This Month's Introduction
Article: Signal conditioning algorithms in acoustic emission analysis using wavelets
Signal conditioning is one of the most important issue in AE Testing.

This month's issue focuses on Acoustic Emission. With its 16 presented papers along with our Discussion Forum and Exhibition this comprehensive issue serves like an online conference. Also we are pleased to present the new AE Chapter in our NDT Encyclopedia together with an AE Quiz - Basic Level .

Dr. C. Grosse
Thanks to Dr. C. Grosse who works on the NDT.net Editor Advisory Board and coordinated this issue.
Also we wish to thank authors for all their co-operation.

German train crash: Three on trial because they did not apply ultrasonic testing
Carelessness in introducing a new type of wheel to the high-speed train. When ICE began operations it was committed to use ultrasonic testing every 250.000 km operation, in fact no appropriate testing method was developed for in-service inspection.

Checking weld spots during the welding process
VOGT Werkstoffpruefsysteme GmbH, Burgwedel/Germany, has launched on to the market a further development relating to the non-destructive testing of resistance weld spots.

New Inspection Service Capability
Metals Testing Company receives Rolls-Royce approval for providing Ultrasonic Inspections

U.S. NDT Market Growth Continues
Maxtech International's New Survey of Users Indicates Optimism.

PUNDITplus ultrasonic pulse velocity test instrument
CNS Farnell upgrade world-beating PUNDITplus instrument

Sira's miniature radiation hardened CMOS camera passes the test
A miniature radiation-hardened nuclear industry inspection camera designed & built by Sira Electro-Optics Ltd, has passed a test of surviving 6 Mrad(Si) of cobalt60 gamma ray irradiation with no detectable loss of performance.

Risk-Based Inspection & Maintenance Planning Software
As part of its services to the oil & gas, petrochemical, chemical and power industry, TWI is currently offering operators and suppliers its RISKWISE" risk-based maintenance software.

UT Simulation Program
The program offers a simple simulation of the Ultrasonic testing process. Its not fancy but may be of use to somebody. It can be downloaded for free.
