1. Utloisisa lipeipi tsa tšepe:

 Lipeipi tsa tšepetla ka mefuta e fapaneng ea boholo, libopeho le thepa, e 'ngoe le e' ngoe e loketse lits'ebetso tse itseng.Hangata li entsoe ka tšepe ea carbon, tšepe e sa hloekang kapa tšepe ea alloy.Liphaephe tsa tšepe tsa carbon li sebelisoa haholo ka lebaka la ho khoneha le matla a tsona, ha lipeipi tsa tšepe tse sa hloekang li fana ka khanyetso e ntle ea kutu.Libakeng tse phahameng tsa mocheso, liphaephe tsa tšepe tsa alloy li khethoa.Ho utloisisa mefuta e fapaneng ea phala ea tšepe ho tla thusa ho tseba khetho e nepahetseng ea welding.

2. Khetha mokhoa oa ho tjheseletsa:

Ho na le mekhoa e fapaneng ea ho tjheseletsa e sebelisetsoang ho kopanya phala ea tšepe, ho kenyelletsa welding ea arc, TIG (tungsten inert gas) welding, MIG (metal inert gas) welding, le welding ea arc e ka tlas'a metsi.Khetho ea ts'ebetso ea welding e itšetlehile ka lintlha tse kang mofuta oa tšepe, bophara ba pipe, sebaka sa welding le moralo o kopanetsoeng.Mokhoa o mong le o mong o na le melemo le mefokolo ea oona, kahoo ho bohlokoa ho khetha mokhoa o nepahetseng ka ho fetisisa bakeng sa kopo e lakatsehang.

3. Lokisetsa phala ea tšepe:

Tokisetso e nepahetseng ea liphaephe pele ho tjheseletsa ke ea bohlokoa ho fihlela motsoako o matla le o ka tšeptjoang.E kenyelletsa ho hloekisa bokaholimo ba liphaephe ho tlosa mafome, sekala kapa litšila.Sena se ka finyelloa ka mekhoa ea ho hloekisa ka mechine e kang ho hlatsoa ka terata kapa ho sila, kapa ka ho sebelisa lisebelisoa tse hloekisang lik'hemik'hale.Ho feta moo, ho chamfering pheletso ea phala ho theha groove e nang le sebopeho sa V e lumellang ho kenella hantle ha thepa ea ho tlatsa, ka hona ho nolofatsa ts'ebetso ea welding.

4. Theknoloji ea welding:

Mokhoa oa tjheseletsa o sebelisitsoeng o ama haholo boleng ba lenonyeletso.Ho ipapisitsoe le ts'ebetso ea welding e sebelisitsoeng, ho tlameha ho bolokoa litekanyo tse loketseng tse kang oalding current, voltage, lebelo la ho tsamaea le ho kenya mocheso.Bokhoni le boiphihlelo ba motho ea cheselletsang litšepe le tsona li phetha karolo ea bohlokoa ho fihlelleng tjheseletso e ntle le e se nang sekodi.Mekhoa e kang ts'ebetso e nepahetseng ea li-electrode, ho boloka arc e tsitsitseng, le ho netefatsa phallo e lekaneng ea khase e sireletsang ho ka thusa ho fokotsa mefokolo e kang porosity kapa khaello ea fusion.

5. Tlhahlobo ea morao-rao:

Hang ha welding e felile, ho bohlokoa ho etsa tlhahlobo ea post-weld ho fumana mefokolo kapa liphoso tse ka senyang botšepehi ba lenonyeletso.Ho ka sebelisoa mekhoa ea tlhahlobo e sa senyeheng joalo ka tlhahlobo ea pono, tlhahlobo e kenang ea dae, tlhahlobo ea matla a khoheli kapa tlhahlobo ea ultrasonic.Litlhahlobo tsena li thusa ho tseba mathata a ka bang teng le ho etsa bonnete ba hore manonyeletso a cheselitsoeng a kopana le lintlha tse hlokahalang.

Ha re phethela:

 Pipe ea Tšepe Bakeng sa Weldinge hloka ho nahanisisoa ka hloko le ts'ebetso e nepahetseng ho netefatsa khokahano e sebetsang hantle le e tšepahalang.Ka ho utloisisa mefuta e fapaneng ea phala ea tšepe, ho khetha mokhoa o nepahetseng oa ho tjheseletsa, ho lokisa phala ka botlalo, ho sebelisa mekhoa e nepahetseng ea ho tjheseletsa, le ho etsa tlhahlobo ea post-weld, o ka finyella li-welds tse matla le tsa boleng bo phahameng.Sena se thusa ho ntlafatsa polokeho, ts'epahalo le bophelo ba ts'ebeletso ea liphaephe tsa tšepe lits'ebetsong tse fapaneng moo e leng likarolo tsa bohlokoa.
