15、 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 standards series EN ISO 3834. The basis of these provisions are the basic technical welding standards in respect of the special requireme
16、nts for the construction of railway vehicles. This standard is aimed at defining the terms of enforcement applicable to European Standards, it should not be construed as a substitute to these standards. This standard can also be used by internal and external parties, including certification bodies,
17、to assess the organisations ability to meet customer, regulatory and the organisations own requirements. EN 15085-2:2007 (E) 5 1 Scope This series of standards applies to welding of metallic materials in the manufacture and maintenance of railway vehicles and their parts. This part of the series def
18、ines the certification levels as well as the requirements for welding manufacturers and describes the procedure for the recognition of welding manufacturers. 2 Normative references The following referenced documents are indispensable for the application of this document.

28、nd sub-assemblies, are specified by the standard series EN ISO 3834. Dependant on the certification level, the requirements of EN ISO 3834-2, EN ISO 3834-3 or EN ISO 3834-4 shall be fulfilled in principle (see Annex A). Welding manufacturers, which carry out welding work on railway vehicles, compone
29、nts and sub-assemblies, shall be certified according to this standard, if specified. Compliance with the requirements shall be checked and certified by a recognised manufacturer certification body (see Clause 6). Four certification levels (CL) are laid down for the certification of welding manufactu
30、rers (Level 1 to Level 4). Level 1 to Level 3 depends on the weld performance classes CP A to CP D of the welded joints specified in EN 15085-3:2007, Table 2. Table 1 contains a description of the certification level and the allocation in the weld performance classes. The required certification leve
31、l depends on the following two items: 1) Table 1; 2) safety relevance of the components or sub-assemblies where the welded part is integral (see list beneath Table 1). 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,
32、 EN ISO 15614-12 and EN ISO 15614-13 are relevant. EN 15085-2:2007 (E) 7 Table 1 Certification level Description Certification leve (CL) This level applies to welding manufacturers which manufacture welded railway vehicles or their welded parts with welded joints classified in weld performance class
33、es CP A to CP D. Certification level CL 2 to CL 4 is included. CL 1 This level applies to welding manufacturers which manufacture welded parts of railway vehicles with welded joints classified in weld performance classes CP C2 to CP D. Welded joints classified in weld performance class CP C1 are inc
34、luded if these welds are checked according to weld inspection class CT 1 according to EN 15085-5:2007, Table 1. Certification level CL 4 is only included according to welded joints of certification level CL 2 or CL 3. CL 2 This level applies to welding manufacturers which manufacture welded parts of
35、 railway vehicles with welded joints classified in weld performance class CP D. CL 3 This level applies to manufacturers which do not weld but design railway vehicles and parts of rail vehicles or buy and assemble or sell them. Certification not required for welding works of certification level CL 3
36、. CL 4 Because of their safety relevance the following components and sub-assemblies shall be welded by welding manufacturers with a certification level CL 1. bogie frames and bolsters; body shell components (e.g. under frames, structures); buffers and draw gear; wheel set components (e.g. wheel set
37、 mountings, axle boxes, spring supports); brake equipment (e.g. magnetic track brake, brake rods, brake triangles, brake cylinders, brake cross beams); supporting frames for heavy components (e.g. traction units, pantographs); welded components for drag transmission from bogie to vehicle; vibration
38、dampers and their link between bogie and vehicle or between vehicles; finishing welding of castings within components indicated above; external fuel tanks. Annex A contains information about possible classifications of the certification levels for further components and sub-assemblies of railway veh
39、icles. EN 15085-2:2007 (E) 8 According to EN 15085-3:2007, certification level CL 1 to CL 3 necessary for the product shall be clearly indicated in the engineering documentation (e.g. on the drawings). If required by the customer, the certification level shall be agreed with him respecting the natio
40、nal safety authority. 5 Quality requirements for the welding manufacturer 5.1 Staff requirements 5.1.1 Welders and welding operators The welding manufacturer shall have welders and welding operators with qualification in accordance with EN 287-1, or EN ISO 9606-2 or with EN 1418. Qualification shall
41、 cover each the welding processes, material groups, joint types and welding positions needed for production. Such qualification should be carried out by either: accredited examining body, responsible welding coordinator of the manufacturer, recognised by the manufacturer certification body as specified in 5.1.2. If fillet welds are done in production a fillet weld test piece is necessary. 5.1.2 Welding coordination The welding manufacturer shall have suitably experienced welding coordinators with the relevant technical knowledge according to EN ISO 14731. The manufacturer shall clearly pr
