What is Phased Array Ultrasonic Inspection
Phased Array Ultrasonics (PAUT) is an advanced ultrasonic technique that permits the shaping and steering of the ultrasonic beam angles, dynamic depth focusing and enhanced beam coverages. The Phased Array beam sweeps like a searchlight through the object, resulting in a recordable image that reveals defects hidden inside a structure or weld.
Why is Phased Array Ultrasonic Inspection used
Phased Array offers definitive advantages over conventional ultrasonics by providing imaging that can often produce more accurate results, and like most imaging techniques, provides a higher level of reproducible results while minimizing human error. Phased Array also allows for enhanced coverage of a given component or weld from fixed and multiple positions including achieving beam coverage on complex geometries where conventional ultrasonic techniques were inadequate.
