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, including mode conversion, refraction, and attenuation are Calibration of the UT instruments is demonstrated, as well as the examination of several test specimens. Immersion and through transmission are discussed 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 essential course for those practitioners who will be pursuing a career in Ultrasonic Testing and for those striving for certification a Level II.
