Eddy Current Testing (ET)
Eddy Current Testing Levels 1 and 2 Course (Combined)
Course Duration: 10-Days (80 hours)
0830hrs to 1730hrs Daily
This course satisfies the formal training element of the American Society for Non-Destructive Testing SNT-TC-1A, ANSI/ASNT CP-105 and NAS 410 / EN 4179 and is suitable for engineers and technicians at all levels of experience that require formal training for qualification in this subject.
The training programme consists of both theoretical and practical hands-on application, allowing the student time to obtain a good foundation in this method of NDT by practicing a variety of inspection techniques under the supervision of qualified instructor(s) using different methods and techniques of eddy current testing. Students will also have the opportunity to inspect actual aircraft components and structures.
Standards and specifications associated with Eddy Current Testing in the Aerospace Sector will be introduced and discussed in this course.
The aim of this course is to provide students with an adequate theoretical and practical knowledge of the Eddy Current Testing method including calibration checks, scanning techniques, interpretation/evaluation techniques, and writing of NDT instructions/test reports to prepare them for qualification examinations in accordance with their employer’s NDT Written Practice.
The course comprises of:
- Introduction to Electromagnetic Testing
- Eddy Current Theory
- Eddy Current Instrumentation
- Readout Mechanisms
- Eddy Current Sensing Elements
- Flux Leakage Theory
- Flux Leakage Sensing Element
- Coil Impedance
- Eddy Current Test Systems and Analysis
- Selection of Test Frequency
- Electromagnetic Testing Applications
- Factors Affecting Flux Leakage Fields
- Selection of Magnetization Method
- Flux Leakage Applications
- Remote Field Testing
- Alternating Current Field Measurement
- Electromagnetic Testing Standards and Procedures
A comprehensive topical outline will be provided to the students during the course.
All students will be continuously assessed during the course by progress tests and homework, together with a theoretical and practical End-of-Course examination, as applicable.
