Apparatus for gas-shielded arc welding

A thermionic heater cathode assembly of an electron-beam gun, comprising a disc cathode made of a highly-emissive material and disposed near a U-shaped ribbon filament with a thermionic portion and current-carrying sections arranged in parallel, wherein the ends of said ribbon filament sections to be connected to a holder are arranged in a plane normal to the ends of the same sections, adjoining the thermionic portion of said ribbon filament.

Thermionic heater cathode assembly of electron-beam gun

A thermionic heater cathode assembly for an electron-beam gun, comprising a disc cathode made of a highly-emissive material and disposed near a metal ribbon filament the thermionic portion whereof has a W shape, the distance between two apices of said thermionic portion being 0.6 to 0.8 of the disc cathode diameter and the depth of the valley between the apices constituting 0.5 to 0.6 of said diameter.
