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.
