ABSTRACT:
The invention relates to a testing device for ultrasonic bar (30) testing, comprising a container (20) a) with a chamber disposed therein where the ultrasonic testing is carried out which b) is provided with at least one through-passage (28) for bars which are to be tested and which c) has at least one inlet and at least one outlet for a coupling fluid (52), especially water, whereby the inlet and outlet are arranged in such a way the coupling fluid (52) is circulated around the bar (30) in a cross-wise direction in relation to the longitudinal direction thereof (32), in addition to comprising at least one ultrasonic test head (46) which is directed at the bars (30). The chamber has a non-circular cross-section perpendicular to the longitudinal direction (32) of the bars (30) and the cross-section of the chamber is adapted to the profile of the bars (30) in such a way that the width of a gap (42) running between the bars (30) and the wall (40) of the chamber is substantially maintained.
