Our Speaker will be Mr. David Mitchell, his career in NDT began in 1974 when he became a Penetrant and Magnetic Particle Level 2 at Mitchell Laboratories and a member of ASNT. By 1977 he was named the Quality Manager of Mitchell Labs and had become certified in UT and RT. In 1980 David received his ASNT Level 3’s in UT, PT, & MT. From 1980 to 1992 David taught a variety of classes at Don Bosco Technical Institute for the GLAS section of ASNT. In 1987 David became active in the leadership of the GLAS section, and in 1992 he served as Chairman.
In 1990 David was appointed Vice President and General Manager of Mitchell Labs, eventually to become President in 2002. In 2004 he became President of the newly formed Mitchell Metrology.
During his career, David guided Mitchell Laboratories into a leader among independent labs in automated ultrasonic inspection. He added multi-axis contour following gantry systems for the inspection of large 787, F-22, C-17, and F-35 contoured composite panels, and deployed several different contour following systems for the high-speed inspection of composites and metal components.
David Mitchell led the effort to implement phased and linear array inspection systems for high volume and critical ultrasonic 787 aircraft examinations, developed phase array inspection of critical titanium welds for expendable launch hardware, and supported materials and processes development for monolithic alpha-two and gamma titanium aluminides for reusable launch systems.
In December of 2009 David separated from Mitchell Labs. In of March of 2010 David formed Mitchell NDT Associates. In 2011 David formed Composite Inspection Solutions located in Bensalem, PA as part of XRI. CIS is now part of Arcadia Aerospace.
David Mitchell is currently an ASNT Certified Level 3 in UT & PT. Certification #9007. David is also a NAS410 Level 3 in UT, MT & PT.
Life time member of American Society for Nondestructive Testing (ASNT); ASNT Fellow, Class of 2002; ASNT Mentoring Award Winner, 2010; Nadcap Supplier Voting member; Member of ASNT Board of Directors 2010 to 2013 and 2019 to present.
Topic Title: “Advances in UT using linear arrays ”.
Abstract: The presentation will be on advancements being made in the field of UT, using linear arrays to increase inspection speeds and reliability. The discussion will center on the ability of PAUT systems to renormalize the UT beam to the entry surface without the use of mechanical means at normal scan speeds.
