PHASED ARRAY ULTRASONIC TECHNIQUE (PAUT) चरणबद्ध सरणी अल्ट्रासोनिक तकनीक (PAUT)

PHASED ARRAY ULTRASONIC TECHNIQUE (PAUT) This video has been explained features of Phased Array Ultrasonic Technique (PAUT) and its working A new technique of Phased Array ultrasonic testing (PAUT) is being used for weld testing by some of the World Railways. Phased Array Ultrasonic Technique (PAUT) is an advanced nondestructive ultrasonic technique that permits the shaping and steering of the ultrasonic beam angles and enhanced beam coverage. The Phased Array beam sweeps like a searchlight through the object, thus more sensitive in detecting the defects compared to conventional UT. For determining the adequacy and suitability of PAUT weld tester, RDSO has been conducted field trials and satisfied with results. On the basis of performance of PAUT weld tester and outcome of the field trials following advantages have been observed: 1 No need to change the probe for different angles in Phased Array ultrasonic weld tester. 2 It is capable to detect the unwanted fins at different orientation which cause the stress concentration in the weld. 3 It displays the defect in various forms i.e. A-Scan, B-Scan, C-Scan & S- Scan for better analysis. 4 It displays the defect location more accurately. 5 It has mechanized probing. 6 It displays the decoupling between probes and probing surface. 7 Phased Array ultrasonic beam sweeps like a searchlight through the object with varying angles from 36 to 76 degrees, resulting in a recordable image that reveals the defects inside a rail or weld. 8 PAUT system permits the shaping and steering of the ultrasonic beam angles and enhanced beam coverage. 4 S-Scan: this is a sector scan which is produced when a phased Array is used to electronically sweep an ultrasonic beam through a range of angles. It shows a two-dimensional view of all amplitude and time or depth data from all focal laws of a Phased Array probe, corrected for delay and refracted angle. 3 The PAUT weld tester should have mechanical scanner to ensure the installation of probes in the zone of welded joint and movement along the weld. 4 The PAUT weld tester should have multichannel continuous recording of flaw detection information for the FB welded joints in real time. 5 Angle of steering of the ultrasonic beam of PAUT through the object should be from 360 to 760 and frequency of PAUT weld tester probes should be between 2 to 5 MHz.
