Subject aims expressed by acquired skills and competences

In this course students will be acquainted with the main methods of non-destructive control, which are used in energy industry. Students will be able to choose the appropriate NDT technique for the selected device, conditions of its loading, the operational history, etc. They will be able to evaluate results of the NDT analysis. They will be aware of the limits of the use of individual methods. They will know the directions of further development in the core areas of the NDT.

Teaching methods

Experimental work in labs


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.
