Imishini yokushisela amabala aphakathi nendawo isetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yokusebenza kahle kwayo nokunemba.Kodwa-ke, ukuqinisekisa ikhwalithi ye-welding, kubalulekile ukugcina ibhalansi yokushisa ngesikhathi senqubo ye-welding.
Umshini we-intermediate frequency spot welding uqukethe i-transformer, i-electrode yokushisela, i-workpiece, isistimu yokupholisa, kanye nesistimu yokulawula.Ngesikhathi senqubo yokushisela, i-transformer ikhiqiza i-high-frequency current futhi iyihambise ku-electrode yokushisela.I-electrode ibe idlulisela i-current ku-workpiece, eyenza ukushisa futhi incibilikise into, yenze i-weld.
Ukugcina ibhalansi yokushisa kubalulekile ukuze kuqinisekiswe ukuzinza kwenqubo yokushisela.Ibhalansi ye-thermal ibhekisela esimweni lapho inani lokushisa elikhiqizwa inqubo yokushisela lilingana nenani lokushisa elichithwayo.Uma ukushisa okukhiqizwa kukhulu kunokushisa okuchithiwe, izinga lokushisa le-electrode kanye ne-workpiece lizokhula, okuholela ekuguquguqukeni nasekulinyazweni kwezinto.Uma ukushisa okulahliwe kukhulu kunokushisa okukhiqizwa, i-welding ingase ingakwazi ukwakha isibopho esiqinile.
Ukugcina ibhalansi yokushisa, umshini wokushisela indawo yefrikhwensi emaphakathi usebenzisa isistimu yokupholisa.Isistimu yokupholisa izungeza okokupholisa, njengamanzi noma uwoyela, nge-electrode kanye nesiqeshana somsebenzi ukuze kususwe ukushisa okukhulu.Isipholile sigeleza ku-electrode kanye nocezu lokusebenza, sidonsa ukushisa futhi sikususe, ngaleyo ndlela sivimbele izinga lokushisa ukuthi likhuphuke kakhulu.
Isistimu yokupholisa nayo idlala indima ebalulekile ekuqinisekiseni impilo yesevisi ye-electrode yokushisela.Phakathi nenqubo yokushisela, i-electrode ingaphansi kwamazinga okushisa aphezulu, angabangela ukuba ikhubaze futhi iqhekeke.Uhlelo lokupholisa lusiza ukugcina izinga lokushisa eliphansi futhi elizinzile, okwandisa impilo ye-electrode futhi kunciphisa isidingo sokushintshwa njalo.
Sengiphetha, ukugcina ibhalansi yokushisa kubalulekile ukuze umshini wokushisela we-frequency ophakathi nendawo uzuze imiphumela yekhwalithi ephezulu.Uhlelo lokupholisa luyingxenye ebalulekile yomshini, njengoba lusiza ukususa ukushisa okweqile, ukuvimbela ukulimala kwezinto, nokwandisa impilo ye-electrode.Ngokuqinisekisa ibhalansi eshisayo, umshini we-welding we-intermediate frequency spot welding ungenza kahle nangempumelelo, ulethe imiphumela yekhwalithi ephezulu.
