Introduction
All new welding procedure tests are to be in accordance with this standard from the date of its issue.

However, this standard does not invalidate previous welding procedure tests made to former national standards or
specifications.

Where additional tests have to 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.

1 Scope
This standard is part of a series of standards, details of this series are given in EN ISO 15607, Annex A.

This standard specifies how a welding procedure specification is qualified by welding procedure tests.

This standard defines the conditions for the execution of welding procedure tests and the range of qualification for
welding procedures for all practical welding operations within the range of variables listed in clause 8.

Tests shall be carried out in accordance with this standard. Additional tests may be required by application
standards.

This standard applies to the arc welding of titanium, zirconium and their alloys in all product forms.

Arc welding is covered by the following processes in accordance with EN ISO 4063.

131 - metal inert gas welding, MIG welding

141 - tungsten inert gas welding, TIG welding

15 – plasma arc welding

The principles of this standard may be applied to other fusion welding processes.

7 Examination and testing

7.1 Extent of testing

Testing includes both non-destructive testing (NDT) and destructive testing which shall be in accordance with the
requirements of table 1.

An application standard may specify additional tests, e.g. :

 longitudinal weld tensile test ;

 all weld metal bend test ;

 hardness test

 impact test
 Page 11
prEN ISO 15614-5:2002

 corrosion tests :

 chemical analysis.

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.

are relevant to the application an additional qualification shall also be held e.g. a butt weld qualification.

7.2 Location and taking of test specimens

Test specimens shall be taken in accordance with Figures 5, 6, 7 and 8.

Test specimens shall be taken after all non-destructive testing (NDT) has been carried out and which has passed
the relevant inspection criteria for the NDT method(s) used.

It is acceptable to take the test specimens from locations avoiding areas which have imperfections within the
acceptance limits for the NDT method(s) used.

7.3 Non-destructive testing

All non-destructive testing in accordance with 7.1 and Table 1 shall be carried out on the test pieces prior to cutting
of the test specimens. Any post-weld heat treatment that is specified shall be completed prior to non-destructive
testing.

Depending upon joint geometry, materials and the requirements for work, the NDT shall be carried out as required
in table 1 in accordance with EN 970 (visual examination), EN 1435 (radiographic testing), and EN 571-1
(penetrant testing).

7.4 Destructive testing

The extent of testing shall be as required by table 1.

7.4.1 Transverse tensile test

Specimens and testing for transverse tensile testing for butt joint shall be in accordance with EN 895.

For pipes > 50 mm outside diameter, the excess weld metal shall be removed on both faces to give the test
specimen a thickness equal to the wall thickness of the pipe.

For pipes ≤ 50 mm outside diameter, and when full section small diameter pipes are used, the excess weld metal
may be left undressed on the inside surface of the pipe.

The tensile strength of the test specimen shall not be less than the corresponding specified minimum value for the
parent metal unless otherwise specified prior to testing.

For dissimilar joints the tensile strength shall not be less than the minimum value specified for the parent material
having the lowest tensile strength.

7.4.2 Bend test

Specimens and testing for bend testing for butt joints shall be in accordance with EN 910.

For thicknesses <12 mm two root and two face bend test specimens shall be used. For thicknesses >12 mm four
side bend specimens are recommended instead of root and face bend tests.

For dissimilar metal joints or heterogeneous butt joint in plates, one root and one face longitudinal bend test
specimen may be used instead of four transverse bend tests.

The diameter of the former or the inner roller shall be 6 t except for group 51 when 4 t shall be used. The bending
angle shall be 180° for parent metal with elongation A > 20%. For parent metal with elongation A < 20% the
following formula shall apply:

d = (100ts)/A - ts

where

d is the diameter of the former or inner roller

ts is thickness of the bend test specimen

A is the minimum tensile elongation required by the material specification

The test specimens shall bend uniformly and the weld, HAZ and parent metal areas will each conform closely to the
radius of the forming tool. This will indicate that any gas pick-up during welding has not reduced the ductility of the
weld and that the welding has not adversely affected the formability of the parent metal.

During testing, the test specimens shall not reveal any one single flaw > 3 mm in any direction. Flaws appearing at
the corners of a test specimen during testing shall be ignored in the evaluation.
Page 16
prEN ISO 15614-5:2002

7.4.3 Macro/micro-examination

The test specimen shall be prepared and examined in accordance with EN 1321 on one side to clearly reveal the
fusion line, the HAZ and the build up of the runs.

The macro-examination shall include unaffected parent metal and shall be recorded by at least one macro-
reproduction per procedure test.

The acceptance levels stated in 7.5 shall apply.

Care should be taken when etching alloys to provide crack like indications.

7.5 Acceptance levels

A welding procedure is qualified if the imperfections in the test piece are within the specified limits of quality level B
in prEN ISO 5817 except for imperfection types as follows : excess weld metal, excess convexity, excess throat
thickness and excessive penetration, for which quality level C shall apply.

NOTE The correlation between the quality levels of prEN ISO 5817 and the acceptance levels of the different NDT
techniques are given in EN 12062.

7.6 Coloration

Accepted colours on the weld metal surface: silver and straw. A narrow band of intensive colours close to the limits
of the gas shielding is acceptable. Darker brown, purple and blue colours and grey or flaky white are not acceptable.

7.7 Re-testing

If the test piece fails to comply with any of the requirements for visual examination or NDT specified in 7.5, one
further test piece shall be welded and subjected to the same examination. If this additional test piece does not
comply with the requirements, the welding procedure test has failed.

If any test specimens fails to comply with the requirements for destructive testing in accordance with 7.4 but only
due to weld imperfections, two further test specimens shall be obtained for each one that failed. The additional test
specimens can be taken from the same test piece if there is sufficient material available or from a new test piece.
Each additional test specimen shall be subjected to the same tests as the initial test specimen that failed. If either
of the additional test specimens does not comply with the requirements, the welding procedure test has failed.

If a tensile test specimen fails to meet the requirements of 7.4.1, two further test specimens shall be obtained for
each one that failed. Both shall satisfy the requirements of clause 7.4.1.

8 Range of qualification

8.1 General

Each of the conditions given in clause 8 of this standard shall be met in order to comply with this standard.

Changes outside of the ranges specified shall require a new welding procedure test.

8.2 Related to the manufacturer

A qualification of a pWPS by a welding procedure test according to this standard obtained by a manufacturer is
valid for welding in workshops or sites under the same technical and quality control of the manufacturer.

Welding is under the same technical and quality control when the manufacturer who performed the welding
procedure test retains complete responsibility for all welding carried out to it.
 Page 17
prEN ISO 15614-5:2002

8.3 Related to the parent material

8.3.1 Parent material grouping

In order to minimise the number of welding procedure tests, titanium, zirconium and their alloys are grouped
according to CR ISO/TR 15608.

Separate welding procedure qualifications are required for each parent material or parent material combinations not
covered by the grouping system.

If one parent material belongs to two groups or sub-groups, then it shall always be classified in the lower group or
sub-group.

NOTE Minor compositional differences between similar grades arising from the use of national standards do not need re-
qualification.

8.3.1.1 Titanium

The ranges of qualification are given in table 2.

8.3.1.2 Zirconium

The ranges of qualification are given in table 3.

8.3.2 Parent material thickness and pipe diameter

8.3.2.1 General

For single process qualification the thickness, t, shall have the following meanings :

a) For a butt joint :

the parent material thickness.

b) For a fillet weld :

the parent material thicknesses. For each thickness range qualified as in Table 4 there is also an associated
range of qualification for throat thicknesses, a, for single run fillet welds as given in 8.3.2.3.

c) For a set-on branch connection :

the parent material thicknesses.

d) For a set-in or set-through branch connection :

the parent material thicknesses.

e) For a T-joint in plate with full penetration:

the parent material thickness

For multi process procedures, the deposited metal thickness of each process shall be used as a basis for the range
of qualification for the individual welding process.

8.3.2.2 Range of qualification for butt joints, T- joints and branch connections

The qualification of a welding procedure test on thickness t shall include qualification for thickness in the following
ranges given in Table 4.

For multi process procedures, the deposited metal thickness of each process shall be used
as a basis for the range of approval for the individual welding process.
b
For fillet welds and branch connections, the range of qualification shall be applied to both
parent materials independently.

prEN ISO 15614-5:2002

8.3.2.3 Range of qualification for throat thickness of single run fillet welds

In addition to the requirements of Table 4, the range of qualification of the throat thickness “a” shall be “0,75a” to
“1,5a”.

Where a fillet weld is qualified by means of a butt weld test, the throat thickness range qualified shall be based on
the thickness of the deposited weld metal.

8.3.2.4 Range of qualification for the diameter of pipes and branch connections

The qualification of a welding procedure test on diameter D shall include qualification for diameters in the following
ranges given in Table 5.

Qualification given for plates also covers pipes when the outside diameter is > 500 mm or when the diameter is >
150 mm welded in the PA or PC rotated position.

D ≤ 25 0,5D to 2D

D > 25 ≥ 0,5D (25 mm min)

a
D is the outside diameter of the pipe or outside diameter of the branch
pipe.

8.3.3 Angle of branch connection

A welding procedure test carried out on a branch connection with angle α shall qualify all branch angles α1 in the
range of α ≤ α1 ≤ 90°.

8.4 Common to all welding procedures

8.4.1 Welding process

Each degree of mechanization shall be qualified independently (manual, partly mechanized, fully mechanized and
automatic).

The qualification is only valid for the welding process(es) used in the welding procedure test.

For multi-process procedures the welding procedure qualification may be carried out with separate welding
procedure tests for each welding process. It is also possible to make the welding procedure test as a multi-process
procedure test. The qualification of such a test is only valid for the process sequence carried out during the multi-
process procedure test.

NOTE It is not allowed to use a multi-process procedure test to qualify any single process unless the testing carried out on
the process conforms to this standard.

8.4.2 Welding positions

Welding of a test in any one position (pipe or plate) qualifies for welding in all positions (pipe or plate)except for PG
and J-L045 where a separate welding procedure is required.
Page 20
prEN ISO 15614-5:2002

8.4.3 Type of joint / weld

The range of qualification for the type of welded joints is as used in the welding procedure test subject to limitations
given in other clauses (e.g. diameter, thickness) and additionally:

given process.

8.4.4 Filler metal, designation

Filler materials cover other filler materials as long as they have equivalent mechanical properties , same nominal
composition according to the designation in the appropriate European standard for the filler material concerned.

8.4.5 Type of current

The qualification is given for the type of current (alternating current (AC), direct current (DC), pulsed current) and
polarity used in the welding procedure test.

8.4.6 Interpass temperature

The upper limit of qualification is the highest interpass temperature reached in the welding procedure test.

8.4.7 Post-weld heat treatment

Addition or deletion of post-weld heat treatment is not permitted.

The temperature range validated is the holding temperature used in the welding procedure test ± 20oC unless
otherwise specified. Where required, heating rates, cooling rates and holding time shall be related to the product.

8.4.8 Backing gas

Welding without backing gas qualifies for welding with backing gas, but not vice versa.

8.4.9 Welding in a chamber

Welding outside a chamber qualifies for welding in a chamber, but not vice versa.

8.5 Specific to processes

8.5.1 Process 131

8.5.1.1 The qualification given to the shielding, trailing and backing gas are restricted to the symbol of the gas
according to EN 439. Shielding gases not covered by EN 439 are restricted to the nominal composition used in the
test.

8.5.1.2 The qualification given is restricted to the wire system used in the welding procedure test (e.g. single-wire
or multiple-wire system

8.5.1.3 For solid wires, the qualification using short circuiting transfer (dip) qualifies only short circuiting transfer
(dip). Qualification using spray or globular transfer qualifies both spray and globular transfer.

8.5.2 Process 141

8.5.2.1 The qualification given to the shielding, trailing and backing gas are restricted to the symbol of the gas
according to EN 439. Shielding gases not covered by EN 439 are restricted to the nominal composition used in the
test.

8.5.2.2 Welding with filler material does not qualify for welding without filler material or vice versa.

8.5.3 Process 15

8.5.3.1 The qualification given is restricted to the plasma gas composition used in the welding procedure test.

8.5.3.2 The qualification given to the shielding, trailing and backing gas are restricted to the symbol of the gas
according to EN 439. Shielding gases not covered by EN 439 are restricted to the nominal composition used in the
test.

8.5.3.3 Welding with filler material does not qualify for welding without filler material or vice versa.

9 Welding procedure qualification record (WPQR)

The welding procedure qualification record (WPQR) is a statement of the results of assessing each test piece
including re-tests. The relevant items listed for the WPS in prEN ISO 15609-1 shall be included, together with
details of any features that would be rejectable by the requirements of clause 7. If no rejectable features or
unacceptable test results are found, a WPQR detailing the welding procedure test piece results is qualified and
shall be signed and dated by the examiner or examining body.

A WPQR format shall be used to record details for the welding procedure and the test results, in order to facilitate
uniform presentation and assessment of the data.

An example of WPQR-format is shown in Annex A.
