The invention discloses a spherical powder preparation method for high strength titanium alloy for material addition manufacturing, including the following steps: 1. Finishing the titanium alloy electrode rod; secondly, installing the refined titanium alloy electrode rod into the plasma rotary electrode atomization powder making equipment and vacuumizing; thirdly, the mixing gas is injected into the powder making equipment after vacuum extraction, and then the mixing gas is injected into the powder making equipment after vacuum extraction The powder was atomized by atomization, and the fourth was vacuum packaging to obtain the spherical powder of titanium alloy. The invention puts the titanium alloy electrode rod after finishing into the plasma rotary electrode atomization powder making equipment for atomization. By controlling the various process parameters of atomization, the preparation of titanium alloy spherical powder is realized, the refinement of spherical powder, the segregation of Fe element of spherical powder is prevented, the formation of "β spot" is avoided, and the specification of product quality stability is realized The method of mould production is simple and feasible, and the quality of titanium alloy spherical powder is stable.
