The invention discloses a special welding wire for automatically welding a main steam pipe in a nuclear power station. The welding wire comprises the following chemical components: 0.05 to 0.1 wt% of C, 0.7 to 1.0 wt% of Si, 1 to 1.5 wt% of Mn, less than or equal to 0.02 wt% of P, less than or equal to 0.02 wt% of S, less than or equal to 0.15 wt% of Ni, 1.00 to 1.50 wt% of Cr, less than or equal to 0.15 wt% of Mo, and less than or equal to 0.4 wt% of Cu. Compared with the prior art, the chemical compositions of the deposited metal of special welding wire for automatically welding a main steam pipe in a nuclear power station are similar to those of SA335 P11 main steam pipe, the mechanical properties of the welding wire are better than or equal to a present CHW-40CNH welding wire, the anti-FAC performance of a weld joint of an SA335 P11 main steam pipe welded by the welding wire is greatly raised, the quality of the weld joint of the main steam pipe in the nuclear power station can be ensured during operation, so the weld wire is significant for safety operation of a nuclear power unit.
