The Ultrasonic Testing (UT) Level I course includes a basic introduction to the theory and principles of ultrasound including frequency, velocity, and wavelength. It addresses the variables related to the propagation, reflection, and attenuation of sound as well as the responses from discontinuities. The student will learn to understand the display and be able to calibrate the UT instrument and identify the location of reflectors in various test specimens. UT equipment and transducers are demonstrated. UT is also used for precise thickness measurements and the basic procedure for this is also covered. A number of techniques and applications will also be presented including discussions on the data required for precise reporting. This course is essential for those desiring to enter and specialize in UT. It is also beneficial for those who will not be practitioners but who want to have a general understanding of the basic principles of Ultrasonic Testing. 

Ultrasonic Testing (UT) Level II is an extension of UT Level I and delves into the theory and principles to a much greater depth. After a review of the basic UT Level I subjects, variables such as beam profile, dead, near and far zones, acoustic impedance, absorption and scattering are presented. Other subjects essential for performing angle beam inspection of welds include mode conversion, refraction, and attenuation are covered. Calibration of the UT instruments is demonstrated as well as the examination of several test specimens. Immersion and through transmission are discusses along with a variety of other techniques. The evaluation and interpretation of test results along with the need for complete and accurate test reporting are presented. This is an essential course for those practitioners who will be pursuing a career in Ultrasonic Testing and for those striving for certification as a Level II.
