Application of high-strength titanium alloys in modern aircraft construction poses new challenges every year both to the developers of such alloys and to specialists in the field of joining materials. Wire Arc Additive Manufacturing (WAAM) is a highly promising technology, which allows manufacturing complex-shaped large-sized parts from high added value materials. This technology is part of additive manufacturing processes, which uses metal wires as filler materials and the arc - as the energy source. The paper shows the application of the developed experimental metal-cored wire based on a promising local highstrength titanium alloy T120 in multilayer argon-arc surfacing. The joint microstructure, its microhardness and mechanical properties were studied. 10 Ref., 1 Tabl., 4 Fig.
Keywords: high-strength titanium alloys, WAAM, TIG, metal-cored wire
