Makina owotcherera ndodo za aluminiyamu amadziwika chifukwa cha luso lawo lopanga ma welds amphamvu komanso odalirika. Komabe, vuto limodzi lodziwika bwino lomwe lingakhudze ubwino wa ma welds awa ndi chikasu cha malo owotcherera. Yellow iyi, yomwe nthawi zambiri imayamba chifukwa cha okosijeni, imatha kusokoneza kukhulupirika kwa ma welds. M'nkhaniyi, tiwona njira zothetsera ndi kupewa chikasu cha malo owotcherera pamakina a aluminiyamu ndodo.
1. Kukonzekera Zinthu Moyenera
Kupewa chikasu kumayamba ndi kukonzekera bwino zinthu. Onetsetsani kuti ndodo za aluminiyamu zowotcherera ndi zoyera komanso zopanda zowononga monga dothi, mafuta, kapena oxidation. Tsukani bwino zinthu za ndodozo pogwiritsa ntchito njira zoyenera zoyeretsera, monga kutsuka kapena kuyeretsa mankhwala, kuti muchotse zonyansa zilizonse zomwe zingasinthe mtundu.
2. Mumlengalenga Wolamulidwa
Njira imodzi yabwino yopewera chikasu panthawi yowotcherera ndiyo kupanga malo olamulira kuzungulira malo owotcherera. Izi zitha kutheka pogwiritsa ntchito mpweya wa inert, monga argon, kuteteza malo owotcherera ku mpweya wa mumlengalenga. Kuteteza gasi kwa inert kumalepheretsa oxidation ndikuthandizira kusunga mtundu wachilengedwe wa aluminiyumu.
3. Kutenthetsa
Kutenthetsa ndodo za aluminiyamu musanayambe kuwotcherera kungathandizenso kuchepetsa chikasu. Powonjezera kutentha kwa ndodozo, kutentha kwa kutentha kumachepetsa kufalikira ndi kutsika komwe kungayambitse kutsekemera kwa okosijeni. Amalimbikitsa kuwotcherera kosalala, kuchepetsa mwayi wachikasu.
4. Zoyenera Zowotcherera Zoyenera
Zowotcherera, kuphatikiza pakali pano, kupanikizika, ndi nthawi yowotcherera, zimathandizira kwambiri kupewa chikasu. Kugwiritsa ntchito magawo olondola a ndodo za aluminiyamu zomwe zikuwotcherera kumapangitsa kuti kutentha kuzikhala bwino komanso kumachepetsa chiopsezo cha okosijeni. Onani malingaliro a wopanga pazigawo zoyenera zowotcherera.
5. Pambuyo pa Weld Kuyeretsa ndi Chithandizo
Pambuyo kuwotcherera, ndikofunikira kuyeretsa ndi kukonza zowotcherera mwachangu. Chotsani zotsalira zotsalira kapena zonyansa pogwiritsa ntchito njira zoyenera zoyeretsera. Kenaka, ganizirani kugwiritsa ntchito chithandizo cha post-weld, monga njira yoyeretsera ya aluminiyamu kapena zokutira zotetezera, kuti muteteze kuwonjezereka kwa okosijeni ndi chikasu.
6. Njira Zodzitetezera
Gwiritsani ntchito njira zodzitchinjiriza kuti muteteze zowotcherera ku mpweya wozungulira panthawi yomwe mukuwotcherera. Izi zingaphatikizepo kugwiritsa ntchito makatani owotcherera kapena zishango kuti apange chotchinga chomwe chimachepetsa kukhudzana ndi mpweya. Kusunga malo owotcherera opanda ma drafts kungathandizenso kuti malo owotcherera azikhala okhazikika.
7. Kusamalira Nthawi Zonse
Yang'anani nthawi zonse ndikusunga makina owotcherera, kuphatikiza maelekitirodi ndi zida zowotcherera mutu. Kuvala kulikonse kapena kuwonongeka kwa zigawozi kungayambitse kuwotcherera kosagwirizana ndi kuchuluka kwa okosijeni. Kuthana ndi mavutowa mwachangu kungathandize kupewa chikasu.
Pomaliza, kuthana ndi kupewa chikasu cha kuwotcherera pamwamba pazitsulo zowotcherera zotayira ndodo za aluminiyamu kumafuna kuphatikiza koyenera kwa zinthu, mlengalenga woyendetsedwa, kutentha, kutentha, ndi kutsatira magawo oyenera kuwotcherera. Kuonjezera apo, kuyeretsa pambuyo pa weld ndi chithandizo, pamodzi ndi njira zodzitetezera ndi kukonza nthawi zonse, ndizofunikira kwambiri kuti mukhalebe okhulupirika ndi maonekedwe a welds. Potsatira izi, mutha kuwonetsetsa kuti kuwotcherera ndodo ya aluminiyamu kumatulutsa ma weld apamwamba kwambiri osasintha mtundu.
