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.

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

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 6, Resistance welding and allied mechanical joining, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 121, Welding and allied processes, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This fourth edition cancels and replaces the third edition (ISO 15614-13:2021), which has been technically revised.

The main changes are as follows:

• petal test changed to bend test and bend test changed to three-point bend test;
• scope aligned with ISO 15614-1;
• Clauses 2, 3, 7 and 8 updated;
• clause numbering revised;
• Annex A and Annex B combined into a new Annex A.
• Table 1 modified;
• Clause 9 aligned with ISO 15614-1;

A list of all parts in the ISO 15614 series can be found on the ISO website.

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.

1 Scope

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.

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.
