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 zingayambitse 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 pokhapokha ngati sikuchepera zero.

Mosasamala mtundu wa chingwe cha mkuwa, ndondomeko yowotcherera idzatulutsa utsi woyera, kutanthauza kuti ngakhale zinki sizitsulo zolemera, ngati malo owotcherera alibe mpweya wokwanira, utsi woyera ukhoza kukhumudwitsa dongosolo la kupuma, makamaka mapapu, kapena ngati wogwira ntchito savala chigoba, pambuyo pa mphindi 30 za ntchito, iwo 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, kona yowotcherera (10 ° -30 °) sikoyenera, koma ngodya iyi yokha imatha kuthetsa vuto losungunuka la tungsten argon arc kuwotcherera.

Ngati mukufuna kupeza chowotcherera chapamwamba, musaope mtengo wokwera mtengo, tikulimbikitsidwa kugwiritsa ntchito waya wonyezimira kwambiri wotetezedwa ndi waya wotchinga, kuwotcherera kudzagwira ntchito bwino, koma mtengo wake ndi wokwera kwambiri, ndipo kuwotcherera kwa TIG sikutsika mtengo.Mwachidule, kuwotcherera mabasi amkuwa ndi kutentha kwakukulu, ngodya yaying'ono komanso ntchito yoteteza kwambiri.
