28、(E)ForewordISO (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 a
29、 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 matte
30、rs of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This docu
31、ment was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).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 su
32、ch patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and doe

39、his part of ISO 15614 is one of a series of International Standards, the details of which are given in ISO 15607:2003, Annex A.All new welding procedure tests are intended to be carried out in accordance with this edition of ISO 15614-7 from the date of its publication. However, qualifications perfo
40、rmed in accordance with the previous editions of this part of ISO 15614 are still valid and it is not considered necessary to perform additional tests to fulfil its requirements for any application with reference to previous editions. Nevertheless, in order to comply with the requirements of the pre
41、sent edition it may be necessary to perform additional tests for previously qualified WPS.

42、s part of ISO 15614 specifies how a preliminary welding procedure specification for overlay welding is qualified by welding procedure tests.This part of ISO 15614 defines the conditions for execution of welding procedure tests and the range of qualification for welding procedures for all practical w
43、elding operations within the range of variables listed in Clause 8.This part of ISO 15614 applies to all welding processes suitable for overlay welding. In situations where qualification is carried out on a pre-production test piece, the qualification is performed in accordance with ISO 15613 except
44、 that, as far as possible, the testing is according to this part of ISO 15614. Building up and repair of parent metal is covered by ISO 15613 or ISO 15614-1.This edition of ISO 15614-7 is applicable to all new welding procedure qualification tests. It does not invalidate previous welding procedure t
45、ests made in accordance with previous editions of this part of ISO 15614. Where additional tests are required by the present edition, it is only necessary that those additional tests be carried out on a test piece made in accordance with the existing WPS and this part of ISO 15614.If buttering is us
46、ed for welding between dissimilar materials, the welding procedure is qualified in accordance with ISO 15614-1. This buttering may be required for weld combining different material structure or properties, e.g. joining martensitic steels or ferritic steels with austenitic steels.Additional tests may
47、 be required by application standards.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
