Patent ID: 8850894

Claim:
A method for ultrasonic testing by means of a local immersion technique of a stringer component section of a flat component with a device comprising a test head assembly mounted as moving floatingly by a holding device in a Y-direction longitudinally, the test head assembly comprising: a test head that can be connected to an automatically actuated handling device by the holding device; a test head holder; and a counter-holder, wherein the test head holder and the counter-holder are mounted floatingly along a guiding rail running in an X-direction transversely to the stringer component section, the method comprising: steering the test head holder and the counter-holder with an actuation element from a closed position to an open position such that the test head assembly is positioned by the handling device over the stringer component section to be tested; steering the test head holder and the counter-holder with the actuation element from the open position to the closed position, wherein the test head holder and the counter-holder are fitted by applied force to side surfaces of the stringer component section; and moving the test head assembly in a longitudinal direction to the stringer component section in a fully automated manner according to a preset dataset describing the course of the flat component and/or the stringer component section, wherein the contour changes of the stringer component section and/or the flat component are balanced by the test head holder and the counter-holder which move at least in the X and Y-directions.
