Development of Low-Cost Imaging System for Laser Metal Deposition Processes
The melt pool created by a laser is one of the most important factors affecting the quality of the deposit in a laser metal deposition (LMD) process. The high-intensity infrared (IR) radiation emitted by the melt pool saturates a conventional camera sensor preventing useful data acquisition. The purpose of this paper is to discuss the development of a low-cost vision system to monitor the size of the melt pool for in-process quality control of the deposit.
