Technological process of laser cladding with laser beam and powder jet delivered coaxially into processing zone is investigated in this paper. Mutual influence of focused laser beam and gas-powder stream on parameters of clad layer (dimensions, porosity etc.). Two research methods were used for investigation of gas-powder jet focusing with nozzles of different configurations: numerical simulation with further experimental verification and experiment planning technique. Statistically significant influence technological parameters (mutual position of laser beam waist, gas-powder jet profile, workpiece etc.) on the productivity (dimensions) and quality (number of pores) of the clad layer.
Keywords: laser technology, laser cladding, simulation, optimization.
