What is the eddy current inspection method?
Eddy current testing is a non-destructive testing (NDT) inspection method used for a variety of purposes, including for flaw detection, material and coating thickness measurements, material identification and establishing the heat treatment condition of certain materials.
How do I become an eddy current technician?
At a minimum the technician performing eddy current inspection is required to have 40 hours of formal classroom training and 1200 hours of on the job experience before performing eddy current inspections on aircraft and accepting or rejecting parts. Most technicians are tested every three to five years.
What are the three basic functions performed by the eddy current test instrument?
The eddy current test instrument performs three basic functions: generating, receiving, and displaying. The generating portion of the unit provides an alternating current to the test coil. The receiving section processes the signal from the test coil to the required form and amplitude for display.
What are the types of eddy current testing?
Probes—Eddy Current Testing Equipment
- Surface Array Probes.
- Tubing Array Probes.
- Eddy Current Testing Handheld Instrument.

What are the materials used in eddy current inspection?
The saturation probes contain conventional eddy current coils and magnets. This inspection is used on partially ferromagnetic materials such as nickel alloys, duplex alloys, and thin-ferromagnetic materials such as ferritic chromium molybdenum stainless steel.
What is the NDT course?
NDT Course Details NDT stands for Non-Destructive Testing. And NDT is an inspection or testing methods to evaluate properties, characteristics, quality or defects of a material, component or equipment in a system.

Which instrument is used by eddy current?
They are used to detect flaws, determine thickness, inspect welds, measure conductivity, and sort alloys. Eddy current instruments include a straight or angled magnetic probe and an analog or digital meter with a zero reference point.
What are the advantages and disadvantages of eddy current inspection?
What are the advantages and disadvantages of eddy current testing?
- Sensitivity to surface defects.

- Can detect through surface coatings.
- Accurate conductivity measurements.
- Can be automated.
- Little pre-cleaning required.
- Portability.
- The disadvantages of eddy current testing are:
What is the major limitation of eddy current inspection?
A primary disadvantage of ECT is that it only works with a current, meaning it cannot be applied to non-conductive materials. It’s also non-conductive with ferromagnetic materials, as ECT equipment is subject to permeability changes on the welds.
