Abstract
Abstract
The process parameters of the Laser Metal Deposition technology in the production of simple components made of NiCuBSi type metal powder were verified in this paper. A laser head with a coaxial powder supply and argon gas was used in the production. The powder was welded to a S235J2G3 steel plate. The used parameters (heat input 0.25 kJ.mm−1) enabled the production of samples with a minimum porosity (1.2 %) and without the defects (cold joints, pores) between the weld layers.
