Method for hot-sizing welded integral vane disk by utilizing electron beam

The invention relates to a method for hot-sizing a welded integral vane disk by utilizing an electron beam, which belongs to the hot-sizing technical field. The method comprises the steps as follows: (1) in the preparation step before welding, the integral vane disk is processed through regional marking based on data variation characteristic according to a vane disk component deformation data table, then the vane disk is cleared, and combined technical equipment is adopted to enable the integral vane disk to achieve the sizing demand; (2) in the electron beam sizing step, the input of electron beam energy is controlled by electron beam sizing parameters according to the deflection range, so as to determine the range for depth of fusion; (3) in the position degree measurement step after sizing, position degree measurement is carried out on the integral vane disk which is processed through electron beam sizing, and the obtained result is recorded, compared and analyzed; and (4) in the heat treatment step for el
