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

Introduction
Qualification of welding procedures serves to demonstrate that production operations fully comply
with the agreed welding procedure including preliminary and subsequent treatment.
Before a particular welding procedure is used in a production operation, the manufacturer should
determine and document the suitability of the Welding Procedure Specification (WPS) to produce a
weld of the required quality.

specified.
This document applies to metallic materials, irrespective of the shape of the parts, their thicknesses,
manufacturing method (rolling, forging, casting, sintering, etc.) and their heat treatment. It covers both

4 Preliminary welding procedure specifications (pWPS)
A pWPS (preliminary welding procedure specification) shall be prepared in accordance with
ISO 15609-3 for electron beam welding and ISO 15609-4 for laser beam welding. It shall specify the
tolerances for all the relevant parameters.
A WPS shall be classified as pWPS until it is qualified in accordance with this standard.
The welding procedure specification (WPS) shall give details on how a welding operation is to be
performed, including tacking and fixturing.
5 Welding procedure test
The manufacture and testing of test pieces shall be in accordance with Clauses 6 and 7 of this standard.
In order to take into account the service performance needs of the products, the qualification may
be made according to any of the acceptance levels B, C or D as defined in ISO 13919-1 for steels or in
ISO 13919- 2 for aluminium and its alloys.
The quality level necessary in each case should be specified by the application standard or the
responsible designer.
6 Test piece
6.1 General
The assembly to which the electron or laser beam welding procedure applies in production may be
represented by one or more standardized test pieces as defined in 6.2.

6.2 Shape and dimensions of test pieces
The test pieces shall be of sufficient size to ensure an adequate heat distribution and for the application
of non- destructive and/or destructive tests.
The test piece shall be designed to represent, as far as possible, the component and joint geometry and
shall be specified.
One or more additional test pieces or a longer test piece than the minimum size, may be used in order to
allow for extra and/or for re-testing specimens, according to 7.5.
For plate material, the principal direction of rolling shall be marked on the test piece, if requested by
the application standard or the specification.
The thickness and/or pipe outside diameter of the test pieces shall be selected in accordance with
8.5.2.1 to 8.5.2.2.
Unless otherwise specified, the shape and minimum dimensions of the test piece shall be as defined
hereafter. Nonetheless, the length of the test piece shall be such as to permit the appropriate number of
test specimens (as given in Table 1 to Table 3) to be prepared.
6.2.1 Linear butt weld
The test piece shall be in accordance with Figure 1.
6.2.2 Circular butt weld
The test piece shall be in accordance with Figures 2 a) or 2 b). When small pipe diameters are used,
several test pieces may be necessary.
In cases where the diameter, D, of the part is greater than 150 mm and D > 20 t, the qualification of the
procedure may be achieved by welding a linear test piece. The test shall be designed to incorporate the
weld overlap and slope down areas.
NOTE The word pipe is used to mean "pipe", "tube" or "hollow section".
