In Ultrasonic testing we can find the flaws through using sound waves, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz are launched into materials to detect internal flaws or to characterize materials. …Productivity and quality are the buzz words in quality control and in-service inspection and ultrasonic Non-Destructive testing (NDT) is certainly the answer. Ultrasonic technology is used to measure wall thickness, detect hidden cracks and other anomalies affecting structural integrity.

Ultrasonic Testing for the non-destructive testing of construction components and material has increased the importance of the method for industrial quality control.
