description The invention discloses a preparation method for large titanium-nickel alloy ingots. According to the method, a mold cavity is used, and a detachable auxiliary support is placed in the mold cavity and is used for dividing the inner space of the mold cavity into N grids which are horizontally arranged; 3-12.7 mm sponge titanium and square blocky electrolytic nickel are used as raw materials and are proportioned according to the composition proportion of titanium-nickel alloy to be prepared so as to obtain N parts of mixed raw materials; and each part of the mixed raw materials is poured into the corresponding grid; the auxiliary support is taken out from the mold cavity; electrode blocks for smelting the titanium-nickel alloy is formed by one-time vertical pressing; and the above steps are repeated to obtain a plurality of electrode blocks for smelting the titanium-nickel alloy, the electrode blocks are assembled and welded to form consumable electrodes, and then the consumable electrodes undergo vacuum smelti
