I-Resistance welding iyindlela esetshenziswa kabanzi embonini yokukhiqiza yokuhlanganisa izinsimbi. Incike ekusetshenzisweni kokushisa nengcindezi ukuze idale isibopho esiqinile phakathi kwezindawo ezimbili zensimbi. Ukulawulwa kwenqubo yokushisela kubalulekile ukuze kuqinisekiswe ukushiselwa kwekhwalithi ephezulu, futhi ithiyori yokulawula engaqondakali isivele njengethuluzi elinamandla ekufezeni lo mgomo.
Ithiyori yokulawula engaqondakali igatsha lobunjiniyela bokulawula elibhekene namasistimu lapho ukumodela okunembayo kuyinselele ngenxa yokuba khona kokungaqiniseki nokunganembile. Ekushiseleni ukumelana, izici ezahlukahlukene, njengokuhlukahluka kwezakhiwo ezibonakalayo, ukugqokwa kwama-electrode, nezimo zemvelo, zingathinta inqubo yokushisela. Ukulawula okungaqondakali kunikeza indlela eguquguqukayo neguquguqukayo yokuphatha lokhu kungaqiniseki.
Enye yezinzuzo ezibalulekile zokulawula okungaqondakali ku-resistance welding yikhono layo lokusingatha okuguquguqukayo kwezilimi. Ngokungafani namasistimu okulawula endabuko ancike kumanani acacile, amanani, ukulawula okungaqondakali kungasebenza nezincazelo zekhwalithi zokuhlukahluka. Isibonelo, esikhundleni sokucacisa indawo yokushisa enembile, isistimu yokulawula engaqondakali ingasebenzisa amagama olimi afana nokuthi "phansi," "maphakathi," noma "phezulu" ukuchaza izinga lokushisa elifunekayo. Le ndlela yokusetshenziswa kolimi inembile futhi ingathwebula ubuchwepheshe babasebenzisi abangabantu ngempumelelo.
Amasistimu okulawula angaqondakali ekushiseleni ukumelana ngokuvamile ahlanganisa izingxenye ezintathu eziyinhloko: i-fuzzifier, isisekelo somthetho, kanye ne-defuzzifier. I-fuzzifier iguqula idatha yokufaka esheshayo, efana nezinga lokushisa nezilinganiso zokucindezela, ibe okuguquguqukayo kolimi olungaqondakali. Isisekelo somthetho siqukethe isethi yemithetho ye-IF-THEN echaza ukuthi isistimu yokulawula kufanele iphendule kanjani ezinhlanganisela ezahlukene zokuguquguquka kokufaka. Isibonelo, uma izinga lokushisa "liphezulu" futhi ingcindezi "iphansi," bese ukwandisa amandla okushisela. Okokugcina, i-defuzzifier iguqula izenzo zokulawula ezingaqondakali zibuyele kumasiginali ahlanzekile angasetshenziswa emshinini wokushisela.
Amandla wangempela okulawula okungaqondakali asemandleni ako okuzivumelanisa nezimo ezishintshayo. Endaweni yokushisela ukumelana, izici ezifana nogqinsi lwezinto kanye nesimo se-electrode zingahluka kusuka kokushisela okukodwa kuya kwenye. Amasistimu okulawula angaqondakali angalungisa ngokuqhubekayo izenzo zawo zokulawula ngokusekelwe kumpendulo yesikhathi sangempela, azenze zilungele izinhlelo zokusebenza lapho ukumodela okunembile kunzima khona.
Sengiphetha, ithiyori yokulawula engacacile inikezela ngendlela eqinile futhi evumelana nezimo yokulawula imishini yokushisela. Ngokuvumela ukuguquguquka kwezilimi nokusingatha ukungaqiniseki ngomusa, amasistimu okulawula angaqondakali angathuthukisa ikhwalithi nokuthembeka kwamalunga ashiselwe embonini yokukhiqiza. Njengoba ubuchwepheshe buqhubeka buthuthuka, singalindela ukubona ezinye intuthuko kanye nokusetshenziswa kokulawula okungaqondakali ekushiseleni ukumelana nezinye izizinda lapho ukungaqiniseki kuyinselele khona.
