The invention provides a method for adjusting a movement track during copper-chromium alloy contact surface laser modification. The method includes the steps that 100, the geometrical shape, size and after-modification performance requirements of a to-be-processed copper-chromium alloy contact, and parameters during laser modification are obtained; 200, by means of the information above, a simulation model is established through numerical calculation, and an optimized track running model suitable for current copper-chromium alloy contact laser modification is obtained; and 300, according to a running path given by the track running model and the preset laser processing parameters, the copper-chromium alloy contact is subjected to surface laser modification. By means of the method, during laser modification, the modification purpose of laser is achieved, meanwhile, the cooling and moving speed of a molten pool can be increased, the thermal stress can be effectively reduced, the change range of the thermal stress can be reduced, laser energy can uniformly act on the surface of the copper-chromium alloy contact, the copper roughness can be reduced, the flatness can be improved, and a uniform and high-property copper-chromium alloy contact surface fine grain layer can be formed.
