Ultrasonic Testing is used for the detection of internal and surface defects in sound conducting materials. Ultrasonic Thickness Testing permits quick and reliable measurement of thickness without requiring access to both sides of an object, tank or piping. A pulse-echo ultrasonic thickness gauge determines the thickness of a sample or structure by measuring the time required for a short ultrasonic pulse, generated by a transducer, to travel through the thickness of the material being tested, reflect off the back surface, and return to the transducer. The transit time is then measured and divided by two to account for the signal to and back, and then multiplied by the velocity of sound in the test material.
Ultrasonic testing can be conducted manually (technician) or through the use of a Magnetic Crawler
