Ukuba ukhe wazama i-7075 ye-aluminium bar welding, mhlawumbi uyazi ukuba ayilulanga njengokusebenza nezinye iialloyi ze-aluminium. Eyaziwa ngamandla ayo aphezulu kunye nokumelana nokudinwa okugqwesileyo, i-7075 i-aluminium lukhetho oludumileyo kwi-aerospace, i-automotive, kunye ne-high-performance engineering applications. Nangona kunjalo, iipropathi zayo ezizodwa zikwakwenza kube nzima kakhulu ukuwelda. Ke iingcali ziqinisekisa njani iiwelds ezicocekileyo, ezomeleleyo kule alloy? Makhe sicazulule iingcebiso ezibalulekileyo kunye namaqhinga ukuze siphumelele inkqubo.
Qonda iAlloy ngaphambi kokubetha iArc
Isitshixo sokuqala kwimpumelelo kwi7075 ibha yealuminiyamukuwelda kukuqonda ukubunjwa kwengxubevange. I-7075 yi-alloy ye-aluminiyam-zinc ephathwa ngobushushu efumana amandla ayo ekongezwa kwe-zinc, i-magnesium kunye nobhedu. Ngelishwa, oku kuyenza ichaphazeleke kakhulu ngokuqhekeka ngexesha nasemva kwewelding. Ngokungafaniyo ne-6061 okanye ezinye ii-alloys ezinobuhlobo, i-7075 ithande ukwenza i-brittle intermetallic compounds ezinokubeka esichengeni ingqibelelo ye-weld.
Ngaphambi kokuba uthathe itotshi, kubalulekile ukuqwalasela ukuba i-welding yeyona ndlela ilungileyo yokujoyina okanye ukuba ezinye iindlela ezifana nokuqhoboshela ngoomatshini okanye ukuncamathela okuncamathelayo kunokuvelisa iziphumo ezingcono.
Ukulungiselela: Iqhawe elingagungqiyo leMpumelelo yeWelding
Iiwelds ezinkulu ziqala ixesha elide ngaphambi kwenkqubo yewelding. Ukulungiswa okufanelekileyo kubalulekile xa usebenza nge-7075 aluminium. Qala ngokucoca ngokucokisekileyo umphezulu ukususa naziphi na iileya zeoksidi, ioyile, okanye izingcolisi. Sebenzisa ibrashi yocingo engenastainless eyenzelwe ialuminiyam kuphela kwaye ulandele nge-acetone ukuthoba.
Uyilo oludibeneyo lubaluleke ngokulinganayo. Ngenxa yokuba i-7075 ye-aluminium bar welding inomngcipheko omkhulu wokuqhekeka, ukutshisa isinyithi phakathi kwe-300 ° F kunye ne-400 ° F (149 ° C ukuya kwi-204 ° C) kunokunceda ukunciphisa i-gradients ezishisayo kunye nokunciphisa ithuba lokuphuka kwe-stress-induced fractures.
Isigcwalisi Sasekunene Senza Wonke Umahluko
Esinye sezona zigqibo zibalulekileyo kwi-welding 7075 aluminiyam kukukhetha isinyithi esifanelekileyo sokuzalisa. Ngenxa yokuba i-7075 ngokwayo ayidityaniswanga ngokwengqiqo yemveli, ukusebenzisa isigcwalisi esihambelana kakhulu ne-weld sinokuvala umsantsa. Izinketho ezifana ne-5356 okanye i-4047 i-aluminium fillers zihlala zikhethwa ukuphucula i-ductility kunye nokunciphisa ukuqhekeka kwi-weld zone.
Nangona kunjalo, khumbula ukuba ukusebenzisa ezi zihluzi kunokunciphisa kancinane amandla okudibanisa xa kuthelekiswa nezinto ezisisiseko. Olu lurhwebo lweenjineli ezininzi ezizimisele ukwenza ukonyuka kokuqina kunye nemfezeko.
TIG okanye MIG? Khetha iNkqubo yokuWelding eLungileyo
Kwi-7075 ye-aluminium bar welding, i-TIG (i-Tungsten Inert Gas) i-welding ikhethwa ngokuqhelekileyo. Ivumela ulawulo olungcono kwigalelo lobushushu kwaye ivelise i-welds ecocekileyo, echanekileyo ngakumbi-kanye into efunekayo xa usebenza ngemathiriyeli yobushushu obunjalo.
Oko kwathiwa, abashiseli abanamava abasebenzisa iindlela eziphambili kunye nezixhobo banokuphumelela i-MIG weld 7075 aluminium kwizicelo ezingabalulekanga kangako. Nokuba yeyiphi na indlela, ukukhusela okufanelekileyo nge-100% yegesi ye-argon kubalulekile ukukhusela i-weld pool ekungcoleni.
Unyango lwe-Post-Weld Heat kunye noHlolo
Unyango lobushushu be-post-weld lunokunceda ukunciphisa uxinzelelo olushiyekileyo kunye nokubuyisela ezinye iimpawu zoomatshini. Nangona kunjalo, ukutshisa kwakhona ukutshisa i-7075 i-aluminiyam iyinkimbinkimbi kwaye kufuneka yenziwe ngononophelo ukuphepha ukugqwesa okanye ukuqhekeka ngakumbi. Iindlela zovavanyo ezingonakalisi ezifana nokuhlolwa kwedayi yokungena okanye uvavanyo lweX-reyi ziyacetyiswa ukuqinisekisa umgangatho we-weld.
Ziqhelise, Umonde, kunye Nokuchaneka
I-Welding 7075 ibha ye-aluminium luvavanyo lobuchule, umonde, kunye nokulungiselela. Ngelixa inkqubo ifuna ngokungenakuphikiswa kune-welding ezinye i-alloys, ukulandela ezi ngcebiso zeengcali kuya kwandisa kakhulu amathuba akho okufumana amalungu aqinileyo, ahlala ixesha elide.
Nokuba ungumjikijeli onamava okanye usaqala uhambo lwakho nge-alloys ephezulu ye-aluminium, ukusebenzisa iindlela ezifanelekileyo kwenza wonke umahluko.
Ngaba ukulungele ukuphakamisa iiProjekthi zakho zokuSebenza ngesinyithi?
