Tlhaloso ea Sehlahisoa
LSAW (Longitudinal Submerged Arc Welding) lipeipi tsa tšepe ke mofuta oa phala ea tšepe e cheselitsoeng e khetholloang ka mokhoa oa bona o ikhethang oa tlhahiso le mefuta e mengata ea lisebelisoa.Liphaephe tsena li etsoa ka ho etsa poleiti ea tšepe hore e be sebopeho sa cylindrical le ho e cheseletsa ka nako e telele ho sebelisoa mekhoa ea ho tjheseletsa ka har'a metsi.Mona ke kakaretso ea liphaephe tsa tšepe tsa LSAW:
Mokhoa oa Tlhahiso:
● Ho Lokisetsa Plate: Lipoleiti tsa tšepe tsa boleng bo phahameng li khethoa ho latela litlhoko tse khethehileng, ho netefatsa thepa ea mochine e lakatsehang le metsoako ea lik'hemik'hale.
● Ho Bopa: Letlapa la tšepe le bōptjoa hore e be phala ea cylindrical ka mekhoa e kang ho kobeha, ho bilika kapa ho tobetsa (JCOE le UOE).Mathoko a kobehile pele ho thusa ho cheseletsa.
● Welding: Ho sebelisoa li-arc welding (SAW) tse ka tlas'a metsi, moo arc e bolokiloeng tlas'a lera la flux.Sena se hlahisa li-welds tsa boleng bo holimo tse nang le bofokoli bo fokolang le fusion e ntle haholo.
● Tlhahlobo ea Ultrasonic: Ka mor'a ho cheselletsa, ho etsoa tlhahlobo ea ultrasonic ho fumana mefokolo leha e le efe ea ka hare kapa ea ka ntle sebakeng sa weld.
● Ho Atolosoa: Pipe e ka atolosoa ho finyella bophara bo lakatsehang le botenya ba lerako, ho matlafatsa ho nepahala ha dimensional.
● Tlhatlhobo ea ho Qetela: Teko e felletseng, ho kenyeletsoa tlhahlobo ea pono, tlhahlobo ea boholo, le liteko tsa thepa ea mochini, li netefatsa boleng ba phaephe.
Melemo:
● Tšebeliso ea Litšenyehelo: Liphaephe tsa LSAW li fana ka tharollo e theko e tlaase bakeng sa liphaephe tsa bophara bo boholo le lisebelisoa tsa meralo ka lebaka la ts'ebetso ea tsona ea tlhahiso e sebetsang hantle.
● Matla a Phahameng: Mokhoa oa ho tjheseletsa oa longitudinal o fella ka liphaephe tse nang le thepa e matla le e tšoanang ea mechine.
● Ho nepahala ha Dimensional: Liphaephe tsa LSAW li bonts'a litekanyo tse nepahetseng, tse etsang hore li tšoanelehe bakeng sa likopo tse nang le mamello e thata.
● Boleng ba Weld: Welding ea arc e ka tlas'a metsi e hlahisa li-welds tsa boleng bo phahameng tse nang le motsoako o babatsehang le mefokolo e fokolang.
● Liphaephe tsa LSAW li sebelisoa liindastering tse sa tšoaneng, tse akarelletsang oli le khase, kaho le phepelo ea metsi, ka lebaka la ho ikamahanya le maemo le ho tšoarella ha tsona.
Ka kakaretso, liphaephe tsa tšepe tsa LSAW li etsoa ka mokhoa o nepahetseng le o sebetsang hantle, o hlahisang liphaephe tse ngata, tse theko e tlaase, le tse tšoarellang tse loketseng mekhoa e mengata ea indasteri.
