Kenyelletso ea Teko e Senyehileng ka Mechini e Medium Frequency Inverter Spot Welding

Teko e senyang e bapala karolo ea bohlokoa ho lekola bots'epehi le matla a li-welds tse hlahisoang ke mechini ea welding ea maqhubu a mahareng. Ka ho beha lisampole tsa weld litekong tse laoloang, bahlahisi ba ka lekola boleng ba weld, ba tseba mefokolo e ka bang teng, mme ba netefatsa hore ba latela litekanyetso tsa indasteri. Sengoliloeng sena se fana ka kakaretso ea mekhoa ea liteko tse senyang tse sebelisoang hangata mecheng ea li-welding tse mahareng tsa frequency inverter spot.

1. Teko ea Tensile: Teko ea tensile ke mokhoa o sebelisoang haholo oa liteko tse senyang tse lekanyang matla le ho dutla ha li-welds. Tekong ena, sampole ea weld e tlas'a matla a ho hula axial ho fihlela ho hloleha ho etsahala. Matla a sebelisitsoeng le deformation e hlahisoang e rekotoa, e lumellang baenjiniere ho tseba maemo a kang matla a ho qetela, matla a tlhahiso le bolelele. Teko ea tensile e fana ka leseli la bohlokoa mabapi le thepa ea mochini le bokhoni ba ho jara thepa ea li-welds.
2. Teko ea Shear: Teko ea ho kuta e lekola khanyetso ea li-welds tsa matheba ho matla a sebelisoang ho bapa le sefofane sa weld. Tekong ena, sampole ea weld e beoa tlas'a mojaro o fapaneng ho fihlela ho robeha ho etsahala. Boima bo boholo bo ts'ehetsoeng ke weld bo bontša matla a eona a ho kuta. Teko ea ho kuta e thusa ho lekola khanyetso ea weld khahlanong le ho hloleha ha sefahleho, e leng ntho ea bohlokoa lits'ebetsong tseo ho tsona ho nang le meroalo ea ho kuta.
3. Teko ea Bend: Teko ea bend e lekola hore na cheld ductility le boleng ba fusion lipakeng tsa lisebelisoa tse kopaneng. Tekong ena, sampole ea weld e kobeha ka lehlakoreng le itseng ho etsa hore ho be le deformation ho latela axis ea weld. Mohlala o hlahlojoa bakeng sa mefokolo e kang mapetsong, ho haella ha fusion, kapa ho kena ho sa fellang. Teko ea bend e fana ka leseli mabapi le bokhoni ba weld ba ho mamella meroalo e kobehang le ho hanyetsa ha eona ho robeha ha brittle.
4. Tlhahlobo ea Macroscopic: Tlhahlobo ea macroscopic e kenyelletsa ho hlahloba ka mahlo karolo e ka holimo ea sebaka se cheselitsoeng ho lekola sebopeho sa sona sa kahare le boteng ba bofokoli. Tlhahlobo ena e ka senola matšoao a ho kopanngoa ho sa lokelang, li-void, mapetsong, kapa ho se phethahale hofe kapa hofe. E fana ka kutloisiso ea boemo bo boholo ba botšepehi ba weld mme e ka tataisa tlhahlobo kapa liteko tse ling.

Mekhoa ea liteko tse senyang, joalo ka tlhahlobo ea matla, tlhahlobo ea ho kuta, tlhahlobo ea bend, le tlhahlobo ea macroscopic, e bohlokoa bakeng sa ho lekola boleng le ts'ebetso ea li-welds tse hlahisoang ke mechini ea welding e mahareng. Liteko tsena li fana ka leseli la bohlokoa mabapi le thepa ea mochini, bokhoni ba ho jara moroalo, bots'epehi ba sefahleho, le ho utloahala ha sebopeho. Ka ho etsa liteko tse senyang ka botlalo, bahlahisi ba ka etsa bonnete ba hore li-welds tsa mabala li fihlela maemo a hlokahalang, li ntlafatsa ts'epahalo ea sehlahisoa, le ho boloka ts'epo ea bareki lits'ebetsong tse fapaneng.
