Phased Array PA

Phased Array PA

A single phased array probe can simulate many different conventional probes. The ultrasonic beam may be both steered (change of angle), focussed and scanned without moving the probe. Sound beams of many angles can be generated sequentially, inspecting a large portion of the component’s cross-section.

To achieve this same coverage using conventional techniques, multiple probes would have to be moved over the component’s surface. Advantages of the phased array are that it allows inspection of complex geometries with a single probe and scan times are greatly reduced. The image below shows a 45 to 70 degree scan of a butt weld. The red areas on the C-Scan view are from lack of fusion defects.

IRISNDT have both the RD-Tech Omniscan and the Focus Phased Array Systems
