ULTRASCHALL-PRUEFVORRICHTUNG ZUM ZERSTOERUNGSFREIEN PRUEFEN VON SCHWEISSNAEHTEN

摘要

The ultrasonic non-destructive test device for welding beads comprises two test heads arranged on either sides, one opposite the other, of the weld bead (16). Each head comprises a vibrator (67, 68) for the longitudinal defects and two vibrators (71, 72 and 73, 74) for the transverse defects. The device allows the complete and automatic test of the well bead, from the beginning to the end, for the longitudinal and transverse defects and only with two control heads (65, 66). Consequently, the overall dimensions of this device are reduced.
