Macro-range test forces
Test forces in the macro range are forces above 30 kilopond, used to determine the overall properties of large-volume components. They minimize the influence of local microstructural inhomogeneities.
Physical-Chemical Mechanism of Action
Macro-scale test forces are mechanical forces applied to a material to test its mechanical properties. These forces are typically over 30 kiloponds and serve to determine the overall properties of a component without accounting for the influence of local microstructural inhomogeneities.
Metallurgical Relevance & Welding Risks
Using macro-scale test forces is important to ensure that components meet their desired mechanical properties. Incorrect application or too-low forces can cause local microstructural inhomogeneities to skew the test result. This can lead to misunderstandings in quality assurance and create potential safety risks.
Workshop Practice & Action Instructions
When performing hardness tests with macro-scale test forces, follow these steps:
• Use forces above 30 kiloponds.
• Make sure the specimen is large enough to minimize the influence of local microstructural inhomogeneities.
• Keep test conditions constant and document all relevant parameters.
