1 M2M GEKKO State-of-the-art phased-array flaw detector with TFM

2 USER FRIENDLY FLAW DETECTOR Gekko is the only compact phased-array ultrasound testing (PAUT) instrumentation offering intuitive PA features and real-time total focusing method (TFM). UNIQUE SET OF NDT TECHNIQUES With a 64-channel parallel architecture, Gekko is the only flaw detector offering conventional UT, standard PAUT, TOFD and real-time Total Focusing Method (TFM). COMPLETE TOOLSET All Gekko techniques (UT, TOFD, PAUT, TFM) are available for conventional and phased-array probes as well as dual array probes (linear and matrix). Delay laws can be calculated onboard avoiding the need to import them from a PC. With a fast SSD hard drive, operators can store large inspection files (10 Gb) and analyze them on the spot using the 10.4 touchscreen. Incremented data saving and automatic reports can be customized and exported as PDF files. Data can also be exported for analysis on a PC using the free viewer provided with Gekko. EASY INTERFACE Gekko s user-interface is developed to ease the work of operators from level 1 operators to experts. Using simple but powerful wizards, users can customize reliable field-ready applications. Thanks to visual libraries and dedicated apps, the risk for errors is reduced while making the inspection easier and faster. GUIDED Step-by-step guidance is offered throughout the complete inspection process, including equipment definition, calibration and acquisition. Gekko offers 3-click calibration tools for probe balancing, material calibration, wedge calibration, TCG and TOFD, for quicker and easier code-compliant inspections. intuitive and guided GUI 2PA and 3D representation

3 COMPLETE NDT TOOLSET Some procedures require standard UT, others TOFD or PA. With Gekko, all UT-techniques are included to offer a versatile and field-ready equipment. WELD INSPECTION Several features such as weld overlays, exact delay laws, 800% dynamic range and 3D corrected images ease the diagnostic to detect and size flaws. Combining various techniques and using up to 8 groups in a single pass substantially increases the productivity of inspections. Gekko is compatible with scanners and accessories from various vendors. NOZZLE INSPECTION With the possibility to define nozzle type geometries on-board, the Gekko can be used for 3-axis encoded nozzle inspections (scan, index and skew). Sscan images superimposed on the Cross-section overlays of the nozzle are calculated as the operator moves the probes. CORROSION MAPPING Gekko can be used with Chain scanners for corrosion mapping. Real-time data is displayed allowing corrosion detection. Cscan amplitude and time of flight are available.

4 HIGH-RESOLUTION FLAW DETECTOR For unparalleled resolution detection and characterization, Gekko offers the real-time Total Focusing Method (TFM) imaging. REAL-TIME TFM TFM is a powerful technique that focuses at each point of a user-specified zone for accurate defect characterization and high-resolution imaging. Realtime imaging with speed of up to 30 frames per second can be achieved, for clear image and defect contouring. The TFM has a 256x256 pixels image resolution (65K points focusing). TFM-scan C-scan TFM EXTENDED TFM IMAGES A-B-S-C Scan + 3D views are already available for standard PA. Gekko extends all those views to TFM allowing an operator to use advanced imaging in a familiar environment.

Corrosion till 1 mm under the surface Detection of inclined area Courtesy of Insitut de Soudure 0.5 mm pitting detection TRUE IMAGING OF 2-MM ELLIPTICAL FATIGUE CRACK Sizing of defects possible even without a diffraction signal. True-shape imaging of defects. 3-AXIS POLAR SCANNER FOR COMPOSITE INSPECTION 3-axis polar scanner motion can be read by the Gekko and transformed into a X, Y Cscan for composite inspection. Gekko data files can be up to 10 Gb. D-Scan and TFM reconstruction Cartography acquisition and 3D view
