Galimoto yopangidwa ndi zida za aluminiyamu yamafakitale imakhala ndi ubwino wopepuka, kukana dzimbiri, mawonekedwe abwino a flatness ndi zinthu zobwezerezedwanso, motero amayamikiridwa ndi makampani oyendera mizinda ndi madipatimenti oyendetsa njanji padziko lonse lapansi.
Magalimoto amtundu wa aluminiyumu yamafakitale ali ndi ntchito zosasinthika popanga njanji yothamanga kwambiri, chifukwa chake kuthamanga kwake kumathamanga kwambiri. Pakalipano, magalimoto opangidwa ndi aluminiyumu ya mafakitale okhala ndi aluminiyumu yonse akhala akugwiritsidwa ntchito kwambiri popanga ma EMU ndi magalimoto apamtunda wamtunda wamtunda, makamaka zitsulo za EMU zothamanga kwambiri zimasinthidwa ndi matupi amtundu wa aluminiyumu wa mafakitale.
Mu kupanga mafakitale zotayidwa mbiri galimoto matupi, chifukwa kwambiri ntchito mbiri splicing mu dongosolo, ndi mfundo ndi yaitali ndi wokhazikika, amene ndi yabwino kukwaniritsidwa kwa ntchito basi, kotero zosiyanasiyana wanzeru kuwotcherera matekinoloje ambiri ntchito mu makampani izi.

Kuwotcherera Automatic kumakhala kofunikira pakuwotcherera kwa matupi amtundu wamagalimoto a aluminiyamu. Iwo wakhala ambiri anazindikira ndi kuwotcherera makampani ubwino wake khola kuwotcherera khalidwe ndi dzuwa mkulu kupanga. Tsopano popeza kufunikira kwa kuwotcherera kwanzeru kukuchulukirachulukira, akukhulupirira kuti ukadaulo wazowotcherera udzakula kwambiri posachedwa.
Mawonekedwe amtundu wamagalimoto amtundu wa aluminiyamu wamagalimoto othamanga kwambiri a EMU
Magalimoto amtundu wa aluminiyumu yamagalimoto a EMU othamanga kwambiri amagawidwa m'magulu apakatikati a mbiri ya aluminiyamu yamafakitale ndi gulu lamoto lamtundu wa aluminiyamu yamafakitale. Magalimoto apakatikati a mbiri ya aluminiyamu yamafakitale amapangidwa makamaka ndi magawo anayi: underframe, khoma lam'mbali, denga, ndi khoma lomaliza. Mutu wamagalimoto amtundu wa aluminiyumu wamakampani amapangidwa makamaka ndi magawo asanu: pansi, khoma lakumbali, denga, khoma lomaliza ndi kutsogolo.

Kuwotcherera kwa mbiri ya aluminiyumu yamagalimoto agalimoto mu ma EMU othamanga nthawi zambiri amagawidwa kukhala kuwotcherera kwa magawo akulu, magawo ang'onoang'ono ndi msonkhano waukulu. Kuwotcherera kwa magawo akuluakulu kumatanthawuza kuwotcherera kwa mapanelo a denga, mapanelo a denga lathyathyathya, pansi, madenga ndi makoma am'mbali; Kuwotcherera kwa tizigawo tating'onoting'ono nthawi zambiri kumatanthawuza kuwotcherera kwa makoma akumapeto, m'mbali mwake, makoma ogawa, mbale za siketi ndi mipando ya coupler. The kuwotcherera basi wa msonkhano waukulu zambiri amatanthauza kuwotcherera basi wa mfundo pakati pa khoma ndi denga, ndi khoma mbali ndi underframe. Kuyika ndalama pazida zazikulu zowotcherera ndi chinthu chofunikira popanga matupi amtundu wa aluminiyamu wamagalimoto.
Poyamba kupanga mbiri ya aluminiyamu yamafakitale a EMU othamanga kwambiri, loboti yowotcherera ya IGM ya waya imodzi idagwiritsidwa ntchito powotcherera. Ndikukula kwa mphamvu zopanga za EMU komanso kusintha kwamachitidwe, loboti yowotcherera ya waya imodzi ya IGM yasiyidwa chifukwa chakuchepa kwawo. Mpaka pano, zigawo zonse zazikulu zamagalimoto a aluminiyamu othamanga kwambiri a EMU amawotcherera ndi mawaya apawiri a IGM.
Kugwiritsidwa ntchito kwakukulu kwaukadaulo wowotcherera wa MIG popanga matupi othamanga kwambiri a EMU mafakitale aluminiyamu yamagalimoto kwathandizira kwambiri luso laukadaulo wazowotcherera komanso kuthekera kopanga mzere wopangira, motero kuwonetsetsa kuti matupi agalimoto amtundu wa aluminiyamu amapangidwa. EMU yothamanga kwambiri, yathandizira kwambiri pantchito yopanga njanji zothamanga kwambiri.

Friction stir welding (FSW) ndi njira yolumikizirana yolimba. Cholumikizira chowotcherera chimakhala ndi zida zabwino zamakina komanso mawonekedwe ang'onoang'ono owotcherera. Sichiyenera kuwonjezera mpweya wotchinga ndi waya wowotcherera, ndipo palibe kusungunuka, fumbi, spatter ndi kuwala kwa arc panthawi yowotcherera, yomwe ndi teknoloji yatsopano yogwirizana ndi chilengedwe. Patangotha zaka zochepa kuchokera pomwe ukadaulo wa FSW unayamba, kupita patsogolo kwakukulu kwachitika pamakina ake owotcherera, zida zogwirira ntchito, zida zowotcherera ndi ntchito zamainjiniya.
