Eddy current testing is an efficient and precise non destructive test method. This type of inspection is particularly helpful to evaluate heat exchangers and aircraft parts and components.
The flow of periodic electrical currents in conductors, or probes, creates varying electromagnetic fields. These probes are placed near the surface of the test material and can detect the effects of processing and shaping operations during production, as well as corrosion damage or cracking for most nonmagnetic metals and alloys.
Eddy current testing is a valuable tool for the non destructive testing and condition monitoring of a large variety of metallic structures, including heat exchanger tubes, aircraft fuselage, and aircraft structural components.
Eddy Current Testing (ECT)
SERVICE OVERVIEW
PRICING
BENIFITS
- Provides a faster scanning speed than conventional ultrasonic testing (UT)
- Unlike UT, requires no fluid couplant
- The surfaces need minimal preparation
- Eddy current testing can be used through several millimeters of coating
- Can detect very small cracks in or near the surface of the material
- Physically complex geometries can be investigated
- Provide immediate feedback
- The probe does not necessarily have to be in contact with the test object
POPULAR QUESTIONS
-
What is Non Destructive Testing?
Non Destructive Testing is defined as a method used to investigate the integrity of an object, material or system, without impairing its future usefulness.
-
Why is NDT used ?
It is used to determine the following: a) In place quality of Concrete b) Health of Concrete] c) Influence of Time d) Non-availability of old drawings related to the structure.
-
What is the Accuracy?
The accuracy of the diameter measured increase with decrease in cover. It also depends upon the diameter of the bar. For example if the cover is 30 mm and bar diameter is 25 mm the accuracy is + 1 mm. This accuracy can improve if either of these parameters i.e. diameter or cover is reduced
