Ho Khetha Lisebelisoa tsa Electrode Bakeng sa Mechini ea Welding ea Maqhubu a Mahare a Maqhubu?

Ho khetha thepa e nepahetseng ea li-electrode ke qeto ea bohlokoa ho netefatsa katleho le ho tšoarella ha mechini ea welding ea sebaka se mahareng.Sengoliloeng sena se bua ka lintlha tse lokelang ho nahanoa ha u khetha lisebelisoa tsa elektrode mme se fana ka leseli mabapi le ts'ebetso ea khetho.

1. Tšebelisano 'moho le Mosebetsi:Thepa ea elektrode e lokela ho lumellana le lisebelisoa tse cheselitsoeng.Ho bohlokoa ho nahana ka lintlha tse kang conductivity, katoloso ea mocheso, le ts'ebetso ea lik'hemik'hale ho thibela phetiso ea thepa le tšilafalo nakong ea welding.
2. Electrode Wear Resistance:Khetha lisebelisoa tse nang le khanyetso e phahameng ea ho roala ho mamella khatello ea mochini le ea mocheso eo u kopanang le eona nakong ea ts'ebetso ea welding.Lisebelisoa tse kang li-alloys tsa koporo, koporo ea chromium, le litšepe tse refractory li tsejoa ka ho hanyetsa ha tsona ho apara.
3. Ho hanyetsa Mocheso le Thermal Conductivity:Li-electrode li lokela ho ba le khanyetso e ntle ea mocheso ho thibela ho senyeha kapa ho qhibiliha pele ho nako nakong ea ho cheselletsa.Ho phaella moo, boemo bo loketseng ba mocheso oa mocheso o thusa ho felisa mocheso o hlahisoang nakong ea ts'ebetso ea ho cheselletsa.
4. Khokahano ea Motlakase:Motlakase o phahameng o bohlokoa bakeng sa phetisetso e nepahetseng ea matla ho tloha mochining oa welding ho ea ho workpiece.Koporo le li-alloys tsa eona, ka lebaka la conductivity ea tsona e babatsehang, li atisa ho sebelisoa lisebelisoa tsa electrode.
5. Corrosion Resistance:Nahana ka tikoloho ea tjheseletsa ho khetha lisebelisoa tse fanang ka khanyetso e lekaneng ea kutu.Sena ke sa bohlokoa haholo ha o sebetsa ka thepa e ka senyehang habonolo kapa maemong a mongobo.
6. Litšenyehelo le ho ba Teng:Ho bohlokoa ho leka-lekanya tšebetso le litšenyehelo.Le ha thepa e kang tungsten ea koporo e fana ka thepa e ikhethang, e ka ba theko e boima ho feta.Lekola litlhoko tsa tjheseletsa le likhaello tsa tekanyetso ha u khetha lisebelisoa tsa elektrode.
7. Qetello ea Bokaholimo le ho Koaheloa:Lisebelisoa tse ling li rua molemo ka ho roala li-electrode tse matlafatsang ho hanyetsa, ho thibela ho khomarela, kapa ho fokotsa spatter.Liaparo tse kang chrome plating kapa li-electrode dressing li ka eketsa bophelo ba ts'ebetso ea electrode.

Ho khetha lisebelisoa tsa Electrode:

1. Lisebelisoa tsa Copper le Copper:Tsena li sebelisoa haholo bakeng sa conductivity ea tsona e ntle ea motlakase, conductivity e ntle ea mocheso, le ho hanyetsa ho apara.Li-alloys tse kang Sehlopha sa 2 (C18200) le Sehlopha sa 3 (C18150) li-alloys tsa koporo ke likhetho tse tloaelehileng.
2. Chromium Copper:Li-alloys tsa koporo tsa Chromium (CuCrZr) li fana ka khanyetso e phahameng ea ho apara, motlakase o motle oa motlakase, le botsitso ba mocheso.Li loketse likopo tse hlokang ho cheselletsa.
3. Lisebelisoa tsa Tungsten-Copper:Li-electrode tsa koporo tsa Tungsten li kopanya thepa ea sebaka se phahameng sa ho qhibiliha sa tungsten le conductivity ea koporo.Li loketse likopo tse hlokang ho hanyetsa mocheso o phahameng.
4. Molybdenum:Li-electrode tsa Molybdenum li sebelisoa bakeng sa lits'ebetso tse ikhethileng tse hlokang ho hanyetsa mocheso o phahameng le katoloso e tlase ea mocheso.

Khetho ea lisebelisoa tsa li-electrode bakeng sa mechini ea tjheseletsa ea maqhubu a mahareng e ipapisitse le lintlha tse fapaneng, ho kenyeletsoa ho tsamaellana le lisebelisoa tsa mosebetsi, ho hanyetsa, ho hanyetsa mocheso, conductivity ea motlakase le litšenyehelo.Ka ho hlahloba lintlha tsena ka hloko le ho utloisisa litlhoko tse khethehileng tsa ho tjheseletsa, bahlahisi ba ka khetha thepa e nepahetseng ea electrode e tlatsetsang ts'ebetsong e sebetsang hantle le ea boleng bo phahameng.
