Cov khoom siv ntau tshaj plaws rau ntau hom vuam yog txhuas vuam hlau. Cov khoom siv no yog siv dav hauv cov txheej txheem thev naus laus zis ntawm kev siv tsis siv neeg thiab semi-automatic vuam. Kev txuas ntxiv ntawm cov txheej txheem, qhov ua tau zoo ntawm qhov ua tau zoo ntawm seam, kev tswj tus kheej ntawm tus nqi pub rau qhov chaw vuam - cov no yog nyob deb ntawm txhua qhov zoo uas txhuas hlau muaj.
Nws yog txoj cai paub zoo tias cov khoom ntawm cov khoom yuav tsum tau welded yuav tsum zoo ib yam nyob rau hauv muaj pes tsawg leeg rau cov muab tub lim siv. Cov xwm txheej no tseem ceeb tshwj xeeb, txij li qhov zoo ntawm qhov vuam, nws cov kav ntev thiab lub zog nyob ntawm nws.
Aluminium xaim feem ntau yog siv los vuam hlau ntawm cov khoom sib xws. Piv txwv li, rau tsis siv neeg thiab semi-automatic vuam cov ntaub ntawv xws li alloy, carbon los yog stainless hlau, raws li zoo raws li, tau kawg, aluminium-manganese alloys thiab txhuas qhov chaw. Gas vuam yog qhov zoo tshaj plaws rau kev tso cov xaim xaim ntawm lub seam.
Aluminium welding hlau yog ib txoj hlua hlau. Qhov no yog ib hom hloov tauib qho electrode uas yuav ua tau zoo hloov cov khoom tawg yooj yim thiab kim heev uas tuaj yeem siv tau thaum lub sijhawm ua haujlwm.
Aluminium hlau yog tsim los ntawm ib daim ntawv ntawm txhuas los ntawm kev kos duab thiab txiav mus rau hauv qhov ntev ntawm qhov yuav tsum tau ua. Cov neeg tsim khoom tau koom nrog kev siv ntau yam khoom zoo sib xws.
Nyob ntawm hom kev tsim khoom, txhuas hlau yuav muaj cov yam ntxwv sib txawv, cov kev cai sib txawv yuav raug yuam rau nws. Yog li ntawd, cov neeg tsim khoom yuav tsum tsim cov khoom tsim nyog. Txawm hais tias nws yog txhuas hlau ntawm ntau qhov ntev thiab ntu ntu, cov neeg thov yuav tsum txaus siab.
Aluminium yog ntau yam khoom siv uas muaj lub zog txaus thiab kev ntseeg siab, kev siv yooj yim thiab kev hloov pauv siab, muaj tus nqi qis thiab qhov hnyav.
Cov nram qab no hom ntawm txhuas hlau yog qhov txawv:
- Powder.
- Copper-plated.
- Stainless.
Txhua hom no muaj nws tus kheej daim ntawv thov nta. Piv txwv li, hom hmoov yog ib lub raj me me uas muaj cov hmoov txhuas sib xyaw ua ke. Qhov no tiv thaiv oxidation thiab slag tsim, thiab tseem yuav pab kom stabilize lub burning hluav taws xob arc. Stainless hlau yog siv los txuas chromium-muaj stainless hlau thiab npib tsib xee. Nyob rau hauv lem, tooj liab-plated yog sivrau vuam qhov chaw ua los ntawm alloyed cam khwb cia hlau thiab hlau, uas yuav pab tiv thaiv cov hlau spatter thiab tau zoo welds.
Kom tau txais cov khoom siv vuam zoo, tsis yog tsuas yog cov khoom siv muab tub lim xaiv yog qhov tseem ceeb, tab sis kuj tseem muaj lwm yam xws li qhov kub thiab txias ntawm thaj chaw vuam thiab qib ntawm qhov chaw tiav. Qhov no txhais tau hais tias lub melting kub ntawm cov khoom muab tub lim yuav tsum tsis txhob siab tshaj qhov melting kub ntawm qhov chaw yuav tsum tau welded, thaum lub hlau nto yuav tsum huv si thiab qhuav, tsis muaj oxides, nplai thiab kab ntawm cov xim.
