Ultrasonic Testing is the process of transmitting high-frequency sound waves into a material in order to detect changes in the material’s properties.

Ultrasonic Testing uses sound waves to detect defects or flaws inside material.

These sound waves travel through the material with some energy loss (attenuation) and are reflected and refracted at interfaces. The echoes are then analysed to define and locate discontinuities.

It is used in many industries including steel, Stainless Steel and aluminium, aerospace, automobiles and others.

• Phased Array Ultrasonic Testing :
  Phased Array Ultrasonic Testing (PAUT) is a UT technique that develops a set of UT probes made up of numbers of small essentials. Each of the essentials in a PAUT machine is able to pulse individually. This allows the system to direct focused beam through various angles and distances.


• Time of Flight Diffraction :
  Time of Flight Diffraction (TOFD) is a UT Technique uses the time of flight of an ultrasonic pulse to find the location of a reflector. A pair of ultrasonic transducers is being used to find the Time of Flight. The transmitter emits low frequency waves that propagate at an angle. They only divert back to the receiver if they hit a defect.
