A filler cathode whose wall is constituted, at least in part, by a porous body made of refractory metal, such as tungsten, characterized in that it has a porous tungsten body of the desired size formed by molding and pre-melting at a temperature relatively low to ensure sufficient mechanical cohesion, this body being porous, possibly after a stage of shearing, slid over a part of the cathode structure to surround it with just fitting and form therewith a cavity, said cathode structure having a coefficient of thermal expansion higher than that of the porous body, the cathode having then been heated to a temperature higher by several hundredº C at the temperature at which the porous body has been pre-melted and higher than the temperature at which it must work the cathode.
