Phased Array Ultrasonic Testing (PAUT) is a focused inspection technique designed to incorporate beam technology to detect complex geometries & sizing defects.

Time-of-flight diffraction (TOFD) method of ultrasonic testing is a sensitive and accurate method for the non-destructive testing of welds for defects. TOFD originated from tip diffraction techniques which were first published by Silk and Liddington in 1975 which paved the way for TOFD.

Time of Flight Diffraction (TOFD) is a reliable method of non-destructive ultrasonic testing (UT) used to look for flaws in welds. … Like most UT methods, TOFD works by emitting sound waves into a component and measuring the time from them to return.

Phased Array Ultrasonic Testing (PAUT) is an advanced non-destructive 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. … Compared to other forms of UT, PAUT has several advantages.
