The invention provides automatic welding equipment for plateau area railway station house beam columns, and belongs to the technical field of medical welding equipment. A first motor in a moving assembly is fixed to a second mounting box, a first lead screw is fixed to the first motor, a moving block is in transmission connection with the first lead screw, and a moving table is fixed to the movingblock. A first supporting plate in a rotating assembly is fixed to the moving table, a second motor is fixed to the first supporting plate, a first rotating shaft is fixed to the second motor, and amounting rod is fixedly mounted on the first rotating shaft. A third supporting plate and a fourth supporting plate in a welding assembly are arranged on one side of the mounting rod, a third motor isfixed to the third supporting plate, a second rotating shaft is fixed to the third motor, an oxygen pump is fixed to the second rotating shaft, and a welding head is fixed to the oxygen pump. Throughthe devices, position movement and height adjustment of the welding equipment are achieved, angle adjustment of the welding head is achieved, the welding maneuverability and flexibility are improved,meanwhile, oxygen can be provided, and the welding efficiency and the welding quality are greatly improved.
