Ho tjheseletsa arc e kenelletseng ka boiketsetso ho sebelisoa ho kopanya mathoko a likhoele hammoho, ho etsa weld e tsoelang pele ho potoloha bolelele ba phaephe. Mokhoa ona o netefatsa hore lenonyello le matla ebile lea tšoarella ha ka nako e ts'oanang le fokotsa liphoso le ho boloka botsitso ba sebopeho.

Melemo ea phala ea tšepe ea carbon e svetselitsoeng ka spiral

1. Matla le ho tšoarella:Pipe ea tšepe ea k'habone e welded ka spirale tsebahala ka matla a eona a phahameng le ho tšoarella, e leng se etsang hore e lokele lits'ebetso tse hlokang khanyetso e phahameng ea khatello le ts'ebetso ea nako e telele.

2. Ho Sebetsa ka Botlalo: Liphaephe tsena li fana ka tharollo e theko e tlaase ka lebaka la ts'ebetso ea tsona e sebetsang hantle ea tlhahiso, litšenyehelo tse tlase tsa thepa e tala, le litlhoko tse fokotsehileng tsa basebetsi ha li bapisoa le mefuta e meng ea liphaephe.

3. Ho feto-fetoha ha maemo: Ho feto-fetoha ha phaephe ea tšepe ea khabone e spirale e bōpehileng joaloka tšepe ho e lumella ho sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa le lipalangoang tsa metsi, lipalangoang tsa oli le khase, mehaho ea ho bokella likhoerekhoere, litsamaiso tsa likhoerekhoere le lits'ebetso tse fapaneng tsa indasteri.

4. Ho nepahala ha litekanyo: Ts'ebetso ea ho theha spiral e ka laola boholo le botenya ba lebota la phaephe ka nepo, e netefatsa ho nepahala le ho tšoana ha tlhahiso.
