The invention relates to the technical field of metallurgy, in particular to a symmetric blank making method for producing a stainless steel composite plate through vacuum electron beam welding, which comprises the following steps of: selecting raw materials of a stainless steel plate, a carbon steel plate and an L-shaped steel billet; milling the carbon steel plate to obtain a carbon steel substrate; the stainless steel plates are stacked on the carbon steel base plate and subjected to vacuum seal welding, and a single-face composite blank is obtained; combining L-shaped steel billets; the stainless steel face of one single-face composite blank is placed upwards, the two L-shaped steel billets are placed to be combined into an outer frame shaped like a Chinese character'hui ', then the outer frame is coated with a separant, and finally the other single-face composite blank is stacked in the direction that the stainless steel face is downward, so that a to-be-welded stacked blank is formed; welding the stacke
