Abstract. A theoretical model of excitation and propagation of ultrasonic waves in thin-walled soldered structure is developed. The waves in question are excited due to thermo-optical effect caused by absorption of pulsed laser radiation in the soldered thin-walled product of space-rocket technique under testing.
Keywords: ultrasonic wave, thermo-optical effect, laser radiation, nondestructive check, soldering.
