Insimbi engagqwalikuyinto esetshenziswa kabanzi eyaziwa ngokumelana nokugqwala okuhle kakhulu kanye nezakhiwo zemishini. I-Medium frequency inverter spot welding inikeza izinzuzo eziyingqayizivele ngokuya ngokunemba, ukulawula, ukushisela indawo kuyinqubo eyodwa yokushisela.ukumelana nokushisela, kanye nekhwalithi yokushisela yensimbi engagqwali. Kulesi sihloko, sizohlola inqubo nokucatshangelwa kwe-resistance spot welding steel stainless steel.
Ukukhethwa Kwempahla Nokulungiselela:Ukukhetha insimbi engagqwali efanele ngokusekelwe ezidingweni ezithile zokufaka isicelo kubalulekile ngaphambi kokuqala inqubo yokushisela. Insimbi engagqwali iqukethe izakhi ezihlukahlukene zengxubevange njenge-chromium, i-nickel, ne-molybdenum, ezisiza ekumelaneni nokugqwala nokushisela. Ukwengeza, indawo yokusebenza kufanele ihlanzwe kahle futhi ingabi nakungcola ukuze kuqinisekiswe ikhwalithi ephezulu yokushisela.
Ukukhethwa kwe-Electrode:Ukukhetha i-electrode kubalulekile lapho ushisela insimbi engagqwali. Kunconywa ukusebenzisa ama-electrode enziwe ngezinto ezihambisana nensimbi engagqwali, njenge-chromium zirconium yethusi noma ama-alloys ethusi. Lawa ma-electrode ahlinzeka ngokusebenza kahle kukagesi nokuzinza kokushisa, okuqinisekisa ukudluliswa kwamandla okuphumelelayo nokuphila isikhathi eside kwama-electrode.
Amapharamitha we-Welding:Ukuze ushise ngempumelelo insimbi engagqwali, kubalulekile ukulawula ngokunembile imingcele yokushisela. Izinto ezifana ne-welding current, isikhathi, nengcindezi zidinga ukuthuthukiswa ngokusekelwe ebangeni nokushuba kwensimbi engagqwali. Ngokuvamile, i-welding yamanje ephansi ikhethwa ukunciphisa okokufaka ukushisa futhi ivimbele ukuguquguquka ngenkathi iqinisekisa ukuhlanganiswa okufanele kwezinto. Ugqinsi oluhlukene lwamapuleti ensimbi engagqwali lungase ludinge imisinga ehlukene yokushisela nezikhathi. Ngakho-ke, udinga ukwazi imingcele ye-welding efanele yobuningi bensimbi engagqwali ngayinye. Ngezansi kunetafula lamapharamitha wokushisela we-spotless welding steel.

I-Shielding Gas:Ukushisela insimbi engagqwali ngokuvamile kudinga ukusetshenziswa kwegesi evikelayo ukuvikela indawo yokushisela ekungcolisweni nasekungcolisweni. Ukukhetha okuvamile kuyinhlanganisela ye-argon ne-helium, ehlinzeka nge-arc ezinzile futhi ivikele ngokuphumelelayo insimbi encibilikisiwe. Izinga lokugeleza kwegesi elivikelayo kufanele lilungiswe ukuze kuqinisekiswe ukumbozwa okwanele nokuvikelwa ngesikhathi senqubo yokushisela.
I-Welding Technique:Uma usebenzisaindawo yokushiselangensimbi engagqwali, indlela efanele yokushisela ibalulekile. Kunconywa ukusebenzisa uchungechunge lwe-welding pulses emifushane esikhundleni se-welding eqhubekayo ukuze unciphise ukufakwa kokushisa nokulawula i-weld pool. Ukwengeza, ukugcina ingcindezi engaguquki kuyo yonke inqubo yokushisela kusiza ukufeza amalunga aqinile futhi afanayo.
Ukwelashwa Kwangemva Kokushisa:Ngemva kokuqeda inqubo yokushisela, kubalulekile ukwenza ukwelashwa kwe-post-weld ukuqinisekisa ukuthi insimbi engagqwali ihlangabezana nezindinganiso zokusebenza ezidingekayo. Lokhu kungase kuhlanganise izinqubo ezinjengokudlula, ukukha, noma ukuthungatha, kuye ngebanga elithile lensimbi engagqwali kanye nezidingo zohlelo lokusebenza. Lezi zindlela zokwelapha zisiza ukubuyisela ukumelana nokugqwala futhi kuqede noma yiziphi izinkinga ezingase zibe khona zokuzwela ezibangelwa i-inqubo Welding.
Ukuhlolwa kwe-Post-Weld:Ukuze uqinisekise ukuthi amandla e-weld ahlangabezana nezindinganiso ezidingekayo, ukuhlolwa okulimazayo noma ukuhlolwa kwe-tensile ngokuvamile kwenziwa ngemva kokushisela. Ukuhlola okulimazayo kuhlola ngokubonakalayo ukuthi ingabe ijoyinti ye-weld ingene ngokugcwele kucezu lokusebenza. Uma ilunga liphuka kalula, i-weld ayiphumeleli. I-weld ephumelelayo izodabula isisekelo sensimbi ngaphandle kokuphula ilunga. Ukuhlolwa kwe-tensile kulinganisa ubukhulu bamandla obungaki amandla ijoyinti le-weld elingamelana nalo, kunikeza ukuhlolwa kochwepheshe ukuze kutholwe ukuthi liyahlangabezana yini nezicaciso ezidingekayo ngokusekelwe kumandla okuqina adingekayo ocezu lokusebenza.
I-Medium frequency inverter spot welding inikezela ngendlela esebenzayo yokushisela insimbi engagqwali, enikeza ukulawula okunembile, okokufaka okushisa okuncane, kanye nekhwalithi enhle kakhulu yokushisela. Ngokucabangela izici ezinjengokukhethwa kwezinto ezibonakalayo, ukukhetha kwe-electrode, imingcele yokushisela, igesi evikelayo, indlela yokushisela, nokwelashwa kwe-post-weld, abakhiqizi bangakwazi ukufeza ama-welds athembekile futhi ahlala isikhathi eside ekusetshenzisweni kwensimbi engagqwali. Ngezinzuzo zayo ezingokwemvelo, imishini yokushisela amabala aphakathi nendawo ingamathuluzi abalulekile ezimbonini ezifana nezezimoto, ezokwakha, nokucubungula ukudla, lapho ukumelana nokugqwala nobuqotho bemishini kubalulekile.
Niniwenauseindawo yokushisela yokushisela insimbi engagqwali, le mininingwane engenhla kufanele ibe wusizo. Ukwengeza, ukukhetha i-stainless steel spot welder yekhwalithi ephezulu nakho kuyisici esibalulekile.
