NDT TOPIC Abstract	This Month's Articles inludes an update of JUNE '98 ISSUE - RAILWAY INSPECTION
NDT Ethics UT Railway Railroad - Wheels	Summary of NDT response to the train accident NDT work also needs awareness of ethics; in the Summary we will clarify what happened in the media and why NDT.net got so deeply involved. Forum: NDT of railroad wheels at the German Bahn AG A Summary of the Forum discussion. We will comment and summarize 11 of the 33 forum discussions on this topic. Forum: Railroad Wheel Testing of Shattered Rim Todd Snyder's technical note received attached to his forum messages. He had spent the last six months analyzing cracks in railroad wheels using ultrasonic,magnetic, acoustic, and destructive metallurgical techniques. Todd Snyder, Union Pacific Railroad R&D Lab.
UT Railway Railroad - Wheels	Ultrasonic Assessment Of Residual Stresses In The Rim Of Railway Solid Wheels Tensile stresses of unsafe magnitude can be occasionally found in the rim of railway wheels, as a result of drag-braking under severe conditions. Such stresses are an hazard for human, environmental and economical reasons, since they may drive cracks up to wheel failure. Railway organizations and wheel manufacturers thus pointed out the demand for an NDE method enabling the non-invasive assessment of rim residual stresses. M. Gori, M. Certo, G. Patelli, L. Aruta; Itali
UT Railway Wheels	Transcript: Ultrasonic Evaluation of Stresses in the Rims of Railroad Wheels E. Schneider's (IZFP) speech at the 7th ECNDT Copenhagen 26 - 29 May 1998. The Article. This work has been done in cooperation with the German railroad (Deutsch Bahn AG) - you can see here its more or less final results.
UT Railway Wheels	Wenn im Rad die Spannung steigt ... Auch Güterwagenräder müssen zur Inspektion, weil Spannungen und Risse am Radstahlzehren. Für den Sicherheits-Check haben Fraunhofer-Techniker neue Ultraschall-Verfahren und Prüfgeräte entwickelt. Aus dem Archive: Der Fraunhofer 2/1996. Ein Magazin über die Fraunhofer-Forschung.
UT Railway Wheels	Computergesteuerte Ultraschall-Radsatzprüfanlage - Ein Beispiel Für Ein Neues Innovatives Prüfsystem Der mechanisierte Radsatzprüfstand AS-200 dient der Überprüfung von Ei-senbahnrädern, speziell der Laufflächen und der Radkränze. Eine Radsatzwellenprüfung kann optional ergänzt werden. G. Vogt, C. Köhler, Vogt Werkstoffprüfsysteme, Burgwedel. Annual DGZfP Conference '95 in Aachen.
Quality NDT Rail Welds	Quality Evaluation Methods for Rail Welds in Japan The subjects concerning rail welding processes in Japan are as follows: the application of GPW is expanded in Japan and/or overseas, and the reliability of the welds by fusion welding is promoted. And then, quality evaluation mechanism of GPW and improvement of reliability for fusion welding have been investigated. Railway Technical Research Institute, Kokubunji, Japan. Papers of RTRI at the WCRR'97 - World Congress on Railway Research in Florence, Italy
NDT Archive Reliability Validation	Determination of Reliability and Validation Methods on NDE Some articles of the Proceedings of the European-American Workshop, June 18 - 20, 1997 Berlin, Germany. Preface by Dierk Schnitger, President of DGZfP
NDT Reliability Validation	Strategies of Validation in General Testing compared to Experience in NDE Open questions in common understanding of the terms reliability and validation. This paper reviews the differences between "detection" and "measurement" in more detail, and discusses several alternatives for dealing with the validation of NDE methods which are based mainly on already existing experiences in several sectors of industry. Christina Nockemann, Carsten Bellon and Sylke Nickisch, BAM Berlin, Germany. European-American Workshop Determination of Reliability and Validation Methods of NDE, June 1997 Berlin, Germany
NDT Reliability Validation	Modelling of NDT Reliability (POD) and applying corrections for human factors Inspection by non-destructive testing techniques is not perfect and it has become common practice to quantify the reliability of flaw detection in terms of the probability of detection (POD) and the probability of false indication (PFI). Methods are discussed for correction of model data for human and environmental effects to give POD predictions now comparable with those obtained in experimental trials. M. Wall, F. A. Wedgwood, S. Burch, AEA Technology, Abingdon, UK
NDT Reliability Validation	The Current Status Of Performance Demonstration And Evaluation Developments Whenever the NDT plays a significant role in Saftey, the need to assess and demonstrate the performance of the NDT techniques applied to specific components is increasingly being required as a necessary precursor to the use of those methods. This paper describes the status of performance demonstration requirements for the nuclear industry world wide. It also reviews the current position regarding performance assessment for non-nuclear components. Chris Waites and John Whittle, AEA Technology, Risley, UK
UT Robot	Robot System for Ultrasonic Examination of Complex Geometries With the development and introduction of a new complete 3D ultrasonic inspection system FORCE Institute enlarges the inspection possibilities and increases the overall quality of UT inspection of complex geometry components. Lars Vesth, Peder B. Hansen and Willy Damgaard Kristensen FORCE Institute, Brøndby, DK
UT Simulation Modeling	NDT Related Quantitative Modeling of Coupled Piezo electric and Ultrasonic Wave Phenomena This paper presents an overview of the development of numerical tools for the computational modeling of acoustic, elasto dynamic, and coupled piezo electric and ultrasonic wave phenomena in the time domain related to nondestructive testing with ultrasound. R. Marklein, University of Kassel, D
VT Laser	Applications Of Laser Profilometry For Boiler Tube Inspection Laser-based profilometry inspections systems, used either alone or in conjunction with complementary technologies, show significant promise of benefit to plant operators. Laser profilometry is considered one of the cornerstones of laser methods in nondestructive testing. This paper presents an overview of this rapidly growing NDT method and provides examples of recent industrial applications. Richard D. Roberts, QUEST Integrated, Washington, USA
VT Laser	Remote Inspection Tool Developed To Provide Inspection For Complex Serpentine Furnace Tube Configurations An autonomous inspection tool has been developed by QUEST Integrated, Inc. that employs the combined capabilities of high-speed laser and advanced ultrasonic wall thickness measurements. Richard D. Roberts, QUEST Integrated, Washington, USA

ECNDT'98 Exhibition We provide news and snap shots at: AIPnD, Force, Imasonic, IRT, Karl Deutsch, Krautkramer, Metalscan, Nukem, Panametrics, QMI, RDTech, Yxlon, NDT.net Survey on Ultrasonic Flaw Detectors characterizations is still open After we received already 60 responses the final statistics was planed for this issue. Due to recent priorities we need to postpone this to the August issue. That means you can still add your opinion to a larger database and win an NDTnet 97-96 CD-ROM! NDT Innovation Prizes The NDT Innovation Prize, financed by Cegelec, is awarded in 1998 in partnership with the 7th Congress for Non-Destructive Testing, held in Copenhagen. International Innovation Award to FORCE Institute The European NDT Innovation Committee has selected FORCE Institute's work "3D Inspection System" as the winning contribution in the field of applications research work within the area of Non Destructive Testing. ICNDT Meeting in Copenhagen Philips and Andrex announce their merger and the formation of, YXLON International. YXLON International is the world's leading supplier of industrial x-ray equipment for non-destructive testing, with the most comprehensive range of products, from portable x-ray units to fully automatic systems.
