17、rvedForeword ISO (the International Organization for Standardization) 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
18、 a technical committee has been established has the right to be represented 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 mat
19、ters of electrotechnical standardization. International Standards are 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 circu
20、lated to the member bodies for voting. Publication as an International 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 responsi
21、ble for identifying any or all such patent rights. ISO 15614-10 was prepared by Technical Committee ISO/TC 44, Welding and allied processes. ISO 15614 consists of the following parts, under the general title Specification and qualification of welding procedures for metallic materials Welding procedu
22、re test: Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys Part 2: Arc welding of aluminium and its alloys Part 3: Arc welding of cast iron Part 4: Finishing welding of aluminium castings Part 5: Arc welding of titanium, zirconium and their alloys Part 6: Arc welding

25、he date of publication. This part of ISO 15614 does not invalidate previously qualified welding procedures in accordance with other standards or specifications, providing the technical requirements are satisfied and the previous qualifications are relevant to the application and production work on w
26、hich they are to be employed. Where additional tests have to be carried out to make the qualification technically equivalent, it is only necessary to do the additional tests in accordance with this part of ISO 15614. Requested for official interpretations of any aspect of this standard should be dir
