How to Operate Thicknesses Test Machine (DMS Go+)Part-1

This is NDT video for thickness testing Equipment. What is the basic principle of ultrasonic testing? Driven by the pulser, the transducer generates high frequency ultrasonic energy. The sound energy is introduced and propgates through the materials in the form of waves. When there is a discontinuity (such as a crack) in the wave path, part of the energy will be reflected. back from the flaw surface. What is the advantage of ultrasonic testing process? Advantages of ultrasonic inspection as a method of Non-Destructive Examination are: Internal defects can be detected and sized when a validated procedure is applied. Thick specimens take no more time to examine than thin ones, assuming correct instrumentation set up. Access to only one side of the component is needed.
