Based on the syllabi issued by the American Society for Non-Destructive Testing (ASNT), ISO/TR25107, and the requirements of PCN, the course provides a thorough foundation for technicians, inspectors, and engineers called upon to witness, supervise or conduct Eddy Current Tests.
The course satisfies the formal training element of the Recommended Practice SNT-TC-1A issued by ASNT, ISO/TR25107 and the requirements of PCN, and hence is the basic foundation which can lead to qualification under PCN, SNT-TC-1A, BS EN 4179 or NAS-410 requirements.
Practical aspects are emphasised by ensuring that theoretical training is complemented with practical sessions concerning techniques and methods under the guidance of qualified instructors. At level 1, practical exercises are limited to the use of Analog display instruments.
Students are introduced to the variety of practical applications associated with Eddy Current Testing, paving the way for further training in Specific Techniques and Industry sectors.
Students are assessed for comprehension and progress during the course, via a structured series of both theoretical and practical phase assessments, which facilitate counselling and assistance where required. On request a formal end of course examination can be conducted.
The content of the course includes:
- The basic theory of Electric Current Flow, Alternating Currents and Resistance.
- Induction (Electromagnetic). Impedance, Frequency, Magnetism, Electro Magnetics,
- Magnetic Properties of a material. Eddy Current Theory. Tests coils and probes.
- Properties affecting Eddy Currents. Eddy Current test equipment.
- Basic test circuits. Detectable Discontinuities and Non-relevant Indications.
(A full Syllabus can be supplied on request).
Lunch, refreshments and a full set of course notes will be provided during the course.
