Stationary device for transmission τοπ. Ultrasound on moving bodies, especially sheet metal »

In the ültraachall-liaterialpriifong does the transmission of ultrasonic waves to moving test objects _? especially sheets, Bändevt rods etc _o considerable difficulties, especially when the surfaces, but are not "raw smooth much as generally in heavy plates in Warsraaizwerkan etc _0, that is," To au consider such sheets, rerschiedene Torschläge 3ind been made of this , for example, the sheet along out in a stationary water-filled bath, while si "h bsw on the opposite sides of the sheet of TJltraschallsender is" receiver. when sheets or strips, which is longer than the trough are _s 3 _e B <, wherein continuously advancing Bleehbändera, but one is forced., rorzusehen Sin "and exit windows in the walls of the tub.

With the stationary device after the fire; are these Disadvantages very simply by terminating that for transmission of the ultrasound on moving bodies * especially metal sheets, the or the ultrasonic transmitters or receivers in the bottom of a tub are arranged, which can be charged with coupling liquid in such a way that it overflows continuously, while the body, especially the sheet metal, over the rinsed edge of the tub
