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.Ngamasu okushisela afanele, ithusi le-beryllium lingashiselwa lona ngokwalo, liye kwamanye ama-alloys ethusi, nasensimbi.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.
Ama-alloys e-Copper kulula ukuwafaka.
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, okwethulwa lapha njengomhlahlandlela kuphela, uchungechunge lwezivivinyo zokushisela lungasetshenziswa ukuze kutholwe izimo zokushisela ezifanele zohlelo ngalunye.
Ngenxa yokuthi izinto eziningi ezingcolisa indawo yokusebenza zinamandla okumelana nogesi, izindawo ezingaphezulu kufanele zihlanzwe njalo.
Ingaphezulu lizokhuphula izinga lokushisa lokusebenza kwe-electrode, linciphise impilo yethiphu ye-electrode, lenze indawo engaphezulu ingasebenziseki, futhi lenze insimbi.
Ukuchezuka endaweni yokushisela, kubangela ukushisela okungamanga noma izinsalela emalungeni ashiselwe.Ifilimu kawoyela emincane kakhulu noma i-corrosion inhibitor inamathiselwe phezulu, futhi ngokuvamile ayikho inkinga ngokushisela ukumelana.I-beryllium copper electroplated phezulu inezinkinga eziningi ekushiseleni.
abambalwa.
I-beryllium yethusi enezithambisi ezinganamafutha ngokweqile noma ezishaywayo noma ezigxiviza zingahlanzwa i-solvent.Uma ingaphezulu ligqwalile
Indawo egqwalile kakhulu noma ephathwa ngokushisa kancane i-oxidize, futhi 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.
