Electromagnetic NDE Techniques for Inspecting Composite Materials and Additively Manufactured Components
It is vitally important that as new manufacturing technologies and new types of materials emerge, we have to have viable alternatives for inspecting the resulting product nondestructively. New materials such as composites are increasingly finding their way into aerospace, energy and automotive industries. Likewise, additive manufacturing technologies are penetrating critically important sectors of our economy. This paper explores the use of electromagnetic techniques for characterizing damage in composite materials and describes a process control tool that is capable of detecting defects in additively manufactured components.
The presentation will first focus on an electromagnetic NDE technique that employs a multi-sensor probe for characterizing damage in components made of composites which are inherently anisotropic, has complex structural geometries, and are designed to operate in hostile environments. Second, we describe a multi-frequency EM sensor with a built-in calibration system and super-resolution capability for detecting defects in additively manufactured metal components during the manufacturing process.

R&D of NDT Technologies for Nuclear Power Plant and Applications
To ensure the safe operation of nuclear power plants, regular in-service inspection is an vital guarantee measure required by regulations. The NDT technologies used in in-service inspection of NPP mainly include: ultrasonic testing, radiographic testing, eddy current (electromagnetic) testing, penetrant testing, magnetic particle testing, visual testing and leak detection technology et al. In addition to the general introduction of NDT technologies for NPP, the applications of the eddy current (electromagnetic) testing technique, such as the ECT of the steam generator tubes, the thimble tubes for neutron flux measurement and ECT of bolts and nuts will be emphasized in this invited lecture.
