Edward Korkowski

ASNT ET Level III Cert No. 47920

Ed Korkowski was introduced to NDT in 1987 when he enrolled in the two-year vocational NDT training program at Ridgewater College in Hutchinson, MN. After receiving his diploma in Nondestructive testing, Ed went to work for a nuclear service company where he worked as a certified Eddy Current data acquisition operator and data analyst from 1990-2005. Ed became an EPRI-QDA (Qualified Data Analyst) in 1994, an ASNT Level III in ET in 1995, and a certified NDE Instructor 1998. Between 1998 and 2005, Ed spent most of his time as an Eddy Current data analyst, and providing EPRI QDA training to data analysts in Canada, Europe, and throughout the USA. In 2005, Ed went to work for a major energy company, where he is currently employed as the Principal ET Level III. Ed currently manages the eddy current inspection program for one of the world's largest energy companies.

Social proof: testimonials

“" Awesome Eddy Current knowledge". The "Wikipedia" of all things, Eddy Current. I reached out to Ed on a whim and inquired about possible specific training. After gathering some basic info about myself and my training goals, we scheduled a time. Ed was very accommodating to my training goal. Was able to cover this training over a weekend without having to take many days off from my full time job. I would highly recommend Ed for your training needs....Thanks again Ed!”

“"Ed’s Eddy Current Level II (Surface and Tubing) Course is a fantastic resource for current and prospective ET Level II Technicians. Coming from the Air Force, I was able to expand my knowledge base and hone in on concepts like Phase Lag and sectors of ET I haven’t had experience with like tubing inspections. I would recommend this course to anyone looking for a straight-forward and in-depth course to prepare for certification".”
