cross-sections). It covers the following resistance welding processes, as defined in ISO 4063:2023: — 24 – flash welding, using direct current or alternating current with various movement sequences, constant flashing and pulsed flashing; — 25 – resistance butt welding (upset welding), using direct current or alternating current with various current and pressure sequences.
Descriptif et qualification d'un mode opératoire de soudage pour les matériaux métalliques — Épreuve de qualification d'un mode opératoire de soudage — Partie 13: Soudage en bout par résistance pure et soudage par étincelage
Le présent document spécifie la manière dont un descriptif de mode opératoire de soudage préliminaire (DMOS-P) est qualifié par des épreuves de qualification de mode opératoire de soudage. Le présent document définit les conditions d'exécution des épreuves de qualification de modes opératoires de soudage et le domaine de validité des modes opératoires de soudage pour toutes les opérations de soudage relevant de la qualification du présent document. Deux classes d'épreuves de qualification de modes opératoires de soudage sont proposées afin de permettre une application à une large gamme de fabrications soudées. Elles sont désignées par les classes A et B. L'étendue des essais est plus grande dans la classe A, et les domaines de validité sont plus restrictifs que dans la classe B. Les épreuves de qualification de mode opératoire effectuées selon la classe A qualifient automatiquement les exigences de la classe B, mais pas l'inverse. Si aucune classe n'est spécifiée dans un contrat ou dans une norme d'application, toutes les exigences de la classe A s'appliquent. NOTE Selon l'ISO 15614-1, la classe B correspond au niveau 1, et la classe A correspond au niveau 2. Le présent document s'applique au soudage en bout par résistance pure et au soudage par étincelage de tout matériau métallique, sous toutes les formes de produits (par exemple des sections droites pleines ou tubulaires, plates ou circulaires). Il couvre les procédés de soudage par résistance suivants, tels que définis dans l’ISO 4063:2023: — 24 – soudage par étincelage en courant continu ou en courant alternatif avec diverses séquences de mouvement, étincelage continu et étincelage intermittent; — 25 – soudage en bout par résistance pure, en courant continu ou en courant alternatif avec diverses séquences de courant et d'effort.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

Introduction
It is intended that all new welding procedure qualifications be carried out in accordance with this
document from the date of its publication.
However, this document 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.
The primary purpose of welding procedure qualification is to demonstrate that the joining process
proposed for construction is capable of producing joints having the required mechanical properties for
the intended application.
Details of the ISO 15614 series are given in ISO 15607:2019, Annex A.
