Deformation ke taba e tloaelehileng ea ho tjheseletsa ha linate, moo likarolo tse cheselitsoeng li ka bang le liphetoho tse sa batleheng tsa sebopeho ka lebaka la lintlha tse fapaneng. Sengoliloeng sena se shebisisa mabaka a entseng hore ho be le deformation-induction deformation mme se fana ka tharollo e sebetsang ea ho fokotsa bothata bona.
- Mahlohonolo a Mocheso: E 'ngoe ea lisosa tse ka sehloohong tse bakang deformation ho tjheseletsa ha linate ke mocheso o mongata libakeng tse sebakeng sa heno nakong ea ts'ebetso ea ho cheselletsa. Mocheso ona o feteletseng o ka lebisa ho atolosoeng ha mocheso, ho fella ka ho phunya kapa ho kobeha ha workpiece.
- Mekhahlelo e sa tsitsang ea Welding: Mekhahlelo e sa nepahalang kapa e sa tsitsang ea welding, joalo ka ho chesella ho feteletseng hona joale kapa nako e telele ea welding, e ka kenya letsoho ho futhumatsang ho sa lekanang le ho senyeha ho latelang ha likarolo tse cheselitsoeng. Li-parameter tse lekantsoeng hantle li bohlokoa ho fihlela kabo e leka-lekaneng ea mocheso.
- Thepa ea thepa ea Workpiece: Lisebelisoa tse fapaneng li na le li-conductivity tse fapaneng tsa mocheso le li-coefficients tsa katoloso, tse ka susumetsang ts'oaetso ea tsona ea ho senyeha nakong ea welding. Ho kopanya lintho tse sa lumellaneng ho ka mpefatsa bothata ba deformation.
- Tlhophiso e sa Lekaneng: Ho lokisa ho se lekane kapa ho koala sekheo sa mosebetsi ho ka lebisa motsamaong o fetelletseng nakong ea welding, ho baka ho se tsamaisane hantle le deformation.
- Khatello e sa Lekaneng ea Welding: Kabo ea khatello e sa ts'oaneng nakong ea welding e ka baka maqhama a sa lekanang 'me a kenya letsoho ho deformation, haholo linthong tse tšesaane kapa tse bobebe.
- Residual Stress: Khatello ea masala e bakoang ke welding sebakeng se kopaneng le eona e ka kenya letsoho ho deformation. Likhatello tsena tsa ka hare li ka 'na tsa phomola ha nako e ntse e ea, tsa etsa hore mosebetsi o sothe kapa o sothe.
- Sekhahla sa ho Pholisa: Sekhahla sa ho pholisa ka tšohanyetso kapa se sa laoleheng ka mor'a ho cheselletsa ho ka baka ts'oaetso ea mocheso, e lebisang ho deformation sebakeng se cheselitsoeng.
Ho sebetsana le Deformation: Ho fokotsa deformation ho welding nut spot, ho ka etsoa mehato e mengata:
a. Optimize Welding Parameters: Beha ka hloko le ho laola li-parameter tsa welding, u nahane ka thepa ea thepa le tlhophiso e kopanetsoeng, ho finyella kabo e tšoanang ea mocheso.
b. Sebelisa Fixturing e Nepahetseng: Netefatsa hore lisebelisoa tsa mosebetsi li tsitsitse ka mokhoa o sireletsehileng 'me li hokahantsoe hantle nakong ea welding ho fokotsa motsamao le deformation.
c. Laola Khatello ea Welding: Boloka khatello ea welding e tsitsitseng le e loketseng ho finyella li-welds tse tšoanang le tse tsitsitseng.
d. Kalafo ea Preheat kapa Post-Heat: Nahana ka kalafo ea mocheso oa preheating kapa post-weld ho imolla khatello ea maikutlo e setseng le ho fokotsa kotsi ea deformation.
e. Controlled Cooling: Kenya ts'ebetsong mekhoa ea ho pholisa e laoloang ho thibela liphetoho tse potlakileng tsa mocheso le ho fokotsa ho senyeha.
Deformation in nut spot welding e ka amahanngoa le lintlha tse kang mocheso oa mocheso, li-parameter tsa welding tse sa lumellaneng, thepa ea thepa, fixturing, khatello ea welding, khatello e setseng le sekhahla sa ho pholisa. Ka ho utloisisa lisosa tsena le ho nka mehato e loketseng, joalo ka ho ntlafatsa li-parameter tsa welding, ho sebelisa fixturing e nepahetseng, le ho sebelisa pholiso e laoloang, basebelisi ba ka fokotsa mathata a deformation, ba hlahisa li-welds tsa boleng bo holimo tse nang le khopamo e nyane le ho fihlela sephetho se lakatsehang lits'ebetsong tse fapaneng.
