34、015-2:2011 BSI 19971 ScopeThis standard specifies micro hardness tests on transverse sections of welded joints of metallic materials with high hardness gradients. It covers Vickers hardness tests in accordance with ISO DIS 6507-1, normally with test loads of 0,98 N to less than49 N (HV 0,1 to less t
35、han HV 5).Testing should be carried out to ensure that the highest and/or the lowest level of hardness of both parent metal (in the case of dissimilar parent metals) and weld metal are determined.The type and extent of testing shall be as specified by an application standard or by agreement between
36、the contracting parties.This standard does not cover the hardness test as described in EN 1043-1.2 Normative referencesThis European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text an

For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

39、tests may be carried out in the form of rows of indentations (R), or as individual indentations (E).When types of weld are not shown in the examples, the test procedure shall be appropriate to the welded joint.Unless otherwise specified, the test shall be carried out at ambient temperature (235) C.4

42、n accordance with ISO/DIS 6507-1.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 surface shall be carried out carefully so that the hardness of the surface to be tested is not affected met
43、allurgically.The surface to be tested shall be properly prepared and preferably etched, so that accurate measurements of the diagonal of the indentations can be achieved in the different zones of the welded joint.6 Test procedure6.1 Rows of indentations (R)Figures 1 to 3 give examples of hardness in
44、dentations made in rows, including the distance from the surface, so that these rows, or parts of them, permit assessment of the welded joint. If required by the contracting parties, additional rows of indentations and/or different locations may be made. The location shall be stated in the test repo
45、rt.In metals such as aluminium, copper and their alloys, the rows on the root-side of butt welds (see figure 1) are not necessary.The number and spacing of indentations shall be sufficient to define hardened or softened regions due to welding. Recommended distances between the centrepoint of the ind

Example of rows of indentation (R) in butt welds in ferrous metals(Dimensions in millimetres)Sufficient indentations shall be made to ensure that unaffected parent metal is tested. In the weld metal, the distance between indentations shall
48、 be selected and checked so that the results obtained enable assessment of the welded joint to be made.For metals that harden in the HAZ as a result of welding, two additional indentations in the HAZ shall be made at a distance not exceeding 0,5 mm between the centrepoint of the indentation and the fusion line (see figure 2).For other joint configurations or metals (e.g. austenitic steels) special requirements may be given by an application standard or by agreement between the contracting parties.Table 2.
