Ikibazo gikunze kugaragara mubikorwa byiterambere ni: Ese Electron Beam Welding (EBW) ikenera pompe vacuum? Igisubizo kigufi ni yego yumvikana, mubenshi mubibazo. Pompo vacuum ntabwo ari ibikoresho gusa ahubwo ni umutima wimikorere ya EBW isanzwe, itanga ubushobozi bwihariye.
Intangiriro ya EBW ikubiyemo kubyara umurongo wa electroni yihuta cyane kugirango ushonge kandi uhuze ibikoresho. Iyi nzira irumva bidasanzwe molekile ya gaze. Mugihe kitari icyuho, izo molekile zagongana na electron, bigatuma urumuri rutatana, gutakaza ingufu, na defocus. Igisubizo cyaba ari ubugari bwagutse, budasobanutse, kandi budakora neza, bugatsinda burundu intego ya EBW yerekana neza no kwinjira cyane. Byongeye kandi, cathode yimbunda ya electron, isohora electron, ikora mubushyuhe bwo hejuru cyane kandi ishobora guhita igahita ihita iyo ihuye numwuka.
Kubwibyo, High-Vacuum EBW, uburyo bwiganje cyane, busaba ibidukikije bisukuye bidasanzwe, mubisanzwe hagati ya 10⁻² na 10⁻⁴ Pa.Kubigeraho bisaba sisitemu yo kuvoma ibyiciro byinshi. Pompe ikabije ibanza gukuraho igice kinini cyikirere, igakurikirwa na pompe-vacuum nyinshi, nka pompe ikwirakwizwa cyangwa turbomolecular pompe, ikora ibintu byiza bikenewe kugirango ikorwe neza. Ibi bitanga umwanda udafite umwanda, ubunyangamugayo buhanitse bwo gusudira, bigatuma biba ingenzi mu kirere, mu buvuzi, no mu gice cya kabiri.
Itandukaniro rizwi nka Medium cyangwa Soft-Vacuum EBW ikora kumuvuduko mwinshi (hafi 1-10 Pa). Nubwo igabanya cyane igihe cyo kumanura umusaruro kugirango ikore neza, iracyasaba rwose pompe vacuum kugirango ibungabunge ibidukikije bigenzurwa, bifite umuvuduko muke kugirango wirinde gutatana cyane na okiside.
Ibidasanzwe bigaragara ni Non-Vacuum EBW, aho gusudira bikorerwa mu kirere. Ariko, ibi birayobya. Mugihe icyumba cyakazi cyakuweho, imbunda ya elegitoronike ubwayo iracyabungabungwa mu cyuho kinini. Igiti noneho giteganijwe binyuze murukurikirane rwumuvuduko utandukanye wumuyaga. Ubu buryo bubabazwa cyane no gukwirakwiza ibiti kandi bisaba gukingira X-ray gukingira, kugabanya imikoreshereze yabyo yihariye.
Mu gusoza, ubufatanye hagati ya beam ya electron na pompe vacuum nicyo gisobanura ubwo buhanga bukomeye. Kugirango ugere ku bwiza buhebuje kandi busobanutse EBW izwiho, pompe vacuum ntabwo ari amahitamo-ni ngombwa byingenzi.
