Description

Ultrasonic transducer calibration device {ULTRASONIC PROBE CORRECTION DEVICE}

The present invention relates to an ultrasonic transducer calibration device.

Among non-destructive inspection techniques, there is an inspection using ultrasonic waves as a representative technique for detecting defects in industrial equipment (eg, welding parts of large structures) and evaluating reliability.

A non-destructive inspection device using ultrasound consists of a device in charge of data acquisition and analysis, and a probe that directly acquires data by contacting the inspection surface. The non-destructive testing device uses the precision-machined calibration block before field application to calibrate the analysis device and the transducer. How to set up the device. When setting, the most important thing is to bring the transducer in close contact with the surface of the calibration block with the same force. If the force is irregular, it becomes difficult to secure the reproducibility of the calibration value.

The conventional method is a method of adjusting the setting value of the equipment by pressing the transducer with the power of a human hand when setting the non-destructive testing device and checking the sensitivity or strength of the signal. The reproducibility of the calibration value was also deteriorated by the force.

In addition, in order to find the defects of the correction block, the transducer must be transported in close contact with the surface.

The transducer should be moved without shaking because it is in close contact with the inspection surface during movement, but other conventional mechanical contact methods have tried to increase the adhesion by placing a spring or a mechanism capable of applying an external force to the upper and lower portions of the contact surface. However, in the case of this method, the reliability of the calibration value was lowered by causing the transducer to vibrate, failing to cope with the irregular external force generated on the surface of the transducer and the test body during the process of adhering the transducer.
