Nyob rau hauv peb lub hnub nyoog high-tech, refractory, tshav kub-resistant, anti-corrosion thiab hluav taws xob-resistant cov ntaub ntawv tau dhau los ua ntau thiab ntau, uas yuav tsum tau tshwj xeeb cov tswv yim rau vuam. Xws li electron beam welding, nyob rau hauv uas qhov kub ntawm lub active ua hauj lwm cheeb tsam mus txog ib txhiab lub sij hawm siab tshaj nrog ib txwm txoj kev. Ultra-siab kub hauv hom vuam no ua tiav vim photons lossis electrons txav hauv lub tshuab nqus tsev ntawm qhov ceev ntawm li 165,000 km / s. Thaum foob pob hlau ntawm qhov ceev tsis txaus ntseeg, lub zog kinetic ntawm cov khoom siv hluav taws xob hloov mus rau hauv cov cua sov, uas ua rau cov hlau melts.
Electron-beam welding yog nqa tawm hauv chav tshwj xeeb, los ntawm huab cua yav dhau los tau tso tawm. Qhov chaw tsis muaj cua yog tsim kom cov electrons tsis txhob nkim lawv lub zog ntawm ionization ntawm cov roj sib tov thiab kom tau txais cov hlau zoo tagnrho yam tsis muaj kev cuam tshuam txawv teb chaws. Lub teeb cathode beam, raws li lub tshuab nqus tsev no hu ua, yog nruab nrog lub lens tshwj xeeb sib nqus tsim los tsim cov khoom siv hluav taws xob ncaj qha thiab tswj tau zoo. Nws kuj muaj qhov chaw thau khoom rau kev pub khoom noj kom raug welded.
Electron beam welding yog ua tiav nrog qhov tsis tshua muaj hluav taws xob hloov tam sim no. Nws ntws los ntawm cov ntsiab lus tshwj xeeb (lens), qhov twg cathode thiab anode nyob, thiab, yog li, ib qho hluav taws xob ntws nrog cov yam ntxwv tshwj xeeb raug tsim. Hauv kev teeb tsa hluav taws xob qis, tungsten lossis tantalum kauj yog siv los ua cathode. Thiab yog tias cov txheej txheem thev naus laus zis thiab cov khoom ntiag tug ntawm cov ntaub ntawv raug welded xav tau ntau lub zog, tom qab ntawd cathodes ua los ntawm cermet lossis lanthanum hexaboride, uas muaj peev xwm ua kom muaj hluav taws xob dawb, twb tau siv.
Nyob ntawm tus qauv tsim ntawm lub installation, electron beam welding tuaj yeem ua los ntawm kev txav cov khoom siv welded perpendicular mus rau lub nqaj ruaj khov, lossis rov ua dua, cov nqaj tuaj yeem txav mus rau qhov chaw ruaj. Tsis tas li ntawd, kev tsim ntawm qee qhov kev teeb tsa muab rau cov khoom siv tshwj xeeb deflecting, uas muab ntau lub sijhawm rau kev tau txais cov duab kos.
hom vuam no yog siv dav hauv vuam cov hlau muaj zog hlau thiab titanium-based alloys, nrog rau cov hlau xws li molybdenum, tantalum, niobium,tungsten, zirconium, beryllium. Rau precision machining thiab vuam ntawm ntau yam micro qhov chaw. Nws yog siv rau hauv kev lag luam xws li foob pob hluav taws kev tshawb fawb, nuclear zog, precision instrumentation, microelectronics, thiab ntau lwm yam.
Nrog rau cov cuab yeej hluav taws xob hluav taws xob, laser vuam kuj tseem dav. Cov cuab yeej siv rau hom vuam no yog lub tshuab hluav taws xob kho qhov muag, uas yog ib qho khoom siv niaj hnub ntawm cov hluav taws xob sib txuas. Qhov tseem ceeb sib txawv ntawm laser vuam thiab electron beam txoj kev yog tias nws tsis xav tau lub tshuab nqus tsev vacuum. Cov txheej txheem vuam siv tshuab laser yog ua nyob rau hauv ib puag ncig huab cua lossis nyob rau hauv cov xwm txheej ntawm saturation ntawm lub chamber nrog tshwj xeeb tiv thaiv gases - carbon dioxide, argon thiab helium.
