Lub vuam hlau puas muaj txee lub neej?
Tsawg-hydrogen vuam siv tau yog ob xyoos.
Graphite vuam cov ntaub ntawv thiab lwm yam ntaub ntawv vuam yog ib xyoos.
Cov vuam vov, fluxes thiab flux-cored vuam vuam uas nws cov sij hawm dhau lub sij hawm dhau lub sij hawm kws kho mob yuav tsum raug tshuaj xyuas dua los ntawm cov chaw haujlwm muaj feem ua ntej yuav raug tso tawm rau siv. Hauv txoj ntsiab cai, kev tshuaj xyuas tshiab feem ntau tsom rau kev ntsuam xyuas seb cov khoom siv vuam puas muaj kev puas ntsoog uas yuav cuam tshuam rau lub vuam kev ua tau zoo, thiab feem ntau txwv rau qhov zoo li thiab cov txheej txheem kev ua tau zoo. Txawm li cas los xij, thaum muaj kev ua xyem xyav txog qhov ua tau zoo ntawm cov khoom vuam, cov khoom kuaj xyuas tsim nyog tuaj yeem txuas ntxiv.
Lub sijhawm tau teem tseg tuaj yeem txiav txim siab raws li cov qauv hauv qab no txij li hnub ua haujlwm:
a) Lub sijhawm pom zoo ntawm vuam cov khoom pov thawj zoo daim ntawv pov thawj lossis phau ntawv tuav;
b) Cov cuab yeej ua kua hlau thiab cov ntaub ntawv siv tshuab ua kom tsis tshua muaj vuam ntev nrog kev tiv thaiv zoo ya raws yog ob xyoos;
c) Ib xyoos rau graphite vuam cov ntaub ntawv thiab lwm yam ntaub ntawv vuam.
Qhov no yog qhov yuav tsum tau ua hauv JB / T 3223-1996" Vuam Khoom Tswj Xyuas Kev Tswj Xyuas Zoo" ;.
Lub txee lub neej ntawm stainless hlau electrodes
Lub txee lub neej ntawm stainless hlau vuam pas nrig yog ob xyoos, thiab nws yuav tsum tsis txhob ntxooj.
Electrodes stainless hlau yuav muab faib ua chromium stainless hlau electrodes thiab chromium nickel stainless hlau electrodes. Ntawm ob yam hluav taws xob no, cov uas tau raws li lub teb chaws tus qauv raug ntsuas raws li lub teb chaws tus qauv GB / T983-1995. Chromium stainless hlau muaj qee yam corrosion tsis kam (oxidizing acid, organic acid, cavitation) kub thiab corrosion kuj. Feem ntau xaiv raws li cov cuab yeej siv rau cov chaw nres tsheb fais fab, tshuaj chemical, roj av thiab lwm yam khoom siv. Txawm li cas los xij, thev taus ntawm chromium stainless hlau feem ntau tsis zoo. Xim yuav tsum them rau cov txheej txheem welding, kev kho cua sov thiab qhov kev xaiv ntawm cov vuam vuam uas haum. Chromium-npib tsib xee stainless hlau electrodes tau zoo corrosion thiab oxidation tsis kam, thiab yog siv dav hauv tshuaj lom neeg, chiv, roj av, thiab kho tshuab kev lag luam. Txhawm rau tiv thaiv intergranular xeb vim tias muaj cua sov, lub vuam tam sim no yuav tsum tsis txhob loj heev, uas yog kwv yees li 20% tsawg dua li ntawm cov hlau carbon electrodes, lub arc yuav tsum tsis txhob ntev dhau, thiab interlayer txias yuav tsum nrawm, thiab a nqaim weld hlaws zoo dua.
Puas yog Lincoln hlau muaj lub neej txee?
Yog tias nws yog cov khoom siv hlau khov, nws zoo li tsis muaj ib yam tseem ceeb hauv lub neej txee.
Yog tias cov khoom siv xov hlau khov kho tau tsim nyog, nws yuav tsum tsis txhob xeb thiab xeb, thiab nws qhov kev ua haujlwm yuav tsis cuam tshuam yog tias nws muab tso rau ib lossis ob xyoos;
Rau flux-cored vuam hlau, nws tseem yuav tsum tau them sai sai rau kev ya raws thiab kev tiv thaiv xeb. Rau lub sijhawm ntev cia, tab sis tsis muaj xeb ntawm cov tsos, lub vuam hlau uas tsis xau tus neeg sawv cev tuaj yeem siv ib txwm siv. Yog tias koj tsis paub tseeb, koj tuaj yeem siv cov hlau txuas hlau coj los ua kev sim. Kuaj qhov hlau ntsuas ua tau zoo.
