What is Ultrasonic Testing?
Ultrasonic Testing uses high-frequency sound waves to detect internal defects and measure material thickness.
Overview
Ultrasonic Testing (UT) works by sending high-frequency sound waves into a material. When the sound hits a defect or the back wall, it reflects back to the probe; by timing these reflections, an inspector can locate flaws and measure thickness.
UT can find deep internal defects that surface methods miss, making it invaluable for weld inspection and corrosion monitoring.
What UT Detects
- Internal cracks and lack of fusion
- Laminations and inclusions
- Wall thinning from corrosion
- Weld volume defects
