Resistance spot welding ke mokhoa o sebelisoang haholo oa ho kopanya litšepe tse fapaneng, ho kenyeletsoa li-alloys tsa koporo.Mokhoa ona o itšetlehile ka tšebeliso ea mocheso o hlahisoang ke ho hanyetsa motlakase ho etsa li-welds tse matla, tse tšoarellang.Sehloohong sena, re tla hlahloba ts'ebetso ea ho hanyetsa letheba la li-alloys tsa koporo le ho tšohla mehato ea bohlokoa e amehang.
Ho utloisisa I
1. Tokisetso ea Lintho:
Pele o qala ts'ebetso ea welding, ho bohlokoa ho etsa bonnete ba hore likotoana tsa alloy tsa koporo tse tla kopanngoa li hloekile ebile ha li na litšila.Litšila leha e le life tse ka holimo li ka ama boleng ba weld hampe.Ho hloekisa hangata ho etsoa ho sebelisoa borashe ba terata kapa solvent ea lik'hemik'hale.
2. Khetho ea Li-Electrode:
Khetho ea li-electrode e bohlokoa molemong oa ho cheselletsa sebaka sa ho hanyetsa.Li-electrode li lokela ho etsoa ka thepa e khonang ho mamella mocheso o phahameng o hlahisoang nakong ea ts'ebetso ea ho cheselletsa.Li-electrode tsa koporo li sebelisoa hangata bakeng sa li-alloys tsa koporo ka lebaka la conductivity ea tsona e ntle le ho tšoarella nako e telele.
3. Ho beha Liparamente tsa Welding:
Ho beha li-parameter tsa welding hantle ho bohlokoa bakeng sa ho fumana weld e atlehileng.Li-parameter tse lokelang ho nahanoa li kenyelletsa:
- Welding current: Palo ea motlakase o sebelisoang nakong ea ho cheselletsa.
- Nako ea welding: Nako eo hona joale e sebelisoang ka eona.
- Electrode force: Khatello e sebelisoang ho li-workpieces ke li-electrode.
Litekanyetso tse khethehileng tsa liparamente tsena li tla itšetleha ka botenya le sebopeho sa motsoako oa koporo o cheselitsoeng.
4. Mokhoa oa ho cheselletsa:
Hang ha li-parameter tsa welding li se li behiloe, mokhoa oa sebele oa ho tjheseletsa o ka qala.Lisebelisoa li behiloe lipakeng tsa li-electrode, ho netefatsa khokahano e ntle ea motlakase.Ha motlakase o sebelisoa, ho hanyetsa libakeng tsa ho kopana ho hlahisa mocheso, ho etsa hore motsoako oa koporo o qhibilihe ebe o kopanya hammoho.Matla a electrode a tiisa ho kopana ho nepahetseng mme a thusa ho theha weld.
5. Ho pholisa le ho Hlahloba:
Ka mor'a ho cheselletsa, ho bohlokoa ho lumella weld ho pholile ka tlhaho kapa ka ho sebelisa mokhoa o laoloang oa ho pholisa ho thibela ho thehoa ha likoli.Hang ha o pholile, weld e lokela ho hlahlojoa boleng.Sena se kenyelletsa ho hlahloba hore na ha ho na mapetsong, porosity, le fusion e nepahetseng.Haeba ho lemohuoa sekoli leha e le sefe, cheseterole e ka 'na ea hloka ho lokisoa kapa ho nchafatsoa.
6. Kalafo ea Kamor'a Weld:
Maemong a mang, kalafo ea post-weld e ka hlokahala ho ntlafatsa thepa ea mochini oa weld kapa ho fokotsa khatello e setseng.Sena se ka kenyelletsa lits'ebetso tse joalo ka ho fokotsa khatello ea maikutlo kapa khatello ea maikutlo.
Qetellong, resistance spot welding ke mokhoa o atlehang haholo oa ho kopanya li-alloys tsa koporo ha o etsoa ka nepo.Ka ho latela mehato e boletsoeng ka holimo le ho laola ka hloko li-welding parameters, hoa khoneha ho etsa li-welds tse matla le tse ka tšeptjoang ka li-alloys tsa koporo, ho etsa hore mokhoa ona e be sesebelisoa sa bohlokoa liindastering tse sa tšoaneng moo ho sebelisoang li-alloys tsa koporo.
