Electrode rod welding structure and manufacturing method

Abstract

The application discloses an electrode rod welding structure and a manufacturing method, and belongs to the technical field of welding structure of electrode rod. The electrode rod welding structure comprises a ceramic electrode base, an electrode assembly and a threaded sleeve. The ceramic electrode base is provided with a threaded hole, and the bottom of the threaded hole is provided with a first assembly part. One end of the electrode assembly is provided with a second assembly part. The electrode assembly is installed in the threaded hole, and the second assembly part is installed in cooperation with the first assembly part. The outer circumferential side of the electrode assembly is formed with a first step part and a welding wire groove. The first step part is located between the second assembly part and the welding wire groove. The welding wire groove is used for placing a welding wire. The threaded sleeve is in a hollow structure. The inner side wall of the threaded sleeve is formed with a second step part matched with the first step part. The threaded sleeve is sleeved on the outer circumferential side of the electrode assembly, and the threaded sleeve is threadedly connected with the threaded hole, so that the electrode assembly is locked in the threaded hole. The application reduces the risk of cracking of the ceramic electrode base, has good sealing air tightness, and is not easy to be de-welded.
