Training Duration 120 hours (12 days)

Basic Principle – Ultrasonic Testing (UT)

Ultrasonic testing uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more.


This course provides detailed theoretical and practical information on all the commonly encountered Ultrasonic Testing (UT) techniques. Candidates will have the opportunity to use the various techniques on welds, castings and wrought products.
This course meets the training hour requirements as specified by the American Society of Non-Destructive Testing (ASNT) Recommended Practice documents SNT-TC-1A.
