Test load
Test force is the defined mechanical force with which an indenter is pressed into the material or a tensile specimen is loaded. It affects the size of the indentation or the applied stress and is crucial for the strength and hardness of the material.
Physical-Chemical Mechanism of Action
The test force is the force applied to a material to test its mechanical properties. In a hardness test, an indenter presses into the material and measures the size of the indentation or the stress. In a tensile test, you pull on the material and measure the force until it breaks.
Metallurgical Relevance & Welding Risks
The test force gives you information about the strength and hardness of the material. A value too low can mean the material is too soft and not strong enough. A value too high can show the material is too hard and may be prone to cracking or breaking.
Workshop Practice & Action Instructions
The test force should be measured accurately and adjusted depending on the material and application. For hardness tests, the force is measured in Newtons (N) or kilograms (kg), for tensile tests in Newtons (N). It's important to carry out the measurement correctly to get reliable results.
