This Month's Introduction

Breaking News! NDTnet Launches New Robot - Content retrieval now faster, better than ever before! Our Virtual NDT Library Database is now powered by a huge number of remote NDT Pages. Every day, our robot combs cyberspace, building this new NDT Internet Search Engine. See our separate Introduction of this new feature. Also new is the Power Search for our articles database which let you easily retrieve comprehensive information. We use the Robot for our Exhibitors' Homepages too. This and other new extras for sponsors make advertising on NDTnet much more valuable than old-fashioned "piece of paper" ads. NDT Products are just a mouse click away! See our News on Advertising here With this month's issue we complete our special series on the ECNDT '98 with a spectrum of papers from all sessions. However, due to some authors' schedules, we may still publish late arriving e-files in 1999. A few papers may not arrive at all. Some German institutions/authors decided to boycott NDTnet in protest of our report on this summer's German train accident. We'll have more to tell you about that development in our DGZfP Bamberg '98 report next month. Control of the Internet? Ethics in NDT? Thanks to the Slovenian NDT Society, we are pleased to provide the complete Abstracts of the Proceedings of the 1997 International NDT Conference.

Air-coupled Ultrasonic Testing	_______________ Nondestructively Inspect Material Integrity With An Airborne Ultrasonic Beam The CURLIN-AIR was initially developed to ultrasonically inspect an evergrowing class of materials/products that are too attenuative to inspect with conventional (Megahertz frequency) ultrasonic flaw detectors. However, because of its noncontact airborne beam feature, CURLIN-AIR, also, offers applications advantages for certain materials/products (Samples) that are routinely inspected with conventional equipment. The object of this Tech Note is to briefly explain, in simple and general terms, how & why it works. Technical Note by NDT Systems, Huntington Beach, CA, USA
