Desarrollo de un Software de asistencia para el Análisis e Inspección de Placas Radiográficas de Soldadura

Abstract

Through this project, an assistance software for the analysis and inspection of radiographic welding films (Watching Defects 1.0, WD 1.0) is developed. To do this it was necessary the use of a group of radiographic films, which were provided by the ENDE Cía. Ltda. Company and were digitalized in the non-destructive test laboratory at National Polytechnic School. So, it was created a scanned data base of radiographic films. The assistance software contains multiple assistance windows also allows a connection between the measurement commands of discontinuities, image processing (by contrasting images with the use of the RGB color scale of pixels) and the creation of reports. The methodology used includes the development of a software based on an object-oriented programming language. This allows us entering the digitized radiographs, processing and filtering them, searching for the best appearance condition to make the measurements for discontinuities and comparing the partial results with the limits of admissibility dictated by the appropriate norms. The software concludes with the creation of a report which includes the most relevant variables in the analysis and inspection of the radiographic films. Based on the characterization in black which lets the identification of the acceptable ranges for the filtering, it is recommended the use of the green filter with brightness of 16%G.
