Kukhala ndi zida zoyenera pakuwotcherera ndikofunikira - ndipo kuwonetsetsa kuti zikugwira ntchito pakufunika ndikofunika kwambiri.
Kulephera kwa mfuti zowotcherera kumayambitsa kutaya nthawi ndi ndalama, osatchulapo kukhumudwa. Mofanana ndi zina zambiri za ntchito yowotcherera, njira yofunika kwambiri yopewera vutoli ndi maphunziro. Kumvetsetsa momwe mungasankhire bwino, kukhazikitsa ndi kugwiritsa ntchito mfuti ya MIG kungathandize kukonza zotsatira ndikuchotsa mavuto ambiri omwe amachititsa kuti mfuti iwonongeke.
Phunzirani za zifukwa zisanu zomwe zimadziwika kuti MIG mfuti zimalephera komanso momwe mungapewere.
Kumvetsetsa momwe mungasankhire bwino, kukhazikitsa ndi kugwiritsa ntchito mfuti ya MIG kungathandize kukonza zotsatira ndikuchotsa mavuto ambiri omwe amachititsa kuti mfuti iwonongeke.
Chifukwa 1: Kupitilira mfuti
Kuyeza pamfuti ya MIG kumawonetsa kutentha komwe chogwirira kapena chingwe chimakhala chofunda movutikira. Miyezo iyi sikuwonetsa pomwe mfuti yowotcherera ingayambitse kuwonongeka kapena kulephera.
Kusiyana kwakukulu kuli pakugwira ntchito kwa mfuti. Chifukwa opanga amatha kuwerengera mfuti zawo pa 100%, 60% kapena 35% yantchito, pangakhale kusiyana kwakukulu poyerekeza zopangidwa ndi opanga.
Kuzungulira kwa ntchito ndi kuchuluka kwa nthawi yokhazikika mkati mwa mphindi 10. Wopanga m'modzi atha kupanga mfuti ya 400-amp GMAW yomwe imatha kuwotcherera pa 100% yantchito, pomwe wina amapanga mfuti yomweyi yomwe imatha kuwotcherera pa 60% yokha. Mfuti yoyamba imatha kuwotcherera bwino bwino kwa mphindi 10, pomwe yomalizayo imatha kutenthetsa bwino kwa mphindi 6 isanatenthedwe kwambiri.
Sankhani mfuti yokhala ndi ma amperage rating omwe amagwirizana ndi ntchito yofunikira komanso kutalika kwa nthawi yomwe wogwiritsa ntchitoyo aziwotcherera. M'pofunikanso kuganizira zipangizo ndi filler zitsulo waya kuti ntchito. Mfutiyo iyenera kunyamula mphamvu zokwanira kusungunula waya wazitsulo zodzaza bwino komanso mosasinthasintha.
Chifukwa 2: Kukonzekera kolakwika ndi kukhazikitsa pansi
Kukonzekera kolakwika kwadongosolo kungapangitse chiopsezo cha kulephera kwa mfuti zowotcherera. Ndikofunika kulabadira osati zolumikizira zonse zomwe zimagwiritsidwa ntchito mkati mwa mfuti, komanso maulumikizidwe onse pagawo lonse la weld kuti muwongolere magwiridwe antchito.
Kuyika pansi koyenera kumathandiza kuti wogwiritsa ntchitoyo asatumize mphamvu zambiri pawindo loletsedwa kuti azitha kudutsamo. Kulumikizana kwapansi kotayirira kapena kosayenera kungapangitse kukana mumayendedwe amagetsi.
Onetsetsani kuti mwayika pansi pafupi ndi chogwirira ntchito momwe mungathere - patebulo lomwe limagwira ntchito. Izi zimathandiza kupereka dongosolo loyera kwambiri la dera lamphamvu kuti liziyenda komwe likuyenera kupita.
Kulephera kwa mfuti zowotcherera kumayambitsa kutaya nthawi ndi ndalama, osatchulapo kukhumudwa. Mofanana ndi zina zambiri za ntchito yowotcherera, njira yofunika kwambiri yopewera vutoli ndi maphunziro.
Ndikofunikiranso kuyika pansi pamalo aukhondo kuti pakhale kukhudzana kwachitsulo ndi chitsulo; osagwiritsa ntchito utoto wopaka kapena wakuda. Malo oyera amapatsa mphamvu mphamvu njira yosavuta kuyenda m'malo mopanga zotchinga zomwe zimapangitsa kukana - zomwe zimawonjezera kutentha.
Chifukwa 3: Malumikizidwe otayirira
Malumikizidwe ogwiritsidwa ntchito amagwira ntchito yofunika kwambiri pakuchita mfuti. Zogwiritsidwa ntchito ziyenera kutetezedwa mwamphamvu kumfuti, ndipo zolumikizira zonse zolumikizidwa ziyenera kukhala zotetezedwa. Ndikofunikira kwambiri kuyang'ana ndi kukhwimitsa zolumikizira zonse mfuti itakonzedwa kapena kukonzedwa.
Nsonga yolumikizana kapena khosi lamfuti ndikuyitanitsa kulephera kwa mfuti pamalopo. Ngati zolumikizira sizili zolimba, kutentha ndi kukana zimatha kukula. Komanso, onetsetsani kuti cholumikizira chilichonse chomwe chikugwiritsidwa ntchito chikugwira ntchito bwino ndipo chimapereka mphamvu nthawi zonse.
Chifukwa 4: Chingwe chamagetsi chowonongeka
Zingwe zimatha kuwonongeka mosavuta m'sitolo kapena malo opangira zinthu; mwachitsanzo, ndi zida zolemera kapena kusungirako kosayenera. Kuwonongeka kulikonse kwa chingwe chamagetsi chiyenera kukonzedwa mwamsanga.
Yang'anani chingwe ngati chadulidwa kapena kuwonongeka; palibe mkuwa womwe uyenera kuwululidwa mbali iliyonse ya chingwe. Mzere wowonekera wa mphamvu mu weld system idzayesa kulumpha arc ngati ikhudza chilichonse chachitsulo kunja kwa dongosolo. Izi zingayambitse kulephera kwakukulu kwadongosolo komanso kukhala ndi nkhawa yokhudzana ndi chitetezo.
Tsitsaninso mfutiyo ndikupangitsa chingwe kukhala chachifupi ngati kuli kofunikira, kuchotsa zigawo zilizonse za chingwe zomwe zili ndi nicks kapena mabala.
Onetsetsaninso kuti chingwe chamagetsi ndi kukula koyenera kwa mphamvu yomwe wodyetsa akupereka kumfuti yowotcherera. Chingwe champhamvu chokulirapo chimawonjezera kulemera kosafunikira, pomwe chingwe chocheperako chimayambitsa kutentha.
Sankhani mfuti yokhala ndi ma amperage rating omwe amagwirizana ndi ntchito yofunikira komanso kutalika kwa nthawi yomwe wogwiritsa ntchitoyo aziwotcherera.
Chifukwa 5: Zowopsa za chilengedwe
Malo opangira zinthu amatha kukhala ovuta kwa zida ndi zida. Samalirani zida ndi zida zothandizira kuwonjezera moyo wawo wothandiza. Kudumpha kukonza kapena kusagwiritsa ntchito bwino zida kungayambitse kulephera komanso kuchepetsa moyo.
Ngati mfuti yowotcherera ilumikizidwa ndi mkono wa boom pamwamba pa weld cell, onetsetsani kuti palibe madera omwe mfuti kapena chingwe chingathe kupinidwa kapena kuonongeka. Khazikitsani selo kuti pakhale njira yomveka bwino ya chingwe, kupewa kuphwanya chingwe kapena kusokoneza kayendedwe ka gasi.
Kugwiritsa ntchito anangula amfuti kumathandiza kuti mfutiyo ikhale yabwino komanso chingwe chowongoka - kupewa kupanikizika kwambiri pa chingwe - pamene mfuti sikugwiritsidwa ntchito.
Malingaliro owonjezera pakulephera kwa mfuti za MIG
Kulephera kwa mfuti pamfuti zowotcherera zoziziritsidwa ndi madzi zimachitika pafupipafupi kuposa kulephera kwamfuti zoziziritsidwa ndi mpweya. Izi zachitika makamaka chifukwa cha kukhazikitsidwa kosayenera.
Mfuti yowotcherera yozizidwa ndi madzi imafuna choziziritsa kuzizira kuti iziziziritsa. Choziziriracho chiyenera kukhala chikuthamanga mfuti isanayambe chifukwa kutentha kumachuluka mofulumira. Kukanika kukhala ndi chiller akuthamanga pamene kuwotcherera kuyambika kudzawotcha mfutiyo - zomwe zimafuna kuti mfuti yonse ilowe m'malo mwake.
Chidziwitso cha welder ndi chidziwitso chokhudza momwe mungasankhire pakati pa mfutizi ndi kuzisunga zingathandize kupewa zambiri zomwe zimabweretsa kulephera. Zing'onozing'ono zimatha kukhala chipale chofewa kukhala zazikulu mkati mwa dongosolo, kotero ndikofunikira kupeza ndi kuthetsa mavuto ndi mfuti yowotcherera pamene ayamba kupewa mavuto aakulu pambuyo pake.
Malangizo Osamalira
Kutsatira malangizo ena ofunikira pakuwongolera zodzitetezera kungathandize kukulitsa moyo wamfuti yowotcherera ndikupangitsa kuti igwire bwino ntchito. Zimathandizanso kuchepetsa mwayi wokonzanso mwadzidzidzi zomwe zimatha kuchotsa weld cell.
Kuwunika pafupipafupi mfuti ya MIG kungakhale gawo lofunikira pakuchepetsa mtengo komanso kupeza ntchito yabwino yowotcherera. Kukonzekera koteteza sikuyenera kukhala nthawi yambiri kapena zovuta.
Yang'anani kulumikizidwa kwa feeder pafupipafupi.Kulumikizana kwa mawaya otayirira kapena akuda kumapangitsa kuti kutentha kuchuluke ndipo kumapangitsa kutsika kwamagetsi. Limbitsani zolumikizira ngati pakufunika ndikusintha ma O-ringing owonongeka ngati pakufunika.
Samalirani bwino mzere wa mfuti.Zovala zamfuti nthawi zambiri zimatha kudzaza ndi zinyalala panthawi yowotcherera. Gwiritsani ntchito mpweya woponderezedwa kuti muchotse chotchinga chilichonse akasintha waya. Tsatirani malangizo a wopanga podula ndi kukhazikitsa liner.
Onani chogwirira ndi choyambitsa.Zigawozi nthawi zambiri zimafunikira kusamalidwa pang'ono kuposa kungoyang'ana. Yang'anani ming'alu pa chogwirira kapena zomangira zomwe zikusowa, ndipo onetsetsani kuti chowombera mfuti sichimamatira kapena sichikuyenda bwino.
Yang'anani khosi lamfuti.Kulumikizana kotayirira kumapeto kwa khosi kumatha kuyambitsa kukana kwamagetsi komwe kumapangitsa kuti weld asamayende bwino kapena kulephera kugwiritsa ntchito. Onetsetsani kuti zolumikizira zonse zili zolimba; yang'anani mowoneka ma insulators pakhosi ndikusintha ngati awonongeka.
Yang'anani chingwe chamagetsi.Kuwunika pafupipafupi chingwe chamagetsi ndikofunikira kuti muchepetse mtengo wa zida zosafunika. Yang'anani mabala kapena ma kinks mu chingwe ndikusintha ngati kuli kofunikira.
