ABSTRACT:
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.
