Coaxial Laser Cladding of Stelitte:Analysis of Process Parameters

The paper summarizes the results of first series of laser cladding experiments. New system combining the solid state disc laser with power up to 5.3 kW and cladding head with coaxial powder feeding was used. The powder used in experiments was Stellite 6. The experiment was design to observe the influence of main processing parameters including laser power, processing speed and powder feeding rate on the basics single clad characteristics. The main goal of the work was to discover possibilities and limitation of the new cladding system, verify the expected dependencies between of process parameters and the single clad geometry and to indentify the optimal process parameters for following experiments
