Aluminiyamu yoyera ndi chitsulo chofewa komanso chotulutsa bwino.Kwa zomangamanga zambiri, mphamvu zake ndizochepa.Kuti muwonjezere mphamvu ya aluminiyumu, ma alloying amayenera kuwonjezeredwa.Copper, silicon, manganese, magnesium, ndi zinc amagwiritsidwa ntchito ngati chinthu chachikulu kuti azitha kulimbitsa mphamvu yosungunuka.Aluminiyamu ndi zitsulo zotayidwa zimagwiritsidwa ntchito kwambiri m'mafakitale ambiri.
Kuwotcherera kwa aluminiyamu ndi zitsulo zotayidwa kumakhala kovuta kwambiri kuposa chitsulo chochepa cha carbon.Makhalidwe ake kuwotcherera ndi osiyana ndi otsika mpweya zitsulo.Zochita zenizeni ndi izi:
1. Soferality wa welded kulumikiza makina ntchito, utachepa kukana dzimbiri.
2. Mankhwalawa ndi amphamvu kwambiri, ndipo pamwamba pake amapangidwa mosavuta.
3. Wamphamvu matenthedwe madutsidwe, ndipo n'zosavuta chifukwa insoluble chodabwitsa pa kuwotcherera.
4. Zowonongeka zotsatizana monga pores, ming'alu, kuluma m'mphepete, slag ndi kupanga weld.
5. Large mzere kukulitsa coefficient (pafupifupi 2 nthawi otsika-carbon zitsulo), amene sachedwa kupiringizika ndi mapindikidwe pa kuwotcherera.
6. The matenthedwe madutsidwe ndi lalikulu (pafupifupi 5 nthawi otsika-carbon zitsulo).Pa liwiro lomwelo kuwotcherera, kulowetsa kwamafuta kumakhala kokulirapo 2 mpaka 4 kuposa chitsulo chowotcherera.
Aluminiyamu aloyi ndi welded ndi TIG kapena GMAW.
1. Aluminiyamu aloyi tig kuwotcherera
Ngati mukufuna kupeza kuwotcherera kwapamwamba kwambiri, kuwotcherera kwa Tig nthawi zambiri ndiko kusankha koyamba.Njira yoyenera kwambiri ndiyo kusinthanitsa kuwotcherera kwa TIG ndi kuwotcherera kwa AC pulse TIG.Pali zabwino zingapo:
1. Pamene kuwotcherera, makhalidwe cathode atomization akhoza kuchotsedwa palokha.
2. Fomu yolumikizira ilibe malire, pamwamba ndi yosalala komanso yabwino kuumba.
3. Malo owotcherera a mpweya kuti aziziziritsa olowa kuziziritsa pansi ndi kukonza bungwe ndi ntchito.
Chifukwa chake, njirayi ndiyabwino kwambiri pamakampani apamwamba kwambiri komanso ofunikira kwambiri zakuthambo.Inde, kuipa kwake kulinso koonekeratu.kuwotcherera dzuwa ndi otsika, ndipo si oyenera kupanga lalikulu-mwachangu mkulu.
1. Aluminiyamu aloyi GMAW kuwotcherera
Kuwotcherera kwa Gmaw kwalowa pang'onopang'ono m'miyoyo yathu.Kulumikizana kwa reverse kwa DC nthawi zambiri kumagwiritsidwa ntchito pakuwotcherera, ndipo kuwotcherera kwa pulse kumatha kugwiritsidwanso ntchito.Poyerekeza ndi kuwotcherera kwa TIG, kuwotcherera kwa GMAW kuli ndi izi:
1. Pafupifupi palibe zoyaka za okosijeni panthawi yowotcherera, ndipo njirayo ndiyosavuta.
2. Kuchuluka kwa ntchito.
3. Osatengera mitengo ya tungsten, yotsika mtengo.
Mukawotchera mu GMAW, samalani izi:
1. Muyenera kugwiritsa ntchito payipi ya silika yopangidwa ndi pulasitiki, ndipo payipi yachitsulo singagwiritsidwe ntchito.
2. Waya wowotcherera wa aluminiyumu ndi wofewa ndipo kutumiza kwa waya kumakhala kovutirapo.Muyenera kusankha gudumu loperekera waya lofanana ndi U-shaped groove.
3. Gwiritsani ntchito kamwa yoyenera yamkati yamkati.
4. Osagawana magawo ndi kuwotcherera zitsulo kuti mupewe kuipitsa.
GMA-A5356 imagwiritsa ntchito zotsatira patsamba la kasitomala
Deta iyi imagawana ndi ogwiritsa ntchito omwe akuyenda kapena atsala pang'ono kuwotcherera, zomwe zimatilola kupita patsogolo pamsewu wowotcherera a aluminium alloy.
Zomwe zimaperekedwa ndi kampani yathu ndi izi:
Mbiri ya TIG MIG
GTA-A4043 GMA-A4043
GTA-A5183 GMA-A5183
