Systems and methods for improved visualization of non-destructive testing (NDT) measurements are provided. A probe can be employed to acquire NDT measurements of a target. Images of the target can also be captured during testing. The captured images can be analyzed to identify selected objects therein (e.g., the target, the probe, etc.) Graphical user interfaces (GUIs) including the NDT measurements can be further generated for viewing in combination with the target. In one aspect, the GUI can be viewed as a hologram within a display of an augmented reality device when viewing the target. In another aspect, the GUI can be projected upon the target. The GUI can be configured to overlay the NDT measurements at the location where the NDT measurements are acquired. This display of the NDT measurements can help an inspector more easily relate the NDT measurements to the target and improve reporting of the NDT measurements.

Augmented reality in ultrasonic inspection

The invention relates to an ultrasound control device for non-destructively inspecting a workpiece. The inventive ultrasound control device comprises a transmitting-receiving sensor provided with an element for connecting to the input surface of a controlled workpiece, a transmitter which is connected to the sensor and sends pulses produced thereby to said sensor, a receiver connected to the sensor and a screen which is connected to the receiver for displaying electric echo signals received by the receiver. The sensor transmits ultrasound pulses which, on one hand are reflected by the input surface and return to said sensor, and penetrate into the workpiece and are reflected at least once by the back wall thereof, on the other hand. Said ultrasound control device also comprises a bar display for visualising the received electric echo signals. At least one signal value displayed on said display in a real time results from one of electric echo signals reflected by the input surface: an input echo reflected by the input surface, at least one echo from the back wall and/or one signal calculated on the basis of several echoes reflected thereby.

Ultrasonic inspection apparatus for inspecting a workpiece

The invention relates to a method for determining the threshold value of screens which enable an evaluation of a sound coupling during the ultrasound testing of a series of spot welding joints of a selected type. Initially, a geometrical minimal thickness dMin is established for the spot welding joints. At least one echo of the front surface (entrance echo) is received in addition to one echo of the first reflection on a rear wall of the spot welding joint (first rear wall echo) and at least one further (n-th) rear wall echo. The propagation time tMin of the ultra sound pulse is defined for the path to the front surface to the rear wall and back to the front surface at a minimal thickness dMin and a propagation time tT for the total thickness. A first screen (B) is set for the signal of the rear wall echo, starting at a moment in time tS=tE+tMin&#x2212;tSA and ending at a moment in time tT=tE+tT+tSE, whereby tSA and tSE are additional small security measures. An n-th screen is correspondingly determined for the n-th rear wall echo. The testing head is oriented differently.

Method for determining temporal and amplitude threshold values of gates during ultrasound testing of spot welding joints

The invention relates to an ultrasonic probe comprising: &mdash;a housing ( ), which accommodates an ultrasonic transducer and has a contact surface for making contact with the surface ( ) of a body ( ) to be inspected; &mdash;at least one digital camera ( ), which is allocated to the housing ( ) and which is aligned in such a way that it registers the surface ( ) of the body ( ) and supplies a respective electronic image of sub-sections of the surface ( ) of the body ( ) at intervals; &mdash;a circuit for image processing ( ), which has an image memory ( ) for at least one electronic image that has been registered by the digital camera ( ). Said circuit also comprises a comparator ( ) that compares two electronic images of the body ( ) to be inspected, registered by the digital camera ( ) at different times and that determines the displacement of the housing ( ) in relation to the surface ( ); and a displacement memory ( ), which contains the displacement of the housing ( ) and the current position of the housing ( ) in relation to the original location ( ).
