Özet

Reliability and the reproducibility of results have always been an important concern in non-destructive inspection (NDI). This is especially the ase if the component is critical and has to be inspected periodically. If components are to be examined by Eddy Current Testing (ECT), the test procedure must take into account all the related parameters such as lift-off, geometry, possible conductivity and permeability changes on the test surface as well as the operator dependence. The utilisation of easy to manufacture and specially designed adapter blocks help reduce these difficulties. In this study, alternative ECT procedures using various adapter blocks are prepared for three types of aircraft components with complex geometry. These procedures require a simple meter display instrument and absolute pencil probes, which is the available instrument at the source location of these components.
