Ho khetha li-electrode tse nepahetseng bakeng sa mochini oa welding oa "medium-frequency inverter spot welding" ho bohlokoa ho fihlela li-welds tsa boleng bo holimo. Sengoliloeng sena se fana ka tataiso e felletseng ea ho thusa basebelisi ho etsa liqeto tse nang le tsebo ha ba khetha li-electrode. Ka ho nahana ka lintlha tse kang ho lumellana ha thepa, sebōpeho le boholo ba li-electrode, likhetho tsa ho roala, le bophelo ba li-electrode, basebetsi ba ka ntlafatsa mekhoa ea bona ea ho tjheseletsa le ho fumana li-welds tse tšepahalang le tse sebetsang hantle.
- Tšebelisano ea lintho tse bonahalang: Ntho ea pele eo u lokelang ho e ela hloko ha u khetha li-electrode ke ho lumellana ha tsona le thepa e cheselitsoeng. Lisebelisoa tse fapaneng tsa elektrode li loketse lits'ebetso tse ikhethileng le lisebelisoa tsa mosebetsi. Lisebelisoa tse tloaelehileng tsa electrode li kenyelletsa li-alloys tsa koporo, koporo ea chromium-zirconium, tungsten-koporo le molybdenum. Ikopanye le litataiso tsa li-welding, litlhaloso tsa thepa, le litsebi tsa ho tjheseletsa ho fumana lisebelisoa tsa elektrode tse loketseng litlhoko tsa hau tse ikhethang.
- Sebopeho sa Electrode le Boholo: Sebopeho le boholo ba li-electrode li phetha karolo ea bohlokoa ts'ebetsong ea ho cheselletsa. Li-electrode li fumaneha ka litlhophiso tse fapaneng, ho kenyeletsoa flat, pointed, le domed. Khetho ea sebopeho sa electrode e itšetlehile ka lintlha tse kang botenya ba workpiece, boholo ba weld le matla a lakatsehang, le ho fihlella sebakeng sa weld. Khetha sebopeho sa elektrode se fanang ka khokahano e nepahetseng le kabo ea hajoale bakeng sa ts'ebeliso e khethehileng ea welding.
- Likhetho tsa ho roala: Li-electrode li ka koaheloa ho ntlafatsa ts'ebetso ea tsona le ho tšoarella. Liaparo tse tloaelehileng li kenyelletsa nickel, chrome, le titanium nitride. Liaparo li ka ntlafatsa ho hanyetsa ho apara, ho fokotsa ho khomarela tšepe e qhibilihisitsoeng, le ho fana ka conductivity e ntle ea motlakase. Nahana ka litlhoko tse khethehileng tsa kopo ea hau ea welding, e kang ho hanyetsa mocheso o phahameng kapa thepa e khahlanong le ho khomarela, ha u khetha liphahlo tsa electrode.
- Bophelo ba Electrode: Nako ea bophelo ea li-electrode ke taba ea bohlokoa ho netefatsa ts'ebetso ea litšenyehelo le tlhahiso e sa sitisoeng. Lintlha tse amang bophelo ba li-electrode li kenyelletsa hona joale oa welding, frequency ea welding, lisebelisoa tsa elektrode le tlhokomelo e nepahetseng. Khetha li-electrode tse nang le nako e loketseng ea bophelo tse ka mamellang boima bo lebelletsoeng ba ho tjheseletsa. Kamehla hlahloba le ho boloka li-electrode ho lelefatsa bophelo ba bona ba ts'ebeletso le ho ntlafatsa ts'ebetso ea welding.
- Litlhahiso tsa Moetsi: Sheba litlhahiso le litlhaloso tsa moetsi oa li-electrode bakeng sa tataiso e eketsehileng. Hangata bahlahisi ba fana ka lintlha tse qaqileng mabapi le khetho ea li-electrode, litataiso tsa tšebeliso, le litšobotsi tsa ts'ebetso. Ela hloko tsebo ea moetsi le phihlelo ea ho etsa li-electrode ha u etsa khetho ea hau.
- Teko le Tlhahlobo: Ho etsa li-welds tsa liteko ho sebelisa likhetho tse fapaneng tsa li-electrode ho ka thusa ho fumana khetho e nepahetseng ka ho fetisisa. Lekola boleng ba weld, chebahalo le ts'ebetso ea eleketrode ka 'ngoe ho lekola hore na e lumellana joang le ts'ebeliso e khethehileng ea welding. Nahana ka lintlha tse kang matla a weld, nugget formation, le liaparo tsa electrode.
Ho khetha li-electrode tse nepahetseng ho bohlokoa bakeng sa ho fihlela ts'ebetso e nepahetseng le li-welds tsa boleng bo holimo mecheng ea li-welding tse mahareng tsa maqhubu a mahareng. Nahana ka lintlha tse kang tšebelisano ea thepa, sebopeho le boholo ba li-electrode, likhetho tsa ho roala, bophelo ba li-electrode, likhothaletso tsa moetsi, le liphetho tsa tlhahlobo le tlhahlobo. Ka ho etsa liqeto tse nang le tsebo, basebelisi ba ka khetha li-electrode tse eketsang tlhahiso, li netefatsa bots'epehi ba weld, le ho fihlela litlhoko tsa bona tse ikhethileng tsa ts'ebeliso.
