DIN EN ISO 9015-1:2011-05 EN ISO 9015-1:2011 (E) 3 1 ScopeThis part of ISO 9015 specifies hardness tests on transverse sec

22、tions of arc welded joints of metallic materials. Itcovers Vickers hardness tests in accordance with ISO 6507-1, normally with test loads of 49,03 N or 98,07 N (HV 5or HV 10).However, the principles may be applied to Brinell hardness testing (with appropriate testing loads of HB 2,5/15,625or HB 1/2,

23、5) in accordance with ISO 6506-1 and micro hardness testing in accordance with ISO 6507-1 andISO 9015-2.NOTE Testing should be carried out to ensure that the highest and the lowest level of hardness of both parent metal andweld metal is determined.This part of ISO 9015 does not apply to test welds i

31、 in ISO 6506-1.5 Preparation of test specimensThe preparation of the test specimen shall be in accordance with ISO 6507-1 or ISO 6506-1.A cross-section of test piece shall be taken by mechanical cutting, usually transverse to the welded joint.This operation and the subsequent preparation of the surf

32、ace shall be carried out carefully so that the hardness ofthe surface to be tested is not affected metallurgically.The surface to be tested shall be properly prepared and preferably etched, so that accurate measurements of theindentations can be obtained in the different zones of the welded joint.6

33、Test procedure6.1 Rows of indentations (R)Figures 1 to 7 give examples of hardness indentations made in rows including the distance from the surface in sucha way that these rows or parts of them permit an assessment of the welded joint. If required by the contractingparties, additional rows of inden

34、tations and/or different locations may be made. The location shall be stated in thetest report.In metals such as aluminium, copper and their alloys, the rows on the root-side of butt welds see Figure 2 a) maybe unnecessary. Typical rows for T-joints in these materials are given in Figure 2.DIN EN IS

35、O 9015-1:2011-05 EN ISO 9015-1:2011 (E) 5 The number and spacing of indentations shall be sufficient to define hardened or softened regions due to welding.The recommended distance between the centrepoint of the indentations in the heat-affected zone (HAZ) is given inTable 2.NOTE 1 Table 2 also appli

36、es with Brinell testing using the same distances provided appropriate loads are used.Sufficient indentations shall be made to ensure that unaffected parent metal is tested. In the weld metal, thedistance between indentations shall be selected and checked so that the results obtained will enable asse

37、ssmentof the welded joint to be made.For metals which harden in the HAZ as a result of welding, two additional indentations in the HAZ shall be made ata distance u 0,5 mm between the centrepoint of the indentation and the fusion line (see Figures 3 to 7).For other joint configurations or metals (e.g

38、. austenitic steels) special requirements can be given by the relevantapplication standard or by agreement between the contracting parties.NOTE 2 For electroslag welds, the loads given in Table 2 may be used. Rows of indentations for electroslag welds can bemade similar to Figure 1 a).Table 2 Recomm

The series 1 to 4 gives

41、information about theunaffected parent metal, the series 5-10 refers to the HAZ and the series 11 to 14 to the weld metal. Otherwise, thelocation of the indentation can be determined on the basis of metallographic examination.To prevent the influence of deformation caused by an indentation, the mini

42、mum distance between the centrepointof individual indentations in any direction shall be not less than 2,5 times the mean diagonal/diameter of thenearest adjacent indentation.For metals which harden in the HAZ as a result of welding, at least one indentation shall be made in the HAZ at adistance u 0

43、,5 mm between the centrepoint of the indentation and the fusion line.For testing with individual indentations, the areas shall be numbered as shown in Figure 8.DIN EN ISO 9015-1:2011-05 EN ISO 9015-1:2011 (E) 6 7 Test resultsThe hardness values shall be recorded in relation to the position of the in
