ABSTRACT:
Apparatus for electric arc graining the surface of a traveling electrically conductive workpiece, the surface having a substantial area. The graining is effected by a continuous loop electrode having an elongated main body portion and an elongated continuous loop tip edge projecting laterally from a general plane of the main body portion for establishing an arc between the tip edge and the workpiece surface. The arc is moved about the continuous electrode tip by elongated magnetic means located in close proximity to the electrode, the magnetic means including a continuous loop pole member spaced outwardly of and concentric with the continuous loop tip edge. A second pole member of a polarity opposite the outer pole member is located in the general center of the closed loop tip edge.
