About the course

Eddy-current testing (ET) is one of many electromagnetic testing methods used in nondestructive testing (NDT) making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials.
During the classroom training students will learn the requirements to become Qualified & Certified to perform Eddy Current Testing. The course covers aspects of Eddy Current inspection such as basic principles, equipment, test techniques, and more. Classroom and practical application ensure that all students complete the course with the understanding of the basic principles of Eddy Current Testing.
Eddy Current Level I (ET) course allows students who wish to obtain the required 40 hours of classroom training in accordance with SNT-TC-1A and CP-189. The curriculum encompasses the body of knowledge outlined in CP-105 in addition to hands on training.
