Kuwotcherera kwa MIG, monga njira ina iliyonse, kumayeserera kukonzanso luso lanu. Kwa omwe angoyamba kumene, kupanga chidziwitso choyambirira kumatha kutengera ntchito yanu yowotcherera ya MIG kupita pamlingo wina. Kapena ngati mwawotcherera kwakanthawi, sizimapweteka kukhala ndi chotsitsimutsa. Ganizirani mafunso omwe amafunsidwa pafupipafupi, limodzi ndi mayankho awo, ngati malangizo akuwotcherera kuti akuwongolereni.
1. Kodi ndiyenera kugwiritsa ntchito roll yanji, ndipo ndimayimitsa bwanji?
Kukula kwa waya wowotcherera ndi mtundu wake kumatsimikizira mpukutu woyendetsa kuti upeze chakudya chosalala, chokhazikika pawaya. Pali zisankho zitatu zodziwika bwino: V-knurled, U-groove ndi V-groove.
Gwirizanitsani mawaya a gasi kapena odziteteza okha okhala ndi V-knurled drive rolls. Mawaya owotcherera awa ndi ofewa chifukwa cha kapangidwe kake ka tubula; mano pa masikono pagalimoto agwire waya ndi kukankhira izo kupyolera wodyetsa pagalimoto. Gwiritsani ntchito mipukutu ya U-groove podyetsa waya wowotcherera wa aluminiyamu. Maonekedwe a ma drive rolls awa amalepheretsa kuwononga waya wofewa. V-groove drive rolls ndiye chisankho chabwino kwambiri pamawaya olimba.
Kuti mukhazikitse kuthamanga kwa drive roll, choyamba masulani ma drive rolls. Pang'onopang'ono yonjezerani kupanikizika uku mukudyetsa waya m'manja mwanu. Pitirizani mpaka kugwedezeka kutha kupitirira theka la waya. Panthawiyi, sungani mfutiyo mowongoka momwe mungathere kuti mupewe kinking chingwe, zomwe zingayambitse kusadya bwino kwa waya.
Kutsatira njira zabwino kwambiri zokhudzana ndi waya wowotcherera, ma rolls oyendetsa ndi kutchingira gasi zitha kuthandizira kuwonetsetsa zotsatira zabwino pakuwotcherera kwa MIG.
2. Kodi ndimapeza bwanji zotsatira zabwino kuchokera ku waya wanga wowotcherera wa MIG?
Mawaya owotcherera a MIG amasiyana malinga ndi mawonekedwe awo komanso magawo awowotcherera. Nthawi zonse yang'anani kuchuluka kwa mawaya kapena pepala la data kuti mudziwe kuchuluka kwa ma amperage, ma voliyumu ndi mawaya akuthamanga komwe wopanga zitsulo amalimbikitsa. Mapepala apadera nthawi zambiri amatumizidwa ndi waya wowotcherera, kapena mutha kuwatsitsa kuchokera patsamba la opanga zitsulo. Mapepalawa amaperekanso zofunikira zotetezera gasi, komanso mtunda wolumikizana ndi ntchito (CTWD) ndi kukulitsa waya wowotcherera kapena malingaliro a stickout.
Stickout ndiyofunikira kwambiri kuti mupeze zotsatira zabwino. Kumamatira kwa nthawi yayitali kumapangitsa kuti pakhale chowotcherera chozizira kwambiri, kugwetsa mpweya ndikuchepetsa kulowa m'malo olumikizana. Chomata chachifupi nthawi zambiri chimakhala chokhazikika komanso cholowera pang'onopang'ono. Monga lamulo la chala chachikulu, utali wopendekera wabwino kwambiri ndi ufupi kwambiri womwe umaloledwa kugwiritsa ntchito.
Kusungirako bwino kwa waya wowotcherera ndi kusamalira ndikofunikiranso kuti pakhale zotsatira zabwino zowotcherera za MIG. Sungani spool pamalo owuma, chifukwa chinyezi chikhoza kuwononga waya ndikupangitsa kuti hydrogen iphwanyike. Gwiritsani ntchito magolovesi pogwira waya kuti muteteze ku chinyezi kapena dothi kuchokera m'manja mwanu. Ngati mawaya ali pawaya, koma osagwiritsidwa ntchito, phimbani spool kapena chotsani ndikuyika mu thumba la pulasitiki loyera.
3. Kodi ndigwiritse ntchito njira yanji yolumikizirana?
Njira yolumikizirana, kapena malo olumikizirana nawo mkati mwa mphuno yowotcherera ya MIG, zimatengera njira yowotcherera, waya wowotcherera, kugwiritsa ntchito ndi kutchingira mpweya womwe mukugwiritsa ntchito. Nthawi zambiri, pamene kuchuluka kwapano kukuchulukirachulukira, nsonga yolumikizana nayo iyeneranso kuwonjezeka. Nazi malingaliro ena.
Kupuma kwa 1/8- kapena 1/4-inch kumagwira ntchito bwino pakuwotcherera pama amps opitilira 200 popopera kapena kuwotcherera kwapakali pano, mukamagwiritsa ntchito waya wachitsulo komanso mpweya wotchingira wolemera argon. Mutha kugwiritsa ntchito waya womata 1/2 mpaka 3/4 mainchesi muzochitika izi.
Sungani nsonga yanu yolumikizirana ndi mphuno mukamawotchera zosakwana 200 amps mumayendedwe afupiafupi kapena otsika apano. Chomata chawaya cha 1/4- mpaka 1/2-inch chikulimbikitsidwa. Pa 1/4-inch stick out in short circuit, makamaka, imakupatsani mwayi wowotcherera pa zipangizo zowonda kwambiri zomwe zili ndi chiopsezo chochepa cha kuwotcha kapena kumenyana.
Mukawotcherera zolumikizira zolimba komanso zosakwana 200 amps, mutha kuwonjezera nsonga yolumikizana ndi 1/8 inchi kuchokera pamphuno ndikugwiritsa ntchito chomata cha 1/4-inch. Kukonzekera uku kumapangitsa kuti munthu athe kupeza mwayi wambiri wolumikizana ndi zovuta kuzipeza, ndipo zimagwira ntchito bwino pamayendedwe afupipafupi kapena otsika kwambiri.
Kumbukirani, kupuma koyenera ndikofunika kwambiri kuti muchepetse mwayi wa porosity, kusalowa mokwanira ndi kuwotcha komanso kuchepetsa spatter.
Malo abwino olumikizirana nsonga yopuma amasiyanasiyana malinga ndi ntchito. Lamulo lokhazikika: Pamene mvula ikuwonjezeka, kupuma kuyeneranso kuwonjezeka.
4. Ndi mpweya wotani wotetezera womwe uli wabwino kwambiri pa waya wanga wowotcherera wa MIG?
Gasi wotchinga womwe mumasankha umadalira waya ndi ntchito. CO2 imapereka malowedwe abwino mukawotchera zinthu zokhuthala, ndipo mutha kuyigwiritsa ntchito pazinthu zocheperako chifukwa imakonda kuzizira, zomwe zimachepetsa chiopsezo choyaka. Kuti mulowetse bwino kwambiri komanso kuti mukhale ndi zokolola zambiri, gwiritsani ntchito 75% argon/25% CO2 kusakaniza kwa gasi. Kuphatikiza uku kumapanganso spatter yocheperako kuposa CO2 kotero kuti pamakhala kuyeretsa kochepa pambuyo pa weld.
Gwiritsani ntchito 100 peresenti ya CO2 yotchinga mpweya kapena 75 peresenti ya CO2/25 peresenti ya argon kusakaniza pamodzi ndi waya wa carbon steel solid. Waya wowotcherera wa aluminiyamu amafuna mpweya wotchingira wa argon, pomwe waya wachitsulo chosapanga dzimbiri umagwira ntchito bwino ndi kuphatikiza kwa helium, argon ndi CO2. Nthawi zonse tchulani chikalata chawaya kuti mudziwe zomwe mungakonde.
5. Kodi njira yabwino yothanirana ndi thabwa langa la weld ndi iti?
Pamalo onse, ndi bwino kuti waya wowotcherera uwoloke kutsogolo kwa thambi la weld. Ngati mukuwotcherera (yoyima, yopingasa kapena pamwamba), kusunga thambi la weld kukhala laling'ono kumapereka mphamvu yabwino kwambiri. Gwiritsaninso ntchito waya wocheperako kwambiri womwe ungadzazebe cholumikizira chowotcherera mokwanira.
Mutha kuyeza kulowetsedwa kwa kutentha ndi liwiro laulendo pogwiritsa ntchito mkanda wowotcherera wopangidwa ndikusintha moyenera kuti muzitha kuwongolera bwino komanso zotsatira zabwino. Mwachitsanzo, ngati mutulutsa mkanda wowotcherera womwe umakhala wamtali kwambiri komanso wowonda, zikuwonetsa kuti kutentha kumakhala kotsika kwambiri komanso/kapena liwiro lanu loyenda ndilothamanga kwambiri. Mkanda wosalala, wotambasula umasonyeza kutentha kwambiri komanso/kapena kuyenda pang'onopang'ono. Sinthani magawo anu ndi luso lanu molingana kuti mukwaniritse weld yoyenera, yomwe ili ndi korona wocheperako womwe umangokhudza chitsulo mozungulira.
Mayankho awa amafunso omwe amafunsidwa pafupipafupi amangokhudza njira zingapo zabwino zowotcherera za MIG. Nthawi zonse tsatirani njira zanu zowotcherera kuti mupeze zotsatira zabwino. Komanso, zida zambiri zowotcherera ndi opanga mawaya ali ndi manambala othandizira kuti athe kulumikizana ndi mafunso. Atha kukhala chida chabwino kwambiri kwa inu.
