ABSTRACT:
A device for the free-jet ultrasonic testing of a workpiece by the transmission technique includes a first test head, serving as an ultrasound transmitter, and a second test head, serving as an ultrasound receiver. The test heads are respectively disposed on a first robot and a second robot, in each case in a freely movable manner, with at least one degree of freedom, such that they are aligned coaxially in relation to each other and perpendicular to a surface of a workpiece. The robots are positioned such that they are fixed in place on a displaceable common carrier.
