First step towards carburasation of thoriated tungsten filaments is making the filament.
We started with a mold of graphite, in which we put two Ti-5Al-2.5Sn wires and some lead-glass powder.
We heated the graphite with an induction heater, the coil is air-cooled with a compressor.
Next, we spot-welded the thoriated tungsten wires to the Ti-5Al-2.5Sn wires.
Video of the induction heating and the spotwelding:
