Paper Abstract

The infrared thermographic nondestructive inspection technique is a quality inspection and stability assessment method used to diagnose the physical characteristics and defects by detecting the infrared ray radiated from the object without destructing it. Recently, the nondestructive inspection and assessment that use the ultrasound-infrared thermography technique are widely adopted in diverse areas. The ultrasound-infrared thermography technique uses the phenomenon that the ultrasound wave incidence to an object with cracks or defects on its mating surface generates local heat on the surface. Aiming to establish a convergence non-destructive evaluation system, this study used the control technology of an ultrasound exciter as an association technology that satisfies various required conditions in order to control the ultrasound excitation time and output, and performed basic research for establishing a convergence non-destructive system by applying the Lock-in technology that improves the infrared thermography detectability. Also it compared and analyzed the test result by using COMSOL Multiphysic, a finite element analysis program.
