Zusammenfassung:The use of exothermic addition (EA) for charge in flux-cored wire is a promising way to improve technological characteristics of welded joints. The mathematical models to determine the charge density and the fill factor, which depend on the EA content, the ratio of graphite to EA oxidizer (CuO/C) and the ratio of the oxidizer to the aluminum powder in the composition of the EA (CuO/Al) were built. The investigated fusion modes depend mostly on such parameters: EA = 26–28 mass%, CuO/C = 4.0–4.5 and CuO/Al = 4.50–5.25.
