Among active methods, pulsed thermography (PT) and lock-in thermography (LT) are widely used, while frequency-modulated thermal wave imaging (FMTWI) offers superior defect detectability and depth resolution through pulse compression. This study presents an experimental evaluation on a hardened steel specimen, commonly used in the shipbuilding industry, containing a flat-bottom hole defect, using PT, LT, and FMTWI. The defect detection potential of FMTWI is further assessed through three post-processing strategies: frequency domain phase (FDP), time domain phase (TDP), and cross-correlation coefficient (CCC). Results demonstrate that the FMTWI, CCC combination yields the most reliable and high-contrast defect visualization, outperforming other approaches in both clarity and depth sensitivity.

This will significantly restrict the scope of EMAT applications. Therefore, this study proposes a novel wavelength-tunable Rayleigh wave EMAT (WT-RW-EMAT) with high conversion efficiency. This transducer consists of a periodic permanent magnet (PPM) and a coil array (CA). The PPM consists of five rectangular permanent magnets arranged side by side in opposite polarity, with the CA wound separately between adjacent magnets. This configuration generates strong horizontal magnetic fields periodically at the junctions of neighboring magnets. This allows the CA to fully utilize these strong horizontal magnetic fields for exciting Rayleigh waves to improve conversion efficiency. The wavelengths of Rayleigh waves excited by WT-RW-EMAT are tunable through phase control. A finite element model of the WT-RW-EMAT is established using COMSOL Multiphysics, and the performance of the proposed WT-RW-EMAT is studied. The effectiveness is verified by experiments. The proposed EMAT configuration improves the amplitude of the Rayleigh wave by 74.2%. The simulations and experiments showed that the wavelength of Rayleigh waves excited by WT-RW-EMAT is tunable by controlling the time delay of the excitation signal of each coil. With an increase in time delay, the wavelength linearly decreases, and the center frequency nonlinearly increases. This transducer has significant potential applications in detecting gradient properties of a medium.</p>","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"62 1","pages":"28 - 42"},"PeriodicalIF":0.9,"publicationDate":"2026-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147714852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Artificial defects were embedded in shielded metal arc welds and verified by radiography before ultrasonic inspection with 45° and 70° probes. DAC signals often exceeded reference levels, making sizing impossible. DGS was limited to flaws smaller than 10 mm and consistently underestimated size. The 20-dB drop method achieved the highest accuracy, measuring a 4.00 mm defect as 4.02 ± 0.02 mm, with stable results across probe angles.

Although dry coupling offers a more practical alternative, static models are insufficient to describe the fluctuating interface conditions encountered during scanning inspections. To address this limitation, we develop a dynamic dry-coupling model that incorporates time-varying contact stiffness, linking applied pressure, surface roughness, and material properties within the classical acoustic reflection framework. Finite element simulations using COMSOL Multiphysics were employed to determine the empirical scaling factor α, ensuring that the formulation remained physically consistent while avoiding arbitrary parameter fitting. Experimental validation was performed on a robotic ultrasonic testing platform equipped with a 5 MHz dual-element probe and a stepped 1018 steel block prepared with multiple surface roughness levels. By systematically varying scanning speed, contact pressure, and interface roughness, a comprehensive set of dynamic ultrasonic data was obtained. The results demonstrated clear periodic modulation of reflection amplitudes consistent with theoretical predictions, with discrepancies generally within ±10%.

The main idea of the method is to periodically heat the tuber surface with infrared radiation and then analyze not only the amplitude but also the phase of temperature fluctuations on the surface using a thermal imaging camera. Numerical modeling in the COMSOL environment and subsequent experiments on real samples have shown that the proposed method makes it possible to effectively detect both surface and subsurface defects (for example, dry rot) at a depth of up to 2 mm, while reducing the influence of contamination, glare, and uneven illumination due to the curvature of the surface. It has been established that low periodic heating frequencies (less than 0.1 Hz) and a heat flux density of up to 1700 W/m<sup>2</sup> should be used for optimal detection of defects at various depths.
