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/foreword.html.
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, in accordance with
the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 15614-13:2012), which has been
technically revised.
The main changes are as follows:
— petal test was changed to bend test and bend test was changed to three-point bend test;
— Clauses 2 and 3 have been updated;
— Clauses 7 and 8 have been updated;
— Table 1 has been modified.
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 issue.
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.
Also, where additional tests need 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 document.
Details on the ISO 15614 series on welding are given in ISO 15607:2019, Annex A.

INTERNATIONAL STANDARD ISO 15614-13:2021(E)
Specification and qualification of welding procedures for
metallic materials — Welding procedure test —
Part 13:
Upset (resistance butt) and flash welding
1 Scope
This document specifies tests for the qualification of welding procedure specifications applicable to
upset (resistance butt) welding and flash welding of metallic materials, e.g. with solid, tubular, flat or
circular cross-section. Its basic principles can also be applied to other resistance welding processes
when this is stated in the specification.
This document defines the conditions for carrying out tests and the limits of validity of a qualified
welding procedure for all the practical welding operations that it covers.
It covers the following resistance welding processes, as defined in ISO 4063:
— 24 flash welding, using direct current or alternating current with various movement sequences,
constant flashing and pulsed flashing;
— 25 resistance upset welding, using direct current or alternating current with various pressure
sequences.
