TOMOGRAPH WITH AN ANTENNA ARRAY DIGITALLY FOCUSED TO ALL POINTS ADVANTAGES OF TOMOGRAPHY A LIGHT AND EASY-TO-USE DEVICE IS DESTINED FOR RESOLVE MOST TASKS OF ULTRASONIC FLAW DETECTION OF METALS AND PLASTICS VISUALIZATION MODES The A1550 tomograph offers five modes of discontinuity flaw image visualization. The mode is selected depending on the purposes of inspection and the object nature. Modes are marked with special symbols as shown below. Here are general description of them: PROVIDES QUICK, EASY AND RELIABLE LOCATION OF FLAWS THE INTERNAL STRUCTURE OF THE TESTING OBJECTS IS REPRESENTED IN REAL TIME AS CROSS-SECTION IMAGES TO MAKE RESULTS INTERPRETATION MUCH EASIER AS COMPARED TO A TRADITIONAL FLAW DETECTOR Testing object: half-space Reflector: point Sounding: direct Purpose: For objects of irregular shape, without definite thickness, or objects with rough back surface Testing object: slab, 10 < d < 100 mm Reflector: point Sounding: direct and reflected Purpose: For plane-parallel objects with known thickness Testing object: plate, d < 10 mm Reflector: point Sounding: reflected Purpose: For plane-parallel objects with known thickness, small thickness objects while finding flaws near the surface Testing object: slab or plate, d < 100 mm Reflector: flat Sounding: direct and reflected Purpose: For detection of vertically-oriented flaws and plain surfaces, mirroring the ultrasound Testing object: slab or plate, d < 100 mm Reflector: volumetric Sounding: direct and reflected Purpose: Universal mode for plane-parallel objects with known thickness and all types of discontinuity flaws QUICKNESS AND EFFICIENCY • Efficient and high-performance location of flaws in welding joints, metal objects, plastics and composite materials with documenting results in details. • The internal structure of the testing objects is represented in real time as cross-section images with 25 frames per second. • Possibility to perform ultrasonic flaw detection along the welding joint line without cross scanning, due to big aperture of the digitally focused array and scanning with virtual focus on long distances, which considerably reduces time for preparing the near-welding surface, increasing the testing productivity. • High frame rate on the screen provides scanning speed along the welding joint up to 50 mm/s. EASY DATA INTERPRETATION • Visualization of an inner structure of the testing object as illustrative and accurate cross-section images (B-Scan) in real time with easy-to-use scales of length and depth, which makes the results much easier to analysis. • Automatic and manual measuring of signal levels and coordinates and sizes of flaws. • Ranging the distance between images of flaws on the screen. TESTING RELIABILITY • The flaw detector-tomograph works basing on the digitally focused array method (DFA) reconstructing tomograms focused in every point of the cross-section, ensuring the best spatial resolution and maximum sensitivity at the whole visualized area, and also high testing productivity. • Sensitivity to different types of flaws. • Images of vertically-oriented flaws. EASY TO SET UP AND TO USE • Simple and user-friendly MENU of settings and configurations for every testing object. • Intuitive interface with shortcuts to main settings and parameters to master the device in short time. • Specialists of any qualification level can operate the device, even without introducing training. • Quick switching between TOMOGRAPH, SCANNER and FLAW DETECTOR modes. DFA is changed to a classic transducer respectively. • Replaceable acoustic modules of DFAs. OMNITUDE AND PORTABILITY • Operating in tomograph mode (B-Scan) or in traditional flaw detector mode (A-Scan). • Scanning along welding line (C-Scan) and saving results. • Small size. • The device weights only 1,8 kg. • Easy detachable lithium battery providing 8 hours of work. • Large color display showing cross-section graphic images, coordinates and signal levels. • Protective cover and a set of «hands free» belts make this device a handy tool for work in hard-to-reach places. • Works at the temperature range from - 10° to +55 °C to perform testing indoor, in laboratories or outside in severe conditions. • Nonvolatile memory for tomograms and echo-signals with the possibility to overview on a PC without special software. • USB connection for information output to an external PC. • Special software for receiving data from the device, processing, documenting in the form of tomograms and echo-signals and archiving. EXTRA FEATURES • The A-SCAN function in TOMOGRAPH mode is provided to visualize the A-Scan impulse signal, plotted by a controlled line of the cross-section. It also evaluates the flaw depth and angle of probe, ensuring correct and quick choice of a single transducer when switching to the FLAW DETECTOR mode. • Measuring signal level and coordinates of reflectors in every point of the tomogram. • Setting the scale and position of the visualization area in relation to the DFA. • Two fully adjustable 2D gates for automatic measuring of the flaw coordinates. • On-line control of a contrast tomogram. • Choice of a colour tomogram. • Creating, saving and choosing settings for a specific object. • Saving and viewing tomograms and echo-signals from the memory. • Semiautomatic sensitivity calibration by standard samples. • 2D system of spatial sensitivity adjustment to find and evaluate small flaws according to actual regulating documents and to size flaws up correctly at the whole surface of the object of inspection. • Inspection in the three-level reflector estimation system: «examination-reporting-acceptance» with colour gradation of the tomogram image levels and automatic comparison to the reference level. • Scanning along welding line with an antenna array equipped with an encoder (supplied optionally) makes it possible to get a reliable graphic view of the object inner structure in a form of C- and D- Scans. SOFTWARE With our special software ADM-IntroVisor you can send data saved in the device to an external PC so that results of inspection could be processed, documented as tomograms and echo-signals with parameters of inspection and archived afterwa
