I-Resistance spot welding iyindlela esetshenziswa kakhulu ezinqubweni zokukhiqiza, ikakhulukazi ezimbonini zezimoto nezasemoyeni. Le ndlela ihilela ukuhlanganisa izingcezu ezimbili zensimbi ndawonye ngokusebenzisa ukushisa nokucindezela ngokusebenzisa ama-electrode. Ipharamitha eyodwa ebalulekile kule nqubo ingcindezi ye-electrode. Kulesi sihloko, sizohlola ukubaluleka kwengcindezi ye-electrode emishinini yokushisela indawo yokumelana kanye nomthelela wayo kwikhwalithi yama-welds.
Ukuqonda I-Electrode Pressure
I-Electrode pressure, eyaziwa nangokuthi i-welding force noma i-contact pressure, ibhekisela kumandla asetshenziswa ama-electrode okushisela ezintweni zokusebenza ezihlanganiswayo. Le ngcindezi idlala indima ebalulekile ekuqinisekiseni ukushisela okuphumelelayo. Imisebenzi eyinhloko yokucindezela kwe-electrode yilezi:
1. Ukuqinisekisa Ukuthintana Kagesi Okuhle
Ukuze uthole ukushisela okusebenzayo kwendawo yokumelana, kufanele kube khona indlela kagesi engamelani kancane phakathi kwama-electrode nezinto zokusebenza. Ukucindezela okwanele kuqinisekisa ukuthintana okuhle kukagesi, kunciphisa ukumelana nogesi futhi kuvumela ukugeleza kwe-welding yamanje ngokuhlanganyela. Lokhu, futhi, kusiza ukukhiqizwa kokushisa okudingekayo kwinqubo yokushisela.
2. Ukukhuthaza Ukuguqulwa Kwezinto Ezibalulekile
Ukucindezela okwenziwa ama-electrode kubangela ukuwohloka kwendawo endaweni yokusebenza. Lokhu kuguqulwa kudala ukuxhumana okusondelene phakathi kwezinto zokusebenza ezimbili, kuthuthukisa isibopho se-metallurgical ngesikhathi sokushisela. Kuyasiza futhi ekwephuleni ukungcola okungaphezulu njengama-oxide nama-coatings, kuthuthuke ikhwalithi yokushisela.
3. Ukulawula Heat Generation
Ukucindezela okufanele kwe-electrode kusiza ukulawula inani lokushisa elikhiqizwa ngesikhathi sokushisela. Ukucindezela okwedlulele kungaholela ekushiseni ngokweqile, kuyilapho ukucindezela okunganele kungase kubangele ukukhiqizwa kokushisa okunganele. Ukuthola ibhalansi efanele kubalulekile ukuvimbela ukulimala kwezinto zokusebenza futhi uqinisekise ukushisela okuqinile.
Optimal Electrode Pressure
Ukunquma ingcindezi ye-electrode elungile kuncike ezintweni ezahlukahlukene, kufaka phakathi impahla eshiselwe, ukushuba kwayo, kanye namandla okushisela. Abakhiqizi bavame ukunikeza imihlahlandlela kanye nokucaciswa kwengcindezi ye-electrode ngokusekelwe kulezi zici. Ukwengeza, opharetha be-weld bangaqapha futhi balungise ukucindezela kwe-electrode ukuze bafinyelele ikhwalithi ye-weld oyifunayo.
Umthelela Kukhwalithi Ye-Weld
Ukucindezela kwe-electrode okunganele kungaholela ekushiyekeni kwe-welding okuningana, njengokuhlangana okungaphelele, i-porosity, namabhondi e-weld abuthakathaka. Ngakolunye uhlangothi, ukucindezela okukhulu kungaholela ekushiseleni ngokweqile, kubangele ukuwohloka nokulimala kwezinto zokusebenza. Ngakho-ke, ukugcina ingcindezi efanele ye-electrode kubalulekile ekukhiqizeni ama-welds asezingeni eliphezulu anezakhiwo ezifiselekayo zemishini.
Emishinini yokushisela indawo yokumelana, ingcindezi ye-electrode iyipharamitha eyinhloko ethonya kakhulu izinga lokushisela. Iqinisekisa ukuthintana kahle kukagesi, ikhuthaza ukuguqulwa kwezinto, futhi ilawula ukukhiqizwa kokushisa. Ukuze uthole imiphumela emihle, kubalulekile ukuqonda okokusebenza okushiselwayo futhi ulandele imihlahlandlela enconyiwe yokucindezela kwama-electrode. Ukulawulwa okufanele kwengcindezi ye-electrode ngeke nje kuthuthukise ikhwalithi yokushisela kodwa futhi kufake isandla ekusebenzeni kahle nokuthembeka kwenqubo yokushisela.
