The invention discloses a preparation method of a texture nickel-tungsten composite base band and belongs to the technical field of synthesis of texture metal base bands for reinforcing high-temperature coating superconductors. Inner and outer layers of initial billets are prepared through a smelting process; a nickel-tungsten composite billet is obtained through a draw forming mode; the efficiency is high; the cost is low; inner and outer layers of elements are subjected to interdiffusion through diffusion annealing to form metallurgical bonding at an interface after drawing, and therefore the interface bonding intensity of the composite billet is higher.
