Method for bead welding repair of high manganese steel cast steel frog and steel rail

The invention discloses a method for bead welding repair of a high manganese steel cast steel frog and steel rail, and belongs to the technical field of welding. The method for bead welding repair of the high manganese steel cast steel frog and steel rail comprises the specific steps that quality judgment is carried out on the damaged portion of the high manganese steel cast steel frog and steel rail, machining before welding is carried out on the damaged portion of the high manganese steel cast steel frog and steel rail, over bead welding repair is carried out on the damaged portion of the high manganese steel cast steel frog and steel rail, polishing and forming are carried out on the high manganese steel cast steel frog and steel rail processed through bead welding repair, and quality inspection is carried out. The method for bead welding repair of the high manganese steel cast steel frog and steel rail has the advantages that preheating does not need to be carried out on the high manganese steel cast steel frog and steel rail before repair is carried out, heat treatment does not need to be carried out after welding is accomplished, implementation of the welding repair technology is easy, the cost is low, efficiency is high, labor intensity is low, quality is high after welding repair is accomplished, and performance is stable and reliable.
