Resistance vuam: Siv rau vuam nyias hlau qhov chaw. Lub workpiece yog clamped ntawm ob lub electrodes, thiab ib tug loj tam sim no yog siv rau yaj cov contact nto ntawm lub electrodes, yog li vuam yog tiav los ntawm cov cua sov ntawm lub workpiece tsis kam. Lub workpiece yog yooj yim deformation. Tsis kam vuam koom los ntawm ob sab, thaum laser vuam tsuas yog koom los ntawm ib sab. Cov electrodes siv nyob rau hauv kuj welding yuav tsum nquag tu kom tshem tawm oxides thiab hlau adhering rau lub workpiece. Laser welding ntawm nyias hlau ceg pob qij txha tsis koom nrog kev sib cuag nrog lub workpiece, thiab cov nqaj tuaj yeem nkag mus rau thaj chaw nyuaj mus cuag nrog cov pa vuam. Nws kuj muaj kev sib txuas ceev ceev.
Argon arc vuam: Siv cov khoom siv tsis yog - cov khoom siv hluav taws xob thiab cov roj tiv thaiv. Nws yog feem ntau siv los vuam nyias workpieces, tab sis qhov vuam ceev yog qeeb dua, thiab cov khoom cua sov yog ntau dua li laser vuam, ua rau nws yooj yim rau deformation.
Plasma arc welding: Zoo ib yam li argon arc vuam, tab sis nws lub teeb ua rau lub zog arc kom nce arc kub thiab lub zog ceev. Nws yog nrawm dua thiab muaj qhov tob tob dua li argon arc vuam, tab sis tsawg dua li laser vuam.
Electron beam welding: Siv lub nqaj nrawm nrawm, siab -zog- ntom electrons los cuam tshuam lub workpiece, ua kom muaj cua sov loj nyob rau hauv ib qho chaw me me ntawm qhov chaw ua haujlwm, tsim kom muaj "keyhole" cuam tshuam, yog li ua tiav kev sib sib zog nqus vuam. Qhov tsis zoo ntawm electron beam welding yog qhov xav tau rau lub tshuab nqus tsev siab kom tsis txhob muaj hluav taws xob tawg, cov khoom siv nyuaj, cov kev txwv ntawm qhov loj thiab cov duab ntawm lub tshuab nqus tsev vacuum chamber, thiab cov kev cai nruj heev rau kev sib dhos ua haujlwm zoo. Txawm hais tias tsis yog- lub tshuab nqus tsev electron beam welding tuaj yeem ua tau, kev tsom tsis zoo vim qhov tawg ntawm electron cuam tshuam rau cov txiaj ntsig. Electron beam vuam kuj nthuav tawm cov teeb meem ntawm kev sib nqus deflection thiab X-rays. Vim hais tias electrons raug them, lawv raug cuam tshuam los ntawm magnetic teb deflection, yog li yuav tsum tau demagnetization ntawm lub workpiece ua ntej welding. X-rays muaj zog tshwj xeeb nyob rau hauv kev kub siab, yuav tsum muaj kev tiv thaiv tus neeg teb xov tooj. Laser vuam, ntawm qhov tod tes, tsis xav tau lub tshuab nqus tsev los yog ua ntej- vuam demagnetization ntawm lub workpiece. Nws tuaj yeem ua tau nyob rau hauv cov huab cua thiab tsis muaj X- teeb meem kev tiv thaiv hluav taws xob, tso cai rau kev ua haujlwm hauv online hauv cov kab ntau lawm thiab vuam cov khoom sib nqus.
