Abstract
Vibrothermography nondestructive evaluation, also known as Sonic IR and thermosonics, finds cracks by vibration-induced crack heating. The most common vibration source in the industrial practice of vibrothermography is the ultrasonic welder, which generates high amplitude single frequency vibration. In most applications, the single frequency excitation of the welder is transduced into the broadband resonances of the specimen by repeated impact between welder tip and specimen. We present progress in modeling and verification of a predictive model for ultrasonic welder excitation for vibrothermography
