Indentation depth measuring system
A measuring system for continuous recording of the vertical displacement of the indenter during loading and unloading. It determines instrumented hardness values and elastic material fractions.
Physicochemical mechanism of action
The indentation depth measuring system measures the vertical displacement of the indenter using a sensor. This sensor records the movement during the entire loading and unloading cycle, leading to determination of the indentation depth.
Metallurgical relevance & risks in welding
Accurate measurement of indentation depth is crucial for weld quality. Too shallow indentation depth can lead to incomplete fusion and missing mechanical properties, while too deep a depth poses risks of overpressure and distortion.
Shop practice & instructions
Use the measuring system for continuous monitoring of indentation depth. Ensure that the sensor is correctly positioned and that displacement is measured in seconds or millimeters. If values are inconsistent, check welding parameters like voltage and travel speed.
