Zovuta pakuwotcherera zingwe zamkuwa

Mzere wamkuwaali wabwino magetsi ndi matenthedwe madutsidwe, koma pali mavuto ambiri zovuta ndondomeko kuwotcherera.The matenthedwe conductivity lamba mkuwa wofiira kwambiri kuposa zitsulo.Kutentha kwa kuwotcherera kumakhala kosavuta kutayika, zomwe zimapangitsa kuti pakhale kupsinjika kwambiri mkati, zomwe zimapangitsa kuti kuwotcherera kumasokonekera ndi zovuta zina zowotcherera.Choncho, kutentha ndende chofunika pa kuwotcherera.Njira zowotcherera zimaphatikizapo kuwotcherera kwa tungsten argon arc ndi kuwotcherera kwa plasma.Kuphatikiza apo, kutentha koyenera kuyenera kuchitidwa musanawotchere.Kuwotcha pang'ono sikuyenera kutenthedwa malinga ngati sikuchepera zero.

Mosasamala mtundu wa chingwe chamkuwa, njira yowotcherera idzatulutsa utsi woyera, kutanthauza kuti ngakhale nthaka sizitsulo zolemera, ngati malo otsekemera alibe mpweya wabwino, utsi woyera ukhoza kukwiyitsa dongosolo la kupuma, makamaka mapapu, kapena ngati wogwira ntchitoyo akuyenda bwino. osavala chigoba, pambuyo pa mphindi 30 za ntchito, adzagwa.Tepi yofiira yamkuwa ndiyowotcherera, zinthuzo ziyenera kukhala zofanana ndi zapansi.Pa kuwotcherera wamba kokha, φ2.5-φ4 waya wamba wamkuwa angagwiritsidwe ntchito.

Mzere wamkuwa wamadzimadzi umakhala ndi 70% yokha yachitsulo.N'zosavuta kupanga dziwe losungunuka muzitsulo zowotcherera, ndipo muzu sudzasungunuka.Kuti muthane ndi vutoli, muyenera kuyamba ndi njira yowotcherera yomweyi ndikumaliza.Kumayambiriro kwa kuwotcherera, kuwotcherera ngodya (10 ° -30 °) sikoyenera, koma ngodya iyi yokha imatha kuthetsa vuto losungunuka la tungsten argon arc kuwotcherera.

Ngati mukufuna kupeza chowotcherera apamwamba, musawope mtengo wokwera mtengo, Ndi bwino kugwiritsa ntchito inert mpweya wotetezedwa Flux cored waya, kuwotcherera ntchito bwino, koma mtengo ndi mkulu kwambiri, ndi TIG kuwotcherera. palokha si yotsika mtengo.Mwachidule, kuwotcherera mabasi amkuwa ndi kutentha kwakukulu, ngodya yaying'ono komanso ntchito yoteteza kwambiri.
