Advantages and Applications of Eddy Current Thermography Testing for Comprehensive and Reliable Defect Assessment
نویسندگان
چکیده
Eddy current thermography testing is an emerging technology in nondestructive testing. This technology combines eddy current and thermographic NDT techniques to provide a fast and efficient method for defect detection and characterisation over a relatively large area. The technique uses induced eddy currents to heat the sample being tested and defect detection is based on the changes of the induced eddy currents flows revealed by thermal visualisation captured by an infrared camera. This work discusses the advantages provided by the eddy current thermography technique and presents results from 3D FEM simulation and experimental investigations of eddy current thermography on defects in metallic samples. The work demonstrates the effectiveness of eddy current thermography in providing comprehensive and reliable defect assessment.
