基板とし、その外周端部にのみクロム銅を嵌合して使用
した所謂複合電極が知られている。Known welding electrodes used in seam welding machines are often made of materials such as chromium copper, and recently, in order to reduce the amount of expensive chromium copper used, copper alloy is used as a substrate, and the outer peripheral edge A so-called composite electrode is known in which chromium copper is fitted only to the electrode.

電極を使用する場合においても電極軸を流れる冷却水に
よる間接冷却において溶接による電極発熱部近部を効率
よく冷却することができない。However, during seam welding, the welding electrode overheats considerably, so it is necessary to cool it.When using any of the electrodes mentioned above, indirect cooling by cooling water flowing through the electrode shaft is used to cool the area near the electrode heat generation part due to welding. It cannot be cooled efficiently.

果を増大ならしめるようにしたものである。Furthermore, the method of actively cooling the electrode by directly injecting water onto the outer surface of the electrode not only deteriorates the welding work environment but also has the disadvantage that the life of the electrode is relatively short. The present invention aims to improve this point, and specifically, the above-mentioned internal cooling means is provided in the joint area between the disk-shaped substrate and the outer ring plate that is fitted and integrated with the outer peripheral surface of the substrate. A water passage groove with a generally concave cross section is provided in the circumferential direction to communicate with a plurality of water passage holes drilled inside the substrate, so that the cooling water flowing through the electrode shaft reaches inside the heat generating area near the electrode tip. This is to increase the cooling effect.

い。Further, if the cooling water passing through the return path is drained to the outer surface of the electrode, it can also serve as external cooling. Further, as for the method of joining the substrate 2 and the outer ring plate 7, although electron beam welding is the most ideal method, the method is not necessarily limited to this, and ordinary methods such as solvent or brazing may be used.
