24、 2009 All rights reservedForeword 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 i

25、n a subject 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 Commis

26、sion (IEC) 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

27、 committees 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

28、 not be held responsible for identifying any or all such patent rights. ISO 15609-4 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding. This second edition cancels and replaces the first edition (

29、ISO 15609-4:2004), which has been technically revised.

32、elding 1 Scope This part of ISO 15609 specifies requirements for the content of the welding procedure specification (WPS) for laser beam welding processes, including overlay welding. It is not applicable to other processes for cladding (e.g. thermal spraying). This part of ISO 15609 is part of a ser

33、ies of standards, and details of this series are given in ISO 15607:2003, Annex A. Variables listed in this part of ISO 15609 are those influencing the quality and properties of the welded joint. The dimensions mentioned in this part of ISO 15609 influence the metallurgical and mechanical qualities,

34、 the geometry of the structural member and other important performance properties. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the

38、 at the end of the welding NOTE 1 Adapted from ISO/TR 25901:2007, definition 2.336. NOTE 2 The slope down region is the region on the workpiece in which the effects of slope down occur. It can consist of one or two of the following areas, depending on the selected welding mode. a) In full penetratio

39、n welding, it can consist of g127 a region where beam penetration is still complete, and g127 a region where penetration is partial or decreasing. b) In partial penetration welding, it can consist of g127 a region where penetration decreases continuously. 3.3 working distance g162beam weldingg178 di

41、 proper alignment until the final welds are made NOTE 1 Adapted from ISO/TR 25901:2007, definition 2.370. NOTE 2 This can be produced by a continuous or discontinuous pass with partial penetration. 3.5 pass run single operation of welding that is part of the production of a completed weld NOTE 1 Ada

42、pted from ISO/TR 25901:2007, definition 2.312. NOTE 2 The term “pass” is commonly used in beam welding. 3.6 cosmetic pass pass for superficial remelting of the weld in order to enhance appearance NOTE 1 Adapted from ISO/TR 25901:2007, definition 2.75. NOTE 2 This pass can be performed with a defocus

Some manufacturers additionally prefer to prepare work instructions for each specific job as part of the detailed production planning. Information liste

49、d below is adequate for most welding operations. For some applications, it is necessary to supplement or reduce the list. The relevant information shall be specified in the WPS. Ranges and tolerances, according to the manufacturers experience, shall be specified when appropriate.
