How does the eddy current testing method detect subsurface flaws in stainless steel animal sculptures?

Eddy current testing is a non-destructive method widely used to detect subsurface flaws in stainless steel animal sculptures. This technique relies on electromagnetic induction, where an alternating current is passed through a coil, generating a magnetic field. When the coil is brought near the stainless steel surface, eddy currents are induced in the material. Any subsurface flaws, such as cracks or voids, disrupt these currents, altering the coil's impedance. By analyzing these changes, inspectors can identify and assess hidden defects without damaging the artwork.

Stainless steel animal sculptures, often exposed to environmental stress, require thorough quality checks. Eddy current testing provides a fast, accurate, and cost-effective solution, ensuring structural integrity and longevity. This method is particularly valuable for intricate designs where visual inspection alone is insufficient. By leveraging advanced technology, artists and conservators can preserve the beauty and durability of these unique creations.
