The invention discloses a method for processing a temperature thermocouple on the surface of a workpiece. Pure copper and copper-nickel alloy are respectively plated on the surface of the workpiece to be measured by a two-time electroplating technology, and the pure copper and the copper-nickel ally are only connected at a position point requiring temperature measurement. In the processing, the surface of the workpiece is subjected to polishing treatment, a layer of polytetrafluoroethene in molten state is uniformly coated on the surface of the workpiece, after the polytetrafluoroethene is solidified, a first groove is machined on the polytetrafluoroethene by a milling cutter to expose the surface of the workpiece, then a layer of pure copper is plated in the groove, and a layer of polytetrafluoroethene is coated on the workpiece again; a second groove symmetrical to the first groove is machined on the other corresponding position of the workpiece by the same method, the copper-nickel alloy is plated in the s
