This Month's Introduction

This month we are pleased to  present all Abstracts from the WCNDT '96 New Delhi. Even though the publication is from 1996 the content is  not out of date.  We are hoping  to publish the WCNDT 2000 abstracts, too, and to sponsor a searchable CD-ROM for all participants.  We will keep readers informed of developments. This month's articles cover a broad spectrum of NDT subjects, such as NDT in Reactor Safety, NDE's reliability, NDT in Civil Engineering, NDT methods of Welding, Endoscopic Shearography, Thermography. We hope the content will serve as a useful online resource for many readers. German readers may be interested in the Comprehensive Program of DGZfP's annual NDT conference in Celle, May 10.- 12. 1999 - it's not too late to register!

NDT TOPIC	This Month's Articles
Energy Safety Risk	Status of NDE Research in the US--Contributions of NDE to Reactor Safety and Implementation of NDE Technology The main conclusion to be drawn from the examples given in this paper is that assessment of the contribution of NDE to reactor safety requires careful analysis, and is not immediately obvious. Frank Ammirato, EPRI, Charlotte, NC, USA
Quality Weld	Selection of an NDT Method and the Extent of Testing Each testing of welded joints should start with the selection of a suitable testing method and determination of the extent of testing. The selection of a testing method and determination of the extent of testing are as important as testing itself when the final result is considered. Gabriel Rihar, D.Sc., Institut za varilstvo, Ptujska 19, Ljubljana.
Reliability	Erratic Measure The paper exposes an inconsistency in the field of non-destructive examination (NDE) and points out the dangers of the confusion which is created by it. Terry Oldberg, Consultant, Los Altos Hills, California; Ronald Christensen, Entropy Limited, Lincoln, Massachusetts.
Impact-Echo Radar UT Civil Eng.	Combined NDT for system assurance in railway construction: Impact Echo, Ultrasonic and Radar techniques An example is reported of combined application of NDT techniques on an innovative railway system. C. Colla, B. Milman, J. Wöstmann, F. Mielentz, J. Henschen, H. Wiggenhauser, Bundesanstalt für Materialforschung und -prüfung (BAM), VII.3, Berlin.
Impact-Echo Civil Eng.	Automated Impact-Echo: 2- and 3-D Imaging of Concrete Elements The results clearly show the advantages of scanning over point measurements. They unambiguously prove that Impact-Echo can lead to wrong results when point measurements are used for interpretation. C. Colla, G. Schneider, J. Wöstmann, H. Wiggenhauser, Bundesanstalt für Materialforschung und -prüfung (BAM), Berlin .
Endoscopic Shearography Thermography	Endoscopic Shearography and Thermography Methods for Nondestructive Evaluation of Lined Pressure Vessels Endoscopic shearography allows the inspection of components such as lined fuel tanks which were previously difficult or impossible due to their closed structure. Endoscopic thermography will provide a means of nondestructively confirming endoscopic shearography indications and may have some applications for which endoscopic shearography is unsuitable. S.S. Russell, Marshall Space Flight Center MSFC; Alabama M.D. Lansing, University of Alabama in Huntsville, Alabama.
IRT	Infrared thermography and non destructive evaluation Thermal contrast prediction and defect parameter estimation in infrared thermography using artificial neural networks IRNDT: Integrated software tool for infrared image processing in JAVA Pulse phase thermography vs thermal tomography The report shows the Laboratory's activities in two fields: infrared vision (especially for NDE) and automated industrial inspection. Xavier Maldague, Annual Reports 1997-1998 of the Computer Vision and Systems Laboratory, Canada

Continuing  Railway Accidents Show the Importance of NDT Criticism of Deutsche Bahn safety policies continues in the wake of many accidents since January. Material defects, like broken cargo wheels or other technical defects are suspected in some of the 1999 accidents. New Apparatus Measures Thermal-Barrier Coatings Better NIST researchers in the Materials Reliability Division, Boulder, Colo., have developed an apparatus to measure the thermal conductivity of thermal-barrier coatings (known as TBCs) as thin as 20 micrometers. Fast Automated Ultrasonic Measurements As the NERASON 1090 reaches its final stage of testing, and soon will be available, the system performance and technical specifications are described in the article: "Fast Automated Ultrasonic Measurements" (Nuson's News). Highlights at the Phoenix's News Web Page: NP invests in phased array technology. New manipulator is hot stuff! Lightweight scanner an automatic success. The Panametrics Newspage has been recently updated New Homepage of ScanMaster Systems (IRT) Ltd. ScanMaster (formerly IRT) is a member of the Marmon Group, which is one of the largest privately held companies in the United States, based in Chicago. New Homepage of Structural Monitoring Systems Limited Developers of Advanced On-line Structural Monitoring and Warning Systems. The SMS System offers inexpensive, on-line monitoring of the formation and development of fatigue-related and other cracking of the critical parts of a structure the integrity of bonded joints.

UV Powerlight für NDT Systeme Laut Angaben der Firma Wotke GmbH ist dies die einzige im Handel befindliche UV Handlampe, welche die EN-60598-2-8 Norm erfüllt. Weichenstellende Technik fuer Schiene und Rad Sieben Fraunhofer-Institute praesentierten ihre aktuellen Forschungsergebnisse fuer die Schienenverkehrstechnik auf der Hannover Messe. Erklärung des Vorstands der Deutschen Bahn AG zu den aktuellen Unfällen im Bahnbetrieb This German Press Release states that safety has the highest priority. The DB started immediately after the Eschede accident to investigate its in-service inspection concept, which also involves aerospace experts of the Lufthansa. The DB AG intends to present railway safety report in 1999. Zwei mal fünfzig Jahre Ultraschall in Deutschland KRAUTKRÄMER und KARL DEUTSCH feiern gemeinsam ihr 50jähriges Firmenjubiläum während der DGZfP-Jahrestagung in Celle.
