20、s held by DS, in collaboration with Technical Committee ISO/TC 44 “Welding and allied processes“. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2002, and conflicting national standards

21、 shall be withdrawn at the latest by September 2002. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informativ

22、e annex ZB, which is an integral part of this standard. Annexes A and ZB are informative. The annex ZA is normative. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czec

23、h Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 3 EN IS0 15614-112002 Introduction Qualification of welding procedures serves to demonstrate that production operations

24、 fully comply with the agreed welding procedure including preliminary and subsequent treatment. Before a particular welding procedure is used in a production operation, the manufacturer should determine and document the suitability of the Welding Procedure Specification (WPS) to produce a weld of th

25、e required quality. To date the suitability of welding procedures has been established for weldments as part of the quality assurance activity. Until now, establishing the suitability of welding procedures by weld procedure testing was carried out and documented only for weldments involving safety a

26、nd the public interest. The European harmonisation of the provision for welding procedure tests is currently being sought by means of European Standards. In this way greater confidence will be generated for the customer by the manufacturer. The proofs also serve as the basis for the mutual recogniti

27、on of performance reached by the relevant authorities. In this standard, the term “welding procedure“ comprises all the activities which influence the welding result, such as preparation, welding parameters, post treatment and reworking. 4 EN IS0 15614-112002 1 Scope This European Standard specifies

28、 how a welding procedure specification for electron or laser beam welding is qualified by a welding procedure test. This standard is a part of a series of standards, details of this series are given in prEN IS0 15607, annex A. It defines the conditions for the execution of welding procedure qualific

29、ation tests and the limits of validity of a qualified welding procedure for all practical welding operations within the range of variables listed in clause 8. Tests shall be carried out in accordance with this standard together with additional tests when specified. This standard applies to metallic

30、materials, irrespective of the shape of the parts, their thicknesses, manufacturing method (rolling, forging, casting, sintering, etc.) and their heat treatment. It covers unlimitedly the production of new parts and repair work. 2 Normative references This European Standard incorporates by dated or

31、undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only w

39、procedure specification (WPS) A pWPS (preliminary welding procedure specification) shall be prepared in accordance with prEN IS0 15609-3 for electron beam welding and prEN IS0 15609-4 for laser beam welding. It shall specify the tolerances for all the relevant parameters. A WPS shall be classified a

40、s pWPS until it is qualified in accordance with this standard. The welding procedure specification (WPS) shall give details on how a welding operation is to be performed, including tacking and fixturing. 5 Welding procedure test The manufacture and testing of test pieces shall be in accordance with

41、clauses 6 and 7 of this standard. In order to take into account the service performance needs of the products, the qualification may be made according to any of the acceptance levels B, C or D as defined in EN IS0 13919-1 for steels or in prEN IS0 13919- 2 for aluminium and its alloys. The quality l

42、evel necessary in each case should be specified by the application standard or the responsible designer. 6 Test piece 6.1 General The assembly to which the electron or laser beam welding procedure applies in production may be represented by one or more standardized test pieces as defined in 6.2. 6.2

43、 Shape and dimensions of test pieces The test pieces shall be of sufficient size to ensure an adequate heat distribution and for the application of non- destructive and/or destructive tests. The test piece shall be designed to represent, as far as possible, the component and joint geometry and shall

44、 be specified. One or more additional test pieces or a longer test piece than the minimum size, may be used in order to allow for extra and/or for re-testing specimens, according to 7.5. For plate material, the principal direction of rolling shall be marked on the test piece, if requested by the app

45、lication standard or the specification. The thickness and/or pipe outside diameter of the test pieces shall be selected in accordance with 8.5.2.1 to 8.5.2.2. Unless otherwise specified, the shape and minimum dimensions of the test piece shall be as defined hereafter. Nonetheless, the length of the

46、test piece shall be such as to permit the appropriate number of test specimens (as given in Tables 1 to Table 3) to be prepared. 6 EN IS0 15614-112002 6.2.1 Linear butt weld The test piece shall be in accordance with Figure 1 a P a Key 1 Edae DreDaration and fit-up as detailed in the preliminary Wel

47、ding Procedure Specification (pWPS) a = 3 x 7; minimum value 150 mm b = 6 x t ; minimum value 300 mm t = thickness of the thinner material in a dissimilar thickness joint Figure 1 - Test piece for a linear butt weld 7 EN IS0 15614-112002 6.2.2 Circular butt weld The test piece shall be in accordance

48、 with Figures 2 a) or 2 b). When small pipe diameters are used, several test pieces may be necessary. In cases where the diameter, D, of the part is greater than 150 mm and D 20 t, the qualification of the procedure may be achieved by welding a linear test piece. The test shall be designed to incorp

49、orate the weld overlap and slope down areas.
