WHAT IS ELECTROMAGNETIC TESTING? 

The electromagnetic testing method employs electricity and magnetism in the detection and evaluation of faults, fractures, corrosion or other material conditions. The approach here is that both magnetic fields and electric currents, or just one of either, are induced into a conductive specimen, while the resulting electromagnetic field is detected, recorded and evaluated. Some electromagnetic (EM) techniques are Eddy Current testing (ECT), Alternating Current Field Measurement (ACFM) and Remote Field Testing (RFT). They all have different physics as governed by their unique partial differential equations (PDEs).

WHY SHOULD I CONSIDER A CAREER IN ELECTROMAGNETIC TESTING?

Electromagnetic Testing (ET) is highly effective in the detection of cracks present on or below the surface of metallic objects. ET equipment has become extremely portable and is relatively inexpensive. It is the second most common method specified for NDT. ET has a wide range of applications for surface and tubing inspections used in aerospace, heat exchanger pit detections, weld inspections and many other industrial applications and can detect tight cracks as narrow as 0.003 in.   It is a very important technique because it permits the detection of very small cracks, complex geometries can be inspected with relative ease, it provides immediate results, and it is portable.   Working knowledge of this method and its techniques will open your possibilities to work in many industries. 

ELECTROMAGNETIC TESTING - LEVEL I (ET1)

The ET1 course will provide you with the basic theory and practical knowledge about electromagnetic inspection.  You will learn basic knowledge of Eddy Current testing and you will be able to perform procedures developed for this technique.

WHY SHOULD I STUDY ET1? 

This course is designed for people interested in making a career in Electromagnetic Testing and Inspection.   It is intended for operators, inspectors and technicians responsible for practical application of testing, inspection and writing techniques and instructions for detection of flaws in various types of material across all industry sectors.  

 

ET1 is your first course in your career path.   You will be able to set up the equipment, perform the tests, record them and classify the results.   You should start to report the results.   

Level 1 are technicians qualified to perform calibrations and tests with supervision and direction by higher level personnel. 

 

ET Positions even at entry-level generally require specialized training.   Also the career growth in the future looks bright for ET professionals since the NDT industry will continue to grow substantially.  Also ET professionals can choose to spend the entirety of their career in this industry and maybe expand to other techniques as well.   There’s unlimited room for advancement.
