9、 reserved iii Foreword 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
10、 for which 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)
11、on all matters 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
12、 are circulated 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 hel
13、d responsible for identifying any or all such patent rights. ISO 15609-3 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding,
14、in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This first edition cancels and replaces ISO 9956-10:1996 which has been technically revised. Throughout the text of this document, read “.this European Standard.” to mean “.this International Standard.”

This standard is part of a series of standar
26、ds, details of this series are given in EN ISO 15607:2003, annex A. Variables listed in this standard are those influencing the quality and properties of the welded joint. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated refe
27、rences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

29、and the following apply. 3.1 slope up controlled increase of the beam power at the beginning of welding 3.2 slope down controlled decrease of the beam power at the end of welding. The slope down region is the region on the workpiece in which the effects of slope down occur. It can consist of one or
30、two areas, depending on the selected welding mode: a) in full penetration welding: a region where beam penetration is still complete; a region where penetration is partial or decreasing. b) in partial penetration welding: a region where penetration decreases continuously.
