Eddy current surface probes
WebEddy 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, … WebThe measured defect signal value using the probes is in the range of (20–200) millivolts. Both probes can detect subsurface defects on stainless-steel samples with average surface roughness of 11.6 m and titanium samples with average surface roughness of 8.7 m.

WebNov 1, 2016 · Flaw Detection. It’s usually carried out with pencil probes or ‘pancake’ type probes on ferrous or non-ferrous metals. Frequencies from 100 kHz to a few MHz are commonly used. Depending on surface … WebThe titanium allows eddy currents to penetrate to the aluminum layer if the gain available is sufficient. Unfortunately, when the aluminum is covering the titanium, the eddy currents do not penetrate this as the conductivity is …
WebJul 5, 2024 · The eddy current density, and thus the strength of the response from a flaw, is greatest on the surface of the metal being tested and declines with depth. It is mathematically convenient to define the “standard depth of penetration” where the eddy current is 1/e (37%) of its surface value. X L. Probe in. Ferrite. Crack in Steel. Steel WebDuring the testing of conductive material, an eddy current probe detects changes in the electrical conductivity or the induced magnetic field. This is an indication of a flaw in the metal surface. Eddy current probes are sensitive to these changes and can easily identify and transmit this data to the operator. Advanced eddy current probes and ...
