The invention belongs to the field of metal material processing and surface strengthening treatment, and provides a device and a method for repairing wheel and steel rail tread damage of a train, which are used for carrying out wheel and steel rail tread damage repairing and surface strengthening treatment, and are used for repairing fatigue cracks, hurts, spalling and scratches of wheel and steel rail treads through laser cladding. And in addition, the contact fatigue resistance and the friction resistance of the repaired positions of the wheel and the steel rail tread are improved through ultrasonic rolling treatment, so that the fatigue resistance of the repaired positions of the wheel and the steel rail tread is improved, safe operation of the wheel and the steel rail is guaranteed, and the service life of the wheel and the steel rail is prolonged. According to the method, wheel and steel rail tread damage defects are repaired through laser cladding, the wheel turning repair amount and the steel rail poli
