ABSTRACT:
A successively joinable carbon electrode for use in gouging or blasting metallic articles comprises a copper coated electrode body having one end formed into a coaxial connecting projection and the other end formed with a coaxial tapered socket for receiving the connecting projection of another carbon electrode of identical construction. The connecting projection consists of a tapered stem portion adjacent the electrode body and a cylindrical portion on one side of the stem portion opposite to the electrode body such that the projection of one carbon electrode can tightly be fitted into the socket of another carbon electrode with the copper layer on such one carbon electrode electrically connected to the copper layer on such another carbon electrode.
