Mobile Eddy Current Crack Measurement The principle of eddy current method is to induce an energy flux into the material to be tested with an EC-probe by generating a magnetic field that penetrates the material causing eddy currents. Any defects or irregularities in the grain structure disturb the energy flow leading to indications.
This is best suited to:
- Testing for surface cracks on turbine blades, on wheels, on wings around rivets etc. at aircrafts
- Testing of surface cracks on bridges
- Testing of surface cracks on gas pipelines
- Detection and evaluation of surface cracks on semi-finished products
- Simple sorting tasks, identification of hardness changes and detection of surface cracks on automotive components
- The flaw resolution is approximately 20 µm
