The Weekly IRC #NDT is a newly established NDT real-time discussion
channel. Here is the record for a former topic:
IRC Record: Novel
Methods for Generating Ultrasound" [01.June96]
May 1996
Introduction
We did a lot of travelling last month and brought back these reports.
UT in Israel is our first one and is an addition to the new
Ultrasonics by Country section. See the Marketplace for summaries of our visits to
MTQ in Birmingham and Tube&Wire in Düsseldorf, both of
which contain intensive market news condensed from about 30 product
showcases.
These are not advertisements, nevertheless, we hope that sponsors will
find this journal useful and interesting.
Be sure to see our article about a UT rotary head for plastic gas
pipes!
Articles
New advantages for quality control of Plastic Gas Pipes with an
Ultrasonic Flaw Detection Rotation Machine.
The article describes the need for in-line automated ultrasonic flaw
detection for gas plastic pipes, describes a possible design
and gives recommendations for buyers as well as suppliers' sites, and
serves as a general
introduction on how to find a specific ultrasonic test procedure. The system is based on Ultrasonic testing with a rotary head
and is available on the market. By R. Diederichs. [5pp+8gifs] [Abstract]
Reducing the influence of human factors on the reliability of manual ultrasonic weld inspection.
Being under influence of human factors the low cost manual ultrasonic testing of welded joints can't compete with the expensive and hazardous
X-ray or isotope inspection in many cases, despite the advantage of having highest sensitivity. A new Manual Ultrasonic Testing Objectivization Methode was created.

UT for determination of the adhesive of multilayer structures
A new method is introduced that makes possible the quantitative

Ultrasonic testing and image processing for in-progress weld inspection
This short artcicle describes some of the problems to be encountred
when using pulse echo methods
for flaw detection in incomplete welds. As an alternative, Time of
Flight Diffraction methods are
proposed and image processing techniques for automatic defect detection
are described.

A simulation program for optimizing of so called coupling shoe, and the
incidence angle for ultrasonic techniques.
The Program features a simulation of ultrasonic testing on a
computer-rendered specimen.
The sound transmission within the specimen is calculated and drawn on the
screen, based on simplified geometric optics. Also an A-Picture of the
echo is simulated and displayed.

Ultrasonic and Radiographic NDT of butt
fusion welds in Polyethylene Pipe
This paper summarises work at TWI on NDT of butt fusion welds in polyethylene and compares this work with results from other published literature on this topic. Pulse-echo compression wave technique, Pulse-echo creeping wave technique, the tandem technique and Time-of-flight-diffraction (TOFD) technique was applied.
