The Chicago Section met 9 March at Crazy Pour in Villa Park, Illinois, with 20 members and guests in attendance. Stephen Berg of Berg Engineering & Sales presented on portable hardness testers, covering the advantages and benefits of the technology.
Berg related how hardness measurements are essential for the manufacturing of different types of products and explained the use of hardness control in various fields. He first gave a review of the difference between stationary units and portable instruments and their governing specifications. The importance of surface preparation and the effect it can have on accuracy was stressed. It was emphasized that portable hardness testers are used as an adjunct and not a replacement for traditional, stationary hardness testers. Limitations due to weight and size were noted as well. It was explained how portable hardness testers utilize indirect techniques, implementing ultrasonic contact impedance and rebound techniques.
Because of their size and weight, the portable units are appropriate for use in the field and for hard-to-reach places. Numerous types of units were described along with the differences in the way the readings are obtained and standardization requirements. Berg also brought examples of different units.

Rockford Stateline Section Chair Joel A. Mohnacky organized and hosted a virtual meeting between four ASNT sections on 19 May. The sections participating were Rockford Stateline, Greater Houston, Pittsburgh, and Chicago.
After Mohnacky opened the meeting, he introduced Regional Director, Region 12, Charles (Chuck) P. Johnson. The speaker and presenter for the evening was Applications Engineer Dana Begun, Ph.D., of Waygate Technologies. The topic of the presentation was “CT Imaging for Metrology.” Begun spoke for 60 minutes on the advancement of 3D printing and additive technologies, which has led to a growing demand for new measurement strategies. To meet these new challenges in the manufacturing industry, industrial CT has become a critical tool for inspections requiring metrological rigor. She explored and presented the basics of metrology by CT and discussed several major factors that influence metrological performance.
Seventy-two attendees logged on to the virtual meeting. Attendees included representatives from Houston, Chicago, Pittsburgh, Ohio, Minnesota, Canada, and as far away as Singapore. This collaboration proved to be a huge success. The Section received positive feedback and hopes to provide more virtual technical presentations and meetings in the future.
The India Section successfully conducted its training program titled “Basic PAUT: Part 1” via videoconferencing on 23 May. There were about 280 members and guests in attendance. The speaker was Siddarth Kasi Viswanath. The session was interactive, and members enjoyed the online meeting.
The India Section hosted a virtual technical meeting on phased array ultrasonic testing on 23 May.
The Iowa Section held a virtual meeting on 30 April with six members and guests in attendance. Jin Yan, who is currently a Ph.D. candidate in the department of civil engineering at Iowa State University, presented on “Model-Assisted Structural Health Monitoring.” The presentation highlighted a theoretical framework for designing a structural health monitoring (SHM) system through smart sensor and material technology, adaptive system integration, and big data analytics. Yan’s research focuses on advancing real-time SHM and model-based fault diagnosis and prognosis through the application of smart materials and structures, as well as advanced schemes for nonstationary dynamics simulations.
Northern New England
Newington, New Hampshire
The Northern New England Section held a virtual meeting on 7 May with six members and guests in attendance. The guest speaker was Senior Engineer Thomas (Tom) Kinnare of East Coast Metrology (ECM) in Topsfield, Massachusetts. The focus of the presentation was the use of metrology (the science of precision measurement) as a tool for NDT. A commercial digital scanner was presented along with a discussion on operational theory, followed by a short video and a demonstration of the assembly and operation of the system from its carrying case to scanning the entire calibration lab at the ECM facility.
Due to the COVID-19 pandemic, the meeting presentation was uploaded to the Section’s website for download. The speaker was Michael Virgilio of Mayes Testing Engineers Inc. The presentation included a slideshow titled “UT Weld Root Indications.” Virgilio is an ASNT NDT Level III in UT, MT, and PT, with many years of experience in the ultrasonic testing of welds. According to website statistics, the web page with the download link was visited 116 times during April and the presentation was accessed 74 times.
The Rockford Stateline Section hosted a joint virtual meeting with the Greater Houston, Pittsburgh, and Chicago sections. There were also attendees from Ohio, Minnesota, Singapore, and Canada. The joint meeting was held on 19 May with 72 guests and members in attendance. The guest speaker for the evening was Dana Begun, Ph.D., of Waygate Technologies. After introductions from Regional Director, Region 12, Charles (Chuck) P. Johnson, Begun gave a 60-minute technical presentation of the use of computed tomography (CT) for metrology, including the artifacts needed for maintaining system integrity as well as the best use of CT metrology data for additive manufacturing.
