Li-electrode tsa welding ke lithapo tsa tšepe tse phehiloeng holim'a liaparo tsa lik'hemik'hale.Molamu o sebelisetsoa ho ts'ehetsa arc ea ho cheselletsa le ho fana ka tšepe ea ho tlatsa e hlokahalang hore lenonyeletso le be le cheselle.Ho roala ho sireletsa tšepe ho senya, ho tsitsisa arc, le ho ntlafatsa weld.Bophara ba terata, ho fokotsa ho roala, ho lekanya boholo ba molamu oa welding.Sena se hlahisoa ka likaroloana tsa lisenthimithara tse kang 3/32 ″, 1/8″, kapa 5/32.Bophara bo bonyenyane bo bolela hore bo hloka chelete e fokolang ea hona joale 'me e kenya tšepe e nyenyane ea ho tlatsa.
Mofuta oa tšepe ea motheo e cheselitsoeng, mokhoa oa ho tjheseletsa le mochine, le maemo a mang a etsa qeto ea mofuta oa electrode e sebelisoang.Ka mohlala, k'habone e tlaase kapa "tšepe e bonolo" e hloka molamu o bonolo oa welding.Welding cast cast iron, aluminium kapa koporo e hloka lithupa le lisebelisoa tse fapaneng.
Ho roala ha flux ho li-electrode ho etsa qeto ea hore na e tla sebetsa joang nakong ea ts'ebetso ea 'nete ea welding.E 'ngoe ea li-coating li chesa le ho chesoa ha metsi ho etsa mosi' me e sebetsa e le thebe e pota-potileng "letamo" la ho cheselletsa, ho le sireletsa moeeng o potolohileng lona.Karolo e 'ngoe ea flux e qhibiliha ebe e tsoakana le terata ebe e phaphamala litšila ka holimo.Litšila tsena li tsejoa e le "slag".Weld e phethiloeng e ka ba brittle mme e fokola haeba e se bakeng sa flux.Ha motsoako o nang le welded o pholile, slag e ka tlosoa.Ho sebelisoa hamore le borashe ba terata ho hloekisa le ho hlahloba cheseletso.
Li-electrode tsa tšepe-arc welding li ka hlophisoa e le li-electrode tse se nang letho, li-electrode tse koahetsoeng ka leseli, le arc e sirelelitsoeng kapa li-electrode tse koahetsoeng ka boima.Mofuta o sebelisoang o itšetlehile ka thepa e khethehileng e hlokahalang e kenyeletsang: ho hanyetsa kutu, ductility, matla a phahameng a tsitsipano, mofuta oa tšepe ea motheo e lokelang ho chesetsoa;le boemo ba tjheseletsa bo bataletseng, bo tshekaletseng, bo otlolohileng, kapa ka hodimo.
