The detection and location of discontinuities are enabled by the interpretation of ultrasonic wave reflections generated by a transducer.

Information from the ultrasonic inspection can be presented in a number of formats:

• A-Scan displays the amount of received ultrasonic energy as a function of time
• B-Scan displays a profile view (cross-sectional) of a specimen
• C-Scan displays a plan type view of the specimen & discontinuities

The relationship of flaw size, flaw distance and flaw reflectivity are complex and considerable skill is required to interpret the display. With over 10 years of experience in this field, we are able to understand and give actual interpretation of inspection exercise.
