This part of ISO 15614 is one of a series of standards, details of which are given in ISO 15607:2003, Annex A.
It specifies how a welding procedure specification for finishing welding of aluminium castings is qualified by welding procedure tests. It does not apply to repair welding.
For joint welding, ISO 15614-2 applies.
Arc welding of aluminium castings is covered by the following processes as defined in ISO 4063:
131 metal inert gas welding, MIG welding;
141 tungsten inert gas arc welding; TIG welding;
15 plasma arc welding.
Other fusion welding processes by agreement.
Shielding gases used in these processes are:
-- argon ISO 14175 I1;
-- helium ISO 14175 I2;
-- argon-helium mixture ISO 14175 I3.
Other shielding gases by agreement.
