Abstract
A contact arrangement for a graphite electric arc-electrode employs a contact spud composed of a metal having a high melting point and a soldering layer disposed between the contact spud and graphite electrode. The soldering layer contains at least one carbide forming metal. In one embodiment of the invention, a carbide-forming metal layer is disposed between the graphite electric arc-electrode and the soldering layer. In a preferred form of the method of making the arrangement, the soldering layer and the carbide-forming metal layer are plasma-sprayed or steamed onto the surface to be connected.
