Kev ua cov hlau tsis muaj hlau raws li cov khoom siv muaj ntau yam nta. Qhov no kuj siv tau rau vuam qhov chaw.
vuam stainless hlau tsis yog ib txoj haujlwm yooj yim. Nws xav kom tus neeg cog lus nruj me ntsis raws li cov txheej txheem thev naus laus zis. Qhov chaw sib txuas hlau yuav tsum raug tiv thaiv los ntawm qhov tsis zoo ntawm huab cua hauv huab cua. Los ntawm kev ua tiav cov xwm txheej no, peb yuav ua kom muaj kev ntseeg tau ntawm vuam.
Nyob rau hauv ntau txoj hauv kev, zoo stainless hlau vuam nyob ntawm qhov raug txiav ntawm cov npoo ntawm cov khoom yuav tsum tau welded thiab kev npaj ntawm cov electrodes.
Raws li qhov tshwm sim ntawm kev ua haujlwm kub ntawm qhov chaw, uas yog, lawv cov vuam, ib qho oxide zaj duab xis yog tsim, uas yuav tsum tau muab tshem tawm tom qab. Yeej, stainless hlau vuam yog ua los ntawm qhov tam sim no qhov chaw siv tungsten electrodes.
Stainless steel muaj chromium, uas, thaum kho nrog hluav taws, tsim cov tshuaj lom neeg ntawm cov pa roj carbon thiab chromium, uas cuam tshuam cov txheej txheem ntawm cov hlau thiab ua rau nws cov fragility.
Qhov tseeb, qhov no yog vim li cas yuam kev vuamstainless hlau nyob rau hauv ib puag ncig tiv thaiv roj thiab siv tshwj xeeb xaiv fluxes.
Welding Methods
Txhua hom vuam yog tsim los koom nrog cov hlau tsis huv. Muaj ib txoj cai tsis hais hauv qhov no. Yog hais tias cov khoom yuav tsum tau welded yog thicker tshaj li ib thiab ib nrab millimeters, arc vuam siv, uas yog nqa tawm manually nrog cov tsis-consumable electrodes ua los ntawm refractory tungsten. Cov txheej txheem no yuav tsum muaj nyob rau hauv ib puag ncig tiv thaiv ntawm ib qho ntawm inert gases. Cov pa roj no ruaj khov, tsis txhawb kev sib txuas thiab tsis tsim cov khoom siv tshuaj lom neeg nrog lwm cov ntaub ntawv. Thaum welding stainless hlau, inert gas tsis ua ke nrog cov hlau ntawm cov khoom yuav tsum tau welded.
A stainless hlau tank lossis nyias-walled stainless hlau kav tsis tuaj yeem welded los ntawm phau ntawv arc vuam.
Cov tswv cuab tsawg dua 1 hli tuab yog koom nrog cov khoom siv hluav taws xob hluav taws xob sib txuas hauv cov roj nruab nrab.
Cov khoom siv hlau nrog lub thickness hauv qab 0.8mm yog welded los ntawm hluav taws xob arc nrog hlau dav hlau hloov mus.
Ua ke nrog ob txoj hauv kev ntawm kev ua cov hlau tsis huv nrog cov hluav taws tau piav qhia saum toj no, kev siv ntau zaus, laser thiab lwm txoj kev vuam kuj tau siv dav.
Txoj kev sib txuas yog xaiv raws li qhov sib xyaw ntawm cov hlau thiab nws cov tuab.
Muaj ntau tus yam ntxwv ntawm stainless hlau vuam. Thiab yog hais tias lawv tsis raug coj mus rau hauv tus account, ces lub weld yuav tig tawm mus ua puas. Piv txwv li, tom qab vuam, corrosion tuaj yeem tsim nyob rau hauv qhov chaw ntawm lub seam, uas cov kws tshaj lij hu ua "riam corrosion". Thiab nrog ntev raug rau qhov kub thiab txias, lub seam yuav tawg.
Los ntawm kev xaiv cov ntaub ntawv muab tub lim thiab qhov ntev, "kub tawg" tuaj yeem tiv thaiv.
Thaum cov hlau tsis muaj hlau vuam tiav, cov seams tiav tiav nrog cov ntaub ntawv abrasive, ntxuav thiab sib tsoo lawv.
Tom qab ntawd kev kho cua sov tau ua tiav. Nyob rau hauv rooj plaub no, cov neeg thib peb cov khoom sib tov yog yaj, thiab chrome raug faib sib npaug thoob plaws hauv seam.
Txhawm rau ntxuav qhov vuam los ntawm cov av thiab cov quav hniav, siv cov tshuaj tua kab mob. Cov txheej txheem no kuj ua kom cov seam tsis xeb yav tom ntej.
