Ultrasonic Inspection is a Non Destructive Testing (NDT) method where beams of high frequency sound waves are introduced into materials. By measuring the time of flight of the sound beam, the thickness of a material can be calculated. Surface and subsurface flaws can also be detected with this method. Cracks, laminations, shrinkage cavities, bursts, flakes, pores, disbands and other discontinuities that produce reflective interfaces can be easily detected. There are two types of Ultrasonic Inspection.
- Ultrasonic Flaw Detection
- Ultrasonic Thickness Measurement
