Present the advanced techniques of ultrasonic material testing and ultrasonic wall thickness measurement. Get acquainted with the principles of certain ultrasonic testing techniques with regard to the specifics of the material and geometry of the test component. Develop a critical approach to ultrasound testing in terms of probability of detection and characterization of indications.

Student responsibilities:

Class attendance and active participation of students in the implementation of examinations during exercises. Preparation of assignments related to exercise activities.

Grading and evaluation of student work over the course of instruction and at a final exam:

Two colloquia - evaluation (2 x 35%) Evaluation of assignments (30%)

Upon successful completion of the course, students will be able to (learning outcomes):

1 . Distinguish the principles of ultrasonic testing techniques in relation to the interaction with the material of the tested component.

2 . Explain the influences of relevant factors on the reliability and validity of ultrasound test/measurement results.

3 . Compare the advantages and limitations of individual ultrasonic testing / measurement techniques.

4 . Justify the applicability of individual ultrasonic test techniques with regard to the required test objective and with regard to the characteristics of the tested component / structure (or material) and with regard to the field of application.
