Ultrasonic testing (UT) is a technique which administers high frequency sound waves, within the range of 500 kHz to 20 MHz travelling through a material body to inspect characteristics including:

• Defect evaluations
• Material inconsistencies
• Inclusion and crack formation studies
• Dimensional measurement
• Material characterisation

The ultrasonic apparatus consists of a pulser/receiver along with a transducer and a display device. As the ultrasonic waves travel through the material medium, times taken for the pulse to reflect from inclusions, material boundaries, cracks etc. are translated into a measurement through the conversion to an electrical signal.
