The present invention relates to a welding member for recycling railway wheels and a method for recycling railway wheels using the same. Specifically, the present invention provides a method for recycling railway wheels, the method comprising the steps of: welding worn railway wheels using a first welding member and overlaying the railway wheels (step 1); and welding the overlaid railway wheels using a second welding member to form a surface hardened layer (step 2), wherein the first welding member is composed of 0.05-0.15wt% of carbon, 0.2-1.0wt% of silicon, 1.0-2.0wt% of manganese, 0.6-1.2wt% of chromium, unavoidable impurities, and the remainder iron; and the second welding member is composed of 0.1-0.25wt% of carbon, 0.2-1.0wt% of silicon, 1.0-2.0wt% of manganese, 1.4-2.0wt% of chromium, 0.2-1.0wt% of molybdenum, unavoidable impurities, and the remainder iron, and wherein the railway wheels are wheels of one kind selected from the group consisting of trains, passenger cars, urban railway ...
