Phased Array

Today ARL uses phased array technology for weld and material testing. The object is to increase the economic value of inspections by decreasing inspection time and simplifying the scanning hardware, increase the quality of testing while matching or exceeding the flaw detection and sizing capability of conventional ultrasonic technique

Array probes consist of 16 and 32 elements and a single array probe can be made to simulate many different conventional probes, without moving the probe sound beam of may angles can be generated sequentially, able to inspect large portion of the component’s cross section.

Array probe have to move over the component parallel to weld or item under test to achieve full coverage.
