Li-electrode li bapala karolo ea bohlokoa mochining oa tjheseletsa oa maqhubu a mahareng a maqhubu a mahareng. Khetho ea lisebelisoa tsa li-electrode ke ea bohlokoa bakeng sa ho fihlela li-welds tsa boleng bo holimo le ho netefatsa hore lisebelisoa tsa welding li nka nako e telele. Sengoliloeng sena se bua ka lintlha tse lokelang ho nahanoa ha u khetha lisebelisoa tsa elektrode bakeng sa mochini oa welding oa maqhubu a mahareng a maqhubu a mahareng le ho fana ka tataiso mabapi le tlhokomelo ea bona.
- Khetho ea lisebelisoa: Khetho ea thepa ea elektrode e ipapisitse le lintlha tse 'maloa, ho kenyelletsa le mofuta oa workpiece, welding hajoale, tikoloho ea welding, le boleng ba weld bo lakatsehang. Lisebelisoa tsa electrode tse sebelisoang hangata li kenyelletsa:
a. Li-Electrode tsa Copper: Koporo e sebelisoa haholo ka lebaka la ts'ebetso ea eona e ntle ea mocheso, motlakase o phahameng oa motlakase, le ho hanyetsa hantle ho apara le ho senyeha. E loketse lits'ebetso tsa welding tsa sepheo se akaretsang.
b. Li-electrode tsa Copper-Chromium-Zirconium (CuCrZr): Li-electrode tsa CuCrZr li fana ka khanyetso e ntlafetseng ea ho apara mocheso le motlakase, e leng se etsang hore li tšoanelehe bakeng sa li-welding tse phahameng tsa mocheso le lisebelisoa tse phahameng tsa morao-rao.
c. Refractory Electrodes: Lisebelisoa tse refractory tse kang tungsten, molybdenum, le li-alloys tsa tsona li khethoa bakeng sa ho tjheseletsa litšepe tse matla haholo, litšepe tse se nang tšepe le lisebelisoa tse ling tse nang le lintlha tse phahameng tse qhibilihang.
- Tlhokomelo: Tlhokomelo e nepahetseng ea li-electrode ke ea bohlokoa ho netefatsa ts'ebetso ea bona le bophelo bo bolelele. Litlhahiso tse ling tsa tlhokomelo ke tsena:
a. Ho Hloekisa Kamehla: Tlosa lithōle leha e le life, spatter ea weld, kapa oxides ho tloha holim'a li-electrode ho boloka motlakase o motle. Sebelisa lisebelisoa tse nepahetseng tsa ho hloekisa le li-solvents joalokaha ho khothalelitsoe ke moetsi oa li-electrode.
b. Electrode Dressing: Nako le nako, apara malebela a li-electrode ho boloka sebopeho le boleng ba bokaholimo. Ts'ebetso ena e kenyelletsa ho sila kapa ho lokisa ntlha ea eleketrode ho tlosa libaka tse tsofetseng kapa tse senyehileng le ho khutlisetsa geometry e lakatsehang.
c. Ho pholisa: Etsa bonnete ba hore li-electrode li pholile hantle nakong ea ts'ebetso ea li-welding, haholo-holo ha u sebelisa maqhubu a phahameng kapa li-welding tse tsoelang pele. Mocheso o feteletseng o ka lebisa ho senyeha ha li-electrode le ho fokotsa boleng ba weld.
d. Insulation: Insulate li-electrode holders 'me u netefatse hore ho kenngoa ka mokhoa o nepahetseng pakeng tsa electrode le mochine oa welding ho thibela ho tsoa ha motlakase le ho ntlafatsa polokeho.
e. Tlhokomelo: Kamehla hlahloba li-electrode bakeng sa matšoao a ho khathala, ho senyeha kapa ho senyeha. Tlosa li-electrode tse tsofetseng kapa tse senyehileng hang-hang ho boloka boleng bo nepahetseng ba weld.
Khetho ea lisebelisoa tsa elektrode mochining oa welding oa maqhubu a mahareng a maqhubu a mahareng o lokela ho nahana ka lintlha tse kang lisebelisoa tsa mosebetsi, maemo a welding, le boleng ba weld bo lakatsehang. Mekhoa e nepahetseng ea ho hlokomela, ho kenyelletsa ho hloekisa, ho roala, ho pholisa, ho kenya letsoho le ho beha leihlo, ke tsa bohlokoa ho netefatsa hore li-electrode li phela nako e telele le ho sebetsa. Ka ho khetha lisebelisoa tse loketseng tsa li-electrode le ho kenya ts'ebetsong mekhoa e metle ea tlhokomelo, li-welders li ka finyella li-welds tse tsitsitseng le tsa boleng bo phahameng lits'ebetsong tse sa tšoaneng tsa welding.
