Description of 21/30427299 DC 2021

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.
