PHASED ARRAY ULTRASONIC TESTING (PAUT)
Phased array ultrasonic testing (PAUT) can be used for multitude of tasks. Today in assessment of structures, flaws, fitness for use of the product or equipment and assessment of critical parts require flaw data regarding to location shape and size of the defect.PAUT can provide an accurate assessment of defect and material fracture analysis based on the acceptance standards.
PAUT is used to detect defects that cant be easily detected using conventional volumetric methods such as radiography and manual ultrasonic testing. ANDT specializes in providing PAUT support in petrochemical industries, oil and gas, power, chemical industries.
A PAUT probe is made up of multiple small ultrasonic probes which can be fired individually. By varying the time of the pulse of each probe ultrasonic rays can be steered into various angles and focal distances. Therefore wave can be swept across the material and thereby covering the object.
Applications for Phased Array Ultrasonic Testing
- Inspection of forging or casting materials
- Weld inspection
- Corrosion mapping
- Scanning complex geometry
