Ho welding ea sebaka sa maqhubu a mahareng, khetho ea li-electrode e bapala karolo ea bohlokoa ho fihlelleng liphetho tse lakatsehang tsa welding. Mefuta e fapaneng ea li-electrode e ka ba le litlamorao tse fapaneng ho boleng ba weld, ts'ebetso ea ts'ebetso, le ts'ebetso ka kakaretso. Sengoliloeng sena se ikemiselitse ho lekola liphetho tsa welding tse fumanoeng ka li-electrode tse fapaneng ho li-welding tse mahareng tsa frequency inverter spot.
Copper Electrodes:
Li-electrode tsa koporo li sebelisoa haholo ho tjheseletsa matheba ka lebaka la conductivity ea tsona e ntle ea mocheso le conductivity e phahameng ea motlakase. Li fana ka phetisetso e sebetsang ea mocheso, e bakang ho futhumala ka potlako le ho ts'oanang ha li-workpieces. Li-electrode tsa koporo li boetse li bonts'a khanyetso e ntle ea ho roala le ho senyeha, ho netefatsa ts'ebetso e tsitsitseng ea welding ho feta ts'ebeliso e telele. Li-welds tse fihletsoeng ka li-electrode tsa koporo hangata li bonts'a matla a matle, ts'epahalo le spatter e nyane.
Lielektrone tsa Chromium Zirconium Copper (CuCrZr):
Li-electrode tsa CuCrZr li tsebahala ka ho thatafala ha tsona le ho hanyetsa ho khomarela li-electrode. Ho eketsoa ha chromium le zirconium ho ntlafatsa thepa ea holim'a electrode, ho fokotsa tšekamelo ea hore tšepe e qhibilihisitsoeng e khomarele sebaka sa electrode nakong ea ho tjheseletsa. Tšobotsi ena e fokotsa tšilafalo ea li-electrode, e lelefatsa bophelo ba li-electrode, 'me e ntlafatsa ponahalo ea weld. Li-welds tse entsoeng ka li-electrode tsa CuCrZr hangata li bonts'a pheletso e ntlafalitsoeng ea bokaholimo le moaparo o fokolitsoeng oa li-electrode.
Refractory Electrodes (mohlala, Tungsten Copper):
Li-electrode tsa refractory, joalo ka koporo ea tungsten, li ratoa bakeng sa lits'ebetso tsa welding tse kenyelletsang mocheso o phahameng kapa lisebelisoa tse thata. Li-electrode tsena li fana ka ho hanyetsa mocheso o babatsehang le ho tšoarella nako e telele, li etsa hore li tšoanelehe bakeng sa mekhoa ea ho cheseletsa e hlokang nako e telele ea mocheso kapa ho kenyelletsa lisebelisoa tse nang le lintlha tse phahameng tsa ho qhibiliha. Li-electrode tsa refractory li ka mamella maemo a thata a ho tjheseletsa le ho boloka ts'ebetso e tsitsitseng, e leng se hlahisang li-welds tse tšepahalang tse nang le li-electrode tse nyane.
Li-electrode tse koahetsoeng:
Li-electrode tse koahetsoeng li etselitsoe ho fana ka ts'ebetso e itseng kapa ho rarolla mathata a itseng a ho cheselletsa. Ka mohlala, li-electrode tse nang le liaparo tse khethehileng li ka fana ka khanyetso e ntlafetseng ea ho khomarela, ho fokotsa spatter, kapa ho matlafatsa tšireletso khahlanong le ho apara. Liaparo tsena li ka etsoa ka lisebelisoa tse kang silevera, nickel kapa li-alloys tse ling, tse etselitsoeng ho finyella litlhoko tse khethehileng tsa ho cheselletsa. Li-electrode tse koahetsoeng li ka kenya letsoho ho ntlafatseng chebahalo ea weld, mefokolo e fokotsehileng, le ho lelefatsa bophelo ba li-electrode.
Li-electrode tse kopantsoeng:
Li-electrode tse kopaneng li kopanya lisebelisoa tse fapaneng ho ntlafatsa melemo ea tsona ka bomong. Ka mohlala, electrode e kopantsoeng e ka 'na ea e-ba le motheo oa koporo o pota-potiloeng ke lera la lintho tse refractory. Moqapi ona o kopanya melemo ea mocheso o phahameng oa mocheso o tsoang ho koporo le ho hanyetsa mocheso o babatsehang ho tloha thepa ea refractory. Li-electrode tse kopantsoeng li fana ka tekanyo pakeng tsa ts'ebetso le katleho ea litšenyehelo, li fana ka liphello tse ka tšeptjoang tsa welding lits'ebetsong tse fapaneng.
Khetho ea li-electrode ka har'a li-welding tse mahareng tsa frequency inverter spot welding e ama haholo liphetho tsa welding. Li-electrode tsa koporo li sebelisoa hangata ka lebaka la ts'ebetso ea tsona e ntle ea mocheso le motlakase. Li-electrode tsa CuCrZr li fana ka boima bo ntlafetseng le ho khomarela li-electrode tse fokotsehileng. Li-electrode tsa refractory li loketse lits'ebetso tsa mocheso o phahameng, ha li-electrode tse koahetsoeng li fana ka mesebetsi e itseng. Li-electrode tse kopantsoeng li kopanya lisebelisoa tse fapaneng ho fihlela ho leka-lekana ha litšobotsi tsa ts'ebetso. Ka ho khetha li-electrode tse nepahetseng ho ipapisitsoe le litlhoko tse ikhethileng tsa welding, bahlahisi ba ka fihlela boleng bo lakatsehang ba weld, ts'ebetso e sebetsang hantle, le ts'ebetso e akaretsang ts'ebetsong ea welding ea maqhubu a mahareng.
