Abstract

Ultrasonic testing (UT) is a well established Nondestructive Technique. It is based on ultrasonic waves in a frequency range usually from 0.5 to 20 MHz. UT provides a quality control, determination of material properties and a flaw detection with location in all three dimensions. Using echo-technique only a one-sided access of the test component is necessary. A flaw detector provides instantaneous results. Automated systems deliver images like Cscans (top view) and B-scans (view in cross section direction) of hidden defects. In this chapter the physical principles of UT are explained and the parts of an imaging system are described.
