Edge Tracking with OCT for Remote Laser Welding (Pre-Process)

The optical coherence tomography (OCT) is an optical measuring process suitable for supervising laser welding processes. OCT monitoring permits a precise and dynamic control before, during, and after the welding process. More details on the technical setup of an OCT system are explained in the video.
OCT-based edge tracking makes it possible to guide the laser beam continuously with precision on the component. The component geometry and position are recorded and the position of the laser beam can be adjusted for a precise seam tracking in a few milliseconds immediately before the real laser welding process (Pre-Process).
