1. Papiso ea ts'ebetso ea tlhahiso
Mokhoa oa tlhahiso eaphala e otlolohileng ea tšepe ea seame batla e le bonolo. Mekhoa e ka sehloohong ea tlhahiso ke seam se otlolohileng se nang le maqhubu a phahameng-frequency weldedphala ea tšepeleka tlas'a metsi arc welded otlolohileng seam tšepe phala. Peipi ea tšepe ea seam e otlolohileng e na le ts'ebetso e phahameng ea tlhahiso, theko e tlase le nts'etsopele e potlakileng.
Matla aphala ea tšepe ea spiralhangata e phahame ho feta phaephe ea tšepe ea seam e otlolohileng. Mokhoa o ka sehloohong oa tlhahiso ke welding ea arc e ka tlas'a metsi. Li-tubes tsa tšepe tsa Spiral li ka hlahisa li-tubes tse cheselitsoeng tse nang le bophara bo fapaneng ba li-billet tsa bophara bo lekanang, kapali-tubes tse cheselitsoenge nang le li-diameter tse kholoanyane ho tloha ho li-billet tse moqotetsane.
Leha ho le joalo, ha ho bapisoa le liphaephe tsa tšepe tse otlolohileng tsa bolelele bo lekanang, bolelele ba welding bo eketsehile ka 30% le 100% ka ho latellana, 'me lebelo la tlhahiso le tlaase. Ka hona, liphaephe tse kholo tsa tšepe tse bophara ba tsona hangata li cheselletsoa ka li-welding tsa spiral, 'me liphaephe tse nyane tsa tšepe tse bophara ba tsona hangata li chesetsoa ka ho otloloha ha seam.
Ha o hlahisaliphaephe tsa tšepe tse nang le bophara bo boholo bo otlolohilengindastering, ho sebelisoa theknoloji ea tjheseletsa e bōpehileng joaloka T, ke hore, palo e nyenyane ea liphaephe tsa tšepe tse otlolohileng tsa seam li kopantsoe le ho kopanngoa ho kopana le bolelele bo hlokahalang ba morero. Litšitiso tsa phala ea tšepe e otlolohileng ea sebopeho sa T e tla eketseha haholo, 'me khatello e setseng ea weld e nang le sebopeho sa T e kholo. Hangata tšepe ea weld e tlas'a khatello ea triaxial, e leng ho eketsang monyetla oa ho phunyeha.
Ntle le moo, ho latela melaoana ea tekheniki ea welding ea arc e ka tlas'a metsi, weld e 'ngoe le e' ngoe e tla ba tlas'a ts'ebetso ea arc e otlang le ea ho tima arc. Leha ho le joalo, phala e 'ngoe le e' ngoe ea tšepe e ke ke ea kopana le boemo bona nakong ea ho tjheseletsa seam circumferential, kahoo ho ka 'na ha e-ba le mefokolo e eketsehileng nakong ea ho tima arc.
2. Papiso ea litekanyetso tsa ts'ebetso
Ha phala e tlas'a khatello ea ka hare, likhatello tse peli tse ka sehloohong hangata li hlahisoa leboteng la liphaephe, e leng khatello ea mahlaseli le khatello ea axial. Comprehensive stress at the weld, moo α Ke weld spiral angle ofphala ea tšepe ea spiral.
Khatello e akaretsang ho spiral weld ke khatello e kholo ea phala ea tšepe ea seam e otlolohileng. Tlas'a khatello e ts'oanang ea ts'ebetso, botenya ba lerako la liphaephe tsa tšepe tsa spiral tse nang le bophara bo lekanang ba phaephe bo nyane ho feta ba liphaephe tsa tšepe tse otlolohileng.
