NDT Methods: Eddy Current
Testing is the process of inducing small electrical currents into
an electrically conductive article and observing the resultant
reaction between the magnetic fields involved. A number of factors
within the article will affect the flow of these eddy currents and
means exist for relating test indications to these factors.
Eddy Current testing can be applied to cylinders, tubing, sheet and coating and provides a means for measuring conductivity, detecting discontinuities and determining the thickness of coatings or plating on articles. Since a continuous indication is a part of the basic testing system, automatic production testing is particularly feasible.
As can be discerned from the description of the various tests described, each is a filed unto itself and involves all the parameters of education, equipment and research that any technical field requires.
The afore-mentioned methods described are the main tools we employ in serving virtually all the major industries within Canada.
We specialize in utilizing our capabilities for problem solving analysis of structural materials to evaluate condition and reliability.
