Lithupa tsa aluminium tse cheselletsang ho sebelisa mochini oa ho tjheseletsa butt li ka ba phephetso ka lebaka la thepa e ikhethang ea aluminium.Sengoliloeng sena se hlahloba maqheka a sebetsang a ho qoba liphoso tsa ho cheselletsa le ho netefatsa tlhahiso ea li-welds tsa boleng bo holimo ha ho sebelisoa mochini oa aluminium rod butt.
1. Bohloeki ke senotlolo:
- Bohlokoa:Libaka tsa aluminium tse hloekisitsoeng hantle li bohlokoa bakeng sa li-welds tse se nang sekoli.
- Mokhoa oa ho Thibela:Hloekisa lipheletsong tsa lithupa tsa aluminium pele u tjheseletsa ho tlosa masela a oxide, litšila kapa litšila.Sebelisa mokhoa o loketseng oa ho hloekisa, joalo ka borashe ba terata kapa ho hloekisa lik'hemik'hale, ho etsa bonnete ba hore sebaka se hloekile.
2. Sepakapaka se Laolehileng:
- Bohlokoa:Aluminium e sebetsa haholo ka oksijene 'me e ka etsa likarolo tsa oxide nakong ea ho cheselletsa.
- Mokhoa oa ho Thibela:Etsa welding sebakeng se laoloang, joalo ka phaposi e sireletsang khase, ho thibela ho pepesehela oksijene.Sena se fokotsa sebopeho sa oxide nakong ea ts'ebetso ea welding.
3. Ho Lokisa le ho Lokisana hantle:
- Bohlokoa:Ho kopanya hantle le ho tsamaisana hantle ho bohlokoa bakeng sa ho tjheseletsa ka melamu ea aluminium e atlehileng.
- Mokhoa oa ho Thibela:Etsa bonnete ba hore lipheletso tsa molamu li hokahane hantle 'me li kopantsoe ka thata.Ho se tsamaisane hantle kapa likheo ho ka lebisa mefokolong ea li-welding.
4. Mekhahlelo e nepahetseng ea Welding:
- Bohlokoa:Mekhahlelo e sa nepahalang ea li-welding e ka baka boleng bo tlase le mefokolo.
- Mokhoa oa ho Thibela:Beha liparamente tsa welding, tse kang tsa hona joale, voltage, le khatello, ka har'a sebaka se khothaletsoang bakeng sa ho cheselletsa rod ea aluminium.Latela litataiso tsa moetsi oa mochini bakeng sa litlhophiso tse nepahetseng.
5. Tlhokomelo ea Electrode:
- Bohlokoa:Li-electrode li bapala karolo ea bohlokoa ts'ebetsong ea ho cheselletsa.
- Mokhoa oa ho Thibela:Kamehla hlahloba le ho boloka li-electrode tsa welding.Netefatsa hore li hloekile, ha li na tšenyo, 'me li hlophisitsoe hantle.Li-electrode tse silafetseng kapa tse senyehileng li ka lebisa ho senyeha ha li-welding.
6. Teko ea Pele ho Weld:
- Bohlokoa:Ho etsa li-welds tsa liteko ho thusa ho tseba mathata a ka bang teng pele ho tlhahiso ea tjheseletsa.
- Mokhoa oa ho Thibela:Etsa liteko tsa pre-weld ho lithupa tsa sampole ho lekola boleng ba weld le ho lokisa maemo ha ho hlokahala.Sena se lumella basebelisi ho hlophisa litlhophiso hantle le ho thibela mefokolo ho li-welds tsa tlhahiso.
7. Tlhahlobo ea Kamora ho Weld:
- Bohlokoa:Tlhahlobo ea pono ke ea bohlokoa bakeng sa ho bona mefokolo ea welding.
- Mokhoa oa ho Thibela:Lekola sebaka se cheselitsoeng ka mahlo bakeng sa matšoao leha e le afe a sekoli, joalo ka mapetsong, likheo, kapa ho tsoakana ho sa fellang.Sebelisa mekhoa ea tlhahlobo e sa senyeheng (NDT) joalo ka tlhahlobo e kenang ka dae kapa tlhahlobo ea ultrasonic bakeng sa tlhahlobo e phethahetseng.
8. Pholiso e Nepahetseng:
- Bohlokoa:Ho pholile ka potlako ho ka lebisa ho phunyeha le liphoso tse ling tsa aluminium.
- Mokhoa oa ho Thibela:Kenya ts'ebetsong mekhoa ea ho pholisa e laoloang, joalo ka ho sebelisa li-electrode tse pholileng ka metsi kapa likamore tsa ho pholisa tse laoloang, ho netefatsa hore butle-butle ho ba le sekhahla sa ho pholisa se tšoanang ka mor'a ho cheselletsa.
9. Koetliso ea Basebetsi:
- Bohlokoa:Basebelisi ba koetlisitsoeng hantle ba bohlokoa bakeng sa ho tjheseletsa ka melamu ea aluminium e atlehileng.
- Mokhoa oa ho Thibela:Fana ka koetliso e batsi ho basebetsi mabapi le liqholotso tse khethehileng le mekhoa e metle ea ho cheselletsa rod ea aluminium.Etsa bonnete ba hore ba na le tsebo ka lisebelisoa le thepa e sebelisoang.
Lithupa tsa aluminium tse sebelisang mochini oa ho tjheseletsa butt li hloka ho ela hloko lintlha tse qaqileng le ho latela mekhoa e ikhethileng ho thibela mefokolo ea welding.Ho boloka bohloeki, ho laola sepakapaka sa tjheseletsa, ho etsa bonnete ba ho lekana hantle le ho tsamaisana hantle, ho sebelisa li-parameter tse nepahetseng tsa welding, ho boloka li-electrode, ho etsa liteko tsa pele ho weld, ho etsa tlhahlobo ea post-weld, ho laola pholiso le ho fana ka koetliso ea opareitara ke mehato ea bohlokoa ea thibelo.Ka ho latela mekhoa ena, basebetsi ba ka hlahisa li-welds tse se nang sekoli 'me ba fumana liphello tsa boleng bo phahameng ho lisebelisoa tsa aluminium rod butt welding.
