This Month's Introduction
Try It This Month's Issue introduces a New Virtual Library, the world's largest collection of NDT marketing, science and education resources.  It is a truly comprehensive database of more than 600 servers including 12 000 documents. With its 300 commercial sites this Library is the most complete source of  NDT product and service information. Thanks to our NDTnet Exhibitors and Sponsors we can offer this service free of charge.  See our Press Release for more details.
Beginning with next month's issue our entire Exhibition will also become a database, and introduce a significant number of new services. NDT companies, click this link to our  Exhibition Registration to subscribe now and get  ready for lots of new business!

NDTnet Launches New Virtual Library
World Biggest NDT Resource!

Inspecting Welds for Creep Damage
AEA Technology Engineering Services, Inc. has recently completed inspection and project management at a series of electricity generating stations for a major US utility.

UT of Thin Welds and Friction Stir Welds
Ultrasonic phased array technology was chosen over standard ultrasonic inspection technology as it has proven to be very efficient in the inspection of FSW. (R/D Tech)

British Airways NDT Chooses ISONIC
Bond Testing and Mapping System for Concorde's Flying Surfaces (Sonotron NDT).

Ultrasonic Inspection and Mapping of Internal Glass Coating in Reservoirs and Reactors
A new technique was created to implement ultrasonic inspection of glass coating while scanning from outside with true to scale mapping of testing integrity and defects (Sonotron NDT).

Canspec announce the acquisition of Russell Technologies
Canspec Group Inc. provides materials testing, nondestructive testing and related services to the leading industrial concerns of Canada, and throughout the world.

Brochure of Automated Ultrasonic Imaging Systems
Conam's versatile ultrasonic imaging systems integrate microprocessor technology with nondestructive testing techniques.

Software for Computational Methods in Ultrasonics
CyberLogic's software package, named Wave2000, is now available and should be of use to engineers and researchers involved in several ultrasound fields, such as materials evaluation, flaw detection and imaging.

Uncovering hidden corrosion
New Ultrasonic tool offers safer inspection at pipe supports (Shell global Solutions)

SONIC IR - Breaking News!
Sonic excitation (~20kHz) of a part causes the interfaces of cracks in the part to rub against each other, thereby establishing a localized source of heat at the position(s) of the crack(s), delamination(s), "kissing" disbond(s), void(s), etc.. QuickTime movies illustrate the application of the technique. ( Thermal Wave Imaging Group, IMR)
