Inqubo yokushisela emishinini yokushisela indawo ye-inverter ephakathi nendawo inezigaba ezimbalwa ezihlukene ezibalulekile ukuze kuzuzwe ukushisela kwekhwalithi ephezulu. Ukuqonda lezi zigaba kubalulekile ekwandiseni imingcele yokushisela nokuqinisekisa imiphumela efiselekayo yokushisela. Kulesi sihloko, sizohlola izigaba ezahlukene ezihilelekile enqubweni yokushisela yemishini yokushisela indawo ye-medium-frequency inverter spot.
- Isigaba Sokulungiselela: Isigaba sokuqala senqubo yokushisela yisigaba sokulungiselela, lapho izinto zokusebenza ezizoshiselwa zihlanzwa kahle futhi zibekwe kahle. Lokhu kuhilela ukususa noma yikuphi ukungcola noma ama-oxide ezindaweni ezizohlanganiswa, ukuqinisekisa ukuqondana okufanele, nokuvikela izinto zokusebenza endaweni efanele. Ukulungiselela okwanele kubalulekile ukuze kuzuzwe ukushisela okuqinile nokungaguquguquki.
- Isigaba Se-Pre-Welding: Uma izinto zokusebenza sezilungisiwe, imingcele ye-welding isethwe ohlelweni lokulawula lomshini wokushisela we-medium-frequency inverter spot welding. Lokhu kuhlanganisa ukulungisa i-welding current, isikhathi, kanye nengcindezi ngokusekelwe kubukhulu bezinto ezibonakalayo, uhlobo, nezici zokushisela ezifiselekayo. Isigaba sangaphambi kwe-welding siqinisekisa ukuthi umshini usulungele ukuqalisa inqubo yokushisela.
- Isigaba sokushisela: Isigaba sokushisela inqubo yangempela yokuhlanganisa ama-workpieces ndawonye. Emishinini yokushisela indawo ye-inverter ye-medium-frequency, i-high-frequency current kagesi isetshenziswa kuma-electrode, okukhiqiza ukushisa ezindaweni zokuxhumana phakathi kwezinto zokusebenza. Ukushisa kuncibilikisa izindawo zensimbi, kwenze i-weld nugget. Isigaba sokushisela ngokuvamile silawulwa yimingcele emisiwe, okuhlanganisa isikhathi sokushisela, samanje, nokucindezela.
- Isigaba se-Post-Welding: Ngemva kwesigaba sokushisela, isigaba esifushane sokuthungatha siyalandela. Kulesi sigaba, i-welding current ivaliwe, futhi ingcindezi ikhishwa. Lokhu kuvumela i-weld nugget ukuthi iqine futhi iphole, iqinisekise ubuqotho namandla wejoyinti lokushisela. Ubude besigaba se-post-welding singahluka kuye ngokuthi impahla eshiselwe kanye nezinga lokupholisa elifunekayo.
- Isigaba Sokuhlola Nesokuqeda: Isigaba sokugcina sibandakanya ukuhlola i-weld joint ukuze kuqinisekiswe ikhwalithi yayo. Lokhu kungase kuhlanganise ukuhlola okubonakalayo, ukuhlola okungalimazi, noma ezinye izinyathelo zokulawula ikhwalithi ukuze kutholwe noma yikuphi ukonakala noma ukungapheleli. Uma i-weld idlula ukuhlolwa, izinqubo zokuqeda ezifana nokugaya, ukupholishwa, noma ukwelashwa okungaphezulu kungenziwa ukuze kuzuzwe ukubukeka okufunayo nokushelela.
Inqubo yokushisela emishinini yokushisela i-medium-frequency inverter spot welding ingahlukaniswa ngezigaba eziningana ezihlukene, okuhlanganisa ukulungiselela, ukushisela kwangaphambili, ukushisela, ukushisela ngemuva, kanye nezigaba zokuhlola/zokuqeda. Isigaba ngasinye sidlala indima ebalulekile ekuzuzeni amashisela ekhwalithi ephezulu ngamandla aphelele nobuqotho. Ngokuqonda kanye nokwenza kahle isigaba ngasinye, opharetha bangaqinisekisa imiphumela ye-welding engaguquki futhi enokwethenjelwa kuzicelo zokushisela indawo ye-inverter ye-medium-frequency.
