Eddy Current - Level I

When a magnetic field cuts through metal, a current is induced. If a magnetic field cuts a wire in a closed circuit, a current is induced around the circuit. However, if a magnetic field cuts through a sample of metal that is not connected to a circuit, an ‘Eddy Current’ is produced. This Eddy Current is localized in the metal and has a flow pattern. The flow pattern is disrupted by discontinuities from the surface to a shallow depth of penetration. The method is quick and very sensitive. No contact with the metal is required. All metals may be subject to this form of testing.

Below is an example of a syllabus that is used for Eddy Current training courses. GTS is able to cater the syllabus to satisfy the requirements of a specific written practice if necessary.

General Theory:

Introduction to Non-destructive Testing

This course is designed to introduce students to the five major Non-Destructive Testing disciplines:

  • Radiographic Testing (RT)
  • Ultrasonic Testing (UT)
  • Visual Testing (VT)
  • Penetrant Testing (PT)
  • Magnetic Particle Testing (MT)

This course discusses the benefits and limitations of each method as well as an overview of the various discontinuities that may be encountered. Six other methods are also briefly discussed.

Duration: 4 days (40 hours)

Magnetic Flux Leakage

API 653 and ASNT define the requirements for Magnetic Flux Leakage testing (MFL testing).

This course provides valuable information on the advantages and limitations of MFL testing, and the equipment used to perform the tests.

Although the focus of this course is for the exam of above-ground storage tank bottoms, the theory is general to all MFL testing.

The class is 24 hours and designed for those who have already completed Magnetic Particle testing. The basis of the method is to reach near saturation of ferromagnetic material and use eddy current sensing devices to detect the flux leakage created at material changes.

Duration: 3 days (24 hours)

Magnetic Particle Testing - Levels I / II

Magnetic Particle Testing (MT) is done by inducing a magnetic field in a ferro-magnetic material and dusting the surface with iron particles (either dry or suspended in a liquid). Surface imperfections will allow the magnetic field to leak out of the part, distort the magnetic field and concentrate the iron particles near the imperfection, thus indicating their presence.

Magnetic Particle Testing (or Magnaflux as it is sometimes called) uses magnetic leakage fields to detect surface and near surface cracks and discontinuities.

Identified Learning Outcomes:

  • Identify material properties
  • Operate magnetic field generating equipment
  • Application of the correct inspection technique
  • Interpret Indications
  • Review national and international codes, standards and specifications

Measurement of Learning Outcomes:
Candidates will have dedicated instruction by tutorial and physical “hands on” visual aid equipment.

  • Pre- and post- basic skills assessments
  • Daily skill assessments
  • Laboratory applications daily assessment
  • End-of-course assessment

Student Success:
Student success is a measurable quantity. The pre- and post-course skills assessment, practical lab work and in-course daily skills assessment results are retained as a documented record. Additionally, an end-of-course examination covering the course topics shall be completed.

Perquisites & Comments:
This course is generally combined with Penetrant Testing I / II. Presentation of the course on-site is quoted separately.
