Abstract Sonic infrared (SIR) imaging is an original hybrid nondestructive evaluation (NDE) technique that has seen rapid acceptance in the industry. A single-tone ultrasonic wave in the 15–40 kHz range is induced to the specimen under inspection through a high-power ultrasonic plastic welder. Heating duration is equal to the ultrasonic excitation duration. In a previous article, an analytical model for depth profiling using SIR NDE was presented. According to the proposed model, material thermal properties, defect size and ultrasonic excitation duration influence defect characterization and contribute to the total temperature-time curves. In this paper, heating duration effect on the quantitative estimation of flaws using sonic infrared nondestructive evaluation was investigated.

We investigated effects of contact gap on magnetic nondestructive evaluation technique using a magnetic single-yoke probe. Firstly, we evaluated hysteresis curves and impedance related to permeability of the material measured by a single-yoke probe, when an air gap length between the probe and specimens changes. The hysteresis curve gradually inclines to the axis of the magneto-motive force and magneto-motive force at which the magnetic flux is 0 decreases with increasing the gap length. The effective permeability also decreases with increasing the gap thickness. The incremental of gap thickness increases the reluctance inside the magnetic circuit composed of the yoke, specimen and gap, which results in the reduction of flux applying to specimen.
