Title:
Holistic sensor concept for process control and quality assurance in laser beam welding based on Optical Coherence Tomography 
Abstract:
Optical Coherence Tomography (OCT) enables the acquisition of direct information about the geometry of the process zone during laser beam welding. The measuring principle allows for spatial and temporal highly accurate measurements that are hardly affected by process emissions or metal vapor/plasma. A novel sensor concept based on OCT was evaluated for both multi-mode and single-mode laser radiation as well as for fixed and remote optics. The sensor was equipped to a 3D scanner unit allowing for...    »
