Ukumelana nogesi kuyipharamitha ebalulekile emishinini yokushisela i-medium frequency inverter spot, njengoba inquma ikhono lezinto ezisetshenziswayo ukumelana nokugeleza kwamandla kagesi. Lesi sihloko sihlose ukuhlaziya umqondo wokumelana nogesi kanye nokubaluleka kwawo kumongo wemisebenzi ye-spot welding kusetshenziswa imishini ye-medium frequency inverter.
- Ukuqonda Ukungazweli Kagesi: Ukumelana nogesi, okuchazwa uphawu ρ (rho), kuyimpahla elinganisa ukumelana kwayo nokugeleza kwamandla kagesi. Kuchazwa njengesilinganiso senkambu kagesi esetshenziswa kuyo yonke into kuya kumphumela wamanje kagesi. Ukumelana kuvamise ukukalwa ngamayunithi we-ohm-meters (Ω·m) noma ohm-centimeters (Ω·cm).
- Ukubaluleka Kokumelana Nogesi Ku-Spot Welding: Emishinini yokushisela indawo yokushisela i-frequency inverter emaphakathi, ukuqonda ukumelana nogesi kwezinto zokusebenza kubalulekile ngezizathu ezimbalwa: a. Ukukhethwa Kwezinto Ezibalulekile: Izinto ezihlukile zinokuphikisana kukagesi okuhlukahlukene, okungaba nomthelela enqubweni yokushisela. Ukukhetha izinto ezinokumelana okuhambisanayo kuqinisekisa ukugeleza kwamanje okusebenzayo kanye nokukhiqiza ukushisa okulungile ngesikhathi sokushisela. b. I-Joule Heating: I-Spot Welding incike ekuguquleni amandla kagesi abe ukushisa ngokushisisa okuphikisayo. I-resistivity yezinto zokusebenza ze-workpiece inquma inani lokushisa elikhiqizwa endaweni yokushisela, kuthonya ngokuqondile ikhwalithi ye-weld namandla. c. Ukusabalalisa Ukushisa: Ukwehluka kokumelana nokumelana kungaholela ekusabalaliseni ukushisa okungajwayelekile ngesikhathi sokushisela indawo. Izinto ezikwazi ukumelana nezinga eliphezulu zingase zibonise ukushisisa okungalingani, okuthinta usayizi nokuma kwe-weld nugget futhi kungase kuphazamise ubuqotho obuhlangene. d. Ukumelana Nokuxhumana: Ukumelana nogesi kusixhumi esibonakalayo se-electrode-workpiece kuthonya ukumelana nokuxhumana. Ukumelana okuphezulu kungaholela ekwandeni kokumelana nokuxhumana, okuthinta ukudluliswa kwamanje kanye nokukhiqizwa kokushisa.
- Izinto Ezithinta Ukungazweli Kagesi: Izinto ezimbalwa zithonya ukumelana kukagesi kwezinto ezisetshenziswa ekushiseleni indawo: a. Ukubunjwa Kwezinto Ezibalulekile: Ukwakheka kwe-elementi nokuqukethwe okungahlanzekile kokubalulekile kuthinta kakhulu ukumelana kwayo. Izinto ezinamazinga aphezulu okungcola ngokuvamile zibonisa ukumelana okuphezulu. b. Izinga lokushisa: Ukumelana nogesi kuncike kumazinga okushisa, nezinto eziningi ezibonisa ukwenyuka kokumelana nezinga lokushisa njengoba izinga lokushisa likhuphuka. Ngakho-ke, kubalulekile ukucabangela izinga lokushisa lokusebenza ngesikhathi sokushisela ukuze uhlole ngokunembile imiphumela yokumelana nokumelana. c. Isakhiwo Sokusanhlamvu: Isakhiwo sokusanhlamvu kanye nokuhlelwa kwekristalu kwezinto kungathinta ukumelana kwazo nogesi. Izinto ezisanhlamvu ezicolekile ngokuvamile zibonisa ukumelana okuphansi kunezinto ezisanhlamvu. d. I-alloying Elements: Ukwengezwa kwezakhi ze-alloying kungashintsha ukumelana nogesi kwezinto. Ukwakheka okuhlukile kwe-alloy kungaholela emazingeni ahlukene okumelana, kube nomthelela kunqubo yokushisela.
Ukuqonda umqondo we-resistivity kagesi kanye nokubaluleka kwawo emishinini yokushisela i-medium frequency inverter spot kubalulekile ukuze kuzuzwe izinga eliphezulu lokushisela nokusebenza. Ngokucabangela ukumelana nogesi kwezinto zokusebenza, abakhiqizi bangakhetha izinto ezifanele, balawule ukusatshalaliswa kokushisa, banciphise ukumelana nokuxhumana, futhi baqinisekise ukugeleza kwamanje okusebenzayo ngesikhathi senqubo yokushisela. Lolu lwazi lwenza kube lula ukuklama nokusebenza kwezinhlelo zokushisela amabala, ekugcineni kuholele ekushiseleni okuthembekile nokusezingeni eliphezulu ezinhlelweni ezihlukene zezimboni.
