Advances of OCT Technology for Laser Beam Processing

Precision and quality during laser welding

Abstract

Optical coherence tomography (OCT) is an innovative sensor 3D measuring system for automated laser processing, in particular laser welding. It facilitates laser beam positioning, process monitoring, and quality control with the required precision and guarantees process flexibility, stability, and traceability. To ensure smooth seam tracking  for time- and cost-effective line production, Lessmüller  Lasertechnik OCT systems offer the automated recognition and digitalization of joints for precise lateral and axial positioning. It provides industrial solutions for the online inspection of the keyhole to enable consistent and high quality welds.
