Within this paper, we present a closed-loop control system for beam positioning during laser deep penetration welding of sheet metals. The system is comprised of a high-speed camera arranged coaxially to the laser beam on a welding head and linear stages for positioning of the specimen. It is shown that the keyhole front morphology correlates with the position of the seam in butt joint configuration. Within our closed-loop control prototype, this correlation is extracted by an image processing algorithm in a real-time environment. First experiments show that our system is able to adaptively correct the beam position with sufficient accuracy.
