Because the surface of the kettle body is a curved surface, the irregular shape of the overlapping surface of the snake-shaped spout and the kettle body is easy to generate local deformation due to high temperature in the welding process, and the product quality is influenced. In the prior art, welding of a kettle mouth and a kettle body of a kettle is generally completed by simultaneously performing spot welding through a plurality of welding guns.

Corresponding to the welding guns, a plurality of second electrodes are required to be arranged inside the kettle body. In the prior art, a conductive block made of copper or other conductive metals is generally arranged in a kettle body, and a plurality of boss columns are processed on the conductive block corresponding to the welding part of a kettle mouth and the kettle body to be used as second electrodes. In the spot welding process, the electrode bar and the second electrode extrude the kettle body and the kettle nozzle, after a plurality of welding operations, the convex column is lost along with the welding, when the gap between the second motor and the kettle body is overlarge due to abrasion, the convex column needs to be repaired or the conductive block needs to be replaced, because the convex columns and the conductive block are integrated, when one convex column needs to be repaired, the conductive block needs to be integrally processed, and then the inner surface of the kettle body needs to be aligned again; the repair takes much time, and the alignment is frequently checked, which results in low production efficiency.
