The article presents results of preliminary studies into obtaining a Ti–Cu–Ni braze composite for titanium and its alloys. Dimensions and properties of CuNi50 strip and titanium core wire were specified with regard to requirements for composite constituents’ weight proportions: 70%Ti, 15%Cu, 15%Ni. The study determines operating conditions of longitudinal welding of copper–nickel strip to obtain tubes with titanium core. Tests of processing composite Ti/CuNi50 through drawing allowed to define the process parameters necessary to obtain wire of required diameter. Initial tests in brazing properties of composite wire, conducted using flux-free arc brazing method, show proper Ti rod wetting by melting Ti/CuNi composite, which is confirmed by metallographic analysis.
