UniWest announced the introduction of the new EddyView® II portable eddy current flaw detector at the ASNT Annual 2022 Conference on October 31, 2022.

In production, every aircraft structure component will undergo inspection by one of the primary NDT methods. In-service aircraft will experience subsequent nondestructive testing, eddy current inspection being one the primary methods. This article serves to highlight the more common forms of eddy current applications on in-service aircraft.

Nondestructive testing methods range from simple manual and visual techniques to sophisticated eddy current and ultrasound technologies that can be used for spot-checks or incorporated right into the production line.

To a qualified and well-equipped nondestructive testing technician, few inspections present an insurmountable technical hurdle. Technicians have a range of testing methods at their disposal, from sophisticated ultrasound and eddy current technologies to manual processes like liquid penetrant.

NDT has become a critical necessity in order to meet the demanding requirements from users of high-quality round stock bar and tube.

Aero-engine discs are very critical parts since they are exposed to high stress and temperature during flights. Engine disc components such as bearing rings, fan and compressor discs are subjected to extensive inspections during the different manufacturing stages, including dimensional controls up to the detection of the tiniest surface flaws on rolling surfaces (bearing raceways).

First, a little history. The alternating current field measurement (ACFM) nondestructive testing technique was developed in the ‘80s to detect and estimate penetration depth of fatigue cracks in underwater welded tubular intersections of offshore oil platforms.
