ULTRASONIC INSPECTION (UT) SERVICE

It is a Non-Destructive Testing (NDT) method that uses high-frequency sound waves to detect surface and subsurface discontinuities in the inspection piece. Ultrasonic Testing (UT) uses high frequency sound waves to perform inspection and measurement. Ultrasonic inspection can be used for defect detection/evaluation, dimensional measurements, material characterization and much more. When there is a discontinuity (such as a crack) in the wave path, some of the energy will be reflected from the defect surface. The reflected wave signal is converted into an electrical signal by the transducer and displayed or recorded in various ways. Both surface and subsurface defects can be detected using ultrasonic inspection, a volumetric inspection method.

This method is used to inspect various product forms including castings, forgings and welding. Structural steel, automotive, petrochemical, power generation and aerospace industries are a few examples that use ultrasonic inspection.
