Raws li ib tug tho kev lag luam hauv lub Stainless hlau muaj welded yeeb nkab ntau lawm cov khoom siv kev lag luam, Hangao Tech kos cov lus xaus los ntawm cov neeg siv kev paub. Niaj hnub no, peb sib tham los ntawm cov txuj ci kev pom tias tsuas yog hloov cov lus pov hwm ntawm cov pa hluav taws xob, tsib qhov cuam tshuam tseem ceeb ntawm cov qauv vuam yuav raug tsim tawm:
(1) Txhim kho cov hlau Vuam Hlau Deposition Tus nqi piv nrog cov tsoos ntshiab carbon dioxide, cov roj sib xyaw ua ke feem ntau nqa ntau dua kev ua haujlwm ntau dua. Cov ntsiab lus Argon yuav tsum tau tshaj 85% kom ua tiav cov dav hlau hloov chaw. Ntawm chav kawm, txhawm rau txhim kho lub vuam hlau ouplete yuav xav tau kev xaiv ntawm vuam vuam qhov tsis haum. Cov nyhuv vuam feem ntau yog qhov tshwm sim ntawm ntau yam tsis muaj. Kev xaiv vuam tsis tsim nyog yuav txo cov vuam ua haujlwm thiab nce cov kev tshem tawm Slag tom qab vuam.
(2) tswj tau lub ntsej muag thiab txo qis ionization muaj peev xwm ntawm lub argon tom qab vuam slag tu txhim kho lub arc stability thiab sib xws li txo cov ncauj lus. Tsis ntev los no Welding Technology tswj lub ntsej muag ntawm carbon dioxide vuam. Nyob rau hauv tib qho kev mob, yog tias cov roj sib xyaw yog siv, nws tuaj yeem txo qis dua ntais thiab nthuav dav lub qhov rai vuam parameter.
(3) tswj lub vuam rooj sib tw tsim, txo cov pa roj carbon dioxide mending Lub argon mixed roj yog yooj yim los tswj lub vuam sib dhos thiab zam cov pov tseg ntawm vuam hlau.
(4) txhim kho ven hlau ceev. Los ntawm kev siv cov roj argon-nplua nuj, txawm tias lub vuam tam sim no nce, lub ntsej muag tseem ceeb tuaj yeem tswj tau zoo heev. Qhov zoo tau coj los ntawm qhov no yog qhov nce hauv vuam ceev, tshwj xeeb tshaj yog rau kev siv vuam, uas muaj kev txhim kho ntau dua.
(5) Tswj ntawm vuam fume. Nyob rau hauv tib lub vuam ua hauj lwm tsis muaj, cov sib cav sib ceg sib xyaw ua ke txo vuam fume piv rau cov pa roj carbon dioxide. Piv nrog kev nqis peev hauv cov khoom siv kho vajtse txhawm rau txhim kho kev lag luam vuam ib puag ncig, kev siv cov khoom siv argon-nplua nuj yog qhov kom zoo dua los txo cov kuab paug.
Rau tag nrho, nws tuaj yeem pom tias los ntawm kev xaiv vuam vuam thaiv kev npog cov roj av, vuam kom tau zoo, thiab vuam kev ua tau zoo.
Tam sim no, nyob hauv ntau qhov kev lag luam, Argon roj sib tov tau siv ntau, tab sis vim muaj ntau yam, tab sis kev lag luam hauv ntau 80% argon ar + 20% carbon dioxide. Nyob rau hauv ntau daim ntawv thov, cov kev tiv thaiv roj tsis ua tau zoo. Yog li ntawd, xaiv cov roj zoo tshaj yog qhov yooj yim los txhim kho kev tswj hwm cov khoom lag luam rau kev ua lag luam vuam rau tom ntej. Qhov tseem ceeb tshaj plaws rau kev xaiv cov kev tiv thaiv roj zoo tshaj plaws yog kom tau raws li qhov kev xaiv vuam tiag tiag. Ib qho ntxiv, cov roj ntws kom raug yog qhov ua ntej kom ntseeg tau tias vuam zoo, thiab ntau dhau lossis txo qis qis yuav tsis zoo rau vuam.
