In ultrasonic testing, high-frequency sound waves are transmitted into a material to detect imperfections in material properties. The range has been found to be between 10 Hz to 20 Hz frequency Sound waves above 20 KHz are commonly referred to as Ultrasonic. The most commonly used ultrasonic technique is pulse echo, whereby sound is introduced into a test object and reflection(echos) from internal imperfections or the part’s geometrical surfaces are returned to a receiver. The Ultrasound waves are generated by piezoelectric transducers, which convert
