Introduction
The primary purpose of welding procedure qualification is to demonstrate that the joining process
proposed for construction is capable of producing joints having the required mechanical properties for
the intended application.
All new welding procedure tests are to be carried out in accordance with this document from the date
of this issue.
However, this document does not invalidate previous welding procedure tests made to former standards
or specifications or previous issues of this document.
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
document.

1 Scope
This document specifies how a preliminary welding procedure specification is qualified by welding
procedure tests.
This document applies to production welding, repair welding and build-up welding.
This document 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 qualification of this
document.
This document applies to the arc welding of wrought and cast aluminium and its alloys. In this document
the term aluminium stands for aluminium and for aluminium alloys.
This document does not apply to finishing welding of aluminium castings which is dealt by ISO 15614-4.
Arc welding of aluminium is covered by the following welding processes in accordance with ISO 4063:
131 — MIG welding with solid wire electrode;
141 — TIG welding with solid filler material (wire/rod);
142 — Autogenous TIG welding;
15 — plasma arc welding.
NOTE Specific service, material or manufacturing conditions may require more comprehensive testing than
is specified by this document (see 7.1).
The principles of this document may be applied to other fusion welding processes.

For all test pieces except branch connections (see Figure 4) and T-joints (and T-joints (T-butt weld or
fillet weld; see Figure 3), the material thickness, t, and the diameter, D, shall be the same for both plates
and pipes on the required length of the test piece to be welded. If required by the application standard,

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;
— weld metal bend test or special weld metal bend test to measure elongation;
— tensile test for the determination of the 0,2 % proof strength and/or elongation;
— chemical analysis;
— cruciform test.
NOTE Specific service, material or manufacturing conditions may require more comprehensive testing than
is specified by this document in order to gain more information and to avoid repeating the welding procedure
test at a later date just to obtain additional test data.
