Abstract
The present invention relates to an ultrasonic testing apparatus with a variable frequency, which can automatically change the frequency according to thickness and thereby detect internal defects in objects having various thicknesses. The ultrasonic testing apparatus may comprise: a nozzle jetting a medium toward an object so as to form a medium column; and a plurality of probes disposed in the nozzle so as to generate ultrasonic waves.
Claims13
An ultrasonic testing apparatus, comprising:
- a nozzle jetting a medium towards an object to form a medium column;
- and
- a plurality of probes disposed on the nozzle to oscillate an ultrasonic wave, and
- an ultrasonic reflector rotatably installed between the plurality of probes in the nozzle so that an ultrasonic wave of a probe selected from the plurality of probes is transmitted to the object.
