The paper analyzes the influence of the quality of the new flux cored wire intended for cladding process by one set cladding parameters such as welding speed, thermal conductivity coefficient of aluminum, power source setting, the length of projecting portion of the electrode, wire speed and speed of oscillation on the hardness distribution and structure in bead. The results of hardness distribution analysis allows to illustrate the nature of the impact of the examined input variables on parameters of generated surface. The most important parameters here are the hardness distribution and structure of bead. The cladding process was conducted by Flux Cored Arc Welding (FCAW). As additional material for cladding Fe-Cr-C-Nb was used. To describe the properties of the layers Vickers hardness, optical microscope (OM) and scanning electron microscope (SEM) were used.
