Ultrasonic Testing (UT)
Ultrasonic Testing employs high-frequency sound waves to navigate the inner landscapes of materials, mapping out subsurface defects with precision.
This NDT method provides critical information about the depth and size of flaws using beams of mechanical waves of short wavelength and high frequency, transmitted from a small probe in contact with the specimen surface and detected by the same or other probes. Ultrasonic pulses could indicate the presence, absence, and location of flaws, interfaces, and discontinuities. This technique determines thickness or reveals corrosion discontinuities near the surface or deep within components or structures. Applications include locating manufacturing defects in welds and castings through to corrosion/erosion monitoring and large-scale corrosion mapping, making it essential for a thorough material evaluation.
