The invention relates to a mounting method for an air duct external flange of a rail vehicle. The air duct external flange comprises an external flange cylinder and an external flange edge, wherein the external flange cylinder is formed by arranging four wing plates in a surrounding manner; the bottom ends of the left and right wing plates of the external flange cylinder are flush with that of the external flange edge. The mounting method comprises the following steps: putting the pre-welded air duct external flange on the vehicle; moving the air duct external flange to an appointed position to ensure that the left and right wing plates of the external flange cylinder together with the external flange edge fall on a flat top plate of the vehicle while the four wing plates of the external flange cylinder are propped against a middle end top plate of the vehicle; welding the bottom ends of the left and right wing plates of the external flange cylinder and the bottom end of the external flange edge with the flat top plate of the vehicle through spot welding, and welding the four wing plates of the external flange cylinder with the middle end top plate of the vehicle through spot welding, so as to fix the air duct external flange; welding the four wing plates of the external flange cylinder with the middle end top plate of the vehicle through full welding. The air duct external flange mounted according to the mounting method has the advantages that the mounting requirement of an air conditioner external air duct and the sealing requirement of a steel structure of a vehicle body can be met simultaneously; the structure is simple; the technology is easy to realize.
