Resistance spot welding ke mokhoa o sebelisoang haholo oa ho tjheseletsa o itšetlehileng ka li-electrode ho theha li-welds tse matla le tse tšepahalang ka thepa e fapaneng. Khetho ea li-electrode tse nepahetseng ke ea bohlokoa molemong oa katleho ea ts'ebetso ea ho cheselletsa letheba. Sehloohong sena, re tla fana ka tataiso e akaretsang mabapi le mokhoa oa ho khetha li-electrode tsa ho tjheseletsa letheba.
1. Ho utloisisa Mefuta ea Electrode
Li-electrode tsa Resistance spot welding li tla ka mefuta e fapaneng, e 'ngoe le e' ngoe e etselitsoe lits'ebetso tse ikhethileng. Mefuta e tloaelehileng ea li-electrode e kenyelletsa:
- Copper Electrodes:Tsena li na le mekhoa e mengata 'me li loketse mefuta e mengata ea thepa, ho akarelletsa le tšepe, aluminium le koporo.
- Chromium-Copper Electrodes:E loketse bakeng sa ho tjheseletsa lisebelisoa tse matla haholo le bakeng sa lits'ebetso tse hlokang bophelo bo atolositsoeng ba li-electrode.
- Li-electrode tsa Tungsten-Copper:E tsebahala ka ho tšoarella ha eona le bokhoni ba ho sebetsana le lits'ebetso tse futhumatsang haholo, joalo ka lisebelisoa tse teteaneng tsa welding.
- Molybdenum Electrodes:E sebelisoa bakeng sa ho cheselletsa thepa e sa tloaelehang joalo ka titanium le lits'ebetso tse hlokang ho hanyetsa mocheso o phahameng.
Ho utloisisa litšobotsi le tšebeliso e reriloeng ea mofuta o mong le o mong oa li-electrode ho bohlokoa ho etsa khetho e nepahetseng.
2. Ho lumellana ha Lintho
Khetha li-electrode tse tsamaellanang le thepa eo u rerang ho e cheseletsa. Lisebelisoa tse fapaneng tsa li-electrode li ka sebelisana ka tsela e fapaneng le litšepe tse fapaneng. Netefatsa hore li-electrode li loketse sebopeho se ikhethileng sa thepa le botenya ba li-workpieces tsa hau.
3. Sebopeho sa Electrode le Boholo
Sebopeho le boholo ba li-electrode li phetha karolo ea bohlokoa ho boleng ba li-welds. Khetha libopeho tsa li-electrode tse lumellanang le geometry ea sebaka sa weld. Boholo ba li-electrode bo lokela ho ba bo loketseng bakeng sa botenya ba workpiece ho netefatsa kabo e nepahetseng ea mocheso le ho kenella nakong ea welding.
4. Liaparo tsa Electrode
Li-electrode tse ling li koahetsoe ka lisebelisoa tse kang zirconium, tse ka ntlafatsang ts'ebetso ea tsona le ho lelefatsa bophelo ba tsona. Nahana ka li-electrode tse koahetsoeng bakeng sa lits'ebetso moo li-welds tse tsitsitseng le tsa boleng bo holimo li leng bohlokoa.
5. Mekhoa ea ho Pholisa
Lits'ebetsong tsa mocheso o phahameng, ho pholisa ho bohlokoa ho thibela tšenyo ea li-electrode. Li-electrode tse ling li tla le lisebelisoa tse hahelletsoeng ka har'a metsi, tse kang li-electrode tse pholileng ka metsi, tse ka thusang ho boloka mocheso oa tsona le ho lelefatsa bophelo ba tsona.
6. Tebello ea Bophelo ba Electrode
Nahana ka nako e lebeletsoeng ea bophelo ea li-electrode, haholo-holo bakeng sa libaka tse phahameng tsa tlhahiso ea li-welding. Le hoja li-electrode tse ling li ka 'na tsa e-ba le nako e khutšoanyane ea bophelo, li na le litšenyehelo tse ngata ho li nkela sebaka. Tse ling, joalo ka li-electrode tsa chromium-copper kapa tungsten-copper, li na le nako e telele ea bophelo empa li ka ba theko e boima qalong.
7. Tlhokomelo ea Electrode
Tlhokomelo ea kamehla ea li-electrode ke ea bohlokoa ho netefatsa boleng bo tsitsitseng ba tjheseletsa. Li-electrode tse ling li ka hloka tlhokomelo khafetsa ho feta tse ling. Nahana ka boiketlo ba tlhokomelo ha u khetha li-electrode bakeng sa kopo ea hau.
8. Litlhokomelo tsa Lichelete
Leha ho le bohlokoa ho khetha li-electrode tse nepahetseng bakeng sa ts'ebeliso ea hau, mathata a tekanyetso le ona e ka ba lebaka. Lekola litšenyehelo tsa li-electrode mabapi le ts'ebetso ea tsona e lebelletsoeng le nako ea bophelo.
9. Mofani oa Botumo
Khetha barekisi ba tsebahalang ba tsebahalang ka ho fana ka li-electrode tsa boleng bo holimo le tšehetso e ntle ea bareki. Barekisi ba tšepahalang ba ka fana ka tataiso mabapi le khetho ea li-electrode le ho fana ka thuso ha ho hlokahala.
Qetellong, khetho ea li-electrode tsa "resistance spot welding" li kenyelletsa ho shebisisa ka hloko mefuta ea li-electrode, ho lumellana ha thepa, sebopeho le boholo, liaparo, mekhoa ea ho pholisa, nako ea bophelo ea li-electrode, litlhoko tsa tlhokomelo, likhaello tsa tekanyetso, le botumo ba mofani oa thepa. Ka ho ela hloko lintlha tsena, o ka etsa liqeto tse nang le tsebo le ho netefatsa ts'ebetso e atlehileng ea li-welding ka li-welds tse matla le tse tšepahalang.
