Development of Uniform eddy current probe for improvement of defect detection on the metal material

摘要

Currently, Non-destructive testing (NDT) is an essential portion in the fabrication, manufacturing andinspection services to ensure the integrity and reliability of products, to maintain the manufacturing process,reduce production costs and maintain consistent quality. Until now, in material inspection, one method that famousin NDT is electromagnetic methods that known Eddy current testing. This method has advantages in measuringcracks or defects that can be detrimental to critical applications. In common, it used to evaluate non-ferromagneticmaterial both on the near surface or far surface. Besides, this test can also measure the conductivity of the materialused in its application to measure corrosion, metal thickness, and metal hardness.
