I-Resistance spot welding iwuhlelo olubalulekile ezimbonini ezahlukahlukene, ezihlanganisa ezezimoto, i-aerospace, ne-electronics. Izinga lama-welds akhiqizwa umshini wokushisela indawo libaluleke kakhulu, njengoba lithinta ngokuqondile ubuqotho nokuphila isikhathi eside komkhiqizo wokugcina. Amapharamitha amaningana adlala indima ebalulekile ekunqumeni ikhwalithi yomshini wokushisela indawo yokumelana. Kulesi sihloko, sizohlola le mingcele nokubaluleka kwayo.
- I-Electrode Material kanye Nomumo:Ukukhethwa kwezinto ezibonakalayo ze-electrode kubalulekile. Ama-electrode e-Copper avame ukusetshenziswa ngenxa ye-conductivity yawo kagesi kanye ne-thermal conductivity. Ukuma kwama-electrode nakho kunendaba; kufanele yakhelwe ukusabalalisa ingcindezi futhi isebenze ngokulinganayo kuyo yonke indawo yokushisela.
- I-Electrode Force:Amandla asetshenziswa ama-electrode athinta ikhwalithi ye-weld. Amandla anganele angaholela ekushiseleni okubuthakathaka, kuyilapho amandla amaningi angalimaza izinto ezihlanganiswayo. Ukulungiswa okufanele kubalulekile ukuze kuzuzwe ukushisela okungaguquki, okusezingeni eliphezulu.
- I-Welding Yamanje:I-welding current iyipharamitha eyisisekelo. Inquma inani lokushisa elikhiqizwa ngesikhathi senqubo yokushisela. I-current kumele ikhethwe ngokucophelela ukuze ihambisane nezinto ezishiselwe kanye nokujula kokungena okufunayo.
- Isikhathi sokushisela:Isikhathi sokugeleza kwamanje kuma-electrode saziwa ngokuthi isikhathi sokushisela. Kufanele ilawulwe ngokunembile ukuze kuqinisekiswe ukuhlangana okufunwayo kwezinto ngaphandle kokubangela ukushisa ngokweqile noma ukushiswa.
- Ukuhlanzeka kwe-Electrode:Ama-electrode ahlanzekile abalulekile kuma-welds wekhwalithi. Ukungcola noma i-oxidation ezindaweni ze-electrode kungaholela ekushiseni okungahambisani nokunciphisa ukuqhutshwa kwe-conductivity. Ukunakekelwa njalo nokuhlanza kubalulekile.
- Ubukhulu Bezinto Nohlobo:Ubukhulu kanye nohlobo lwezinto ezishiselwe kuthonya imingcele yokushisela. Izinto eziwugqinsi ngokuvamile zidinga ama-welding currents aphezulu kanye nezikhathi zokushisela ezinde. Ukwengeza, izinto ezihlukene zingase zibe ne-conductivity ehlukahlukene kanye nezakhiwo zokukhipha ukushisa, okudinga ukulungiswa ukuze kuzuzwe ikhwalithi yokushisela efanele.
- Indawo yokushisela:Imvelo yokushisela, okuhlanganisa izici ezifana nezinga lokushisa elizungezile kanye nomswakama, ingathinta inqubo yokushisela. Izimo ezimbi kakhulu zingase zidinge ukulungiswa kumapharamitha wokushisela ukuze kugcinwe ikhwalithi engashintshi.
- Isistimu yokulawula nokuqapha:Ikhwalithi yesistimu yokulawula emshinini wokushisela ibalulekile. Kufanele inikeze ukulawula okunembile phezu kwamapharamitha wokushisela kanye nokuqapha kwesikhathi sangempela kwenqubo yokushisela ukuze kutholwe noma yikuphi ukuchezuka.
- Uhlelo Lokupholisa:Ukupholisa okwanele kwama-electrode kubalulekile ukuvimbela ukushisa ngokweqile nokugcina ikhwalithi ye-weld engaguquki ngesikhathi sokusebenza okuqhubekayo. Izinhlelo zokupholisa ezifanele zisiza ukwandisa isikhathi sokuphila sama-electrode.
- Ukulungiswa komshini wokushisela:Ukugcinwa njalo komshini wokushisela kuyadingeka ukuze kuqinisekiswe ukuthi zonke izingxenye, okuhlanganisa ama-electrode, izintambo, nezinhlelo zokulawula, zisesimweni esifanele. Noma ikuphi ukuguga kufanele kuqondiswe ngokushesha ukuze kuvinjelwe ukwehla kwekhwalithi yokushisela.
Sengiphetha, ikhwalithi yemishini yokushisela indawo yokumelana incike kumapharamitha ambalwa abalulekile. Abakhiqizi nabaqhubi kufanele bacabange ngokucophelela futhi balawule lezi zici ukuze bakhiqize amashisela ekhwalithi ephezulu ngokungaguquki. Ngokulungiselela izinto ze-electrode, amandla, zamanje, isikhathi, ukuhlanzeka, nezinye izinto eziguquguqukayo, izimboni zingaqinisekisa ukwethembeka nokuqina kwemikhiqizo yazo eshiselwe. Ukwengeza, ukutshala izimali ezinhlelweni ezithuthukisiwe zokulawula nokuqapha kanye nokubeka phambili ukunakekelwa kwemishini kuzoba nomthelela kwikhwalithi yonke nokusebenza kahle kwenqubo yokushisela indawo.
