Paper Abstract

Laser cladding has many advantages compared to alternative non laser surface treatment processes like thermal spraying or deposition welding. It is possible to apply the laser energy into the base material in highly localized way. Therefore it is possible to build up claddings with a comparably high spatial accuracy. However, the efficiency of the process is generally low. For example the energy in terms of conducted heat into the base material beside the melt pool is lost. It can be shown that the so called heat conductivity losses can be reduced by optimizing the process parameters like scan velocity and beam intensity. Moreover, it was found that by coupling significantly more energy into the powder, both the energetic efficiency and the deposition efficiency were increased significantly. In this publication it is shown that it is possible with right parameter adaptation to reduce the processing time while simultaneously increasing the energetic process efficiency.
