NOTE In Annex C EURONORM 19, 53 and 54 are mentioned with corresponding nation

Therefore they are not mentioned in this clause. 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 10079:1992, EN 10163-2:2004 and EN 10163-3:2004 apply. NOTE For

25、the most common surface discontinuities see the descriptions in Annex A. In Annex B the terms can be found in their respective languages. 4 General Responsibility for the required surface condition, whether the product is delivered descaled or not, rests with the material producer, who has to take t

26、he necessary precautions. The producer can only take account of EN ISO 15609-1, Specification and qualification of welding procedures for metallic materialsprocedure specification Part 1: Arc welding (ISO 15609-1:2004). Welding EN ISO 15614-1, Specification and qualification of welding procedures fo

28、e subsequent descaling or working operations by the user, the material is found to be defective because of faulty rolling or processing by the producer, the producer shall be given opportunity to repair the product provided that this is not in conflict with the appropriate material or product standa

29、rd. 5 Classification The surface requirements and repair conditions are subdivided into classes as specified in EN 10163-2 and EN 10163-3. 6 Requirements 6.1 Depth and affected area of discontinuities 6.1.1 Depth To differentiate the surface discontinuities in terms of imperfections and defects, the

30、 depth of representative surface discontinuities shall when necessary be measured. The measurement shall be carried out from the surface of the product. The depth of the discontinuities chosen as representative ones shall be determined after the discontinuity has been removed by grinding. 6.1.2 Affe

31、cted area Areas affected by surface discontinuities shall when necessary be determined as follows: a) for isolated discontinuities (Figure 1) the affected area is obtained by drawing a continuous line which follows the circumference of the discontinuity at a distance of 20 mm or by drawing a rectang

32、le whose sides are 20 mm from the edges of the discontinuity; b) for discontinuities appearing in a cluster (Figure 2), the affected area is obtained by drawing a continuous line which follows the circumference of the cluster at a distance of 20 mm or by drawing a rectangle whose sides are 20 mm fro

33、m the continuous line which follows the cluster or by the product edge if this is closer. For discontinuities appearing in a line (Figure 3), the affected area is obtained by drawing a rectangle the sides of which are 20 mm in the longitudinal direction and 20 mm in the transverse direction from the

34、 edge of the discontinuity or by the product edge if this is closer. Multiple appearing discontinuities whose edges are closer together than 40 mm shall be considered as one cluster.

36、 6.2 Repair requirements The repair requirements for each class (see Clause 5) are specified in EN 10163-2 and EN 10163-3. 6.3 Repair procedures 6.3.1 Grinding If a discontinuity has to be repaired, it shall be removed completely by grinding to its full depth. The ground areas shall have a smooth tr

37、ansition to the surrounding surface of the product. In case of dispute complete elimination of the defect may be demonstrated by magnetic particle or by dye penetrant test techniques. 6.3.2 Welding Defects shall be completely eliminated before any weld repair is commenced. This procedure shall not r

38、educe the thickness of the product to less than 70 % of its nominal thickness. Prior to weld repair of edges of flat products, the depth of the groove, measured from the edge inward, shall not exceed the nominal thickness of the product with a maximum of 30 mm. The welding shall be carried out by op

39、erators qualified in accordance with EN 287-1. Welding procedures shall be carried out in accordance with EN ISO 15607, EN ISO 15609-1 and EN ISO 15614-1. The weld shall be free of any lack of fusion, undercutting, cracks and other defects which could impair the workability or use of the product in

40、question as specified by the purchaser. The deposited weld material shall reach above the plate surface and shall subsequently be ground smooth and level with the product surface. After grinding smooth, ordered product thickness tolerances apply to the ground area. After repair a post-weld heat trea

41、tment may be agreed between the producer and the purchaser. Proper repair shall be verified by ultrasonic, radiographic, magnetic particle or dye penetrant inspection. When the method has not been specified by the purchaser, the choice of the method is at the manufacturers discretion. If requested a

42、t the time of the order for every welding repair the producer shall provide reports containing a sketch, showing dimensions and location of the defect and full details of the repair procedure, including the welding consumables, eventual post-weld heat treatment and non-destructive testing. NOTE In c

43、ertain applications, such as otherwise unwelded components of structures for which the choice of steel grade with respect to notch ductility would be determined by the presence or absence of welding or in which permissible stresses are limited by considerations of fatigue, repair by welding may not

44、be satisfactory or may require special inspection after completion. In EN 10163-2 and EN 10163-3 classes and subclasses are defined for which repair by welding is not allowed. EN 10163-1:2004 (E) 9 Annex A (informative) Description of most common discontinuities A.1 General For the most common surfa

45、ce discontinuities the following descriptions apply:1) A.1.1 rolled-in scale and pitting marks on the rolled surface varying in shape, thickness and frequency Rolled-in scale results from the inherent surface scaling of the stock before or during hot-rolling or processing. A.1.2 indentations and rol

46、l marks indentations (depressions) or hot-roll marks (protuberances) are normally attributed to the natural wear of rolls or pinch rolls These discontinuities can be distributed at definite distances apart or irregularly throughout the length and width of the stock. A.1.3 scratches, grooves mechanic

47、al scoring at the surface Scratches are mostly parallel or at right angles to the rolling direction. They may be slightly rolled over and seldom contain scale. This scoring is caused by friction between the stock and parts of the equipment due to relative movements. A.1.4 spills, slivers minute surf

48、ace discontinuities of an irregular and shell like nature Spills and slivers are elongated in the direction of rolling, their extent depending on the degree of reduction. They are still connected, as minute particles of shell, to the base metal at certain points. A.1.5 blisters blow hole located clo

49、sely beneath the surface Blisters often appear during hot-rolling. A.1.6 sand patches non-metallic internal inclusions, elongated in the direction of rolling and distinctly coloured A.1.7 cracks narrow line of fracture on the surface 1) Photographs of the most common surface discontinuities can be found in the VDEh brochure “Oberflchenfehler von warmgewalzten Flachstahlerzeugnissen“ (edition 1978) published by Verlag Stahleisen GmbH, Postfach 105145, 40042 Dsseldorf, Germany.
