Phased array ultrasonic testing (PAUT) uses the principle of wave physics to generate and receive ultrasonic beams by varying the time between pulses from multiple ultrasonic elements:

Pulse timing

The time between pulses from each element in the array is varied to create constructive and destructive interference. This allows the energy to be focused at any depth and angle in the test material.

Beam steering

The beam can be electronically steered and swept through the test material like a searchlight by changing the time delay.

Image creation

Multiple beams are combined to create a visual image that shows a slice through the test object.

PAUT has many advantages over traditional ultrasonic detection, including:

Higher detection speed: PAUT is faster than traditional ultrasonic detection.

Higher sensitivity: PAUT has higher sensitivity than traditional ultrasonic detection.

Increased flexibility: PAUT is more flexible than traditional ultrasonic detection.

Improved efficiency: PAUT can capture hundreds of signals at once, which makes it easier to characterize defects.

Reduced false alarms: PAUT reduces the number of false alarms.

PAUT is used in industrial inspections for inspecting welds, pipelines, and critical components. It can also be used in medical diagnostics for early detection of medical conditions.
