field verification | ytmf-x1 array eddy current tester: precisely tackles challenges in bar axial defect detection


metal bars serve as core basic profiles in mechanical manufacturing, metallurgy, heavy industry and other sectors. surface and subsurface cracks, corrosion and other defects on bars are major hidden hazards that compromise product quality and equipment operational safety.

these micro defects are highly concealed. conventional eddy current testing (ect) frequently suffers from missed detections, positioning deviations and blurred imaging. accordingly, testing equipment must meet extremely high standards in terms of precision and imaging performance.


to verify the practical detection performance of the equipment, we conducted scanning tests on bars with axial artificial notch defects using the ytmf-x1 array eddy current tester.

the tests fully validate the equipment’s adaptability and accuracy for typical defects on bars.

the device delivers stable and efficient scanning throughout the process. equipped with high-definition c-scan imaging technology, it can clearly visualize both internal and surface defects of bars. the c-scan images feature distinct layers and highly recognizable defect contours, with no clutter interference or artifacts.
benefiting from the ultra-flexible array probe and multi-channel array testing technology, this system breaks the limitations of conventional single-point eddy current testing. it realizes large-area coverage and blind-spot-free scanning on bar surfaces, and effectively improves the detection sensitivity for slender axial defects. defect morphology is presented intuitively via c-scan images, and all test data can be recorded and stored.

test blocks were used in this test, with metal bars serving as the test substrate. pre-fabricated axial notches were machined on the bars to simulate common axial damage and crack defects occurring during industrial production. this setup reproduces actual on-site inspection conditions to the maximum extent, ensuring all test data is authentic, valid and fully applicable to industrial scenarios.

the core advantages are fully demonstrated. all pre-fabricated axial notches on the test blocks were completely detected. the actual position, length and orientation of the defects are accurately matched and highly consistent with the imaging results. the equipment realizes perfect defect visualization, precise positioning and clear reproduction of defect morphology.
