Abstract
The invention relates to an ultrasonic testing device and to a method for nondestructively testing a component, in particular a fiber-plastic composite component, having: an ultrasonic testing head; and a liquid nozzle with a liquid inlet, a liquid outlet, and an inner surface which tapers towards the liquid outlet, wherein the liquid nozzle has at least one liquid guiding rib which protrudes inwards into the sound chamber from the tapering inner surface of the liquid nozzle upstream of the ultrasonic testing head.
Claims13
An ultrasonic testing device for non-destructively testing a component, having:
- an ultrasonic testing head,
- a liquid nozzle with a liquid inlet, a liquid outlet, and an inner surface which tapers towards the liquid outlet,
- wherein
- the liquid nozzle has multiple liquid-guiding ribs, which protrude inwards from the tapering inner surface of the liquid nozzle into a sound chamber in front of the ultrasonic testing head,
- a height of the liquid-guiding ribs decreases towards the liquid outlet, and
- the inner longitudinal edges of the liquid-guiding ribs run substantially parallel to one another.
A testing system having a manipulation element, having a robot arm, on which a tool having an ultrasonic testing device is arranged, the device having an ultrasonic testing head, a liquid nozzle with a liquid inlet, a liquid outlet, and an inner surface which tapers towards the liquid outlet wherein the liquid nozzle has multiple liquid-guiding ribs which protrude inwards from the tapering inner surface of the liquid nozzle into a sound chamber in front of the ultrasonic testing head, wherein a height of the liquid-guiding ribs decreases towards the liquid outlet, and wherein the inner longitudinal edges of the liquid-guiding ribs run substantially parallel to one another.
A method for non-destructively testing a component, having the steps of:
- providing an ultrasonic testing device having an ultrasonic testing head, a liquid nozzle with a liquid inlet, a liquid outlet, and an inner surface which tapers towards the liquid outlet wherein the liquid nozzle has multiple liquid-guiding ribs which protrude inwards from the tapering inner surface of the liquid nozzle into a sound chamber in front of the ultrasonic testing head, wherein a height of the liquid-guiding ribs decreases towards the liquid outlet, and wherein the inner longitudinal edges of the liquid-guiding ribs run substantially parallel to one another,
- generating ultrasonic waves using the ultrasonic testing head,
- supplying a liquid flow into the liquid nozzle via the liquid inlet,
- conducting the liquid flow along the inner surface of the liquid nozzle to the liquid outlet, wherein the liquid flow is guided with the aid of the liquid-guiding rib.
