    Application of high-strength steel in the Wire Arc Additive Manufacturing (WAAM) process
    (University of Žilina, 2024) Frátrik, Martin; Mičian, Miloš
    The work deals with the application of high-strength structural steel in the process of wire arc additive manufacturing (WAAM). In this work, layers are welded by the cold wire TIG method. The aim of the work is to analyse the effect of process parameters and layering on the resulting geometry and mechanical properties of the experimental welds. The results showed that the mechanical properties of the welds are dependent on the direction of loading as well as on the welding thermal cycle.

    Stratégie frézovania tenkostenných komponentov z ťažkoobrobiteľného materiálu
    (University of Žilina, 2023) Hrbál, Jakub; Vozár, Marek; Pätoprstý, Boris; Buranský, Ivan
    The paper deals with the issue of the influence of machining strategies and tool parameters on the quality of the machined surface of thin-walled parts made by WAAM technology. The current state of machining thin walled parts is complemented by utting tools in terms of materials, geometry, and tool wear. From the point of view of surface integrity, the roughness and flatness of machined thin-walled parts made of Inconel 718 nickel alloy material will be observed. The machining strategy and cutting tool geometry were designed by experimental machining. The results of the experiment are presented in the conclusion. Achieved experimental results are a contribution to the efforts to expand the knowledge on the topic of machining thin-walled parts.

    Using the cold metal transfer (CMT) method for wire arc additive manufacturing (WAAM) applications
    (University of Žilina, 2023) Frátrik, Martin; Mičian, Miloš
    This work deals with the possibilities of applying the MAG-CMT welding method for the purpose of wire arc additive manufacturing (WAAM). The WAAM method was operated using an industrial robot and welding device for MAG welding. The aim of the work was to compare three methods of laying layers in order to assess their mutual mixing. Cross-shaped perpendicular walls that were mutually connected as of the welded component were assessed. The geometry, macrostructure, and total operating costs of individual variants were evaluated. The result was the determination of the most accurate and most economical variant of laying layers.
