Uma uke wazama ukushisela ibha ye-aluminium engu-7075, cishe uyazi ukuthi akuqondile njengokusebenza namanye ama-alloys e-aluminium. Yaziwa ngamandla ayo aphezulu kanye nokumelana nokukhathala okuhle kakhulu, i-7075 aluminium iyinketho ethandwayo endaweni yezindiza, ezimotweni, nasezinhlelweni zokusebenza zobunjiniyela obusebenza kahle. Kodwa-ke, izakhiwo zayo eziyingqayizivele nazo zenza kube nzima kakhulu ukushisela. Ngakho-ke ochwepheshe baqinisekisa kanjani ukushisela okuhlanzekile, okuqinile kule alloy? Ake sihlukanise amathiphu namasu abalulekile ukuze kube yingcweti yenqubo.
Qonda i-alloy ngaphambi kokushaya i-arc
Ukhiye wokuqala wempumelelo kuIbha ye-aluminium engu-7075ukushisela ukuqonda ukwakheka kwengxubevange. I-7075 iyingxubevange ye-aluminium-zinc ekwazi ukumelana nokushisa ethola amandla ngokungezwa kwe-zinc, i-magnesium, nethusi. Ngeshwa, lokhu futhi kuyenza ibe bucayi kakhulu ekuqhekekeni ngesikhathi nangemva kokushisela. Ngokungafani ne-6061 noma amanye ama-alloys avumelana ne-weld, i-7075 ijwayele ukwenza izinhlanganisela ze-brittle intermetallic ezingafaka engozini ubuqotho be-weld.
Ngaphambi kokuthi uthathe ithoshi, kubalulekile ukuthi ucabangele ukuthi ukushisela kuyindlela engcono kakhulu yokujoyina noma uma ezinye izindlela ezifana nokubopha ngomshini noma i-adhesive bonding zingase ziveze imiphumela engcono.
Ukulungiselela: Iqhawe Elingasuliwe Lempumelelo Yokushisela
Ama-welds amakhulu aqala isikhathi eside ngaphambi kwenqubo ye-welding yangempela. Ukulungiselela kahle kubalulekile uma usebenza ne-7075 aluminium. Qala ngokuhlanza kahle indawo engaphezulu ukuze ususe noma yiziphi izendlalelo ze-oxide, uwoyela, noma ukungcola. Sebenzisa ibhulashi lensimbi engagqwali elakhelwe i-aluminium kuphela bese ulandelela nge-acetone ukuze unciphise amafutha.
Umklamo ohlangene ubaluleke ngokufanayo. Ngenxa yokuthi ukushiselwa kwebha ye-aluminium engu-7075 kunobungozi obukhulu bokuqhekeka, ukushisa kuqala insimbi phakathi kuka-300°F no-400°F (149°C kuya ku-204°C) kungasiza ekunciphiseni ukuthambekela okushisayo futhi kunciphise ithuba lokuphuka okubangelwa ingcindezi.
Isigcwalisi Esilungile Senza Wonke Umehluko
Esinye sezinqumo ezibaluleke kakhulu ekushiseleni i-aluminium 7075 ukukhetha insimbi yokugcwalisa efanele. Ngoba i-7075 ngokwayo ayishiseki ngomqondo wendabuko, ukusebenzisa isigcwalisi esihambisana kakhulu ne-weld kungavala igebe. Izinketho ezifana ne-5356 noma i-4047 aluminium fillers zivame ukukhethwa ukuze kuthuthukiswe i-ductility nokunciphisa ukuqhekeka endaweni yokushisela.
Kodwa-ke, khumbula ukuthi ukusebenzisa lawa ma-filler kunganciphisa kancane amandla okuhlangana uma kuqhathaniswa nesisekelo. Lokho kuwukuhweba onjiniyela abaningi abazimisele ukukwenza ukuze kukhule ukuqina nobuqotho.
I-TIG noma i-MIG? Khetha Inqubo Yokushisela Elungile
Ngokushisela ibha ye-aluminium engu-7075, ukushisela kwe-TIG (Tungsten Inert Gas) kuyathandwa kakhulu. Ivumela ukulawula okungcono kokufakwayo kokushisa futhi ikhiqize amashisela ahlanzekile, anembe kakhudlwana—lokho kanye okudingekayo lapho kusetshenzwa ngezinto ezishisayo ezinjalo.
Sekushiwo lokho, abashiseli abanolwazi abasebenzisa amasu athuthukile kanye nemishini bangase ngempumelelo i-MIG weld 7075 aluminium ezinhlelweni ezingabalulekile kangako. Kungakhathalekile ukuthi iyiphi indlela, ukuvikela okufanele ngegesi engu-100% ye-argon kubalulekile ukuvikela i-weld pool ekungcoleni.
Ukwelashwa Kokushisa Kwangemva Kwe-Weld Nokuhlolwa
Ukwelashwa kokushisa kwangemva kokushisela kungasiza ekunciphiseni izingcindezi ezinsalela futhi kubuyisele izici ezithile zokuwumshini. Kodwa-ke, ukushisa kabusha i-7075 aluminium kuyinkimbinkimbi futhi kufanele kwenziwe ngokucophelela ukugwema ukuhlanekezela noma ukuqhekeka okuqhubekayo. Izindlela zokuhlola ezingalimazi njengokuhlola ukungena kodayi noma ukuhlolwa kwe-X-ray ziyanconywa ukuze kuqinisekiswe ikhwalithi yokushisela.
Prakthiza, Ukubekezela, Nokunemba
Ibha ye-aluminium yokushisela i-7075 isivivinyo sekhono, isineke, nokulungiselela. Nakuba inqubo idinga kakhulu kunokushisela amanye ama-alloys, ukulandela lawa macebiso ochwepheshe kuzowandisa kakhulu amathuba akho okuzuza amalunga aqinile, aqinile.
Kungakhathaliseki ukuthi ungumshiseli ongumakad' ebona noma usanda kuqala uhambo lwakho ngama-alloys e-aluminium yamandla aphezulu, ukusebenzisa amasu afanele kwenza umehluko.
Ingabe Ukulungele Ukuphakamisa Imiklamo Yakho Yensimbi?
Ukuze uthole ulwazi olwengeziwe lochwepheshe kanye nokwesekwa kobuchwepheshe ekucutshungulweni kwe-aluminium nokushisela,Konke Kumelwe Ngeqinisoilapha ukuze ikusize ufinyelele ukunemba nokusebenza kuyo yonke iphrojekthi. Xhumana nathi namuhla ukuze ufunde kabanzi!
