Abstract

The paper analyzes the influence of the new flux cored wire intended for cladding process by different sets of cladding parameters. Technological parameters of the cladding process such as welding speed, power source setting, the length of projecting portion of the electrode, thermal conductivity coefficient of aluminum for heating dissipation was analyzed. Description  of the influence of these parameters was made as a function of  the hardness distribution and structure in bead. The results of hardness distribution analysis allow to illustrate the nature of the impact of the examined input variables on parameters of developed surface. The most important parameters of the deposited hard layers here are the hardness distribution and the structure of bead. The cladding processes were conducted by Flux Cored Arc Welding (FCAW). As additional material for cladding material type Fe-Cr-C-with composite was used. To describe the properties of the layers visual test (VT), penetrant testing (PT), Vickers hardness, optical microscope (OM) and scanning electron microscope (SEM) were used. To describe the level of protection the surface against wear the test G65 was conducted.
