What is the main purpose of employing a phased array system in NDT?

The main purpose of employing a phased array system in non-destructive testing (NDT) is to enhance the quality and versatility of inspections. Phased array technology allows for the manipulation of sound beams in multiple directions without the need to move the transducer itself. This capability enables inspectors to capture detailed and accurate data from complex geometries and varying materials, providing better insight into the integrity of components being tested.

In addition to improving the thoroughness of inspections, phased array systems offer the versatility to adapt to different testing scenarios. This adaptability includes adjusting the beam angle, focal depth, and other parameters dynamically during the inspection process. As a result, inspectors can optimize their approach based on specific application requirements, which leads to an overall improvement in detection capabilities and flaw characterization.

While increasing manual inspection speed and reducing costs may be benefits associated with automation and advanced technologies in NDT, the central focus of phased array systems is on enhancing the quality and versatility of inspections to provide reliable results. Limiting access to scanned areas is not a characteristic of phased array systems; in fact, they are designed to efficiently evaluate areas that may be difficult to inspect with traditional methods.
