Phased Array Ultrasonic Testing

Phased Array technology allows for electronic modification of the acoustic probe characteristics. This is achieved by introducing time shifts in the signals transmitted to and received from individual elements of the array probe. Phased Array can be applied to any ultrasonic technique used for flaw detection and sizing. Phased Array offers several advantages, including high-speed electronic scanning without the need for moving parts. It enhances inspection capabilities by allowing software control over beam characteristics, enabling inspection with multiple angles using a single electronically controlled probe. This technology supports various configurations such as P/E (Pulse-Echo), T/R (Transmission/Reception), TOFD (Time of Flight Diffraction), and Tandem, providing greater flexibility for inspecting complex geometries through optimized focusing and beam angle adjustment. Phased Array is widely used in various industries, including raw material production, aerospace, naval, power generation, petrochemical, and any other sector that currently utilizes pulse-echo testing.
