The invention discloses a heat-treatment-free monorail turnout weathering steel plate. The weathering steel plate comprises, by mass, 0.03-0.16% of C, 0.10-0.35% of Si, 0.70-1.60% of Mn, 0.20-0.40% ofCu, 0.35-0.70% of Cr, 0.25-0.60% of Ni, 0.01-0.08% of Alt, 0.01-0.05% of Nb, 0.005-0.020% of Ti and the balance iron and unavoidable impurities. A preparation method comprises the steps of smelting,refining, continuous casting, heating and rolling, and in the heating process, the complete solution temperature of Nb is calculated through a solid solution formula, and a casting slab is heated to the complete solution temperature of Nb or above. The weathering steel plate has excellent welding performance, and also has ultra-high strength, high toughness and high weather resistance; and heat treatment is not required in the production process, the production cost is reduced, and the production cycle is shortened.
