Abstract:

To address the lack of efficient nondestructive testing solutions for buried defects in high-temperature equipment, this paper presents an experimental investigation and engineering application of electromagnetic ultrasonic SV-wave oblique-incidence imaging technology. A defect localization method was derived based on the operating principle of the electromagnetic ultrasonic SV-wave. Verification of defect localization and quantification was carried out using fabricated grooved and butt-weld blocks. The proposed method was then applied to the practical inspection of high-temperature heat exchangers. Results from both laboratory tests and field applications demonstrate that the method enables accurate localization and quantitative detection of typical internal defects in high-temperature equipment.
