What is Phased Array Ultrasonic Testing?

Phased Array Ultrasonic Testing (PAUT) is an advanced ultrasonic testing technique that uses multiple ultrasonic elements in a single probe to generate and receive sound waves. By controlling the timing and amplitude of the signals sent to each element, the beam's shape, angle, and focal distance can be electronically steered and focused. This allows for rapid scanning of a material and the creation of detailed cross-sectional images to detect flaws, measure thickness, and characterize materials. It is commonly used for inspecting welds, detecting corrosion, and examining complex geometries.
