Spot welding ke mokhoa o sebelisoang haholo oa ho kopanya liindasteri tse fapaneng, ho kenyeletsoa tsa likoloi le tsa tlhahiso. Ka har'a li-welding tse mahareng tsa maqhubu a mahareng, boleng le ts'ebetso ea weld li angoa ke lintlha tse fapaneng, ho kenyelletsa le khatello ea maikutlo. Sengoliloeng sena se ikemiselitse ho lekola phello ea khatello ea maikutlo ho li-welds tsa matheba a mahareng a maqhubu a mahareng a li-inverter spot welding.
- Liphello tsa Khatello ea Maikutlo ho Spot Welds: Khatello ea maikutlo e ka ba le liphello tse ntle le tse mpe ho li-welds tsa sebaka. Ho utloisisa litlamorao tsena ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea welding le ho netefatsa bots'epehi ba manonyeletso a weld. Litšusumetso tsa bohlokoa tsa khatello ea maikutlo ho li-welds li kenyelletsa:
a. Matla a Kopanetsoeng: Kabo e nepahetseng ea khatello ea maikutlo ho li-welds tsa letheba li ka matlafatsa matla a kopaneng. Ha khatello ea kelello e ajoa ka ho lekana ho pholletsa le sebaka sa weld, e khothalletsa likamano tsa interatomic le ho eketsa bokhoni ba ho jara mojaro oa weld. Sena se fella ka motsoako o matla le o ka tšeptjoang haholoanyane.
b. Residual Stress: Nakong ea ts'ebetso ea welding, ho futhumala ka potlako le ho pholile ho baka katoloso ea mocheso le ho honyela, ho lebisang khatellong e setseng sebakeng sa li-welds. Khatello e feteletseng ea masala e ka ama thepa ea mochini oa weld, joalo ka ho fokotsa bophelo ba mokhathala le ho eketsa kotsi ea ho phatloha kapa ho sotha.
c. Khatello ea Maikutlo: Kabo e fosahetseng ea khatello ea maikutlo kapa mefokolo ea moralo e ka lebisa khatellong ea maikutlo lintlheng tse itseng ka har'a weld. Khatello ea kelello sebakeng sena e ka fokolisa weld mme ea etsa hore ho be bonolo ho hloleha tlas'a meroalo e kentsoeng.
d. Ho sotha: Ho khopama ho bakoang ke khatello ea maikutlo ke taba e atileng ho cheselleng matheba. Kabo ea khatello ea maikutlo ea asymmetric nakong ea welding e ka etsa hore lisebelisoa tsa mosebetsi li holofale kapa li sothe, 'me tsa ama ho nepahala le ho lekana ha sehlahisoa sa ho qetela.
- Ho Laola Khatello ea Maikutlo ho Spot Welding: Ho fokotsa litlamorao tse mpe tsa khatello ea maikutlo le ho netefatsa li-welds tsa boleng bo holimo, ho ka sebelisoa maano a 'maloa:
a. Mekhahlelo e Loketseng ea Welding: Ho ntlafatsa likarolo tsa welding, joalo ka hona joale, nako, le matla a elektrode, ho ka thusa ho fihlela kabo e leka-lekaneng ea khatello ea maikutlo. Ka ho khetha le ho laola liparamente tsena ka hloko, li-welders li ka fokotsa khatello ea maikutlo le ho ntlafatsa matla a weld.
b. Moralo o Kopanetsoeng: Lenonyeletso le hlophisitsoeng hantle le nang le geometry e nepahetseng le matlafatso li ka thusa ho tsamaisa khatello ea maikutlo ka mokhoa o ts'oanang ho pholletsa le sebaka sa weld. Sena se fokotsa khatello ea kelello 'me se ntlafatsa botšepehi bo akaretsang ba weld.
c. Kalafo ea Mocheso oa Pele le ka Mor'a Weld: Ho sebelisa mekhoa ea kalafo ea mocheso pele le ka morao ho weld, joalo ka ho fokotsa khatello ea maikutlo, ho ka thusa ho fokotsa khatello ea maikutlo le ho ntlafatsa thepa ea mochini oa li-welds.
d. Tlhahlobo ea Sebopeho: Ho etsa tlhahlobo ea sebopeho, joalo ka tlhahlobo ea lintlha tse fokolang, ho ka fana ka leseli mabapi le kabo ea khatello ea maikutlo le ho thusa ho tseba libaka tse ka bang teng khatellong ea maikutlo. Sena se thusa baenjiniere ho etsa liphetoho tsa moralo le ho ntlafatsa liparamente tsa welding ka nepo.
Khatello ea maikutlo e ama haholo ts'ebetso le boleng ba li-welds tsa mabala a mahareng a li-inverter spot welding. Ka ho utloisisa litlamorao tsa khatello ea maikutlo le ho sebelisa mekhoa e nepahetseng ea ho cheselletsa, menahano ea moralo o kopaneng, le maano a taolo ea khatello ea maikutlo, li-welders le lienjineri li ka ntlafatsa li-welds bakeng sa matla a ntlafalitsoeng, ho tšoarella le ho nepahala ha maemo. Taolo e sebetsang ea khatello ea maikutlo qetellong e lebisa ho li-welds tse tšepahalang le tsa boleng bo holimo tse fihlelang litlhoko tsa lits'ebetso tse fapaneng.
