Connection between the sections of a graphite electrode in whose faces a socket is sunk to accommodate a threaded nipple. The socket base has a rotation-symmetrical recess whose principal sections are defined by a second or higher order curves and go over into the socket generating surface continuously differentiably. The annular stress active in the connection zone is reduced in particular by the recess.

Electrode connection

Connections between sections having thread sockets at the end face of carbon or graphite electrode by a double-conical threaded nipple screwed into the sockets in which the cone halves of the nipple are different in height.
