EN 15085-5:2007 (E) 4 Introduction Welding is a special process in the manufacture of railway vehicles and their parts. The required provisions for
15、this process are laid down in the standards series EN ISO 3834. The basis of these provisions are the basic technical welding standards in respect of the special requirements for the construction of railway vehicles. This European Standard is aimed at defining the terms of enforcement applicable to
16、European Standards, it is not construed as a substitute to these standards. This European Standard can also be used by internal and external parties, including certification bodies, to assess the organisations ability to meet customer, regulatory and the organisations own requirements.

25、General The relationship between essential welding related tasks and the manufacturing phases to be performed by the responsible welding coordinator or his deputies are given in Table A.1. 4.2 Inspection and testing before welding Additional to Table A.1 the responsible welding coordinator is respon
26、sible for the following tasks: planning of back gouging and sealing run; provision of additional welding-related information for incorporation in the drawings. As evidence that the checks listed in Table A.1 and above have been carried out, the outcome shall be recorded. In order to carry out the ab
27、ove-mentioned tasks, the coordinator may seek support of other company departments. Details of responsibilities for the tasks have to be defined as applied to the organization of the welding manufacturer. The task of the welder or welding operator, before beginning any type of welding activity, is t
28、o check the following items: that the welding machine is validated and efficient; availability of the work instructions; conditions of the edges and the correct tacking of the items to be welded (conditions of cleanliness and assembly of the pieces in accordance with the design and/or the WPS); iden
29、tification of the items to be welded; compliance of the welding consumables with the WPS. 4.3 Inspection and testing during welding The welders or welding operators performing the job have to check and ensure the following: adequate cleaning and shape of the joints during the intermediate passes; co
30、mpliance with the prescribed values of the pre-heating and/or interpass temperatures; compliance with the WPS and/or work instructions; compliance with the sequence of operations if prescribed in specific operating instructions (e.g. the welding sequence plan). EN 15085-5:2007 (E) 7 The process step
31、s and phases in which it is necessary for the welding activity to be supervised by the responsible welding coordinator or his deputy shall be explained by welding planning documents (see EN 15085-4:2007, 4.1). If the welding sequence plan or test plan requires the check of a weld during production,
32、welding shall be continued only after the weld has been checked. 4.4 Inspection and testing after welding 4.4.1 Checks by the welder or welding operator After welding, the welder or welding operator shall carry out the following checks: that the weld is complete; that the weld is cleaned; that the p
33、rofile and dimensions of the weld conform to the drawing. 4.4.2 Self-inspection by the welder or welding operator If a self-inspection system is used, the personnel entrusted with the self-inspection shall be suitably trained and instructed with respect to visual examinations and the requirements of
34、 EN 15085-3:2007, Clause 5, by the responsible welding coordinator or his nominee (deputy, or personnel certified to Level 2 according to EN 473). The inspections carried out by the welder or welding operator shall then be clearly defined (acceptance criteria, dimensioning etc.) and recorded in acco
35、rdance with Table 1. Recording documents shall be signed by the welder or welding operator who carries out the inspection and have to be enclosed with the other inspection documents. A copy of the personal signatures with names in clear, printed text will be held for all personnel who sign inspectio
36、n documents. Alternatively, traceability can be achieved by an electronic system. 4.4.3 Conformity control of welds After welding, the NDT (Non-Destructive Testing) is carried out by certified personnel (except VT; see Table 1). Table 1 defines the type and frequency of the testing to be carried out
37、 during series production. This is based on the relationship between the weld performance class of the welded joint assigned by the design engineer and the resulting inspection class (see EN 15085-3). Testing at the beginning of production: shall be according to the inspection class, 100 % testing o
38、f all welds on each initial item of the series if testing is required in Table 1. Testing during series production: the tests described in Table 1 shall be carried out on products manufactured during series production in accordance with the frequencies indicated therein and as per the weld performan
39、ce class indicated on the drawing by the design engineer. In the case of detecting unacceptable defects during the tests indicated in Table 1, the procedure for management of non-conformance shall be applied, with the extension of the testing as indicated in Clause 7.
