Lub longitudinal thiab transverse nthwv dej tshaj tawm ntawm ultrasonic tsis nyob rau hauv txhuas yog 6300m / s thiab 3080m / s feem 12.
Ultrasonic flaw detectors siv ultrasonic nthwv dej kom nkag mus rau saum npoo ntawm cov khoom raug kuaj ntawm qee qhov ceev, zaus, nce thiab lwm yam tsis xws luag, thiab xyuas seb puas muaj qhov tsis xws luag, tawg, npuas thiab lwm yam caws pliav hauv cov khoom los ntawm kev tau txais lub suab tsis zoo. Qhov tseeb ntawm lub suab nrawm teeb tsa ncaj qha cuam tshuam qhov tseeb ntawm qhov ntsuas. Yog li ntawd, thaum siv lub ntsuas ntsuas ultrasonic, nws yog ib qho tseem ceeb los xyuas kom meej qhov tseeb ntawm lub suab tshaj tawm tsis.
