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

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,
