ABSTRACT
The ultrasonic wave visualization system was developed to investigate waves propagation in austenitic stainless steel welds for ultrasonic testing of welded joints. This system consists of a conventional ultrasonic flaw detector, scanning unit, synchronized unit and signal-processing computer. The double transducer technique using synchronized transmitted wave was applied; the receiver was scanned and signal was received at the side of the specimen. These received signals were computed and imaged to C-scan display. This image shows ultrasonic wave front propagating in the specimen. The ultrasonic wave propagation in the specimen could be visualized with varying delay time. This visualization system was applied to investigate ultrasonic longitudinal wave propagation in austenitic stainless steel welds and wave front propagation in welded joints was obtained.
