Formation of thickened elements on the edge parts of hollow cylindrical products, which serve as the elements of fuel lines of various power plants, can be applied to ensure a significant quality of their welding connection. The article deals with the formation of such thickening elements on tubes made of special non-ferrous alloys. Due to the mechanical features of these materials, these processes were investigated under narrow temperature and speed conditions causing short-term creep of the material. To analyze these operations, mathematical models have been created that describe power modes. Quantitative rules of the influence of the geometric parameters of the process on the pressure during the upsetting have been obtained. The materials obtained during the analysis can be used to create similar technologies.
