In industrial applications, ultrasonic testing is widely used on metals, plastics, composites, and ceramics. The only common engineering materials that are not suitable for ultrasonic testing with conventional equipment are wood and paper products.

What is ultrasonic testing used on?

Ultrasonic testing (UT) is a non-destructive test method that utilizes sound waves to detect cracks and defects in parts and materials. It can also be used to determine a material's thickness, such as measuring the wall thickness of a pipe.

What is the working 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.
