Phased Array Ultrasonic Testing (PAUT)
Phased Array Ultrasonic Testing (PAUT) is an advanced ultrasonic testing technique used to detect and evaluate internal indications and discontinuities. It provides detailed inspection results and supports reliable quality control, safety and asset integrity.
What is Phased Array Ultrasonic Testing?
Advanced ultrasonic inspection with precise results
Phased Array Ultrasonic Testing (PAUT) is an advanced application of ultrasonic testing that uses multiple individually controlled elements to generate and steer ultrasonic beams through a material. By electronically controlling the angle and focus of the beams, PAUT can inspect larger areas and complex geometries with high accuracy.
The technique can be used to detect and evaluate indications such as cracks, lack of fusion, lack of penetration and other weld discontinuities. Inspection data can be displayed as detailed cross-sectional images, providing valuable information about the location and size of indications.
PAUT is widely used for weld inspection, corrosion mapping and the examination of complex components in industrial and offshore environments.
Benefits
- Detailed inspection data with accurate indication positioning
- Electronic beam steering and focusing for efficient inspection of complex geometries
- Imaging capabilities provide a clear visual representation of inspection results
