3-D Data Plotting: A Useful Tool for PAUT

摘要

The paper presents different aspects of data plotting (2-D bitmap images) into 3-D complex parts, such as turbine blades, rotor steeples, welds and steam chest valves. Extension to defect reconstruction, defect comparison to other methods (magnetic particles, optical, fracture mechanics and/ or designed parameters) is also described. Applications to beam simulation, and to multiple frames plotting is also illustrated. Data plotting in combination with simulation and ray tracing helped optimizing the probe design, the inspection parameters and namely provides a valuable tool for technician training. Defect parameters are within the following tolerances: location: + - 1 mm, angle = + -1 deg, length: + - 2 mm and height: + - 1 mm. Some aspects of real 3-D data acquisition and analysis are commented and suggested.
