Phased Array Ultrasound Testing (PAUT) is a type of non-destructive testing (NDT) technique that uses ultrasound to inspect materials for defects or anomalies. In PAUT, multiple ultrasound transducers are combined in an array and used to scan the material simultaneously, providing a faster and more comprehensive inspection than traditional ultrasonic testing. The use of phased arrays allows for the real-time adjustment of the direction and focus of the ultrasound beam, making it possible to inspect complex geometries and multiple angles in a single pass. PAUT is widely used in various industries including aerospace, power generation, and oil and gas. It is also particularly useful in situations where there is less room for mechanical scanning because it’s able to sweep the beam without moving the probe.
Time of flight diffraction (TOFD) is a non-destructive testing (NDT) technique used to detect and size defects in materials such as metal plates and pipes. It works by transmitting ultrasonic waves into the material and measuring the time it takes for the waves to travel to the defect and back. The resulting waveform is analyzed to determine the location and size of the defect. TOFD is highly accurate and provides a fast and reliable method for detecting defects in structures that are difficult to inspect using other NDT methods, such as those with complex shapes or heavy corrosion. It is widely used in the petrochemical, nuclear power, and shipbuilding industries, among others. High Accuracy: TOFD is known for its high accuracy in detecting and measuring defects, making it an effective tool for quality control and inspection.
A borescope or videoscope is an optical inspection tool used for non-destructive testing and evaluation. It can eliminate the need for man-entry and often requires much less preparation than man-entry.
