I-Resistance spot welding iyinqubo yokushisela eguquguqukayo esetshenziswa ezimbonini eziningi ukujoyina izingxenye zensimbi ngempumelelo.Izinga lokushisela kwamabala lincike ezintweni eziningana, futhi ipharamitha eyodwa ebalulekile ingcindezi esetshenziswa kuma-electrode wokushisela.Kulesi sihloko, sizohlola ithonya elibalulekile lokucindezela ekusebenzeni kwe-electrode emishinini yokushisela indawo yokumelana.
1. Electrode Contact Area
Ukucindezela okusetshenziselwa ama-electrode okushisela kuthinta ngokuqondile indawo yokuxhumana phakathi kwama-electrodes kanye ne-workpiece.Ukucindezela okuphezulu kubangela indawo enkulu yokuxhumana.Le ndawo yokuxhumana ekhulayo yenza kube ngcono ukuqhutshwa kukagesi, okuholela ekuthuthukisweni kwekhwalithi yokushisela.Iqinisekisa ukuthi i-current igeleza ngokulinganayo kucezu lokusebenza, ikhuthaza ukuhlangana okungaguquki nokuqinile.
2. Isizukulwane Sokushisa
Ingcindezi idlala indima ebalulekile ekulawuleni ukushisa okukhiqizwa ngesikhathi senqubo yokushisela.Lapho ama-electrode efaka ukucindezela ku-workpiece, ukumelana phakathi kwawo kudala ukushisa.Ubukhulu bengcindezi buthonya izinga lokukhiqiza ukushisa.Ukucindezela okuphezulu kungaveza ukushisa okwengeziwe, okubalulekile ukuze kuzuzwe ukuxutshwa kwe-weld okufanele ezintweni eziwugqinsi noma izimo eziyinselele zokushisela.
3. Ukuguqulwa Kwezinto Ezibalulekile
Ingcindezi esetshenziswa ama-electrode ingabangela ukuguqulwa kwezinto endaweni yokusebenza.Lokhu kuguqulwa kubaluleke kakhulu ezintweni ezinemihlobiso engaphezulu noma ukungcola.Ngokusebenzisa ingcindezi eyanele, ama-electrode angadabula izendlalelo ezingaphezulu, aqinisekise isixhumi esibonakalayo sokushisela esihlanzekile nesingenakungcola.Lokhu kubangela ama-weld anamandla futhi athembekile.
4. Electrode Wear
Nakuba ingcindezi ibalulekile ekudaleni ama-welds ekhwalithi ephezulu, ingaba nomthelela ekugqokeni kwe-electrode.Ukucindezela okweqile kungaholela ekugqokeni kwama-electrode okusheshayo, kunciphise isikhathi sabo sokuphila.Ukucindezela okulingana kahle kuyadingeka ukuze kuzuzwe ikhwalithi ye-weld engaguquki ngenkathi unciphisa ukugqokwa kwama-electrode.Amanye ama-electrode enzelwe ukumelana nezingcindezi eziphakeme futhi afaneleka kakhulu izinhlelo zokusebenza ezithile.
5. Izinhlelo Zokulawula Ingcindezi
Imishini yesimanje yokushisela indawo yokumelana ivamise ukufaka izinhlelo ezisezingeni eliphezulu zokulawula ingcindezi.Lezi zinhlelo zivumela opharetha ukuthi balawule ngokunembile futhi baqaphe ingcindezi esetshenziswa kuma-electrode.Ngokugcina izinga lokucindezela elilungile kuyo yonke inqubo yokushisela, lezi zinhlelo zifaka isandla kwikhwalithi yokushisela engaguquki futhi andise ukuphila kwama-electrode.
6. Izinguquko Zengcindezi
Kwezinye izinhlelo zokusebenza zokushisela, ukuhlukahluka kokucindezela kungase kudingeke ukuze kubhekwane nezinselele ezithile.Isibonelo, lapho ushisela izinto ezihlukene noma izinto ezinobukhulu obuhlukahlukene, ukulungisa amazinga okucindezela kungasiza ukufeza ukushisela okufanayo.Ukushintsha ingcindezi kungase futhi kusetshenziselwe ukulawula okokufaka ukushisa nokuvimbela ukuhlanekezela kwezinye izinhlelo zokusebenza.
7. Ukuqinisekisa Ikhwalithi
Ukulawula ukucindezela kuyisici esibalulekile sokuqinisekisa ikhwalithi ekushiseleleni indawo yokumelana.Abakhiqizi kufanele basungule futhi bagcine izilungiselelo ezifanele zengcindezi ukuze bahlangabezane nezindinganiso zokushisela kanye nokucaciswayo.Ukuhlolwa ngezikhathi ezithile kanye nokulinganiswa kwezinhlelo zokulawula ingcindezi kubalulekile ukuze kuqinisekiswe ukuthi amazinga okucindezela afiswayo afinyelelwa ngokuqhubekayo.
Sengiphetha, ingcindezi iyipharamitha eyisisekelo emishinini yokushisela indawo yokumelana ethinta kakhulu ukusebenza kwe-electrode kanye nekhwalithi yokushisela.Ukucindezela okulawulwa kahle kuqinisekisa ukuthintana kwama-electrode okulungile, ukukhiqiza ukushisa okusebenzayo, ukuwohloka kwezinto ezibonakalayo, futhi kunciphisa ukugqokwa kwama-electrode.Izinhlelo ezithuthukisiwe zokulawula ukucindezela zithuthukisa ukunemba nokuvumelana kokushisela kwamabala, okuwenza abe ingxenye ebalulekile yobuchwepheshe besimanje bokushisela.
