Abstract
There is provided a diagnosis device of a joint of sheet metal, including: a detector that irradiates an ultrasonic wave to a diagnosis object including a first medium and a second medium having a joint, and senses a reflection signal reflected from the joint and a reflection signal reflected from the joint and thereafter, reflected toward the joint on an inner surface of the first medium; a delay material positioned between the detector and the diagnosis object to delay the reflection signal; and a diagnoser that calculates and displays a signal ratio by receiving the reflection signals sensed by the detector.
