Thepa le Lisebelisoa tsa Argon-Hydrogen Mixtures ho Welding
Argon-hydrogen metsoakoba fumane tlhokomelo e kholo tšimong ea welding ka lebaka la thepa ea bona e ikhethang le mefuta e mengata ea likopo. Sengoliloeng sena se ikemiselitse ho hlahloba mefuta e fapaneng ea metsoako ea argon-hydrogen le ho buisana ka ts'ebeliso ea bona lits'ebetsong tsa welding. Ka ho utloisisa thepa le lits'ebetso tsena, li-welders li ka ntlafatsa mekhoa ea bona ea ho cheselletsa le ho fumana li-welds tsa boleng bo holimo.
1. Thepa ea Argon-Hydrogen Mixtures:
1.1 Kenyelletso e Eketsehileng ea Mocheso: Metsoako ea Argon-hydrogen e na le conductivity e phahameng ea mocheso ha e bapisoa le argon e hloekileng. Sena se fella ka ho eketseha ha mocheso nakong ea ts'ebetso ea welding, e lebisang ho ntlafatseng ho phunyeletsa le ho potlakisa ho potlakisa ho tjheseletsa.
1.2 Matlafatso a Matla a Arc: Ho eketsoa ha hydrogen ho argon ho ntlafatsa botsitso ba arc ka ho fokotsa ho theoha ha motlakase ho pholletsa le arc. Sena se lumella taolo e ntle ea ts'ebetso ea welding, ho fokotsa spatter le ho netefatsa hore ho na le arc e tsitsitseng ho pholletsa le weld.
1.3 Khase e Ntlafetseng ea Tšireletso: Metsoako ea Argon-hydrogen e fana ka thepa e ntle ea tšireletso, e thibelang tšilafalo ea sepakapaka ea letamo la weld. Lintho tsa haedrojene tse ka har'a motsoako li sebetsa e le khase e sebetsang, ka katleho e tlosa li-oxide le litšila tse ling sebakeng sa weld.
1.4 Sebaka se Fokotseng sa Mocheso (HAZ): Tšebeliso ea metsoako ea argon-hydrogen e fella ka HAZ e fokolang le e fokolang haholo ha e bapisoa le likhase tse ling tse sireletsang. Sena se na le molemo ka ho khetheha bakeng sa lisebelisoa tsa welding tse nang le conductivity e phahameng ea mocheso, kaha li fokotsa ho khopama le ho ntlafatsa boleng ba weld ka kakaretso.
2. Lisebelisoa tsa Argon-Hydrogen Mixtures ho Welding:
2.1 Carbon Steel Welding: Metsoako ea Argon-hydrogen e atisa ho sebelisoa bakeng sa ho cheselletsa carbon steel ka lebaka la bokhoni ba bona ba ho fana ka ho kenella ho tebileng le lebelo le phahameng la welding. Botsitso bo ntlafetseng ba arc le thepa e ntlafetseng ea tšireletso e etsa hore metsoako ena e be e loketseng bakeng sa ho fumana li-welds tse matla le tse tšoarellang lits'ebetsong tsa tšepe ea carbon.
2.2 Stainless Steel Welding: Metsoako ea Argon-hydrogen le eona e loketse bakeng sa tjheseletsa ea tšepe e sa hloekang. Lintho tse nang le hydrogen ka har'a motsoako li thusa ho tlosa li-oxide tse ka holim'a metsi, e leng se etsang hore ho be le li-welds tse hloekileng tse nang le porosity e fokotsehileng. Ho phaella moo, mocheso o ntseng o eketseha oa mocheso o lumella ho potlakisa ho potlaka ha welding, ho ntlafatsa tlhahiso ea lihlahisoa tsa tšepe tse sa hloekang.
2.3 Aluminium Welding: Le hoja metsoako ea argon-helium e atisa ho sebelisoa bakeng sa ho cheselletsa aluminium, metsoako ea argon-hydrogen e ka boela ea sebelisoa. Metsoako ena e fana ka botsitso bo betere ba arc le ts'ebetso e ntlafalitsoeng ea ho hloekisa, e hlahisang li-welds tsa boleng bo holimo tse nang le mefokolo e fokotsehileng.
2.4 Copper Welding: Metsoako ea Argon-hydrogen e ka sebelisoa bakeng sa welding ea koporo, e fana ka botsitso bo botle ba arc le ho kenya letsoho ho ntlafalitsoeng ha mocheso. Lintho tse nang le hydrogen ka har'a motsoako li thusa ho tlosa li-oxide tsa koporo, ho etsa bonnete ba hore li-welds tse hloekileng le tse matla.
Metsoako ea Argon-hydrogen e na le thepa e ikhethang e etsang hore e tšoanelehe haholo bakeng sa lits'ebetso tse fapaneng tsa welding. Kenyelletso ea bona e ntseng e eketseha ea mocheso, botsitso ba arc bo ntlafetseng, thepa e ntlafetseng ea tšireletso, le ho fokotseha ha HAZ ho ba etsa khetho e babatsehang bakeng sa tšepe ea carbon, tšepe e sa hloekang, aluminium le koporo. Ka ho sebelisa metsoako ea argon-hydrogen, li-welders li ka fumana li-welds tsa boleng bo holimo ka tlhahiso e ntlafalitsoeng le mefokolo e fokotsehileng. Ho bohlokoa hore li-welders li utloisise thepa le ts'ebeliso ea metsoako ea argon-hydrogen ho ntlafatsa mekhoa ea bona ea ho cheselletsa le ho netefatsa liphetho tse atlehileng mererong ea bona ea ho cheselletsa.
