Li-electrode li bapala karolo ea bohlokoa mecheng ea ho cheselletsa sebaka sa polokelo ea matla, e sebetsa e le libaka tsa puisano tse fanang ka motlakase ho theha litšepe. Sengoliloeng sena se hlahloba ts'ebeliso ea li-electrode mochining oa ho cheselletsa sebaka sa polokelo ea matla mme se fana ka leseli mabapi le tlhokomelo ea bona ho netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele.
- Mefuta ea Electrode: Mechini ea tjheseletsa ea sebaka sa polokelo ea matla e sebelisa mefuta e fapaneng ea li-electrode ho ipapisitse le ts'ebeliso e khethehileng ea welding le lisebelisoa tse cheselitsoeng. Mefuta e tloaelehileng ea li-electrode e kenyelletsa koporo, tungsten le molybdenum. Mofuta o mong le o mong o fana ka litšobotsi tse ikhethang mabapi le conductivity, ho hanyetsa mocheso, le ho tšoarella, ho lumella hore ho be le tjheseletsa e sebetsang hantle le e ka tšeptjoang.
- Khetho ea Electrode: Khetho ea li-electrode e ipapisitse le lintlha tse kang thepa e cheselitsoeng, botenya, le boleng bo lakatsehang ba weld. Li-electrode tsa koporo li sebelisoa haholo bakeng sa conductivity ea tsona e ntle ea motlakase le conductivity ea mocheso, e leng se etsang hore li tšoanelehe bakeng sa lits'ebetso tse fapaneng. Li-electrode tsa tungsten le molybdenum li khethoa bakeng sa lisebelisoa tsa ho tjheseletsa tse nang le lintlha tse phahameng tse qhibilihang, tse kang tšepe e sa hloekang kapa li-alloys tse matla haholo.
- Tlhokomelo ea Electrode: Tlhokomelo e nepahetseng ea li-electrode ke ea bohlokoa ho netefatsa hore li phela nako e telele le ts'ebetso e tsitsitseng. Ho hloekisa kamehla hoa hlokahala ho tlosa litšila tse kang oxides, litšila le spatter tse bokellanang nakong ea ho cheselletsa. Ho hloekisa ho ka etsoa ho sebelisoa lisebelisoa tse khethehileng tsa ho hloekisa, lihlapolli, kapa mekhoa ea mochini. Ho feta moo, tlhahlobo ea nako le nako ea malebela a li-electrode ho bohlokoa ho bona ho khathala, mapetsong, kapa mefokolo, e ka amang boleng ba weld. Haeba ho na le mathata a fumanoeng, li-electrode li lokela ho nkeloa sebaka kapa ho lokisoa hang-hang.
- Ho apara Electrode: Ha nako e ntse e feta, malebela a electrode a ka 'na a khathala kapa a senyeha, a ama boleng ba li-welds. Electrode dressing, eo hape e tsejoang e le reshaping kapa reconditioning, ke mokhoa oa tlhokomelo ho khutlisetsa sebopeho se lakatsehang le boemo ba bokaholimo ba ntlha ea electrode. Ho apara ho ka etsoa ka mekhoa ea ho sila, ho sebetsa ka mochine, kapa ka mekhoa ea ho ntša motlakase (EDM). Ho apara ka mokhoa o nepahetseng oa li-electrode ho tiisa ho kopana ho tsitsitseng, ho fetisa mocheso, le boleng ba weld.
- Electrode Cooling: Nakong ea welding, li-electrode li ka hlahisa mocheso o moholo, o ka amang ts'ebetso ea bona le nako ea bophelo. Ka hona, mekhoa ea ho pholisa hangata e sebelisoa ho boloka mocheso o nepahetseng oa li-electrode. Mekhoa e pholileng ea metsi kapa ea ho pholisa moea e thusa ho qhala mocheso ho tloha ho li-electrode, ho thibela ho chesa le ho lelefatsa bophelo ba bona ba ts'ebetso.
- Phetoho ea Electrode: Ho sa tsotellehe tlhokomelo e nepahetseng, li-electrode li tla qetella li felile 'me li hloka ho nkeloa sebaka. Ho lekola boemo ba li-electrode khafetsa le matšoao a ts'ebetso joalo ka bophelo ba electrode le boleng ba weld ho ka thusa ho tseba nako e nepahetseng ea ho nchafatsa. Ho nkela sebaka ka potlako ho netefatsa boleng bo tsitsitseng ba weld mme ho fokotsa kotsi ea ho hloleha ha li-electrode nakong ea ts'ebetso.
Li-electrode ke likarolo tsa bohlokoa mochining oa ho cheselletsa sebaka sa polokelo ea matla, tse thusang ho theoa ha li-welds tsa boleng bo holimo. Ka ho khetha mofuta o nepahetseng oa li-electrode, ho etsa tlhokomelo ea kamehla, ho kenyelletsa ho hloekisa, ho roala le ho pholisa, le ho nkela sebaka ka nako, li-electrode li ka ntlafatsa ts'ebetso le bophelo bo bolelele ba li-electrode. Tšebeliso e sebetsang ea li-electrode le tlhokomelo li kenya letsoho ho liphetho tse tšepahalang tsa welding, tlhahiso e eketsehang, le katleho e akaretsang lits'ebetsong tsa ho cheselletsa sebaka sa polokelo ea matla.
