Real-Time Quantitative Ultrasonic Inspection
Most frequently applied ultrasonic inspection techniques measure the reflectivity of geometric scatterers that are caused by impurities, flaws and defects in the material. Based on the echo sounder principles, the reflector has to be insonified by directed sound pulses. This requires a large number of transducers with different incident angles and sound field patterns, which are more and more r...
متن کاملUltrasonic Inspection of Near Net Shape Disks
With new fabrication technologies, disks for gas turbine engines can be manufactured from high strength ~terials with a substantial cost savings. Utilization of these technologies to their full potential is currently limited by the ability to perform a reliable high resolution, high sensitivity ultrasonic inspection. A computer automated inspection system is being developed to inspect near-net ...
متن کاملIn-Line Inspection using Ultrasonic Technology
Ultrasonic (UT) is currently the most accurate and reliable In-Line Inspection (ILI) technology available in the market. These UT ILI Tools will record data while travelling through the pipeline from Launcher to Receiver. In most cases, the Pipeline Operator does not need to make major adjustments to their pipeline's normal operating conditions when conducting the inspection survey. Piezo-elect...
متن کامل3D-SAFT Ultrasonic Inspection Equipment “MatrixeyeTM”
3D ultrasonic inspection equipment “Matrixeye” can visualize defects as 3D image with good resolution by the 3D SAFT (Synthetic Aperture Focusing Technique) imaging method. High-speed 3D SAFT imaging process can be achieved by the developed parallel signal process of the ultrasonic echo data collected by a linear or a matrix-array ultrasonic probe. It has the following features. •3D image with ...
متن کاملAutomatic Detecting Disbonds in Layered Structures Using Ultrasonic Pulse-echo Inspection
A method for automatic detection of disbonds in layered structures based on time-frequency representation of the ultrasonic signals acquired during ultrasonic inspection is presented in the paper. The detection is performed by a multilayer perceptron neural network using features extracted from the time-frequency representation as inputs. The performance of the detector is demonstrated using da...
