The utility model relates to the technical field of transmission shafts, and discloses a projection welding electrode structure for welding a variable-diameter transmission shaft, which comprises a main body, a moving head is slidably connected in the main body, a first hydraulic rod is arranged in the moving head, and a driving end of the first hydraulic rod is fixedly connected with an upper electrode. An operation table is fixedly connected to the inner bottom of the moving head, a lower electrode is fixedly connected to the upper surface of the operation table, first tangent planes are formed in the lower electrode and the upper electrode, two second tangent planes which are in bilateral symmetry are also formed in the lower electrode and the upper electrode, and a welding assembly is arranged on the outer wall of the moving head. According to the projection welding electrode, when the binding face is machined, the two balance piece outer arc radius tangent structures are machined, the two arc matching ap
