The top layer of martensitic stainless steel was deposited with three layers of martensitic stainless steel achieving a 51. 5 2. 35 HRC. The failure of the uncladded EN 8 sample was traced to its failure at 478 s. The uncladded EN 8 plate suffered severe damage and high wear, contributing to its loss at 478 s. The average grain size of top and middle layer was in the range of 2–3. 5 mm, with increased hardness of clad layers than base metal, as well as improved wear resistance of the cladded EN 8 samples as compared to uncladded EN 8 samples.

Therefore, the defect of carbon steel plate welds in eddy current testing has always been a difficult problem. Further, a customized orthogonal axial probe was used to conduct a systematic experiment on carbon steel specimens, and the 0. 2 mm width and 1 mm depth of weld defects of carbon steel plates were efficiently established. The experimental results showed that the new orthogonal axial eddy current probe effectively reduced the unevenness of the weld surface's lift-off effect during the detection procedure.
