18、 is a worldwide federation 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 repre
19、sented on that committee. 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
20、 drafted in accordance 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 Internationa
21、l Standard requires approval 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.

29、 of the SABS .INTERNATIONAL STANDARD ISO 15614-7:2007(E) ISO 2007 All rights reserved 1Specification and qualification of welding procedures for metallic materials Welding procedure test Part 7: Overlay welding 1 Scope This part of ISO 15614 specifies how a preliminary welding procedure specificatio
30、n for overlay welding is qualified by welding procedure tests. This part of ISO 15614 defines the conditions for carrying out 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. Additiona
31、l tests may be required by application standards. This part of ISO 15614 applies to all welding processes suitable for overlay welding. This part of ISO 15614 is applicable to all new welding procedures. However, it does not invalidate previous welding procedure tests made to former national standar
32、ds or specifications. Where additional tests are carried out to make the qualification technically equivalent, they are only done on a test piece made in accordance with this part of ISO 15614. This part of ISO 15614 does not apply to overlay welding where cracks are intentionally produced (e.g. spe
