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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

DRAFT INTERNATIONAL STANDARD ISO/DIS 15614-4:2021(E)
Specification and qualification of welding procedures for
metallic materials — Welding procedure test —
Part 4:
Finishing welding of aluminium castings
1 Scope
This document is part of a series of standards, details of which are given in ISO 15607:2019, Annex A.
This document specifies how a welding procedure specification for finishing welding of aluminium
castings is qualified by welding procedure tests.
Arc welding of aluminium castings is performed by the following processes in accordance with
ISO 4063:
— 131 MIG welding with solid wire electrode
— 132 MIG welding with flux cored electrode
— 133 MIG welding with metal cored electrode
— 141 TIG welding with solid filler material (wire/rod)
— 142 Autogenous TIG welding
— 143 TIG welding with tubular cored filler material (wire/rod)
— 145 TIG welding using reducing gas and solid filler material (wire/rod)
— 146 TIG welding using reducing gas and tubular cored filler material (wire/rod)
— 15 plasma arc welding
The shielding gases used with these processes are:
— argon, ISO 14175 – I1
— helium, ISO 14175 – I2
— argon helium mixture, ISO 14175 – I3
The principles of this document can be applied to other welding processes and shielding gases.
This document is not applicable for repair welding or for welding of joints where ISO 15614-2 is to be
used.
