Ultrasonic Flaw Detectors
Ultrasonic flaw detectors emit high-frequency sound waves that reflect flaws and create echo patterns, revealing hidden cracks, voids, porosity, and other irregularities in a variety of materials and structural components; then recording the echo patterns of their reflections. While similar to eddy current flaw detectors, the two types of equipment use different technology to perform their tests.
There are two basic types of ultrasonic flaw testing: straight beam and angle beam.- Straight Beam Testing: Sends sound waves directly into the structure under test. By analyzing these readings, an operator can get a clear picture of any faults within the structure.
- Angle Beam Testing: Finds faults perpendicular to the flaw detector by sending sound waves into the structure at an angle.
