Scanner-based laser cladding

An innovative laser cladding technology based on laser scanning is presented. The variable scan width allows adjusting the dimensions of the weld seams on-line in a broad range for a flexible adaption of specific requirements concerning the part's geometry. Additionally, an enhancement of the deposition rate is achieved. Automated adaption of the laser power with regard to the processing speed allows for a constant weld seam quality in curves. Furthermore, the feasibility of replacing edges by weld seams and restoring the initial part geometry is demonstrated.
