Automated Ultrasonic Testing (AUT) has begun to surpass traditional radiography as the preferred approach for pipeline weld inspection around the globe. Significant limitations exist in radiography, including inadequate detection of planar faults, lack of vertical scaling capability, safety and environmental concerns.

AUT comprises various techniques and technologies, such as phased array ultrasonic testing (PAUT), rapid ultrasonic gridding (RUG), time-of-flight diffraction (TOFD), and pulse echo weld inspection, but not restricted to these.
