ABSTRACT:
A method of producing sound metal castings, particularly of reactive metals, by striking an electrical arc in a gap defined by adjacent end faces of opposed elongate electrodes, wherein the electrodes are mounted for rotation about longitudinal axes that are parallel and offset with respect to each other, realizing substantially complete overlapping of the adjacent end faces during rotation of the electrodes to cause uniform depletion of same, and wherein the metal droplets derived at the gap are maintained in a fully molten condition until they have been cast into an adjacent mold.
