ISO 15614-5:2004 specifies how a welding procedure specification is qualified by welding procedure tests.
It 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.
It is intended that tests be carried out in accordance with this International Standard. Additional tests may be required by application standards.
ISO 15614-5:2004 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 International Standard may be applied to other fusion welding processes.
