EN 15085-4:2007 (E) 4 Introduction Welding is a special process in the manufacture of railway vehicles and their parts. The required provisions for this process are laid down in the s
14、tandards 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 standard is aimed at defining the terms of enforcement applicable to European Standards, it should not be constru
15、ed as a substitute to these standards. This 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.

28、 4.1 Welding planning documents 4.1.1 General Welding planning documents shall be prepared by the manufacturers with the assistance of the recognised welding coordinator Level A for new and converted vehicles and maintenance of rail vehicles (see EN 15085-2). Type, scope and time of the submission a
29、nd inspection should be agreed between customer and manufacturer. Welding planning documents may include working plans, welding sequence plans, test planning documents and welding procedure specifications. 4.1.2 Working plans For the production of railway vehicles it is necessary to have working pla
30、ns for the following sub-assemblies: bogie (sub-assemblies, assembly); 1) For railway applications, only EN ISO 15614-1, EN ISO 15614-2, prEN ISO 15614-3, EN ISO 15614-4, EN ISO 15614-7, EN ISO 15614-11, EN ISO 15614-12 and EN ISO 15614-13 are relevant. EN 15085-4:2007 (E) 7 underframe (with sub-ass
31、emblies); body (side wall, end wall, roof); further sub-assemblies with high safety and functional requirements (e.g. cardan shafts, brake cross members, motor housing, hollow shaft drive, drawbar coupling, bogie pivot pin, cross bearer). 4.1.3 Other welding planning documents For more complicated a
32、ssemblies welding sequence plans are necessary, e.g. for: bogies (bogie bolster, bogie centre plate including bogie pivot pin member, solebar, headstock, bogie pivot pin cross member, traction bar coupling, assembly of solebar and cross member); underframe (including cross member, solebar, headstock
33、, bogie pivot pin cross member, traction bar coupling). Standardised welding sequence plans (that applies for different types of vehicles) are also allowed. Furthermore, other welding planning documents may be necessary (e.g. tacking sequence plans, repairing plans, test plans, documents for jigs an
34、d tools, remarks for protection of labour and health, plans for separating of damaged parts, special instructions for electronic parts). These details shall be determined by the responsible welding coordinator and/or the customer. 4.1.4 Welding procedure specification For welds with welding performa
35、nce classes CP A, CP B, CP C1, CP C2 and CP C3, welding procedure specifications according to EN ISO 15609-1 to EN ISO 15609-5, to EN ISO 14555 or to EN ISO 15620 are necessary. For weld performance class CP D this is only necessary if the customer demands it. Dependent on the weld performance class
36、es according to EN 15085-3, the following evidences are necessary for the welding procedure specification: Weld performance class CP A: Evidence according to any of the following standards: EN ISO 156142)or EN ISO 15620; EN ISO 15613 only if a WPQR according to EN ISO 15614 exists; for materials wit
37、h Reh 500 MPa or fully mechanised welding processes: EN ISO 15614. For the WPQR the acceptance criteria of weld performance class CP A (EN 15085-3:2007, Table 5 and Table 6) shall be fulfilled. Weld performance classes CP B, CP C1, CP C2: Evidence according to any of the following standards: EN ISO
38、15613, EN ISO 14555, EN ISO 15620; if necessary for component or the material: EN ISO 15614. Weld performance class CP C3: Evidence according to any of the following standards: EN ISO 15610, EN ISO 15611, EN ISO 15612, EN ISO 15613, EN ISO 14555, EN ISO 15620; if necessary for component or the mater
39、ial: EN ISO 15614. Weld performance class CP D: According to the requirements of the customer. In general, every WPS shall be covered by a WPQR, except for weld performance class CP D unless specified in the contract. 2) See footnote 1).

40、cording to EN ISO 15614-1 and EN ISO 15614-2, see Introduction of EN ISO 15614-1:2004 and EN ISO 15614-2:2005. 4.2 Production weld tests 4.2.1 General 4.2.1.1 Aim and objective of production weld tests If necessary, production weld tests shall be carried out. The aim and objective of production weld
41、 tests is: to check and ensure that the design is satisfactory as specified in EN 15085-3; to prove the welding conditions; to demonstrate the skill of the welders; to demonstrate the quality of the weld. One production weld test can be used for several tasks indicated above. 4.2.1.2 Realization and
42、 amount of testing of production weld test The production weld test shall be carried out under the same manufacturing conditions as the real product. They shall be carried out under the supervision of the responsible welding coordinator and they shall be documented. Production weld tests should be welded in accordance with EN ISO 15613. They may be welded separately as test plates,
