The invention relates to a method and to a corresponding device in which irregularities regarding each detected measurement position within a measurement surface are detected using a local measurement density. Each echo signal received in response to each detected measurement position is then weighted in order to generate an image using a data processing device such that the irregularities are adjusted.

A method and device for the ultrasonic testing of test objects by means of a test head. A computer device directly acquires, during a SAFT analysis for determining points in time of the amplitudes to be summed up from among the image time signals, a propagation time, which depends on the test head, from the test head positioned at a measuring point to the location of each of a plurality of voxels and uses the propagation time for calculating an amplitude total for the plurality of voxels.

In order to support an inspecting person in a method for the manual non-destructive inspection of a test object, a detection device is provided for detecting three-dimensional surface coordinates of a region to be inspected on the test object and for continuously determining positions and speeds of an inspecting tool relative to the test object Discrete position values and speed values of the inspecting tool for the respective measurement time points are stored by a storage device. A computing device determines the share of an already inspected region in relation to the total region of the test object to be inspected. The method and device can be used for manual inspection of test objects having a plurality of different shapes. The inspecting person is effectively relieved and the process for the non-destructive inspection is documented in order to guarantee a complete inspection.

Ensuring inspection coverage for manual inspection

A device and a method for detecting at least one defect in a test object (). At least one test head () radiates an ultrasonic signal at different measuring points (MP) into the test object () with each point at an insonation or radiation angle (&#x3b1;) in order to ascertain multiple measurement data sets (MDS). The angle is constant for each data set (MDS). An analyzing unit () carries out an SAFT (Synthetic Aperture Focusing Technique) analysis for each ascertained measurement data set (MDS) using a common reconstruction grid (RG) inside the test object () in order to calculate an SAFT analysis result for each measurement data set (MDS). The analyzing unit () superimposes the calculated SAFT analysis results in order to calculate an orientation-independent defect display value (S) for each reconstruction point (RP) of the common reconstruction grid (RG).

Method and device for detecting defects within a test object

A method for the ultrasound check of a test object involves moving a test probe along a test probe surface and sending ultrasound impulses into the test object by the test probe. Respective echo signals corresponding with the emitted ultrasound impulses are received by the test probe. An image of a predetermined test region of the test object is prepared on the basis of an overlapping and averaging of amplitude values of the received echo signals by a data processing unit. The respective position of the test probe when sending the ultrasound signals and/or when receiving the corresponding echo signals is captured by a capturing unit. The respectively captured positions of the test probe are considered when creating the image of the test region of the test object.

A technique is provided for determining an orientation of a defect present within a mechanical component using at least one ultrasonic head that applies ultrasonic signals to the mechanical component starting from various measurement points. Echo ultrasonic signals reflected by a point to be analyzed present within the component back to the measurement points are received by the same or a different ultrasonic head. A data processing unit analyzes the received echo ultrasonic signals as a function of a sound emission direction between each measurement ping and the point to be analyzed for determining the orientation of the defect. A distance between the measurement point and the point to be analyzed is calculated for every measurement point as a function of a signal propagation time between the point in time of emitting the ultrasonic signal and the point in time of receiving the echo ultrasonic signal reflected by a defect.

In a device and method for non-destructive materials testing with at least one ultrasonic transducer, the transducer is able to be moved by a movement system in at least one direction to a workpiece surface. The emission of ultrasonic by the ultrasonic transducer is able to be synchronized with the activation of the movement system so that electrical interference caused by the movement system occurs at times at which no echo is expected for ultrasonic emitted by the transducer. The method and device can be applied to non-destructive materials testing with ultrasound.

Method for synchronization of ultrasonic transducers in a movement system

Calibration for a nondestructive ultrasonic material testing system is provided, the system having a multiplicity of ultrasound transducers which are linearly movable as a whole but are arranged fixed with respect to one another, for example mounted fixed in a single sensor holder. In order to achieve optimal alignment of the sensors with a specimen, the mechanical tolerance-induced offset between the beam direction of the ultrasound transducers and the ideal beam directions is found, for example with the aid of a mean straight line. It is then minimized by using the available degrees of freedom of the sensor holder, for example possible tilting of the sensor holder.

Calibration for a nondestructive material testing system

Calibration for an ultrasonic nondestructive materials testing system is specified, the system having an array of ultrasonic transducers which can be linearly moved and pivoted. In order to compensate for the offset between the beam direction of the ultrasonic transducers and the rotation point of the pivoting system or another desired point of the transducers, this offset is determined using a calibrating body which is, for example, spherical.

One surface of a component is obliquely ensonified through a liquid or gaseous first medium with a checking sound beam produced by a transmission/reception transducer for defect investigation of the component. A response sound beam, which is reflected back from the surface to the transmission/reception transducer, is received and its delay time in the medium between the transmission/reception transducer and the surface is evaluated. The delay time in the medium determined in this way is taken into account for localization of a defect within the component.
