The electrode comprises an electrically conductive carbon electrode block with an electrically conductive metal member connected to it. At least one solid, conductive metal insert is at least partially received in the carbon electrode block with an interference fit such that the insert exerts a lateral force on the carbon electrode block. The insert provides an improved electrically conductive connection between the carbon electrode block and the reduced strength conductive metal member. the insert may provide a direct connection between the electrode block and the metal member, or the connection may be provided by means of a cast iron layer or other metal element provided between the electrode block and the metal member. The electrode assembly may comprise an anode or cathode.
