Ho Rarolla Mathata a Tloaelehileng a Welding ka Malebela a Saha a Tungsten Carbide

    Welding tungsten carbide (WC) e bone malebela a lisebelisoa tsa ho seha ke ts'ebetso ea bohlokoa e amang ts'ebetso le nako e telele ea lisebelisoa. Leha ho le joalo, ts'ebetso ena hangata e ka hlahisa liphephetso tseo, ha li sa rarolloe, li ka bakang ho hloleha ho sehlahisoa sa ho qetela. Ho utloisisa litaba tse tloaelehileng tsa welding le litharollo tsa tsona ke tsa bohlokoa bakeng sa ho netefatsa li-welds tsa boleng bo holimo le ts'ebetso e nepahetseng ea lisebelisoa. Sengoliloeng sena se bua ka mathata a atileng a kopaneng nakong ea ho cheselletsa malebela a tungsten carbide mme se fana ka maano a sebetsang a ho rarolla mathata.

1. Ho Kena ho sa Lekaneng

Bothata: Ho kenella ho sa lekaneng ho etsahala ha weld e sa kenelle ka ho feletseng lisebelisoa tsa motheo, tse lebisang ho manonyeletso a fokolang a ka hlōlehang tlas'a khatello ea kelello.

Lisosa: Ho Kena ha Mocheso o fokolang: Ha ho mocheso o lekaneng o ka thibelang ho qhibiliha ho nepahetseng ha thepa ea motheo.

Boemo bo sa nepahaleng ba Electrode: Lehlakore kapa sebaka se sa nepahalang se ka fokotsa phetisetso e sebetsang ea mocheso.

Litharollo: Fetola Li-parameter tsa Welding: Eketsa litlhophiso tsa amperage le voltage ho fana ka mocheso o mongata. Netefatsa hore lebelo la leeto le nepahetse ho lumella ho qhibiliha ho lekaneng.

Optimize Electrode Angle: Beha electrode sebakeng se nepahetseng le sebaka se hole ho netefatsa hore mocheso o ajoa hantle.

2. Ho petsoha ka Weld

Bothata: Ho petsoha ho ka etsahala sebakeng sa weld kapa sebakeng se amehileng ke mocheso (HAZ), se lebisang ho hloleheng ho hoholo.

Lisosa: Mocheso o Feteletseng: Ho futhumala ho feteletseng ho ka baka khatello ea mocheso, ho baka mapetsong.

Lintho tse silafatsang: Oli, grease, kapa oxidation holim'a bokaholimo li ka lebisa ho kopantseng hampe le ho peperana.

Litharollo: Laola Mocheso: Sebelisa mekhoa e kang pulse welding ho fokotsa ho kenya mocheso le ho thibela mocheso o feteletseng. Preheat substrate ha ho hlokahala ho fokotsa mocheso oa mocheso.

Tlhoekiso e Hloekileng: Netefatsa hore libaka tsohle li hloekisoa ka hloko pele li cheseletsa ho felisa litšila.

3. Porosity

Bothata: Porosity e bolela ho ba teng ha lipokotho tsa khase ka har'a weld, e fokolisang lenonyeletso 'me e ka lebisa ho hlōleha pele ho nako.

Lisosa: Tšireletso e sa lekaneng: Tšireletso e sa lekaneng ho tsoa ho litšila tsa sepakapaka nakong ea ts'ebetso ea welding e ka hlahisa likhase.

Mongobo ho Thepa ea Filler: Haeba thepa ea ho tlatsa e monya mongobo, e ka hlahisa khase nakong ea ts'ebetso ea welding.

Litharollo: Ntlafatsa Tšireletso: Netefatsa hore sekhahla sa phallo ea khase se lekane ebile se tsitsitse. Ka TIG welding, netefatsa hore khase e koahelang e lekane ho sireletsa letamo la weld.

Lisebelisuoa tsa Dry Filler: Boloka lisebelisoa tsa li-filler hantle ho thibela ho monya mongobo, 'me u li sebelise hang ka mor'a ho bula.

4. Fusion e Fosahetseng

Bothata: Ho kopanya ho fokolang ho etsahala ha ntlha ea tungsten carbide e sa kopane ka ho feletseng le substrate, e lebisang ho manonyeletso a fokolang.

Lisosa: Mokhoa o sa nepahalang oa Welding: Mocheso o sa lekaneng kapa angle e fosahetseng ea welding e ka thibela ho kopanngoa ho nepahetseng.

Ho se lumellane ha lintho tse bonahalang: Liphapang tsa li-coefficients tsa ho atolosa mocheso pakeng tsa lisebelisoa li ka lebisa ho se kopane ho sa lekaneng.

Litharollo: Fetola Mekhoa ea ho Welding: Leka ka lebelo le fapaneng la li-welding, li-angles, le litlhophiso tsa mocheso ho ntlafatsa fusion. Etsa bonnete ba hore mokhoa oa ho cheselletsa o lumella ho qhibiliha ho lekaneng ha carbide le substrate.

Khetha Lisebelisoa tse Lumellanang: Sebelisa lisebelisoa tsa li-filler tse tsamaellanang le thepa ea mocheso ea tungsten carbide le thepa ea motheo.

5. Khopamiso e Feteletseng

Bothata: Ho khopama ho feteletseng ho ka etsahala nakong ea ho cheselletsa, e leng se lebisang ho sotheng ha lehare la sakha kapa ho se lumellane ha malebela.

Lisosa: Ho futhumatsa ho sa Lekaneng: Ho futhumala ka potlako le ho tsidifala ho ka baka ho honyela ho sa leka-lekaneng le ho atoloha.

Tšehetso e sa Lekaneng: Haeba workpiece e sa tšehetsoe ka ho lekaneng, e ka fetoha nakong ea welding.

Litharollo: Laola likhahla tsa ho futhumatsa le ho pholisa: Kenya ts'ebetsong mekhoa ea ho futhumatsa pele le ho laola mokhoa oa ho pholisa ho fokotsa likhahla tsa mocheso. Liphekolo tsa mocheso oa post-weld le tsona li ka thusa ho imolla khatello ea maikutlo.

Fana ka Tšehetso e Lekaneng: Sebelisa lisebelisoa kapa li-jigs ho tsitsisa workpiece nakong ea welding, ho netefatsa hore e lula e lumellane.

Qetello

Ho rarolla mathata a tloaelehileng a ho cheselletsa ka li-welding tsa tungsten carbide ho hloka kutloisiso e phethahetseng ea ts'ebetso ea ho cheselletsa le mathata a ka bang teng. Ka ho hlokomela lisosa tsa mathata a kang ho se kenelle ho lekaneng, ho petsoha, porosity, ho kopanngoa ho fokolang, le ho sotha ho feteletseng, bahlahisi ba ka sebelisa litharollo tse sebetsang ho ntlafatsa boleng ba li-welld tsa bona. Tlhokomelo e tsoelang pele le tokiso ea li-parameter tsa welding, hammoho le boitokiso bo hlokolosi le bohloeki, li bohlokoa bakeng sa ho fihlela ts'ebetso e nepahetseng ho lisebelisoa tsa tungsten carbide. Ha indasteri ea tšepe e thata e ntse e tsoela pele, ho boloka litekanyetso tse phahameng tsa mekhoa ea ho cheselletsa ho tla lula ho le bohlokoa bakeng sa ho hlahisa lisebelisoa tse ka tšeptjoang le tse sebetsang hantle tsa ho itšeha.
