Multichannel Ultrasonic flaw Detector AUGUR-ART

The AVGUR-ART R flaw detector in a portable design is supplied as a monoblock, including multi-channel electronics in a configuration from 32x32 to 64x128PR with additional support for up to 2 pairs of TOFD channels.

The ultrasonic multichannel flaw detector with digital focusing and automated scanning by antenna arrays AUGUR-ART is designed for:

- identification and visualization of discontinuities, determination of their sizes and coordinates, amplitudes of echo signals.

- conducting automated ultrasonic testing (AUZK) of welded joints and the base metal of equipment, parts, pipelines and other metal products, their alloys and other materials, including objects made of pearlitic and austenitic steels with a thickness of 6 to 500 mm.

Inspection using the AVGUR-ART flaw detector can be carried out at facilities located both in the process of construction (manufacturing, construction, installation), and during operation.

The operating principle of the flaw detector is based on the acoustic echo method of non-destructive testing using antenna arrays (AR). The flaw detector operates in the digital antenna focusing (DFA) mode, which has a number of advantages compared to the phased array (FR) mode.

The flaw detector supports data collection over 64 channels in the DSC mode. The flaw detector implements the TOFD operating mode.

DSC mode is a technology of obtaining acoustic images with continuous focusing at all points of the image. In the CFA mode, at the first stage, data collection is performed when enumerating all the emitter-receiver combinations for a linear AR, and at the second stage, mathematical processing of the obtained data is performed using the Raman SAFT (C-SAFT) algorithm. When using DSC, the same and high resolution is provided throughout the image; a coherent image is formed in only one layer. Alternative names of the CFA mode in foreign sources are Full Matrix Capture (FMC) or Sampling Phased Array.

To ensure high resolution and increase the signal-to-noise ratio when controlling thick-walled objects, two versions of DFAs with synthesizing apertures are used due to the precision mechanical movement of the AR along and across the axis of the welded joint; then, joint mathematical processing of the received echo signals is performed using the algorithms CFA-X, CFA-Y, CFA-XY.

SOFTWARE FOR DEFECTOSCOPE AUGUR-ART

The flaw detector AVGUR-ART is equipped with software (software) that controls the flaw detector operation, collection, systematic long-term storage and processing of data using the C-SAFT algorithm and other methods. The flaw detector software package includes the “AUGUR-ART Registration” program, designed to configure control parameters, visualize discontinuity images, collect control data, the “AUGUR-ART” verification program, designed to check the parameters of a flaw detector’s transceiver path used by the AR and the “ Data Analysis ”, intended for processing and visualization of AUZK data.

AVGUR-ART software is installed on the control computer and at the workplace for data processing and archiving.

Scanning devices are used with the AVGUR-ART flaw detector, which allow you to move the antenna arrays manually or in an automated mode along one or two coordinate axes.

The choice of the type of scanning device is determined by the parameters of the control object.

Scanning devices can be understaffed with a battery scanner control unit and clamps for working with flaw detectors from other manufacturers. For special control tasks, specialized SCs can be developed.
