Hauv tag nrho cov txheej txheem ntawm cov hlau tsis xeb ua cov txheej txheem, txhua yam ntawm cov vuam txoj kev siv tau. Cov sawv daws muaj xws li siv tes ua ob-raj cua sov tube arc vuam, argon arc vuam tshuab, siab tsis siv neeg arc vuam, carbon dioxide tiv thaiv vuam, thiab tsis kub-vau plasma vuam.
1. Kev siv tes ua tooj vuam ntawm cov hlau tsis huv: Cov cuab yeej siv los tsim kev cai yog qhov tshwj xeeb dav thiab siv vuam ntau, thiab nws tseem yog qhov tsim kho thiab siv tau yooj yim vuam txoj kev. Lub sijhawm ntev ntawm arc tuaj yeem kho tau los ntawm phau ntawv ua haujlwm los ntawm tus neeg teb xov tooj, thiab kev hloov kho tau ua raws li qhov sib txawv ntawm qhov nruab nrab ntawm stainless hlau electrode thiab cov khoom ua haujlwm uas yuav tsum tau welded, thiab qhov ntev ntawm arc tuaj yeem kho tau raws li rau qhov loj me ntawm cov kis.
2. Yas roj tiv thaiv vuam tsoo: hauv no hom kev ua haujlwm, arc tsim lub tungsten arc vuam hlau thiab cov khoom lag luam hlau. Lub vias vias uas siv rau hom vuam thaiv no yog roj av argon, uas xa los ntawm kev siv lub tshuab ua haujlwm tsis siv neeg thiab khoom siv. Cov khoom hluav taws xob nws tus kheej tsis energized.
3. Nws yog xim hlau cov khoom siv roj thaiv cov vuam: nws yog hom yam ntawm lub vapor tsis siv neeg tuaj yeem tiv thaiv arc vuam. Hauv tag nrho cov txheej txheem ntawm kev thov cov qauv no, arc yog nyob hauv qab ntawm cov txheej txheem tiv thaiv pa roj hmab lub raj xa khoom kom coj tawm kev tiv thaiv kev nqus ntawm cov vuam txuas thiab cov hlau stainless phaj cov khoom ua haujlwm. Lub vuam viav vias txau los ntawm cov khoom siv vuam tshuab vuam tshuab yog vuam hlau, uas yaj mus ua kua hlau stainless phaj hauv qab cov kab hlau.
Txoj kev sib txawv vuam tuaj yeem muaj qhov sib txawv ntawm cov txiaj ntsig rau cov khoom sib txawv stainless hlau ua cov khoom lag luam. Hauv tag nrho cov txheej txheem ntawm kev vuam tsim thiab ua lossis yuav tsum raug xaiv raws li cov khoom siv cov khoom thiab cov yam ntxwv ntawm kev tsim khoom thiab ua, cov khoom tsim nyog yuav tsum tau xaiv. Vuam, yog li peb tuaj yeem ua tiav cov txiaj ntsig vuam qhov tseeb.
