Calibration test piece unit and nondestructive infrared thermography system and method using thereof

摘要

The present invention is optimal ultrasound infrared radiation detection unit calibration specimens, with a specimen that unit Calibration method, using a test piece for the thermal non-destructive testing system and method for detecting unit. More specifically, the check for displacement with the ultrasonic non-destructive in the infrared thermal image with the ultrasonic testing apparatus for detecting a defect in the test piece, the test piece in the unit for calibration, a calibration test piece contains a defect portion is formed having a certain width, the test piece There is a maximum amount of heat generated is in accordance with the ultrasonic vibrations of a certain size with a pre-measured, the displacement of the ultrasonic non-destructive thermal imaging confirmed that with the test sample to determine the calorific value of the test piece during the test, the ultrasonic detecting infrared radiation, characterized in that the best possible calibration It relates to a calibration test piece unit. ;
