Kuwotcherera kwa MIG kumagwiritsa ntchito waya wachitsulo m'malo mwa ma elekitirodi a tungsten mu tochi yowotcherera.Zina ndizofanana ndi kuwotcherera kwa TIG.Chifukwa chake, waya wowotcherera amasungunuka ndi arc ndikutumizidwa kudera lakuwotcherera.Wodzigudubuza wamagetsi amatumiza waya wowotcherera kuchokera ku spool kupita ku tochi yowotcherera malinga ndi zosowa zowotcherera.

Gwero la kutentha ndi DC arc, koma polarity ndi yosiyana ndi yomwe imagwiritsidwa ntchito powotcherera TIG.Gasi woteteza omwe amagwiritsidwa ntchito ndi wosiyana.1% mpweya uyenera kuwonjezeredwa ku argon kuti ukhale wokhazikika wa arc.

Palinso kusiyana kwa njira zoyambira, monga kutengerapo kwa jet, pulsating jet, kutengerapo kozungulira komanso kusamutsa kwafupipafupi.

Mawu osintha a Pulse MIG

Kuwotcherera kwa Pulse MIG ndi njira yowotcherera ya MIG yomwe imagwiritsa ntchito pulse current m'malo mwa DC yokhazikika.

Chifukwa chogwiritsa ntchito pulse current, arc of pulse MIG welding ndi mtundu wa pulse.Poyerekeza ndi kuwotcherera kwanthawi zonse (pulsating DC):

1. Zowonjezereka zosintha zosiyanasiyana zowotcherera;

Ngati wapakati wapano ndi wocheperako wocheperako I0 wakusintha kwa jakisoni, kusintha kwa jakisoni kumatha kupezekabe bola kugunda kwanthawi yayitali kumakhala kwakukulu kuposa I0.

2. Mphamvu za Arc zimatha kuyendetsedwa bwino komanso molondola;

Osati kukula kwa pulse kapena maziko apano omwe amatha kusintha, komanso nthawi yake imatha kusinthidwa mumagulu a 10-2 s.

3. Wabwino kumbuyo kuwotcherera luso la mbale woonda ndi udindo wonse.

Dziwe losungunula limasungunuka munthawi yapano, ndipo kuziziritsa kwa kristalo kumatha kupezeka munthawi yapano.Poyerekeza ndi kuwotcherera kosalekeza kwamakono, pafupifupi panopa (kulowetsa kutentha kwa weld) ndi kochepa pa malo olowera komweko.

Mawu osintha a MIG welding

Mosiyana ndi kuwotcherera kwa TIG, kuwotcherera kwa MIG (MAG) kumagwiritsa ntchito waya wowotcherera wa fusible ngati ma elekitirodi ndi kuwotcherera kwa arc pakati pa waya wowotcherera mosalekeza ndi weldment ngati gwero la kutentha kusungunula waya wowotcherera ndi chitsulo choyambira.Pa kuwotcherera ndondomeko, ndi kutchinga mpweya argon mosalekeza kutengerapo kuwotcherera m'dera kudzera kuwotcherera mfuti nozzle kuteteza arc, dziwe losungunuka ndi chapafupi m'munsi zitsulo ku zotsatira zoipa za mpweya ozungulira.Kusungunuka kosalekeza kwa waya wowotcherera kudzasamutsidwa ku dziwe lowotcherera ngati mawonekedwe a droplet, ndipo chitsulo chowotcherera chidzapangidwa pambuyo pa kusakanikirana ndi kusungunuka ndi chitsulo chosungunuka.

Kuwotcherera kwa MIG kumakhala ndi mawu osintha

⒈ monga kuwotcherera kwa TIG, imatha kuwotcherera pafupifupi zitsulo zonse, makamaka zoyenera kuwotcherera aluminium ndi aloyi, mkuwa ndi aloyi yamkuwa, chitsulo chosapanga dzimbiri ndi zida zina.Pali pafupifupi palibe makutidwe ndi okosijeni ndi kuyaka imfa mu kuwotcherera ndondomeko, pang'ono chabe evaporation imfa, ndi ndondomeko zitsulo ndi yosavuta.

2. Kuchuluka kwa ntchito

3. kuwotcherera kwa MIG kungakhale kugwirizana kwa DC reverse.Kuwotcherera aluminium, magnesium ndi zitsulo zina zimakhala ndi cathode atomization effect, zomwe zingathe kuchotsa filimu ya okusayidi ndikuwongolera ubwino wa kuwotcherera kwa olowa.

4. Electrode ya Tungsten sikugwiritsidwa ntchito, ndipo mtengo wake ndi wotsika kuposa wa TIG kuwotcherera;Ndizotheka kusintha kuwotcherera kwa TIG.

5. Pamene MIG kuwotcherera aluminiyamu ndi zitsulo zotayidwa aloyi, sub jet droplet kutengerapo angagwiritsidwe ntchito kupititsa patsogolo ubwino wa mfundo welded.

⒍ monga argon ndi mpweya wa inert ndipo sungagwirizane ndi chinthu chilichonse, imakhudzidwa ndi banga lamafuta ndi dzimbiri pamwamba pa waya wowotcherera ndi zitsulo zoyambira, zomwe zimakhala zosavuta kupanga pores.Waya wowotcherera ndi chogwirira ntchito ziyenera kutsukidwa mosamala musanawotchere.

3. Droplet transfer mu MIG kuwotcherera

Droplet kutengerapo amatanthauza njira yonse imene chitsulo chosungunula pa mapeto a kuwotcherera waya kapena elekitirodi amapanga m'malovu pansi pa zochita za arc kutentha, amene analekanitsidwa ndi mapeto a kuwotcherera waya ndi kusamutsidwa kwa kuwotcherera dziwe pansi pa zochita za mphamvu zosiyanasiyana.Zimagwirizana mwachindunji ndi kukhazikika kwa ndondomeko yowotcherera, mapangidwe a weld, kukula kwa splash ndi zina zotero.

3.1 mphamvu yomwe ikukhudza kusamutsa kwa madontho

Dontho lopangidwa ndi zitsulo zosungunuka kumapeto kwa waya wowotcherera limakhudzidwa ndi mphamvu zosiyanasiyana, ndipo zotsatira za mphamvu zosiyanasiyana pa kusintha kwa droplet ndizosiyana.

⒈ mphamvu yokoka: pamalo owotcherera, njira yokoka ndi yofanana ndi njira yosinthira madontho kuti apititse patsogolo kusintha;Pamwamba kuwotcherera malo, kulepheretsa droplet kusamutsa

2. Kuvutana kwapamtunda: sungani mphamvu yayikulu ya dontho kumapeto kwa waya wowotcherera pakuwotcherera.Kuchepa kwa waya wowotcherera, m'pamenenso madontho amatha kusintha mosavuta.

3. Mphamvu yamagetsi: mphamvu yopangidwa ndi mphamvu ya maginito ya kondakitala yokha imatchedwa mphamvu yamagetsi, ndipo chigawo chake cha axial nthawi zonse chimachokera ku gawo laling'ono kupita ku gawo lalikulu.Mu kuwotcherera kwa MIG, magetsi akamadutsa powotcherera madontho a elekitirodi wa waya, gawo lamtanda la kondakitala limasintha komanso komwe mphamvu yamagetsi imasinthira.Panthawi imodzimodziyo, kachulukidwe kakang'ono kameneka kameneka kamapangitsa kuti zitsulo zisungunuke kwambiri ndi kutulutsa mphamvu zambiri pazitsulo zazitsulo.Mphamvu yamagetsi yamagetsi pakusintha kwamadontho zimatengera mawonekedwe a arc.

4. Mphamvu yothamanga ya plasma: pansi pa kugunda kwa mphamvu yamagetsi, mphamvu ya hydrostatic yopangidwa ndi arc plasma molunjika ku arc axis imagwirizana mosagwirizana ndi gawo la gawo la arc column, ndiko kuti, imachepa pang'onopang'ono kuchokera kumapeto kwa kuwotcherera. waya pamwamba pa dziwe losungunuka, lomwe ndi chinthu chabwino cholimbikitsa kusintha kwa madontho.

5. Kuthamanga kwa malo

3.2 mawonekedwe osinthira madontho a kuwotcherera kwa MIG

Pa kuwotcherera kwa MIG ndi MAG, kusamutsa madontho kumatengera kusamutsa kwafupipafupi komanso kusamutsa ndege.Kuwotcherera kwa dera lalifupi kumagwiritsidwa ntchito powotcherera mbale zowonda kwambiri komanso kuwotcherera malo onse, ndipo kutengerapo kwa jeti kumagwiritsidwa ntchito powotcherera mopingasa matako ndi kuwotcherera fillet kwa mbale zapakati ndi wandiweyani.

Pa kuwotcherera kwa MIG, kulumikizana kwa DC reverse kumatengedwa.Chifukwa kugwirizana m'mbuyo kumatha kuzindikira kusintha kwa jet, ndipo ion yabwino imakhudza dontholo pamalumikizidwe abwino, zomwe zimapangitsa kuti pakhale kuthamanga kwakukulu kolepheretsa kusintha kwa madontho, kotero kuti kulumikizana kwabwino kumakhala kusintha kosasinthika.Kuwotcherera kwa MIG sikoyenera kusinthana ndi mawaya chifukwa kusungunuka kwa waya sikufanana pa theka lililonse.

Pamene MIG kuwotcherera zotayidwa ndi zotayidwa aloyi, chifukwa zotayidwa mosavuta oxidize, pofuna kuonetsetsa chitetezo zotsatira, arc kutalika pa kuwotcherera sangakhale yaitali kwambiri.Chifukwa chake, sitingathe kutengera njira yosinthira jet yokhala ndi arc yayikulu komanso yayitali.Ngati njira yosankhidwayo ndi yayikulu kuposa nthawi yovuta kwambiri ndipo kutalika kwa arc kumayendetsedwa pakati pa kusintha kwa jet ndi kusintha kwafupipafupi, kusintha kwa ndege kudzapangidwa.

Kuwotcherera kwa MIG kumagwiritsidwa ntchito kwambiri powotcherera zitsulo zotayidwa ndi aluminiyamu.[1]
