Development of low‐cost imaging system for laser metal deposition processes

摘要: – The melt pool created by a laser is one of the most important factors affecting quality deposit in metal deposition (LMD) process. high‐intensity infrared (IR) radiation emitted saturates conventional camera sensor preventing useful data acquisition. purpose this paper to discuss development low‐cost vision system monitor size for in‐process control deposit., According black body theory, there no ultraviolet (UV) region from LMD IR and visible light are only radiations inherent UV illumination utilized along with narrow band pass filters on USB achieve clear image while process blocked out. shape were closely monitored during process., A was obtained using relatively imaging Traditional approaches systems processes use high‐speed video fitted prevent saturation sensor. Such usually complex expensive run maintain. This demonstrates an alternative lower cost method monitoring
