Liphaephe tsa tšepe tsa LSAW (Longitudinal Submerged Arc Welding) ke mofuta oa phaephe ea tšepe e bōpehileng joaloka thapo e nang le ts'ebetso ea eona e ikhethang ea tlhahiso le mefuta e mengata ea lits'ebetso. Liphaephe tsena li etsoa ka ho etsa poleiti ea tšepe ka sebopeho sa cylindrical le ho e tjheseletsa ka bolelele ho sebelisoa mekhoa ea ho tjheseletsa ea arc e qoelitsoeng. Mona ke kakaretso ea liphaephe tsa tšepe tsa LSAW:

Mokhoa oa Tlhahiso:
● Tokiso ea Lipoleiti: Lipoleiti tsa tšepe tsa boleng bo holimo li khethoa ho latela litlhoko tse itseng, ho netefatsa litšobotsi tse lakatsehang tsa mechini le motsoako oa lik'hemik'hale.
● Ho Theha: Poleiti ea tšepe e bōpehile joaloka phaephe e chitja ka mekhoa e kang ho kobeha, ho phutholla, kapa ho hatella (JCOE le UOE). Meeli e kobehile esale pele ho nolofatsa ho tjheseletsa.
● Ho tjheseletsa: Ho tjheseletsa arc e kentsweng ka metsing (SAW) ho sebediswa, moo arc e bolokwang tlasa lera la flux. Sena se hlahisa di-weld tsa boleng bo hodimo tse nang le diphoso tse fokolang le ho kopanngwa ho hotle haholo.
● Tlhahlobo ea Ultrasonic: Kamora ho tjheseletsa, ho etsoa liteko tsa ultrasound ho fumana liphoso leha e le life tsa ka hare kapa tsa kantle sebakeng sa tjheseletsa.
● Ho Atolosa: Phaephe e ka atolosoa ho fihlela bophara bo lakatsehang le botenya ba lebota, e leng se ntlafatsang ho nepahala ha litekanyo.
● Tlhahlobo ea ho Qetela: Teko e felletseng, ho kenyeletsoa le tlhahlobo ea pono, liteko tsa boholo, le liteko tsa thepa ea mechini, li netefatsa boleng ba phaephe.

Melemo:
● Ho Boloka Litšenyehelo: Liphaephe tsa LSAW li fana ka tharollo e theko e tlaase bakeng sa liphaephe tse bophara bo boholo le lits'ebetso tsa meaho ka lebaka la ts'ebetso ea tsona e sebetsang ea tlhahiso.
● Matla a Phahameng: Mokhoa oa ho tjheseletsa o molelele o fella ka liphaephe tse nang le thepa e matla le e ts'oanang ea mechini.
● Ho Nepahala ha Dikarolo: Diphaephe tsa LSAW di bontsha dibopeho tse nepahetseng, e leng se etsang hore di lokele ditshebediso tse nang le mamello e tiileng.
● Boleng ba ho Weld: Ho weld ea arc e qoelitsoeng ka metsing ho hlahisa li-weld tsa boleng bo holimo tse nang le motsoako o motle le liphoso tse fokolang.
● Ho Feto-fetoha ha Metsi: Liphaephe tsa LSAW li sebelisoa liindastering tse fapaneng, ho kenyeletsoa oli le khase, kaho le phepelo ea metsi, ka lebaka la ho ikamahanya le maemo le ho tšoarella ha tsona.

Ka bokhutšoanyane, liphaephe tsa tšepe tsa LSAW li etsoa ka mokhoa o nepahetseng le o sebetsang hantle, e leng se fellang ka liphaephe tse feto-fetohang, tse theko e tlaase, le tse tšoarellang tse loketseng mefuta e mengata ea lits'ebetso tsa indasteri.
