Mu ntchito zowotcherera za MIG, kukhala ndi njira yolumikizira waya ndikofunikira. Waya wowotcherera uyenera kudyetsedwa mosavuta kuchokera ku spool pa chodyetsa kudzera pa pini yamagetsi, liner ndi mfuti mpaka kunsonga yolumikizirana kuti akhazikitse arc. Izi zimalola wowotchererayo kuti azigwira ntchito mokhazikika komanso kuti akhale ndi mtundu wabwino wa weld, komanso kuchepetsa nthawi yotsika mtengo yothetsa mavuto ndi kukonzanso komwe kungachitike.
Komabe, pali zovuta zingapo zomwe zingasokoneze kuyatsa kwa waya. Izi zingayambitse mavuto ambiri, kuphatikizapo kusinthasintha kwa arc, zowotcha (kupanga chowotcherera mkati kapena pansonga yolumikizirana) ndi birdnesting (kulumikizana kwa waya mumayendedwe oyendetsa). Kwa ogwiritsa ntchito kuwotcherera kwatsopano omwe mwina sadziwa bwino njira yowotcherera ya MIG, mavutowa amatha kukhala okhumudwitsa kwambiri. Mwamwayi, pali njira zothetsera mavuto mosavuta ndikupanga njira yodalirika yodyetsera waya.
Kutalika kwa chowotcherera kumakhudza kwambiri momwe waya angadyetsere njira yonse. Kutalikirapo kwa liner kumatha kupangitsa kuti kinking ndi kusadya bwino kwa waya, pomwe liner yomwe ili yaifupi kwambiri siipereka chithandizo chokwanira ku waya ikadutsa. Izi zitha kutsogolera ku micro-arcing mkati mwa nsonga yolumikizana yomwe imayambitsa kuyatsa kapena kulephera kwanthawi yake. Zitha kukhalanso chifukwa cha arc yosokonekera komanso kukwera kwa mbalame.
Chepetsani liner molondola ndikugwiritsa ntchito njira yoyenera
Tsoka ilo, zovuta zowotcherera zowotcherera ndizofala, makamaka pakati pa ogwiritsa ntchito omwe sakudziwa zambiri. Kuti mutengerepo ntchito yochepetsera chowotcherera mfuti molondola - ndikukwaniritsa njira yodyetsera mawaya yopanda cholakwika - lingalirani kachitidwe kamene kamachotsa kufunika koyezera chingwe kuti mulowe m'malo. Dongosololi limatsekera lineryo kumbuyo kwa mfuti, zomwe zimalola wowotchererayo kuti azidula ndi pini yamagetsi. Mbali ina ya liner imatseka kutsogolo kwa mfuti pansonga yolumikizana; imalumikizidwa molunjika pakati pa mfundo ziwirizi, kotero kuti lineryo isatalikike kapena kutsika pakasuntha mwachizolowezi.
Dongosolo lomwe limatseka chingwe kumbuyo kwa mfuti ndi kutsogolo limapereka njira yolumikizira waya yosalala - mpaka pakhosi kupita kuzinthu zogwiritsidwa ntchito ndi zowotcherera - monga momwe tawonetsera pano.
Mukamagwiritsa ntchito liner wamba, pewani kupotoza mfuti podula liner ndipo gwiritsani ntchito sikelo yoyezera liner ikaperekedwa. Zingwe zokhala ndi mbiri yamkati zomwe zimapangitsa kuti pakhale mikangano pang'ono pawaya wowotcherera pamene idutsa pa liner ndi chisankho chabwino kuti mupeze mawaya abwino. Izi zimakhala ndi zokutira zapadera pa iwo ndipo zimakulungidwa kuchokera kuzinthu zazikulu, zomwe zimapangitsa kuti mzerewo ukhale wolimba komanso umapereka chakudya chosalala.
Gwiritsani ntchito nsonga yabwino yolumikizirana ndikukhazikitsa molondola
Kufananiza kukula kwa nsonga yolumikizirana yolumikizirana ndi kukula kwa waya ndi njira ina yosungira njira yolumikizira waya yomveka bwino. Mwachitsanzo, waya wa 0.035-inchi uyenera kufananizidwa ndi nsonga yolumikizirana m'mimba mwake. Nthawi zina, zingakhale bwino kuchepetsa nsonga yolumikizana ndi kukula kumodzi kuti mupeze mawaya abwino komanso kuwongolera kwa arc. Funsani wopanga zowotcherera wodalirika kapena wogawa zowotcherera kuti akulimbikitseni.
Yang'anani kuvala ngati mawonekedwe a keyholing (pamene nsonga yolumikizanayo imakhala yonyezimira) chifukwa izi zingayambitse kuyaka komwe kumalepheretsa waya kudyetsa.
Onetsetsani kuti mwayika nsonga yolumikizirana bwino, ndikuyimitsa kupitilira chala kuti musatenthe kwambiri, zomwe zingalepheretse kudyetsa waya. Onani bukhu lothandizira lochokera kwa wopanga nsonga zolumikizirana zowotcherera kuti muwone momwe ma torque akulimbikitsidwa.
Liner yokonzedwa molakwika imatha kupangitsa kuti mbalame ziwonjezeke kapena kumangirira waya pamagalimoto oyendetsa, monga momwe tawonetsera pano.
Sankhani masikono oyendetsa bwino ndikukhazikitsa zovuta bwino
Ma drive rolls amathandizira kwambiri kuwonetsetsa kuti mfuti yowotcherera ya MIG ili ndi njira yolumikizira waya.
Kukula kwa mpukutu woyendetsa kuyenera kufanana ndi kukula kwa waya womwe ukugwiritsidwa ntchito ndipo kalembedwe kamadalira mtundu wa waya. Mukawotchera ndi waya wolimba, V-groove drive roll imathandizira kudyetsa bwino. Mawaya amtundu wa Flux - onse a gasi komanso odziteteza - komanso mawaya azitsulo amagwira ntchito bwino ndi ma V-knurled drive rolls. Pakuwotcherera aluminium, gwiritsani ntchito mipukutu yoyendetsa ya U-groove; mawaya a aluminiyamu ndi ofewa kwambiri, kotero kuti sitayeloyi siwaphwanyire kapena kuwawononga.
Kuti mukhazikitse kugwedezeka kwa mpukutu wagalimoto, tembenuzirani ndodo ya waya kuti mutembenuzire theka lakudutsa. Kokani chowombera pamfuti ya MIG, kudyetsa waya m'dzanja lamagetsi ndikulipiringitsa pang'onopang'ono. Waya ayenera kudyetsa popanda kutsetsereka.
Mvetserani momwe waya wowotcherera amakhudzira pakutha
Ubwino wa waya wowotcherera komanso mtundu wa zoyika zake zonse zimakhudza kudyetsa waya. Waya wapamwamba kwambiri amakhala ndi mainchesi okhazikika kuposa otsika, zomwe zimapangitsa kuti zikhale zosavuta kudyetsa kudzera mudongosolo lonse. Imakhalanso ndi kuponyedwa kosasinthasintha (m'mimba mwake pamene kutalika kwa waya kumadulidwa spool ndi kuikidwa pamtunda wathyathyathya) ndi helix (kutalika kwa waya kumatuluka pamtunda), zomwe zimawonjezera kudyetsa kwa waya.
Ngakhale mawaya apamwamba amatha kuwononga ndalama zam'tsogolo, angathandize kuchepetsa ndalama zomwe zimatenga nthawi yayitali pochepetsa chiopsezo cha kudyetsa.
Yang'anani nsonga yolumikizirana ndi keyholing, chifukwa imatha kuyambitsa zowotcha (kupangidwa kwa chowotcherera mkati kapena pansonga yolumikizirana) monga tawonera m'fanizoli.
Waya wochokera ku ng'oma zazikulu nthawi zambiri amakhala ndi mawonekedwe akulu akatulutsidwa kuchokera m'matumba, motero amakonda kudya mowongoka kuposa mawaya a spool. Ngati kuchuluka kwa ng'oma yowotcherera kungathe kuthandizira ng'oma yokulirapo, izi zitha kukhala zoganizira pazakudya zonse zamawaya komanso kuchepetsa nthawi yosinthira.
Kupanga ndalama
Kuphatikiza pa kutsata njira zabwino zopangira njira yoperekera waya - komanso kudziwa momwe mungathetsere mavuto mwachangu - kukhala ndi zida zodalirika ndikofunikira. Kugulitsa kwapatsogolo kopangira mawaya apamwamba kwambiri komanso zinthu zowotcherera zokhazikika zimatha kulipira pakapita nthawi pochepetsa zovuta komanso mtengo wokhudzana ndi zovuta zamawaya. Kutsika pang'ono kumatanthauza kuyang'ana kwambiri pakupanga magawo ndikuwafikitsa kwa makasitomala.
