So, to clear up any confusion, I have sent this to the list. Inspection Trends is a quarterly publication put out by the American Welding Society(AWS) for inspection and testing personnel. We have a base circulation of approximately 17,000, including individuals who have been certified by AWS as welding inspectors and NDE professionals. The magazine is practical in nature, and features short, non-scholarly articles for use in the field. The magazine contains a question and answer section, a new products section, new literature, editorial, etc. The inaugural issue of the magazine was released in summer 1998.

As you may notice online, we've started the new year off right with improved NDTnet navigation. The main page "www.ndt.net" will stay almost static; from there you can access all departments as well as the each month new current issue page. We are also looking forward to seeing increased sponsor activity in this new Logo section on the top of this page. Most of this month's issue focuses on NDT in aerospace, with papers submitted by PACNDT conference authors and selected independent authors. We also have reports on the PACNDT and DGZfP conferences. The latter one also features commentary on NDT Politics and the Internet. _____________________ This Month's Articles: The Use of Neutron Radiography in the Inspection of Aircraft Composite Flight Control Surfaces.

SCOPE OF WORK 1. Review of relevant plant PFD’s, P&ID’s, piping plan, job books, etc. in order to understand process and equipment involved. 2. Visit the facility in detail and cross check installation with available drawings and to prepare sectionalized isometric line diagrams for use in ultrasonic thickness monitoring. Enough such diagrams will be generated to cover piping/equipment in each facility. These diagrams will indicate process parameters, materials used and test points selected for monitoring the thickness. Criterion for selection and categorization of test points will be based on severity of corrosivity of the medium and criticality of the piping/equipment in question. 3. Coding of test points in sectionalized ISO’s in conformity with the requirements of Ultrapipe software for data off-loading and processing. The code of each point is unique. The coding methodology has already been developed for a similar kind of project using Pipe+ software. The same technique may be used with Ultrapipe software having enhanced capabilities (windows base). 4. Re preparation of ISO’s on computer using AUTOCAD which is interfaced with data management software. For Turk Amine (project’s name), ISO’s and other drawings are available in electronic form. But electronic copy of any drawing related to old Turk is not available. 5. Programming the hand held UT meter and data logger for on site data collection, based on the above mentioned system. 6. On site marking of test points based on already prepared sectionalized ISO’s and preparation of test points for data collection. 7. On site data collection. 8. Offloading data from UT meter cum data logger in Ultrapipe software installed in PC at UTPI’s office. Commissioning of Ultrapipe software by performing data analysis, calculations and preparation of various reports. Formats of such reports from PIPE+ is attached as an example. 9. On job training of UTPI’s inspection crew by involving them into all phases of this work, so that they can continue periodic data collection later. COMMERCIAL · Consultant to submit their schedule of charges for the above works with breakdown of personnel categories which will be involved. Items to be covered are travel, charges per day, hour and work on holidays, etc. Separate estimate charges for travel on site and site accommodation, etc. In case UTP is unable to provide this. · Consultant to submit separate proposals, one for Turk Amine Plant and the other for the Turk Facility.

Ultrasonics on concrete can be made to work but composition of the concrete regarding agregates and reinforcing bars will determine resolution. If you just want to identify anomalies quickly Infrared Thermography may work as it is often used to identify voids or spalling in concrete structures. If the concrete structure is very thick "such as blast prevention" then low frequency radar often termed "Ground Penetrating Radar" may be your best solution. This is commonly used to identify discontinuities in concrete bridge decks or runways. We have done some work on blast protection defences in the past. Let me know more about your problem and we will see where we can assist you.

We have had considerable experience with this application, and it can be done quiet successfully with the proper sort of ultrasonic gage (a precision gage with adjustable setups, NOT a gage designed for corrosion survey, which is what I belive Mr. Gamlin was using). Typically, we use delay line transducers of 10 or 20 MHz for very thin sections (under 3 or 4 mm) and lower frequency contact transducers (5 MHz) for thicker sections. It is also necessary to remember two things: because of the acoustic impendence relationship between wax and ceramic, the echo from the ceramic will be phase reversed, so you need to use a gage that can compensate for this. Also, sound velocity in wax chnages rapidly with temperature, so you need to either keep the wax at a constant temperature or compensate by recalibrating velocity. --Tom Nelligan Senior Applications Engineer, Panametrics, Inc. http://www.panametrics.com -- -------------------==== Posted via NDT NewsWeb ====----------------------- http://www.ndt.net/newsweb/newsweb.htm Topics, Statistics, Search, Post From tover@awsparc.amweld.org Thu Jan 28 16:14:48 1999 From: tover@awsparc.amweld.org (Terri Over) Date: Thu, 28 Jan 1999 11:14:48 -0500 Subject: receiving Message-ID: I am receiving loud and clear.

I'm working on my Phd and i'm imaging materials by moving a sample slowly between transmitter and reciever transducers and measuring the difference in the time of flight between these two transducers to produce an image of how this time changes as i scan the sample so i can then relate what i see to physical properties looked at with other techniques. My Q is has anybody heard of anybody trying use deconvolution to improve ultrasonic images and whats your opinion on how worth while this is going to be ????? any references or links to pages on ultrasonic techniques would also be most welcome Many thanx Matt (Molecular Physics and Instrumentation, University of Leeds, phymjh@phys-irc.leeds.ac.uk) ------- end of forwarded message ------- From jay@dirac.nde.swri.edu Sat Jan 30 16:18:47 1999 From: jay@dirac.nde.swri.edu (Jay Fisher) Date: Sat, 30 Jan 1999 10:18:47 -0600 (CST) Subject: Photothermal radiometry (fwd) Message-ID: <199901301618.KAA07006@dirac.nde.swri.edu> ------- start of forwarded message ------- Path: rQ!rQdQ!remarQ73!remarQ-uK!supernews.com!news-feed.inet.tele.dk!bofh.vszbr.cz!newsfeed.gamma.ru!Gamma.RU!news2.aha.ru!aha!not-for-mail From: "Pavel Leonov" Newsgroups: sci.techniques.testing.nondestructive Subject: Photothermal radiometry Date: 30 Jan 1999 14:38:29 GMT Organization: Mr. Postman Lines: 14 Sender: lnov@aha.ru@p143-n67.dip.aha.ru Message-ID: <01be4c5e$5222c600$LocalHost@chief> NNTP-Posting-Host: p143-n67.dip.aha.ru X-Newsreader: Microsoft Internet News 4.70.1157 Xref: rQ sci.techniques.testing.nondestructive:3943 Dear colleagues, NDT methods based on the analysis of a caloradiance of materials heated by source of pulse or periodic irradiation, including laser source (laser photothermal or thermal wave radiometry) are known more than decade.

Additional profits can be obtained: if transducer PSF,point-spread function, is non-symmetric, it can be compensated. Quite complicated is to obtain suitable PSF, therefore it sometimes is aproximated by some mathematical function. In case of highly attenuating material deconvolution using the PSF in the conventional way can fail, if deconvolution is for different depth reflectors.Special methods have to be employed.

This is the detection and characterization of dislocations in silicon wafers after ion implantation. Thermal wave is used to verify that annealing has removed the dislocations prior to subsequent processing. More information can be obtained from: Therma-Wave 1250-T Reliance Way Fremont, CA 94539 (925) 490-3663 For information on the capabilities of this method you should look at the following people who have published in this area: Jon Opsal John F. Murphy F. Alan McDonald George Wooten Of course many others as well have contributed these are just the ones in my notes. Thermal wave is also sometimes called photoacoustics. Excitation from the infrared to the low energy x-ray have been used for different purposes. Regards, Robert (Rocky) A.
