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 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. He manages the inspection program at multiple nuclear sites. 

 ASNT Level III certificates held during the production of online NDT courses taught by him include Eddy Current Testing.

Course Description 

ECT is one of several electromagnetic testing methods used in NDT and based on electromagnetism. It is often the method of choice for surface and tubing inspections.

This course addresses required and recommended training topics for Level I Eddy Current technicians. It is intended as an initial training course for individuals pursuing Eddy Current certification and can also be used as a refresher for those candidates for recertification. It is ideal for anyone interested in understanding the basic principles and applications of Eddy Current Testing.

This course is based on the body of knowledge as defined in ANSI/ASNT CP-105 and meets the recommendations for training as described in SNT-TC-1A.

Completion of this training course and the associated quizzes and examinations can assist employers in their qualification and certification of ECT personnel.

This training course is divided into the following 18 modules: 

1. Introduction to Electromagnetic Testing 
2. Magnetism 
3. Electric Current Theory 
4. Electromagnetic Induction Theory 
5. Eddy Current Properties 
6. Material Properties 
7. Types of Instruments and Displays 
8. Types of ECT Inspection Coils
