“…Dogaru and Smith [5] accentuated the outstanding performance of GMR-ET in terms of resolving defects near plate edges compared to conventional ET-coil systems. In further publications, they investigated the capability of the detection of small cracks [6] and together with C.H. Smith [7], they were able to detect hidden defects (ligaments up to 1.35 mm) using an adapted array probe with 16 GMR elements.…”

“…However, it should be emphasized that this last result were achieved mainly because the probe was permanently mounted on the specimen during the tests, and therefore the lift-off effect was eliminated. Others promising EC variants are GMR [11] and SQUID [12] sensors: the probe has a coil to generate the induced current in the test material, and GMR or SQUID as a sensing element. It has the advantage of a higher sensibility, even under low frequencies, but the lift-off problem still remains.…”

PREFACEThe rapidly expanding role of Non-Destructive testing and evaluation (NDT & NDE) methods in manufacturing, power, construction, and maintenance industries, as well as in basic research and development, has generated a large demand for practitioners, engineers, and scientists with knowledge of the subject. The Non-Destructive testing of materials is becoming more and more important, during the production process prior to building the constituent parts in individual devices and machines. It is becoming even more important in service inspection where the state of the material is checked and further safe operation of the device or machine is confirmed. Demands that each part built in machine is manufactured in a qualitative manner require from each manufacturer removing bad or rejected parts prior to selling them to buyers or building them in a device or a machine. Therefore demands are set up that manufacturers develop proper Non-Destructive methods, in corresponding devices and also experts with adequately verified knowledge. Especially for the reasons, in automated production, there often come demands that workpieces, namely machine parts are tested in a very short time while the method must assure respective reliability and also repeatability. The proceedings comprise papers presented at the 12th Int. NDT Conference held in Portorož, Slovenia from 4 to 6 September 2013. The conference was organized by the Slovenian NDT Society and Faculty of Mechanical Engineering, University of Ljubljana. The excellent scientific standard of the presented works, the presence of experts from 23 countries all over the globe and the inspiring venue of the Slovenian Adriatic Coast contributed to the success of the conference. The proceedings contain nine keynote papers presented by distinguished experts from the field, who I am grateful to for sharing their experties with us. The Scientific Committee reviewed 82 papers out of which 74 were presented at oral sessions and 8 at poster sessions. The presented papers discussed ultrasonic testing, electromagnetic, acoustic emission, thermal and infrared techniques and radiographic techniques, NDT education and training and other methods. The three-day event provided a forum for scientists, engineers and practitioners as well as endusers to review the latest developments, identify particular needs and opportunities for further advances, exchange knowledge and experience with other well-known experts as well as outlined the milestones for further progress in NDT & NDE fields. We are grateful to...

“…There are three major criteria in choosing the suitable magnetic sensor; low field operating range, wide operating frequency, and small dimension in order to obtain high spatial resolution. Therefore, SV-GMR sensor is suitable for NDE application because of aforementioned performance [3]- [5].…”

Abstract-This paper describes the applications of spin-valve type giant magnetoresistance sensor (GMR) for nondestructive evaluation. One is the eddy-current testing (ECT) probe which enables us to inspect micro defect and to detect micro conductors. The proposed ECT probe was applied to the inspection of bare printed circuit board and the recognition of micro solder bead for IC surface mounting package. Another is the measurement of the density of magnetic fluid injected in living body for the hyperthermia treatment. For this purpose, the needle type GMR probe was developed. The experimental results verify the possibility of the proposed system.
