3. Thaum lub vuam ua haujlwm nyob rau hauv kev hnav, nws yog ib qho tsim nyog yuav tsum paub qhov txawv ntawm kev hnav los yog kev cuam tshuam, hnav intermetallic lossis abrasive hnav, hnav ntawm chav tsev kub lossis hnav ntawm qhov kub thiab txias, thiab lwm yam.. Yuav tsum tau txiav txim siab seb puas yuav ua hauj lwm hauv corrosive media. , nyob rau hauv thiaj li yuav xaiv qhov tsim nyog overlay vuam consumables.
4. Nyob rau hauv qhov tsis tshua muaj kub los yog kub kub vuam qhov chaw, yuav tsum tau xaiv los xyuas kom meej tias qhov kub tsis txias los yog kub siab mechanical zog ntawm cov khoom siv vuam.
Xav txog qhov nyuaj thiab cov yam ntxwv ntawm cov welded qhov chaw, welded sib koom hom, thiab lwm yam.
1. Cov duab tsis yooj yim lossis loj tuab ntawm cov welded qhov chaw, vim nws cov vuam hlau nyob rau hauv cov cua txias contraction ntawm sab hauv kev ntxhov siab generated los ntawm qhov loj, yooj yim los tsim cov kab nrib pleb.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau siv cov khoom siv vuam nrog cov kab nrib pleb zoo, xws li qis-hydrogen hom vuam pas nrig, siab toughness vuam pas nrig.
2. Rau qee cov pob qij txha nrog me me bevels, los yog cov pob qij txha nrog kev tswj xyuas nruj ntawm cov hauv paus nkag, cov khoom siv vuam vuam uas muaj qhov tob dua ntawm fusion lossis kev nkag mus yuav tsum tau siv.
3. Vim muaj kev txwv ntawm qee qhov vuam qhov nyuaj rau kev ntxuav, yuav tsum xav txog kev siv cov xeb, oxidation thiab cov tshuaj tiv thaiv roj tsis rhiab rau cov khoom siv vuam, xws li acid vuam pas nrig, thiaj li tsis ua kom tsis zoo xws li porosity.
Xav txog qhov chaw spatial ntawm weld
Qee cov khoom siv vuam siv tau tsuas yog tsim rau vuam hauv ib txoj haujlwm, lwm txoj haujlwm tsis tshua muaj txiaj ntsig thaum vuam, qee qhov vuam siv tau tuaj yeem vuam hauv ntau txoj haujlwm, cov yam ntxwv ntawm txoj haujlwm vuam yuav tsum tau txiav txim siab thaum xaiv.
Xav txog kev ua haujlwm vuam, kev ua haujlwm ib puag ncig
1. Tsis muaj DC vuam tshuab lub sijhawm, yuav tsum siv AC thiab DC dual-siv cov khoom siv vuam.
2. Qee cov hlau (xws li pearlite tshav kub-resistant steel) yuav tsum tau kho tom qab vuam kev nyuaj siab, tab sis los ntawm cov khoom siv los yog nws tus kheej cov txheej txheem txwv thiab tsis tuaj yeem nqa tawm, yuav tsum tau xaiv nrog lub hauv paus hlau tshuaj muaj pes tsawg leeg. Cov khoom siv vuam sib txawv (xws li austenitic stainless hlau vuam consumables), tuaj yeem raug zam los ntawm kev kho cua sov tom qab vuam.
3. Yuav tsum tau ua raws li qhov chaw tsim kho, xws li kev ua haujlwm hauv teb, qhov chaw ua haujlwm vuam, thiab lwm yam rau kev xaiv cov khoom siv vuam rational.
4. Nyob rau hauv qhov chaw uas ob qho tib si acidic thiab alkaline vuam electrodes siv tau, acidic welding electrodes yuav tsum tau siv kom deb li deb raws li qhov ua tau raws li qhov xav tau ntawm alkaline vuam electrodes rau kev ua haujlwm thiab kev npaj tsim.
Xav txog kev lag luam ntawm vuam
1. Sim siv cov khoom siv hluav taws xob siv hluav taws xob zoo, yog tias qhov kev ua tau zoo ntawm kev siv yog lav.
2. Cov khoom siv vuam sib txawv tuaj yeem siv rau thawj thiab theem nrab welds nrog cov kev ua tau zoo sib txawv, thiab tsis txhob ua raws li kev ua tiav ntawm cov khoom siv vuam unilaterally.
Xav txog welding efficiency
Rau cov qauv uas muaj cov khoom siv vuam loj, cov khoom siv vuam siv tau zoo yuav tsum tau siv kom deb li deb tau thaum muaj, xws li vuam hlau, hlau hmoov vuam pas nrig, zoo stainless hlau vuam pas nrig, thiab lwm yam.
