Each bend test shall be continued until fracture occurs or be terminated when the force limit of the press is reached, provided that the bend test values have reached the values given in Table A.1. For the latter case, the weld shall be notched to ensure that fracture occurs in the welding zone, and the test weld shall be fractured. If fracture occurs about the weld line the fracture surfaces shall be inspected. The details of any weld imperfection shall be recorded in accordance with Annex B. Lack of bond shall not be permitted. Flat spots shall not be considered to be lack of bond. If fracture occurs remote from the weld the fracture surfaces shall be checked for the presence of die burn, which if detected shall cause the process to fail approval. If fracture occurs within the rail for reasons other than die burn then another test weld specimen shall be substituted for testing. The five tested welds shall meet the test requirements for the given rail profile and grade specified in Table A.1 5.3.6 Macro examination Four welds in the finished condition shall be sectioned for macro examination in accordance with D.1 and shall conform to the following requirements: a) The visible heat affected zone shall be of a nominally symmetrical shape about the weld line and fall within the widths of 45 mm maximum and 20 mm minimum. The permissible deviation between the maximum and minimum dimension of the visible heat affected zone on any weld shall not exceed 20 mm. This requirement shall apply equally to the vertical axis cuts through the full rail depth and those taken from each rail foot. b) There shall be no evidence of lack of bond, inclusions, cracks or shrinkage. Imperfections that cannot be positively identified by macro examination shall be inspected by micro examination. c) In case that flat spots are found, they shall be checked by micro-examination at 100 x magnification. If any cracks are found, the process is rejected. 5.3.7 Micro examination Following the completion of the macro examination, a micro examination shall be carried out in accordance with D.2. There shall be no evidence of martensite or bainite at 100 x magnification in the visible heat affected zone. 5.3.8 Hardness testing Two of the four full rail depth longitudinal vertical sections taken for macro and micro examination shall be subjected to hardness testing which shall be carried out in accordance with Annex E. The minimum and maximum hardness values obtained shall conform to the following requirements: a) minimum hardness shall not be less than P - 30 HV30 b) maximum hardness shall not exceed P + 60 HV30 where: P is the average hardness of the unaffected parent rail as measured in the hardness traverse An isolated hardness value falling outside of the stated minima and maxima above shall be permitted when such a hardness value falls between the two adjacent values that conform to the requirements. If these requirements are not met, the process is rejected. SIST EN 14587-2:2009
Figure 3 — Measurement of the rail end squareness 8.3 Rail alignment For reasons of asymmetry all rails shall be welded with the brand marks at the same side. If this cannot be achieved, the contractor shall inform the purchaser accordingly. 8.4 Weld parameter monitoring The welding programme and parameters shall be as those for which approval was granted. Automatic monitoring and recording of the weld parameters shall be required for all production welds. Alterations of preheating parameters due to various rail temperatures are not considered as alterations to the welding program. A bending test according to 8.10.3 shall be carried out in this case. 8.5 Weld identification The weld shall be marked at the time of production by such a means that it can be identified in track as specified by the purchaser in 8.1 f). The means of weld identification shall permit traceability to the records and information obtained at the time of production. 8.6 Visual inspection All of the welds and rails shall be inspected visually for welding, trimming, clamping or profile finishing imperfections, such as tears, cavities, cracks, damage, geometrical non-conformities and thermal damage, in particular, in the electrode contact areas. 8.7 Steps across the weld A weld with a step exceeding the maximum dimension as specified in 4.9 shall be removed from the welded string. The weld shall be removed by cutting at a minimum distance of 100 mm on each side of the weld. Where the step exceeds the limits owing to differences in the rail dimensions, the contractor shall inform the purchaser accordingly. SIST EN 14587-2:2009
