Introduction to Phased-Array Ultrasonic Technology

Phased-array ultrasonic technology has been used only recently for nuclear NDE applications. This SI Webinar introduces basic phased-array technology, operations, and several current nuclear applications, including examination of weld overlays and dissimilar metal welds. The Webinar addresses linear phased-array probes, sound field formation, focal law inputs, and touches on future specialty phased-array examinations in the nuclear industry.
