I-Resistance welding iyindlela ethembekile, engabizi kakhulu, futhi ephumelelayo yokuhlanganisa unomphela izingcezu ezimbili noma ngaphezulu zensimbi ndawonye.Nakuba ukumelana nokushisela kuyinqubo yokushisela, ayikho insimbi yokugcwalisa, ayikho igesi yokushisela.Ayikho insimbi eyeqile okufanele isuswe ngemva kokushisela.Le ndlela ilungele ukukhiqizwa ngobuningi.Ama-welds aqinile futhi awabonakali.
Ngokomlando, i-resistance welding isetshenziswe ngempumelelo ukuhlanganisa izinsimbi eziqinile ezifana nensimbi ne-nickel alloys.I-conductivity ephakeme kagesi kanye ne-thermal ye-alloys yethusi yenza ukushisela kube nzima kakhulu, kodwa imishini yokushisela evamile ngokuvamile ine-alloy inekhwalithi enhle yokushisela egcwele.I-Beryllium yethusi ingashiselwa yona ngokwayo, kwamanye ama-alloys ethusi, kanye nensimbi.Ama-alloys ethusi angaphansi kuka-1.00mm ubukhulu ngokuvamile kulula ukuwathengisa.
Izinqubo ze-resistance welding ezivame ukusetshenziselwa ukushisela izingxenye zethusi ze-beryllium, i-spot welding kanye ne-projection welding.Ubukhulu be-workpiece, i-alloy material, okokusebenza okusetshenzisiwe kanye nesimo esingaphezulu esidingekayo sinquma ukufaneleka kwenqubo efanele.Ezinye izindlela zokushisela ezivame ukusetshenziswa ezisetshenziswa kakhulu, njengokushisela i-flame, i-butt welding, i-seam welding, njll., ayijwayele ukusetshenziselwa ama-alloys ethusi futhi ngeke kuxoxwe ngayo.
Izihluthulelo ze-resistance welding zamanje, ingcindezi kanye nesikhathi.Ukwakhiwa kwama-electrode kanye nokukhethwa kwezinto ze-electrode kubaluleke kakhulu ukuqinisekisa ikhwalithi yokushisela.Njengoba kunezincwadi eziningi ezimayelana nokushisela insimbi, izidingo ezimbalwa zokushisela ithusi le-beryllium ezivezwe lapha zibhekisela ekushunyeni okufanayo.I-Resistance welding akuyona neze isayensi enembile, futhi imishini yokushisela nezinqubo zinomthelela omkhulu kwikhwalithi yokushisela.Ngakho-ke, ulwazi olwethulwe lapha luyinkomba kuphela
ENingizimu, uchungechunge lokuhlolwa kwe-welding lunganquma izimo zokushisela ezifanele zohlelo ngalunye.
Ngenxa yokuthi izinto eziningi ezingcolisa indawo yokusebenza zinokumelana nogesi okuphezulu, indawo engaphezulu kufanele ihlanzwe njalo.Izindawo ezingcolile zingakhuphula izinga lokushisa lokusebenza kwe-electrode, zinciphise ukuphila kwethiphu ye-electrode, zenze indawo engaphezulu ingasebenziseki, futhi ibangele ukuba insimbi iphambuke endaweni yokushisela.bangela i-soldering noma i-slag.Ifilimu kawoyela elincanyana kakhulu noma isilondolozi sinamathiselwe phezulu, ngokuvamile esingenayo inkinga nge-resistance welding, futhi i-beryllium yethusi i-electroplated phezulu inezinkinga ezincane kakhulu ekushiseleni.Ithusi le-beryllium elinezithambisi ezohlisiwe ngokweqile noma ezishaywayo noma ezigxivizwayo zingahlanzwa i-solvent.Uma ingaphezulu ligqwalile kakhulu noma ingaphezulu lifakwe i-oxidized ngokwelashwa kokushisa okuncane, idinga ukugezwa ukuze kukhishwe i-oxide.Ngokungafani ne-copper oxide ebonakala kakhulu ngokubomvu-nsundu
Ngesikhathi esifanayo, i-beryllium oxide ebonakalayo endaweni ye-strip (ekhiqizwe ukwelashwa okushisa ku-inert noma ukunciphisa igesi) kunzima ukuyibona, kodwa kufanele futhi isuswe ngaphambi kokushisela.
