Ultrasonic Testing (UT)
Ultrasonic inspection is a nondestructive testing method that uses high frequency ultrasonic waves to detect flaws or determine thickness of materials through multiple techniques such as Pulsed Echo, Phased Array (PA), A-Scan, B-Scan and C-Scan.
Our knowledgeable and experienced technicians may perform a variety of inspections utilizing a range of methods for your specific applications such as:
- Wall thickness
- Inspection of welds/Flaw detection
- Lack of fusion
- Flaw sizing
- Corrosion mapping
- Defect characterization
Ultrasonic Thickness Testing (UTT) measures wall thickness by directing a straight beam on the surface of the material and measuring the reflected sound from the opposite surface. When calibrated for the known material, the two-way time of travel, divided by the known velocity through that particular material, provides a thickness measurement equally accurate to a micrometer reading.
Ultrasonic Shear Wave (A-Scan) testing detects flaws in materials by transmitting an ultrasonic wave at a specific angle into the material and measuring the reflected waves to calculate location and size of detected flaws.
