What is ISO 9015-2 - Microhardness testing of welded joints in metallic materials about?
ISO 9015-2 is an international standard covering microhardness testing of welded joints in metallic materials, enabling the measurement of hardness distribution in the weld to ensure strength, uniformity and quality of the welding.
ISO 9015-2 specifies microhardness testing on transverse sections of welded joints of metallic materials with high hardness gradients.
ISO 9015-2 covers Vickers hardness tests in accordance with ISO 6507-1, normally with test loads of 0.98 N to less than 49 N (HV 0.1 to less than HV 5).
NOTE Testing ensures that the highest and/or the lowest level of hardness of both parent materials (in the case of dissimilar materials both parent materials) and weld metal is determined.
Who is ISO 9015-2 - Microhardness testing of welded joints in metallic materials for?
ISO 9015-2 on Microhardness testing of welded joints in metallic materials is useful for:
- Microhardness testing laboratory
- Quality assurance services
- Welding industries
- Metallic industrial plant
Why should you use ISO 9015-2 - Microhardness testing of welded joints in metallic materials?
Testing of microhardness is done on welded joints to determine the material’s hardness and their resistance to deformation at a microscopic level. It is used to check for decarburization, carburization, and the state of the weld and heat-affected zones in welded parts, as well as to evaluate the quality of welded metal components.
ISO 9015-2 provides users with a test method to determine the microhardness of welded joints. ISO 9015-2 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly.
ISO 9015-2 assists users to implement microhardness testing on transverse sections of welded joints of metallic materials with high hardness gradients, ensuring the quality of welded joints.
With the adoption of ISO 9015-2, users can implement microhardness testing of welded joints to ensure the hardness and resistance to deformation in metallic materials.
