INTRODUCTION & BASIC INFORMATION
Phased Array Ultrasonic Testing (PAUT) is an advanced nondestructive examination technique that utilizes a set of ultrasonic testing (UT) probes made up of numerous small elements, each of which is pulsed individually with computer-calculated timing. more complex geometries that are difficult. PAUT can be used for more complex geometric weld inspections, high thick materials and crack detection. Advantages are, it can be conducted more quickly, used for repeat scans because it has a high degree of repeatability, it is able to create detailed and accurate cross-sections of a part, gives a permanent record, Gives information about lateral position of defect in weld (depth and height), No radiation, higher POD.
APPLICATION
PAUT is widely used in Oil & gas, nuclear Industries (Refinery’s, Petrochemicals of piping, boilers, pressure vessels, clad material, Storage Tanks, In-service weld inspection including Stress Corrosion Cracking, Complex Geometries – Nozzles, Flanges, Shafts, bolts)
