摘要： PURPOSE: A defect detection method using a defect detection apparatus is provided to detect the location and size of a defect by analyzing the elastic wave transmitted along the target object to a junction. CONSTITUTION: A defect detection method using a defect detection apparatus is as follows. A target object in which multiple composite members are combined via a junction is prepared(S100). A sensor assembly changing the elastic wave created in the target object into electric signal is installed on top of the target object(S300). Power is applied to a pulse generator which generates pulse when provided with power(S400). The pulse generated in the pulse generator is changed into ultrasonic wave and it is provided to the target object(S500). The elastic wave transmitted through the target object to the junction is received in multiple receiving sensors and electric signal is generated by the multiple receiving sensors(S600). The electric signal generated in the receiving sensors is amplified by an amplifier(S700). The amplified electric signal is collected, stored, and displayed by a display device(S800).

In this, a coupling liquid medium is supplied to the probe 10 in accordance with the peripheral speed of the roll to be tested. Depending on the height of the reflected waves measured, the grinding allowance of the roll is determined, and the roll is ground according to the thus-determined grinding allowance. The roll may be tested while being partly ground, and the optimum grinding allowance of the roll may be determined.
