Ukumelana nokuxhumana kudlala indima ebalulekile enqubweni yokukhiqiza ukushisa emshinini wokushisela we-medium frequency inverter spot.Ukuqonda ukuthi ukushisa kukhiqizwa kanjani ngokumelana nokuthintana kubalulekile ukuze kuthuthukiswe inqubo yokushisela kanye nokuzuza ukushisela kwekhwalithi ephezulu.Lesi sihloko sinikeza ukubuka kabanzi kwezinqubo ezihilelekile ekukhiqizeni ukushisa ngokusebenzisa ukumelana nokuxhumana emishini yokushisela i-medium frequency inverter spot.
- Ukumelana Nokuxhumana: Ukumelana nokuxhumana kwenzeka esibonakalayo phakathi kwama-electrode nezinto zokusebenza ngesikhathi sokushisela.Kubangelwa ukuthintana okungaphelele phakathi kwamathiphu e-electrode kanye nezindawo zokusebenza.Ukumelana nokuxhumana kuncike ezicini ezihlukahlukene, okuhlanganisa ukuhwaqeka kwendawo, ukuhlanzeka, ingcindezi esetshenzisiwe, kanye nokuhamba kukagesi kwezinto.
- I-Joule Heating: Uma amandla kagesi edlula endaweni yokuxhumana enokumelana, kubangela ukushisa kwe-Joule.Ngokomthetho we-Ohm, ukushisa okukhiqizwayo kuhambisana nesikwele samanje kanye nokumelana nokuxhumana.Ukuphakama kwamanje nokumelana nokuxhumana, kukhiqizwa ukushisa okwengeziwe.
- Ukusabalalisa Ukushisa: Ukushisa okukhiqizwa ngenxa yokumelana nokuthintana ngokuyinhloko kugxilwe kusixhumi esibonakalayo sokuxhumana phakathi kwama-electrode nama-workpieces.Ukushisa kwendawo kubangela ukuthi izinga lokushisa likhuphuke endaweni eseduze yendawo yokuxhumana, okuholela ekwakhekeni kwe-nugget encibilikisiwe kanye nokuhlanganiswa okulandelayo kwezinto zokusebenza.
- I-Thermal Conductivity: Ukushisa okukhiqiziwe kudluliselwa kusuka kusixhumi esibonakalayo sokuxhumana kuya ezintweni ezizungezile ngokusebenzisa i-thermal conduction.I-thermal conductivity ye-workpieces idlala indima ebalulekile ekusabalaliseni nasekukhipheni ukushisa.Ukudluliswa kokushisa okuphumelelayo kuqinisekisa ukuhlangana okufanele futhi kunciphisa ubungozi bokulimala kokushisa ezindaweni ezizungezile.
- Ukulawula Ukushisa: Ukulawula ukushisa okukhiqizwa ngokumelana nokuxhumana kubalulekile ukuze kuzuzwe ukushiselwa okungaguquki nokuphezulu.Okokufaka kokushisa kungalungiswa ngokulawula imingcele yokushisela njenge-welding yamanje, isikhathi se-welding, amandla e-electrode, nezinto ze-electrode.Ukulungiselela lezi zinhlaka kusiza ekulawuleni ukukhiqizwa kokushisa, ukuvimbela ukushisa ngokweqile noma ukushisa okwanele.
Ukukhiqizwa kokushisa ngokumelana nokuxhumana kuyisici esibalulekile senqubo yokushisela emishinini yokushisela i-medium frequency inverter spot.Ukumelana nokuxhumana, okuthonywa yizici ezifana nezimo ezingaphezulu nokucindezela okusetshenzisiwe, kuholela ekushiseni kwe-Joule kusixhumi esibonakalayo phakathi kwama-electrode nezinto zokusebenza.Ukushisa kugxile endaweni yokuxhumana, okuholela ekuncibilikeni kwendawo kanye nokuhlangana.Ukulawula ukushisa okufanelekile ngamapharamitha we-welding alungiselelwe kuqinisekisa ukukhiqizwa kokushisa okwanele kokushisela ngaphandle kokudala umonakalo omkhulu wokushisa.Ukuqonda izindlela ezihilelekile ekukhiqizeni ukushisa ngokusebenzisa ukumelana nokuxhumana kusiza ekuthuthukiseni inqubo yokushisela kanye nokufeza ama-welds athembekile nasezingeni eliphezulu ezinhlelweni ezihlukahlukene.
