International School of Aerospace NDT Limited
Eddy Current Inspection of Aerospace Structures and Components
(80 hour/10 day Course)
This Level I/II course satisfies the syllabus requirements of ASNT-CP-189, SNT-TC-1A, NAS 410, BS EN 4179, PCN and ISO 9712. It is suitable for engineering inspectors at all levels of experience who require formal training and a qualification in this subject.
The training programme covers 50% theory and 50% practical application allowing the student time to obtain a good foundation in this method of NDT by practicing a large variety of inspection techniques under the supervision of qualified instructors using the latest inspection equipment.
The course comprises:
- Basic principles of electricity.
- Generation of eddy currents.
- Electromagnetic induction.
- Variables that have an effect on eddy currents.
- Different types of test equipment.
- High and low frequency.
- Types of calibration blocks.
- Various types of probes, coils and coil arrangements.
- Practical applications of eddy currents.
- AC theory involving applications of Ohm's Law to simple and complex circuits.
- Study of basic eddy current test circuits.
- Vector diagrams.
- Theory of impedance plane analysis.
- Practical applications of phase analysis.
- Interpretation of relevant and non relevant indications.
- Preparation of inspection techniques and report writing procedures with emphasis on appropriate specification interpretation.
All students are continuously assessed during the course by homework and progress tests together with a theoretical and practical end of course examination.
At the end of the course the students can also take approval examinations in Eddy Current Inspection at Level I, II or Level III to SNT-TC-1A, NAS 410 or BS EN 4179 in accordance with their company written practice.
International School of Aerospace NDT also acts as an outside agency providing Level III services as defined in the aforementioned documents.
