20、ion 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 committe
21、e. 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. International Standards are drafted in accordance
22、with the rules given in the ISO/IEC Directives, 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 app
23、roval by at least 75 % of the member bodies casting a vote. 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. ISO 15614-4 was prepared by Technical Com
24、mittee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding. ISO 15614 consists of the following parts, under the general title Specification and qualification of welding procedures for metallic materials Welding procedure test: Part

BS EN ISO 15614-4:20051Specification and qualification of welding procedures for metallic materials Welding procedure test 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
29、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 f
30、ollowing 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
31、 mixture ISO 14175 I3. Other shielding gases by agreement. 2 Normative references The following referenced documents are indispensable for the application of this document.
