Ultrasonic Testing (UT) is a precise, non-destructive method that uses high-frequency sound waves to detect internal flaws and measure material thickness, ensuring structural integrity across industries.
Ultrasonic Testing, also called Ultrasonic Flaw Testing or simply UT, uses high frequency ultrasonic waves to detect surface breaking and internal imperfections, measure material thickness and determine acceptance or rejection of a test object based on a reference code or standard. Flaw detection is a fast and accurate inspection method to evaluate internal product integrity. Ultrasound penetrates deeply into materials searching for defects, cracks, delamination, lack of bonding and other discontinuities.
EWF Group has decades of experience in applying UT inspections across all industrial sectors. EWF Group has full range of portable ultrasonic flaw detectors (UT) which provides leading-edge capabilities for locating discontinuities and other flaws and thickness gauges for the accurate measurement of nearly any material.

UT is a non-destructive method that uses high-frequency sound waves (typically 0.5–20 MHz) to evaluate material thickness or detect internal defects in objects without damaging them
A transducer sends ultrasonic waves through a material; flaws like cracks or voids reflect these waves back or attenuate them, and the reflected signal indicates defect presence and location
UT is highly versatile—it’s used on metals (steel, aluminum), polymers, composites, ceramics, and even concrete, though it performs best on homogeneous materials .
UT is widely used for inspecting welds, measuring corrosion, and evaluating structural components across aerospace, oil & gas, rail, marine, automotive, and construction sectors
Yes, UT is a non-destructive and non-hazardous method that uses sound waves, not radiation, making it safe for both technicians and the tested materials.
In many cases, no. UT can be performed on-site and even during normal operations, depending on the component and safety considerations.
