Ho robeha ha weld spot e ka ba taba e thata eo re ka kopanang le eona nakong ea ts'ebetso ea mochini oa ho cheselletsa linate. Botšepehi ba motsoako oa weld bo senyeha ha libaka tsa weld li hlōleha ho mamella meroalo e kentsoeng kapa khatello ea tikoloho. Sehloohong sena, re tla hlahloba lisosa tse tloaelehileng tsa ho robeha ha weld spot le ho fana ka tharollo e sebetsang ea ho rarolla bothata bona.
- Lisosa tsa ho robeha ha Weld Spot Fracture:
- Ho kenella ha Weld ho sa Lekaneng: Kenyelletso e sa lekaneng ea mocheso kapa khatello e sa lekaneng nakong ea welding e ka lebisa ho fusion e sa fellang, e leng se bakang libaka tse fokolang tsa weld tse atisang ho robeha.
- Ho se lumellane ha lintho tse bonahalang: Lisebelisoa tse sa lumellaneng tse nang le li-coefficients tse fapaneng tsa ho atolosa mocheso li ka baka khatello ea kelello le ho khothalletsa ho robeha ha sehokelo sa weld.
- Tšilafalo ea Electrode: Li-electrode tse silafetseng li ka kenya litšila ka har'a letamo la weld, tsa fokolisa thepa ea mochini oa manonyeletso le ho lebisa ho se sebetseng pele ho nako.
- Boholo le Sebopeho sa Weld Spot: Jiometry ea weld e sa nepahalang, joalo ka bophara bo feteletseng kapa sebopeho se sa tloaelehang, e ka baka khatello ea maikutlo le ho khothaletsa ho qala ha fracture.
- Liparamente tse Ntlafetseng tsa Welding: Ho ntlafatsa liparamente tsa welding ho bohlokoa ho sebetsana le ho robeha ha sebaka sa weld. Ho eketsa tjheseletsa hona jwale, kgatello ya eleketrode, le nako ya ho tjheseletsa ho ka ntlafatsa ho kenella le ho kopanngwa ha weld, ho bakang matheba a matla a weld.
- Khetho ea Lisebelisoa: Ho khetha lisebelisoa tse lumellanang tse nang le thepa e ts'oanang ea mochini le li-coefficients tsa katoloso ea mocheso ho ka fokotsa khatello ea maikutlo le ho ntlafatsa ts'epo e kopaneng ea weld.
- Tlhokomelo le Tlhoekiso ea Electrode: Tlhokomelo le tlhoekiso ea kamehla ea li-electrode li bohlokoa ho thibela tšilafalo nakong ea ho cheselletsa. Tlhokomelo e nepahetseng ea li-electrode e tiisa sebopeho se tsitsitseng le sa boleng bo phahameng ba weld spot.
- Moralo le Tlhahlobo ea Weld Spot: Moralo o nepahetseng oa libaka tsa weld, ho kenyeletsoa boholo le sebopeho, o ka thusa ho tsamaisa khatello ea maikutlo ka mokhoa o ts'oanang le ho fokotsa kotsi ea ho robeha. Ho feta moo, ho etsa tlhahlobo ea khafetsa le liteko tse sa senyeheng ho ka bona mefokolo e ka bang teng pele, ho lumella mehato ea ho lokisa ka nako.
- Kalafo ea Annealing le Post-Weld: Ho sebelisa litlhare tsa annealing kapa post-weld ho ka thusa ho imolla khatello ea maikutlo e setseng ka har'a motsoako oa weld, ho ntlafatsa ductility le ho hanyetsa ho robeha.
Thibelo ea ho robeha ha letheba la weld mochining oa ho cheselletsa linate ho hloka mokhoa o felletseng o kenyelletsang ho ntlafatsa maemo a ts'ebetso, ho khetha lisebelisoa tse lumellanang, ho boloka li-electrode, le ho kenya ts'ebetsong mehato e sebetsang ea taolo ea boleng. Ka ho rarolla lisosa tsa ho robeha ha weld spot fracture, bahlahisi ba ka etsa bonnete ba hore ho etsoa manonyeletso a matla le a ka tšeptjoang a weld, a kenya letsoho ts'ebetsong e akaretsang le polokeho ea likarolo tse cheselitsoeng liindastering tse fapaneng.
