Research on an Online Monitoring System for the Smoothness of Laser Cladding Pool Based on CCD
Due to the high temperature and high brightness during the laser cladding process,it is impossible to accurately determine the cladding effect in real-time.Use CCD camera combined with smoothness monitoring algorithm to monitor the morphology of the molten pool to determine the cladding effect.The results indicate that excessive laser power or slow scanning speed can lead to poor smoothness of the edge of the molten pool,leading to the perception of unsuitable cladding parameters.To prevent melting of the substrate,the machine can be shut down in a timely manner based on the monitoring effect.It was found that there is a negative correlation between laser power and the smoothness of the molten pool edge.
