Paper Abstract

Power lasers are more and more used in aerospace industry or automobile industry; their widespread use through different processes such as: welding, drilling or coating, in order to perform some surface treatments of material, requires a better understanding. In order to control the quality of the process, many technics have been developed, but most of them are based on a post-mortem analysis of the samples, and/or require an important financial investment. Welding, coating or other material treatments involving material transformations are often controlled with a metallurgical analysis. We here propose a new method, a new approach of the phenomena, we control the industrial process during the application. For this, we use information provided by two CCD cameras. One supplies information related to the intensity, and geometry of the melted surface, the second about the shape of the powder distribution within the laser beam. We use data provided by post-mortem metallurgical analysis and correlate those informations with parameters measured by both CCD, we create a datas bank which represents the relation between the measured parameters and the quality of the coating. Both informations, provided by the 2 CCD cameras allows us to optimize the industrial process. We are actually working on the real time aspect of the application and expect an implementation of the system.
