The speaker for the joint meeting of ASNT and AWS Chicago Sections on October 11, 2017 was Stuart Kleven, Quality Engineer and Responsible Level 3 at Alloyweld Inspection Company, Bensenville, Illinois.  Twenty eight members and guests were present at the Bohemian Crystal Restaurant in Westmont, Illinois.

 Stu’s talk was entitled, “Fabrication and Inspection of Caustic Pumping Skids.”  Alloyweld fabricated all the 316 stainless steel piping on two pumping skids.  The work was performed to ASME B31.3, Normal Fluid Service and an extensive customer project specification.  The customer supplied the piping components, skids, pumps, valves and pulsation dampeners. Alloyweld developed and qualified the weld procedures, qualified the welders, built the piping sub-assemblies, tested and then assembled the systems.  A final operational test was performed along with hydrostatic testing.  The piping sub-assemblies underwent, computed digital x-ray inspection of all the welds, positive metal identification of all components and welds using x-ray fluorescence, visual inspection, borescopic inspection of the weld roots, liquid penetrant inspection of the welds and a baseline ultrasonic wall thickness check of all piping components.

A detailed mapping and documentation package was also included.

The speaker for the joint meeting between ASNT Chicago Section and ASM International-Chicago Regional Chapter February 12, 2018 was Dr. Frederick Schmidt, President of ASM International. Thirty-five members, and guests were present at the Crazy Pour Restaurant in Villa Park, Illinois to hear the talk entitled,

“Use of Nondestructive Testing In Failure Analysis.” 

Dr. Schmidt highlighted that many times nondestructive testing is used to help to make proper decisions during the investigation and analysis of failures.  The test results can assist the forensic investigator as to where destructive test samples should be extracted.   The initial investigation may be involved for planning the inspections and selecting the right method, properly performing the inspections and finally interpreting and evaluating the results. A case study was presented that showed radiographic and magnetic particle inspection results on heavy castings.  This allowed for targeting the areas that were under high stress and facilitated selection of locations where both macro-sections and micro-samples were made. 

Dr. Schmidt then demonstrated how the forensic investigator can organize and present the information using ASTM related documents in a manner such that other investigators, litigators and juries can adequately comprehend the information.  He also highlighted the steps necessary to maintain evidence since many cases can extend several years. here.

The Chicago Section of ASNT met on Monday, May 14, 2018 with eighteen guests and members in attendance at the Crazy Pour Restaurant in Villa Park, Illinois.  The meeting was generously sponsored by Finkl Steel, Chicago, IL; represented by Steve Nelson and Sam Korel.
The guest speaker for the evening was Dr. John Aldrin of the Computational Tools, Gurnee, Illinois.  John discussed how algorithms are developed and indicated that a large amount of data is needed for training and validation to achieve better accuracy.  He highlighted the process which included data acquisition, raw data signal processing, feature classification and finally an accurate call out of the defect type, orientation and size.  

Dr. Aldrin presented some case studies on aircraft that involved massive data collection to develop layers of neural networks with well characterized data and validation through a (POD) probability of detection study.  John then weighed the pros and cons of the use of artificial intelligence. The best use of the artificial intelligence and algorithms is when there are massive amounts of data and the task is repetitive and tedious in nature.  

At this point, John summarized his presentation and revealed that intelligence augmentation is the best practice.  In other words, the analyzed data still needs human review and input to improve the decision-making process and overall reliability.

​April 9, 2018 ASNT Chicago Section held its Educational Meeting, featuring Sharon McKnight, retired from Caterpillar.  There were 20 members and guests in attendance.  Sharon reflected on her 30-plus years in NDT and shared “A Retiree’s Top 10 Wish List for NDT.”













Sharon joined Caterpillar's Lafayette, Indiana, large engine facility in 1984 after completing the 2-year NDT program at Hutchinson Vocational School in Hutchinson, Minnesota (now Ridgewater College).  In 1988 she obtained ASNT Level III certification in 4 disciplines: UT, MT, PT & ET. And in 1996, added a Bachelor’s Degree in Business Administration.  Sharon served as chairperson of the (now inactive) Mid-Indiana ASNT Section from 1987 through 1990.  

Among some of the interesting and pertinent items, Sharon’s wish list included:
 
- Bridging the disconnect between NDT research and the shop floor needs 
- Advancing the science of magnetic particle inspection and assigning equipment 'ownership' to promote better care and accountability of the equipment condition
-  Development of an NDT Bachelors of Science Degree, ideally by partnering programs at already existing colleges and universities
- Employers rewarding technicians with visits to customer sites
-  Increased employer promotion of workforce involvement in ASNT and its leadership roles
- Somehow make magnetism visible!

The meeting was graciously sponsored by Circle Systems,

manufacturers of fine Magnetic Particle products and supporters of ASNT.

November 13, 2017


The speaker for the ASNT Chicago Section meeting on November 13, 2017 was Keith Miller, Materials Engineering, Project Associate at Sargent and Lundy, LLC, Chicago, Illinois. 

Thirty-five members and guests were present at the Crazy Pour Restaurant in Villa Park, Illinois to hear the talk entitled, “How to Make Sense of Data That Does Not Make Sense.”  Keith highlighted that many times nondestructive testing produces test data that has to be interpreted and evaluated to make proper decisions.  There are a number of problems that can occur however, when making these decisions.  For instance, the discontinuity type and its detection may exceed the capabilities of the process or technology used.  Screening processes may be used and may miss critical defects. Time constraints and economic pressures may cause someone to react too quickly before they can evaluate all the data or force them to make wrong interpretations. 

 Three basic areas were highlighted to illustrate how to ensure that proper evaluations are performed and correct results are achieved.  They involved for planning the inspections and selecting the right method, proper inspection protocol and finally interpreting and evaluating the results. If previous results were obtained, they should also be considered.   Keith then reviewed six case studies that demonstrated the problems that can be encountered and errors that can occur if careful planning and analysis is not incorporated in the process. His final a comment was, “Question results that do not make sense”.

The Chicago Section of ASNT met on Monday, September 11, 2017 with seventeen members in attendance at the Crazy Pour Restaurant in Villa Park, Illinois. 

The speaker for the evening was Dr, Christopher Woods, Director of the Oriental Institute Museum at the University of Chicago.  He obtained his doctorate from Harvard University in 2001 and has been studying ancient languages since then.  The title of his talk was, "New Light on a Proto-Literate Accounting Device: The Study of the Clay Envelopes from ancient Mesopotamia".  Dr. Woods spoke on the use of computed tomography for investigating ancient clay envelopes from Mesopotamia around the second to third millennium BC.  The clay envelopes were used as ancient receipts when commodities were traded or sold.  Some envelopes had been broken open in ancient times, but some were still intact.  Sealed inside the envelopes are tokens that represent the commodities sold.  On the tokens are markings that are thought to represent specific items, such as cattle or grain. When the envelopes ceased to be used, clay tablets took their place and cuneiform writing began.  The CT scans were used to view the tokens inside the sealed clay so that they would not have to be broken open.  Some tokens contain symbols that continued to be used on clay tablets.  Archaeologists believe that this may have been the beginning of writing. 

 New NDT methods have impacted artifact analyses and the subsequent understanding of written communication, religion, mathematics and commerce.  Alloyweld Inspection and Northstar Imaging introduced CT technology to the Oriental Institute Museum and assisted Dr. Woods in obtaining the scans on fourteen clay envelopes.
