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 Sesebediswa sa Mosebetsi: 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.Mathata ana a ka hare a ka 'na a phomola ha nako e ntse e ea, a 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.
