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 15614-14 was prepared by Technical Committee ISO/TC 044, Welding and allied processes,
Subcommittee SC 10, Unification of requirements in the field of metal welding.

Introduction
All new welding procedure tests shall be carried out in accordance with this standard from the date of its
issue.
However, this International Standard does not invalidate previous welding procedure tests made to former
national standards or specifications.
Where additional tests shall be carried out to make the qualification technically equivalent, it is only necessary
to do the additional tests on a test piece which should be made in accordance with this standard.

3 Terms and definitions
For the purposes of this International Standard, the terms and definitions given in ISO 15607 and the following
apply.
3.1
hybrid welding
fusion processes of welding with a combination in the form of a combined melt pool and therewith a defined
clear combined process zone were termed “hybrid“ fusion processes of welding
NOTE Thus they are different to combinations of processes where exist at least two melt pools which are completely
separated by a solid component in the solidification phases. An example is given in Figure 1 by using a laser beam and
the additional energy source of an arc.

The welding and testing of test pieces shall be in accordance with Clauses 6 und 7.
The welding operator who undertakes the welding procedure test satisfactorily in accordance with this
standard shall be qualified for the appropriate range of qualification according to the regionally applicable
regulations (e.g. ISO 14732).
6 Test piece
6.1 General
The welded joint to which the welding procedure will relate in production shall be represented by making a

The length or number of test pieces shall be sufficient to allow all required tests to be carried out.
Additional test pieces, or longer test pieces than the minimum size, may be prepared in order to allow for extra
and/or for re-testing specimens (see 7.6). Application standards may require larger test pieces.
If required by the application standard, the direction of plate rolling shall be marked on the test piece when
impact tests are required to be taken in the Heat Affected Zone (HAZ).

The thickness and/or pipe outside diameter of the test pieces shall be selected in accordance with 8.3.2.1 to
8.3.2.3.
NOTE The word „pipe“, alone or in combination, is used to mean „pipe“, „tube“ or „hollow section“.

7.1 Extent of examination and testing
Testing includes both non-destructive testing and destructive testing which shall be in accordance with the
requirements of Table 1.
NOTE Specific service, material or manufacturing conditions may require more comprehensive testing than is
specified by this standard in order to gain more information and to avoid repeating the welding procedure test at a later
date just to obtain additional test data.
An application standard may specify additional tests, e.g.:
⎯ longitudinal weld tensile test;
⎯ all weld metal bend test;
⎯ corrosion tests;
⎯ chemical analysis;
⎯ micro examination;
