Abstract
The use of CCD cameras for recording the area of high power radiation exposure during laser cladding process is an urgent task in a view of low cost of used equipment and high information content of obtained graphic data. This approach allows real-time recognition of geometric primitives in melt pool area and based on their analysis to evaluate the quality of processing operation. The main objective of the study was to eliminate, by using external illumination, a large dynamic difference in brightness, which negatively affects the quality of images obtained. As a result of the experiments, it was found that the most effective configuration of the video recording system for laser powder surfacing process is the location of camera and illumination module against the direction of head movement. The developed illumination system for the radiation exposure area made it possible to provide conditions acceptable for the automated recognition of images obtained by the CCD camera.
