Closed Loop Control of Penetration Depth during CO<sub>2</sub> Laser Lap Welding Processes
In this paper we describe a novel spectroscopic closed loop control system capable of stabilizing the penetration depth during laser welding processes by controlling the laser power. Our novel approach is to analyze the optical emission from the laser generated plasma plume above the keyhole, to cal...
