Research on Detection Mechanism of Weld Defects of Carbon Steel Plate Based on Orthogonal Axial Eddy Current Probe

The 0. 2 mm width and 1 mm depth of weld defects of carbon steel plates were effectively detected in a systematic experiment on the weld of carbon steel specimens. The new orthogonal axial eddy current probe had effectively reduced the unevenness effect of the weld surface on the lift-off phenomenon during the detection process, according to the experimental results.

Microstructural and Wear Properties of Annealed Medium Carbon Steel Plate (EN8) Cladded with Martensitic Stainless Steel (AISI410)

The top layer of martensitic stainless steel was deposited with three layers of martensitic stainless steel deposited using metal inert gas welding on medium carbon steel, resulting in a 51. 5 HRC of the top layer. The uncladded EN 8 plate failed at 478 s due to the presence of high vibration of the pin on disc tribometer that eventually stopped the tribometer. The average grain size of top and middle layer was in the range of 2 to 5. 02 u00b5 million mean grain size, resulting in higher hardness of clad layers than base metal, with increased wear resistance of the cladded EN 8 samples relative to uncladded EN 8 samples.

Extraction of Flux Leakage and Eddy Current Signals Induced by Submillimeter Backside Slits on Carbon Steel Plate Using a Low-Field AMR Differential Magnetic Probe

The MFL method is particularly effective at deep defect detection, but the ECT technique excels at delivering detailed information about defects. MFL and EC signals can be distinguished by utilizing the phase-sensitive detection system, which results in the adoption of a flexible referencing scheme as opposed to static phase referencing. The proposed magnetic probe incorporates highly sensitive anisotropic magneto-resistive sensors that can detect MFL and EC signals caused by artificial slits of various depths engraved onto a 2-mm carbon steel plate. For the optimized frequency band of 110-210 Hz with the corresponding Lissajous curve for the detection of sub-meter back-side slits, there is a good agreement. MFL and EC signals can be successfully captured by an appropriate magnetic probe, resulting in the improved detection of back-side defects in ferromagnetic materials, according to the report.
