05/08/19Metal inert gas (MIG) vuam siv cov hlau siv hluav taws xob siv hluav taws xob thiab tiv thaiv cov pa roj, uas txuas mus ntxiv los ntawm rab phom vuam. Aluminium xav tau qee qhov kev hloov pauv tshwj xeeb rau cov neeg siv khoom uas tau siv rau vuam hlau. Nws yog cov hlau softer ntau dua li cov xov hlau yuav tsum loj dua. Aluminium tseem yog tus ua kom zoo dua ntawm cov cua sov, yog li vuam txhuas xav tau kev tswj hwm ntau dua ntawm cov khoom siv hluav taws xob thiab tus nqi pub ntawm cov hluav taws xob.
Cov kauj ruam
Txoj Kev 1 ntawm 2: Xaiv Cov Khoom Siv thiab Cov Khoom Siv
Kauj Ruam 1. Xaiv lub tshuab vuam siv lub zog ntau dua rau cov hlau tuab
Lub tshuab hluav taws xob 115-volt tuaj yeem ua haujlwm aluminium txog li yim ntawm ib nti tuab (3 hli) nrog qhov ua kom sov txaus, thiab lub tshuab 230-volt tuaj yeem txuas txhuas uas nce mus txog peb lub hlis twg ntawm tuab tuab (6 hli). Xav txog lub tshuab nrog cov zis ntau dua 200 amps yog tias koj yuav siv cov txhuas txhuas txhua hnub.
Kauj Ruam 2. Xaiv cov roj thaiv kom raug
Aluminium xav tau kev tiv thaiv roj ntawm cov ntshiab argon sib piv nrog cov hlau, uas ib txwm siv kev sib xyaw ntawm argon thiab carbon dioxide (CO2). Qhov no yuav tsum tsis muaj qhov hoses tshiab, txawm hais tias koj yuav xav tau hloov cov cai uas tau tsim tshwj xeeb rau CO2.
Kauj Ruam 3. Siv cov khoom siv hluav taws xob txhuas
Electrode tuab yog tshwj xeeb tshaj yog tseem ceeb nrog txhuas thiab muaj qhov nqaim heev los xav txog. Cov xaim me dua yog qhov nyuaj rau noj, thaum cov tuab tuab xav tau ntau dua tam sim no kom yaj. Cov electrodes rau vuam txhuas yuav tsum yog.035 ntawm ib txoj kab uas hla (tsawg dua 1 hli). Ib qho kev xaiv zoo tshaj plaws yog 4043 txhuas. Ib qho nyuaj hlau zoo li 5356 txhuas yooj yim rau pub, tab sis yuav xav tau ntau dua tam sim no.
Txoj Kev 2 ntawm 2: Siv Cov Txheej Txheem Zoo
Kauj Ruam 1. Pub cov electrodes nrog cov khoom siv txhuas
Cov khoom siv no muaj muag lag luam thiab yuav tso cai rau koj pub cov hlau xaim softer nrog cov yam ntxwv hauv qab no:
- Qhov loj dua ntawm cov lus qhia tiv tauj. Aluminium nthuav ntau dua li hlau raws li nws tau rhaub. Qhov no txhais tau tias cov lus qhia tiv tauj yuav xav tau qhov loj dua qhov uas siv rau cov hlau hlau ntawm qhov loj me. Txawm li cas los xij, lub qhov yuav tsum tseem me me txaus los muab kev sib txuas hluav taws xob zoo.
- U-shaped drive rolls. Aluminium feeders yuav tsum siv cov ntawv yob uas yuav tsis txhuam cov hlau txhuas. Cov lus qhia nkag thiab qhov hluav taws xob rau cov khoom noj no yuav tsum tsis txhob txhuam cov hlau xaim softer. Hauv kev sib piv, cov khoom siv hlau siv V-shaped drive rolls, uas tau tsim tshwj xeeb los txiav plaub hau.
- Cov kab uas tsis yog xim hlau, uas yuav txuas ntxiv txo qhov kev sib txhuam ntawm cov hlau thaum nws dhau los ntawm tus pub mis.
Kauj Ruam 2. Khaws rab phom xaim kom ncaj li sai tau kom cov xaim hluav taws xob noj kom raug
Cov xaim hluav taws xob tau yooj yim dua rau kinks vim txwv kev pub mis.
Lub tswv yim
- Qhov feem ntau weldable aluminium alloys kuj zoo li cov hlau tsis muaj zog tshaj plaws. Ntau yam aluminium alloy yog yooj yim tsis tuaj yeem txuas tau.
- Siv kev kho cua sov tom qab lub weld tau ua los txhim kho lub zog ntawm cov khoom siv kho cua sov.
- Aluminium weld yuav tsis tshua muaj zog li cov khoom siv hauv paus.
Lus ceeb toom
- Hnav khaub ncaws uas npog tag nrho koj txhais caj npab thiab txhais ceg thaum vuam, suav nrog hnab looj tes. Cov nplaim taws thiab cov pa taws yog qhov phom sij tas li.
- Ib txwm hnav lub ntsej muag phaj thaum vuam. Koj yuav tsum tsis txhob saib ncaj qha ntawm lub arc, txawm tias thaum hnav lub ntsej muag phaj.
