The ISO 9015 series is an International Standard that discusses destructive tests on welds in metallic materials. ISO 9015 provides the requirements of hardness testing for welded joints.
ISO 9015-1 is the first part of the ISO 9015 series, and specifies hardness tests on transverse sections of arc welded joints of metallic materials. ISO 9015-1 covers Vickers hardness tests in accordance with ISO 6507-1, normally with test loads of 49,03 N or 98,07 N (HV 5 or HV 10).
The principles may be applied to Brinell hardness testing (with appropriate testing loads of HB 2,5/15,625 or HB 1/2,5) in accordance with ISO 6506-1 and micro hardness testing in accordance with ISO 6507-1 and ISO 9015-2.
Testing should be carried out to ensure that the highest and the lowest level of hardness of both parent metal and weld metal is determined.
Note: ISO 9015-1 does not apply to test welds in austenitic stainless steel.
ISO 9015-1 on arc welded joints hardness testing is useful for:
ISO 9015-1 is also useful for entities such as:
Hardness testing for joints plays an important role in verifying if the material and the welded joint has the properties necessary for its intended use.
ISO 9015-1 walks you through the test with details such as symbols and terms, preparation of test specimens, as well as the test procedure.
Guidance in ISO 9015-1 assist you in hardness tests on transverse sections of arc welded joints of metallic materials, ensuring the quality of welded joints.
With the adoption of ISO 9015-1, you can implement a hardness test on arc welded joints to ensure the hardness and resistance to deformation in metallic materials.
