Abstract: A lot of progress is made in the last decade concerning the theoretical and practical aspects of eddy current testing. In addition to the defect characterization, actual studies deal with the metallurgical evaluation of materials. Surface examination allows the prediction of the material strength and consequently its life time. In order to obtain various microstructures and to modify ...

In this contribution a force measurement system will be represented. It applies the method of eddy-current sensor testing. This measurement arrangement is able to detect dynamic tensile loads in prestressings, which are higher then 5 MPa and oscillating up to 20 Hz. Fast measurement rates and low power consumption are the main efforts of the eddy-current sensor system. Developed sensor-arrays c...

Systems that associate positions with eddy current probe readings present inspection data more directly and usefully than the more common impedance plane display. We have economically constructed such an integration of an eddy current testing device with a position feedback device which gives 0.005” achievable resolution. The position and probe readings are fed to a PC and plotted in real-time ...

Eddy current testing is an effective way of detecting fatigue cracks and corrosion in conductive materials. The cost of using the technology is low, and the devices can monitor subsurface defects and defects under insulating coatings without touching the surface of the specimen. Although this technique is applicable for many tasks, the aircraft and nuclear power industries are the primary users...

The use of the eddy current technique (ECT) for the non-destructive testing of conducting materials has become increasingly important in the past few years. The use of the non-destructive ECT plays a key role in the ensuring the safety and integrity of the large industrial structures such as oil and gas pipelines. This paper introduce a novel ECT probe design integrated with the distributed ECT...

Multi-information fusion is the trend of NDT equipments. This paper describes the principle, configuration and application of EMS-2003 —– a new device combining metal magnetic memory, eddy current and magnetic flux leakage testing techniques. By using the three complementary NDT techniques, we are able to make complete testing and analysis on early damages and established defects in in-service ...

This section contains a review of physical fundamentals and results of practical implementation of methods of nondestructive testing (NDT) and evaluation. It also presents relevant information on magnetic, electrical, eddy current, HF electromagnetic, infrared, optical, acoustic, radiographic, penetrant and other (such as vibration, leakage testing and integrated) methods of NDT and evaluation ...

In this paper, the evaluation of the characteristics of a new type rotating eddy-current probe for nondestructive Eddy-Current Testing (ECT) is carried out using 3-D edge-based FEM. The changes of the induced electromotive force are monitored for various inner and outer types of thin cracks inside the metal plate. It was veri ed that although the intensity of the signal obtained by this new typ...

Abstract Non-destructive testing and complex systems integration are commonly used in transportation, aircraft, automotive, manufacturing, petrochemical, defence. Eddy current (ECT) is a common non-destructive evaluation technique, especially the coating, nuclear, oil gas industries. However, eddy method must continue to focus on probe’s construction application. It ascribed noisy data inadequa...
