Mokhoa oa ho bonts'a boemo ba tšepe ea welding: Tšepe ea welding e kenyelletsa tšepe ea carbon bakeng sa welding, tšepe ea alloy bakeng sa welding, tšepe e sa hloekang bakeng sa welding, joalo-joalo. tjheseletsa tšepe kereiti. Ka mohlala H08, H08Mn2Si, H1Cr18Ni9. Bakeng sa tšepe ea boleng bo phahameng ba boleng bo phahameng, eketsa letšoao "A" qetellong ea sehlopha. Ka mohlala H08A, H08Mn2SiA.

Ho sebelisoa hangatalipeipi tsa tšepe tse cheselitsoengli arotsoe ka mefuta e meraro e latelang ho latela lits'ebetso tsa welding tse sebelisoang tlhahiso ea tsona.
① Peipi ea tšepe e tsoelang pele ea ho cheseletsa sebōpi: E tšoauoa ka katleho e phahameng ea tlhahiso le litšenyehelo tse tlase tsa tlhahiso, empa motsoako oa metallurgic oa lenonyeletso le cheselitsoeng ha oa phethahala, boleng ba weld ha bo bobe, 'me thepa e felletseng ea mochini e fokola.

② Resistance welded steel pipe: E tšoauoa ka katleho e phahameng ea tlhahiso, tekanyo e phahameng ea boiketsetso, ha ho hlokahale lithupa tsa welding le flux nakong ea welding, tšenyo e nyane ea tšepe ea motheo, le deformation e nyane le khatello e setseng ka mor'a ho cheselletsa. Leha ho le joalo, thepa ea eona ea tlhahiso e rarahane, matsete a thepa a phahame, 'me litlhoko tsa boleng ba holim'a li-welded joints le tsona li batla li phahame.

③ Arc welded steel pipe: Tšobotsi ea eona ke hore lenonyeletso le nang le welded le fihlella tlamahano e felletseng ea metallurgical, mme thepa ea mochini ea lenonyeletso e ka fihla ka botlalo kapa ea ba haufi le thepa ea mochini oa thepa ea motheo. Ho ea ka sebopeho sa weld, liphaephe tsa tšepe tse entsoeng ka arc li ka aroloa ka liphaephe tse otlolohileng tsa seam le liphaephe tse cheselitsoeng ka spiral; ho latela mekhoa e fapaneng ea ts'ireletso e sebelisoang nakong ea welding, liphaephe tsa tšepe tse cheselitsoeng ka arc li ka aroloa ka liphaephe tsa tšepe tse kentsoeng ka tlas'a metsi le liphaephe tsa tšepe tse qhibilihang tsa arc. Ho na le mefuta e 'meli ea lipeipi tsa tšepe tse cheselitsoeng.
