<p>An electrode joint in which two electrodes are joined by a threaded (12) nipple received in threaded frusto-conical sockets formed in respective end portions of the two electrodes; and in which one or each socket and/or the nipple portion received therein is provided with a friable thread segment (16) formed by thickening the non-loading long flank of the threaded segment and reducing the thickness of the load bearing short flank of the thread segment so that the thread segment spaces the remaining threads of the parts concerned uniformly during assembly and can fracture under heat stress into the relief space provided between the reduced short flank and the cooperating thread of the other portion. <IMAGE></p> |
