I-Resistance spot welding iyinqubo yokujoyina esetshenziswa kabanzi ekukhiqizeni, eyaziwa ngokusebenza kahle kwayo nokwethembeka. Ukuze kuzuzwe ukushisela okuphumelelayo, izici ezintathu ezibalulekile zidlala indima ebalulekile kule nqubo: yamanje, isikhathi, nengcindezi.
- Okwamanje: Isici sokuqala, samanje, sibhekisela kumandla kagesi ahlinzekwa ekusebenzeni kwe-welding. Ku-resistance spot welding, ama-electrode amabili ahlanganisa ama-workpieces, bese kudlula amandla kagesi aphezulu kuzo. Lokhu kwamanje kudala ukushisa ngenxa yokumelana kukagesi kwezinto ezihlanganiswayo. Inani lamanje elisetshenzisiwe kufanele lilawulwe ngokucophelela, njengoba lithinta ngokuqondile izinga lokushisa lendawo yokushisela. Umthamo omningi kakhulu ungaholela ekushiseni ngokweqile nasekulimaleni, kuyilapho okuncane kakhulu kungabangela ukushisela okungaphelele.
- Isikhathi: Isici sesibili esibalulekile isikhathi, esihambisana nesikhathi sokugeleza kwamanje ezintweni zokusebenza. Isikhathi sokusetshenziswa kwamanje sinquma inani lokushisa okukhiqizwa futhi, ngenxa yalokho, ukujula kwe-weld. Ukusetshenziswa kwamanje okunesikhathi ngokunembile kuqinisekisa ukuthi izinto ezisetshenziswayo ziyancibilika futhi zihlangane kahle. Ubude besikhathi obufushane bungabangela ukushisela okubuthakathaka, kuyilapho isikhathi esiningi singabangela ukushisa okukhulu kanye nokulimala okungaba khona ezintweni.
- Ingcindezi: Okokugcina, ingcindezi ingamandla asetshenziswa ezintweni zokusebenza ngesikhathi sokushisela. Ingcindezi ibalulekile ukuqinisekisa ukuthintana okusondelene phakathi kwezinto ezihlanganiswayo. Ukucindezela okufanele kusiza ukuxosha ukungcola nama-oxide endaweni yokushisela, okuvumela ukushisela okuhlanzekile nokuqinile. Ukucindezela okunganele kungabangela izinga eliphansi lokushisela, kuyilapho ukucindezela ngokweqile kungaholela ekulimazeni noma ukubhobozwa kwezinto zokusebenza.
Sengiphetha, i-resistance spot welding incike ekulawuleni ngokucophelela kwamanje, isikhathi, nengcindezi ukuze kwakhiwe amalunga aqinile futhi anokwethenjelwa. Lezi zici ezintathu kufanele zilinganiswe ngokunembile ukuze zifane nezinto ezithile kanye nogqinsi olushiselwayo. Uma kwenziwa ngendlela efanele, i-resistance spot welding inikeza indlela ephumelelayo nephumelelayo yokuhlanganisa izinsimbi ezihlukahlukene, okwenza kube inqubo eyisisekelo ekukhiqizeni kwesimanje.
