17、gs can identify surface discontinuities. Before delivery and where applicable, these discontinuities can be removed by grinding or by any other process, without affecting the workpiece/component functionality (see Clause 5). DIN EN 10360:2015-10 EN 10360:2015 (E) 5 1 Scope This European Standard def

18、ines the forged components surface repair conditions and control to preserve their functionality. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 functionality of forging set of properties and characteristics of a workpiece/component that pro

19、vides it with the capability of complying with the specified requirements 2.2 repair set of operations carried out in order to remove detected surface defects 2.3 prohibited repair area area of a workpiece/component where the repair is not permitted 2.4 surface imperfection discontinuity identified

20、as not affecting the function of the workpiece/component, which may be left without repair 1 2.5 surface defect discontinuity identified as affecting the workpiece/component function which shall be repaired 1 3 Prohibited repair areas The prohibited repair areas shall be specified by the purchaser,

21、at time of enquiry and order. Supplementary prohibited areas, which can be defined as consequence of the manufacturing process, shall be agreed between manufacturer and purchaser at time of enquiry and order. 4 Removal of surface imperfections Surface imperfections shall be removed only by request o

22、f the purchaser. In case of agreement, the removal procedure shall be the same as for surface defects. 5 Removal of surface defects 5.1 Surface defects removal method Surface defects shall be removed by grinding, scraping, polishing, chipping, machining or by any other process that preserves the wor

23、kpiece/component functionality. Surface defects shall be removed by welding or powder metallurgy only with the agreement of the purchaser. DIN EN 10360:2015-10 EN 10360:2015 (E) 6 The equipment used to remove the surface defects shall be suitable for the grade of the material, the location, the surf

24、ace defect form and the workpiece/component geometry. The manufacturer shall develop the method to avoid masking the imperfections and increasing the repairs. If applicable, the processing should be carried out by successive passes perpendicular to surface defect direction. Following agreement betwe

25、en the purchaser and the manufacturer, the repaired area of the workpiece/component can be retested by the original non-destructive testing (NDT) method 5.2 Surface condition of the repaired area In the repaired area, the surface shall not be altered by an excessive temperature rise and by the prese

26、nce of sharp edges, chatter marks or grooves. Pits may remain after repair; their surface should remain in the continuity of the vicinity surface of the workpiece. 5.3 Operations carried out after the surface defects removal Upon agreement between the purchaser and the manufacturer, an operation whi

27、ch ensures the surface properties similar to those preceding repair can be carried out on the repaired area of the workpiece/component (e.g. shot-blasting, etc.) If, at time of enquiry and order, no agreement has been made between manufacturer and purchaser, the operation is left at the discretion o

28、f manufacturer. 5.4 Acceptance rules for the repair process After repair, the surface of the workpiece/forged component shall fulfil the specified tolerances. Surface tolerances shall be agreed at time of enquiry and in accordance with published standards, e.g. for the hot closed die steel forgings

29、with EN 10243-1 or EN 10243-2, unless otherwise specified. If the repaired workpiece/component does not fulfil the specified tolerances, a new agreement may be done between the purchaser and manufacturer. 6 Operator training The manufacturer shall take any necessary measures to train, qualify and fo

30、llow up the operators entitled to perform the repair operation.
