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.

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.
NOTE Specific service, material, or manufacturing conditions might require more comprehensive testing
than is specified by this Part of ISO 15614.
Such tests can include:
— method for fatigue testing for spot welded join
