Eyamanje esetshenziswa emishinini yokushisela indawo ye-inverter ephakathi nendawo idlala indima ebalulekile ekunqumeni indawo yokushisisa.Lesi sihloko sihlola umthelela wamanje endaweni yokushisisa kanye nemithelela yayo yenqubo yokushisela.
Joule Heating:
Ekushiseleni indawo, i-current edlula ku-workpiece ikhiqiza ukushisa ngenxa yokumelana.Lesi simo, esaziwa ngokuthi ukushisa kwe-Joule, kubangela ukufudumeza kwendawo endaweni yokushisela.Ubukhulu bamanje buthinta ngokuqondile inani lokushisa okukhiqizwayo, okunquma ukukhuphuka kwezinga lokushisa kanye nobukhulu bendawo yokushisa.
Ukusabalalisa Ukushisa:
Ukusatshalaliswa kokushisa ngaphakathi kwendawo yokusebenza kuthonywa iphrofayili yamanje.Amaleveli amanje aphezulu aphumela kumphumela wokushisa ogxile kakhulu, okudala indawo yokushisisa encane neyasendaweni.Ngokuphambene, imisinga ephansi iholela endaweni yokushisa ebanzi.Ukukhethwa kwezinga elifanele lamanje kubalulekile ukuze kuzuzwe izici zokushisisa ezifiselekayo zokushisela indawo okuphumelelayo.
Ikhwalithi ye-Weld:
Izinga lamanje linomthelela oqondile kwikhwalithi ye-weld.Amanzi anganele angase abangele ukuhlangana okungaphelele namajoyinti abuthaka, kuyilapho amandla amaningi kakhulu angabangela ukuchitheka kwempahla, ukushiswa, kanye nokuguqulwa.Ukuthola ububanzi bamanje obulungile obunikeza ukushisa okwanele kokuhlanganisa okufanele ngaphandle kokubangela imiphumela elimazayo kubalulekile ukuze kuzuzwe ukushiselwa kwendawo kwekhwalithi ephezulu.
Ukulawula Ukushisa:
Ukulawula amandla amanje ngesikhathi sokushisela kubalulekile ukuze kugcinwe ukushisa okungaguquki kanye nokuzuza izici ezifiselekayo zokushisela.Imishini yesimanje ye-medium frequency inverter spot welding inikeza izici zokulawula zamanje ezinembile, ezivumela opharetha ukuthi balungise futhi baqaphe amazinga amanje kuyo yonke inqubo yokushisela.Lokhu kulawula kuvumela ukulungiswa kahle kwendawo yokushisisa, ukuqinisekisa imiphumela engaguquki nethembekile yokushisela.
Ukucatshangelwa kwezinto:
Izinto ezihlukene zine-resistivity kagesi ehlukahlukene, ethinta impendulo yazo ekushiseni okubangelwa manje.Izinto ezisetshenziswayo, njengethusi noma i-aluminium, zingadinga ama-currents aphezulu ukuze kuzuzwe ukushisa okwanele, kuyilapho izinto eziphikisayo, njengensimbi engagqwali noma izinsimbi eziqine kakhulu, zingase zikhiqize ukushisa okwengeziwe kumaza aphansi.Ukuqonda izakhiwo zikagesi zezinto ezishiselwe kubalulekile ekukhetheni amazinga afanelekile amanje.
Eyamanje esetshenziswa emishinini yokushisela indawo yokushisela imvamisa emaphakathi ithonya kakhulu indawo yokushisa futhi, ngenxa yalokho, ikhwalithi ye-weld.Ngokulawula ileveli yamanje, opharetha bangathuthukisa izici zokushisisa, baqinisekise ukuhlangana okufanele, futhi bagweme umonakalo omkhulu wezinto ezibonakalayo.Ukucatshangelwa njengokushisisa kwe-Joule, ukusatshalaliswa kokushisa, ikhwalithi ye-weld, ukulawula ukushisa, kanye nezakhiwo ezibonakalayo kudlala indima ebalulekile ekunqumeni imingcele yamanje efanelekile yokusebenza okuphumelelayo kokushisela indawo.Ukuqonda umthelela wamanje endaweni yokushisisa kubalulekile ekwenzeni inqubo ibe ngcono futhi kuzuzwe ukushiselwa kwamabala okuthembekile nokusezingeni eliphezulu.
