BS EN ISO 15614-13:2021 pdf free download – Specification and qualification of welding procedures for metallic materials一Welding procedure test.
A macrosection transverse to the weld shall be prepared and etched in order to clearly show the weld zone, the heat-affected zones (IIAZ) and the unaffected parent material.
5.2.6 Bend test specimen using thin sheets
The test specimen shall be prepared in accordance with ISO 15620:2019. Figure 8.
Any deviations from the requirements shall be defined in the design specification.
63 Destructive tests
6.3.1 Tensile test
Tensile testing shall he carried out in accordance with ISO 6892-1.
6.3.2 Three-point bend test
Bend testing shall be carried out in accordance with iSO 5173.
6.3.3 Cupping test
The cupping test can be carried out using Erichsen testing equipment.
6.3.4 Bend test
Bend testing shall be carried out in accordance with ISQ 15’2Q.
6.4 Macrosection
The test specimen shall be prepared as a cross-section cut through the weld, which shall then be etched to show the weld, the HAZ and the unaffected parent material. The test shall he carried out in accordance with iSO 17639.
6.5 Hardness distribution
The surface of the cross-section to be tested shall be properly prepared and preferably etched, so that accurate measurements of the diagonal of the indentations can be obtained in the different zones of the welded joint. The hardness can be determined in one or more traces. A trace consists of a row of hardness indentations, where all individual indentations are in a straight line. In the case of a circular cross-section, if only one trace has been defined in the design specification, the trace shall be arranged as a parallel at 0,6 times the radius to the centre axis. With a steel sheet section, the trace shall be of 0,6 times the sheet thickness and positioned parallel to the sheet surface. The hardness measurement shall be carried out in accordance with ISO14271.
6.6 Re-testing
If the component or test piece fails to comply with any of the requirements for the visual examination or NDT specified, one further component or test piece shall be welded and subjected to the same tests. If the test results of this additional component or test piece also do not comply with the requirements, the welding procedure test is considered to have been failed.
If any test specimen fails to comply with the requirements for destructive testing, due only to weld imperfections, two further test specimens shall be obtained for each one that failed. Each additional test specimen shall be subjected to the same tests as the initial, failed, test specimen, If either of the additional test specimens fails to comply with the requirements, the welding procedure test is considered to have been failed.
