description: The given work is devoted to the study of the process of non-vacuum electron beam deposition with copper alloy wire by developing a mathematical model of the process. The research set the following goals: - development of a model for filler wire heating and melting; - development of a model of the heat transfer process in the melt pool; - calculation of wall preheating temperature; - development of a model of the surface formation of the deposited layer; - determine the relationship between the process parameters and the surface formation of the deposited layers; - calculate the cross-section shape of the deposited wall. In the course of the work, a theoretical study of the direct deposition process was carried out. The result of it allows to determine the relationship between the process parameters and the surface formation of the deposited layers with reasonable accuracy. The temperature field in the filler wire and the deposited product was determined by analytically solving the quasi-stationary and non-stationary heat conduction equations for a moving and distributed heat source. The equation of the liquid phase equilibrium in the gravity field is used to analyze the mechanism of the formation of the bead surface profile. The proposed method allows determining the shape of the wall surface of the product with satisfactory accuracy.
