21、ember 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, governm

22、ental 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Dir

23、ectives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bo

30、 Part 4: Finishing welding of aluminium castings 1 Scope 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 tes

31、ts. 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 fus

32、ion 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. 2 Normative references The following referenced documents are indispensable for the application of this doc
