FPI refers to the fluorescence penetrate inspection. Friedrich Forster, the one who had adapted eddy current technology during the war, went on to found the Forster Group, which made advancements in developing ECT technologies. Vol , Issue 1, Corrosion can be detected by eddy current testing and if the metal has thinned. Materials to be tested can be non-ferromagnetic or ferromagnetic.
Definitions and Data Tables for Eddy Current Testing
Diagnostics of the Mechatronic Rotating System p. The reason of this phenomenon is connected with a very important feature of the eddy currents. True depth of penetration depends on sample thickness and probe diameter as well as frequency, permeability, and conductivity. Permeability is, also, not uniform. Deeds, Analytical solutions to eddy-current probe-coil problems. This not weld inspection its meterial inspection. A review on non-destructive evaluation of rails:
