The Chicago Section of ASNT met virtually on Monday, April 12, 2021 with eighteen guests and members in attendance on-line. The guest speaker for the evening was Emilie Peloquin, Director of Global Advanced Product Support for Olympus Corporation.
Emilie’s presentation was entitled, “Advantages and Limitations of Using Total Focus Method (TFM).” The discussion highlighted the differences between Full Matrix capture (FMC) and the TFM technique. The use of the proper wave sets was stressed and a number of slides demonstrated the need to understand the type of flaw that is trying to be detected to obtain adequate results. To improve the inspection method, modeling was used to illustrate the types of flaws that could be detected in certain areas of a weld zone. With the wrong selection of wave sets, the flaw was totally missed. The ability to visualize the flaws and wave propagation with the modeling greatly enhanced the detectability and accuracy of the inspection. Many attendees indicated that this was one of the best explanations of the method that they had ever heard.
Chuck Johnson of Karden Sales, the ASNT Chicago Section chairman expressed appreciation to the speaker and to the audience for their attendance and valuable questions at the conclusion of the presentation.

The Chicago Sections of ASNT and AWS met jointly using a virtual program on Monday, February 8, 2021,
with 22 guests and members in attendance.
The guest speaker for the evening was Stuart Kleven of Alloyweld Inspection Company, Bensenville, Illinois.
Stuart’s presentation was entitled, “Additive Manufacture and NDT of Aerospace Components”. The talk was centered on the new ASTM Guide E3166 developed by ASTM Committees E07, E08, and F42 and AWS Specification D20.1 for additive manufacture and inspection. Additive manufacturing is rapidly growing in popularity as a manufacturing process for complicated parts. The tremendous cost savings as well as improved mechanical properties is the driving force in the advancement of these manufacturing methods. With the advancements, the part designers are also pushing the limits with respect to defect sizes permitted. With the new processes there are different types of discontinuities that must be detected and evaluated. This has caused companies to investigate new methods for detection, such as computed tomography, thermography, eddy current and process compensated resonance testing. The surface condition of as-built parts also affects the inspection results. The surfaces are not as smooth as traditional parts in some cases and can mask discontinuities. The new ASTM document provides tables and charts that highlight which methods could be employed to find specific types of discontinuities.
A case study of a critical aerospace component was also highlighted during the talk, employing computed digital x-ray inspection (CR), computed tomography (CT), pre-penetrant etching, penetrant inspection and final chemical conversion coating.
December 14, 2020
The Chicago Section of ASNT met virtually on Monday, December 14, 2020.
The guest speaker for the evening was Mr. Larry Bartoszek of Bartoszek Engineering.
Larry previously worked at Fermi Laboratory for quite a number of years. His presentation was entitled, "The Connection Between the Periodic Table and Astronomy." This talk described the intimate relationship between astronomy and the Periodic Table by looking at how everything we learn about the distant universe comes from dissecting starlight and starlight comes from excited atoms changing their energy states. He started with a brief history of the universe to see where atoms come from and the forces that hold them together. Larry then discussed how the electron shell structure of the atom allows them to give off light and organizes them into the Periodic Table. He examined how the light from distant atoms in stars and galaxies changes as the galaxies move away from us. After that he showed how spectroscopy on starlight leads to the expansion of the universe and the acceleration of the expansion now thought to be caused by dark energy. All of this comes from an understanding of the unique “fingerprints” of atoms in the light they give off. Larry also showed the work that he did on the Sloan Digital Sky Survey Telescope

The Chicago and Rockford Stateline Sections and active members of Region 12 met virtually on Monday, January 11, 2021. The guest speaker for the evening was Mr. John Iman, President of ASNT. He has been involved with nondestructive testing in many areas over the span of his career.
John described how involvement in ASNT has positively affected his career and personal life, to the point of even working with astronauts, which he never could have predicted. His presentation was entitled, "The State of the Society.” John highlighted four areas of which the society will be concentrating; Programs, People, Strategic Planning and Problems. Under Programs, he reviewed the progress made with the ACCP, ISQ and other initiatives with ISO and other societies. Under the topic of People, he addressed the importance of growing the number of members and the methods being used to retain and gain new members. With strategic Planning, the emphasis was placed on strengthening the certification program, improving advocacy of nondestructive testing to Federal & local government bodies and integrating with other societies, showing the value of membership to practitioners and their career advancement as well as addressing new technologies. In confronting challenges that ASNT faces, John issued a call for action. The foundation of ASNT has been the great volunteer sprit in its members; even with that, the on-going need to fill committee positions with new people was stressed. Finally, a request was made to the meeting attendees to express their needs or concerns. A number of persons in attendance gave valuable input on areas where improvement or involvement of ASNT could benefit them and the society.
Chicago section chairman, Chuck Johnson of Karden Sales closed the meeting with a word of appreciation for the presentation and member involvement.
March 8, 2021
The Chicago Section of ASNT met virtually on Monday, March 8, 2021 with thirty guests and members from Region 12 in attendance on-line. The speakers for the evening were Dave Ronzani, James Dinell and Steve McCullough of Alltranstek. The title of their presentation was,
“The Qualification and Maintenance of Railroad Tank Cars Using NDT”.
Dave Ronzani chronicled the history of the development and changes in tank cars from 1863 through the present and explained how they are manufactured and highlighted the NDT methods used to inspect tank cars. Next, James Dinell addressed the regulatory requirements that apply and explained the Federal Railroad Administration (FRA) and American Association of Railroads (AAR) involvement in the application of the rules for qualification and risk based assessment of cars. He also reviewed the development of NDT personnel qualification and certification under the AAR rules. Finally, Steve McCullough described the inspections in detail and how various NDT processes such as
VT, MT, PT, RT, UT, LT and IRT are applied.
Chuck Johnson of Karden Sales, the ASNT Chicago Section Chairman expressed appreciation to the speakers and to the audience for their attendance and valuable questions at the conclusion of the presentation.
