USL adds Eddy Current Testing (ECT) to its repertoire

Building on expertise in robot motion control and experience within the aerospace and NDT industries, USL has developed an eddy-current test cell to meet industry needs. Available as a purpose-built, self-contained cell for the inspection of life-limited rotating engine components (as pictured), an application specific system or an addition to a USL UT system. Utilising the latest Stäubli robots and state-of-the-art controller, functional safety features allow for reduced perimeter guarding requirements and a more collaborative application between user and robot.

Surfaces and structures of materials used in the industry are often vulnerable to corrosion and damage caused by long term use as well as natural factors, resulting in a range of defects. Periodic inspections are vital to ensure their integrity. Eddy current testing can be applied in the detection of these defects by analysing and processing the changes caused by the physical properties of the material without damaging the structure. Eddy current testing is based on the principle of electromagnetic induction which is mainly applied to the surface and near-surface testing of conductive materials. Defects are discovered by detecting a change in the induced eddy currents in the measured objects. Compared with other NDT techniques, eddy current inspection has the advantages of fast detection speed, easy operation and high sensitivity, often without a coupling medium.
