Summary
The course deals with the main directions of NDT in the energy industry. Students will be acquainted with NDT methods for defect detection on the surface or under the surface as well as NDT methods for detection of in-volume defects, including advanced ultrasonic methods, i. e. (TOFD – Time of Flight Diffraction), Phased Array, Creep Wave, Guided Wave. In addition, attention is paid to methods of monitoring the defect growth (acoustic emission, potential method) and to NDT methods for monitoring the structure state, including assessment of structural changes due to creep.
