I-Welding aluminium alloys inikezela imingeni ekhethekileyo ngenxa yeempawu zabo ezithile kunye neempawu.I-Medium frequency inverter spot welding yindlela esebenzayo yokujoyina i-alloys ye-aluminium, ukubonelela ngokuthembekileyo kunye nomgangatho ophezulu we-welds.Kweli nqaku, siza kuphonononga eyona ngqwalasela kunye nobuchule bokuwelda ialluminiyamu ialloys kusetyenziswa umatshini wokuwelda indawo yokutshintsha okuphakathi.
Ukukhethwa kweAluminiyam yeAluminiyam:
I-alloys ye-aluminiyam iza kumabanga ahlukeneyo kunye nezakhiwo ezahlukeneyo kunye neempawu.Kubalulekile ukukhetha i-alloy ye-aluminium efanelekileyo kwisicelo esithile kunye neemfuno ze-welding.Izinto ezifana namandla, ukuxhathisa ukubola, kunye ne-weldability kufuneka ziqwalaselwe xa ukhetha i-alloy.
ULungiselelo olululo lomphezulu:
Imiphezulu yealuminiyam kufuneka icocwe ngobuchule kwaye ilungiswe phambi kokuba iwelding.I-aluminium oxide, eyenza ngokukhawuleza phezu komhlaba, inokuthintela ukubunjwa okufanelekileyo kwe-weld.Iindlela zoomatshini ezifana nokuxubha ucingo okanye ukucocwa kwe-abrasive, kunye nokucocwa kweekhemikhali usebenzisa i-solvents okanye izisombululo ze-alkaline, zisetyenziswa ngokuqhelekileyo ukususa iileyile ze-oxide kunye nokuqinisekisa iindawo ezicocekileyo.
Ukusetyenziswa kwe-Atmosphere eKhuselekileyo:
I-Aluminiyam iyasebenza kakhulu kwioksijini kunye nokufuma emoyeni, okukhokelela ekwenziweni kweoksidi ngexesha le-welding.Ukuthintela i-oxidation kunye nokugcina umgangatho we-weld, kubalulekile ukudala umoya okhuselayo ojikeleze indawo ye-weld.Oku kunokufezekiswa ngokusebenzisa iigesi zokukhusela, ezifana ne-argon okanye i-helium, ngexesha lenkqubo ye-welding.
Ezona Parameters zokuWelding:
Iiparamitha ze-welding, kubandakanywa i-welding yangoku, ixesha, kunye namandla e-electrode, kufuneka ilungiswe ngononophelo kwii-alloys ze-aluminium.I-Aluminiyam ine-thermal conductivity ephezulu xa kuthelekiswa nezinye isinyithi, ifuna imisinga ye-welding ephezulu ukufezekisa ukufudumeza okufanelekileyo kunye nokudibanisa.Ukongezelela, amaxesha amade e-welding anokuba yimfuneko ukuhlawulela iimpawu zokutshatyalaliswa kobushushu be-aluminium.
Ukhetho lwe-Electrode:
Ukukhetha imathiriyeli ye-electrode efanelekileyo kubalulekile kwi-welding ye-aluminium eyimpumelelo.I-alloys zethusi zisetyenziswa ngokuqhelekileyo njenge-electrodes ngenxa ye-conductivity efanelekileyo ye-thermal kunye nokuhambelana ne-aluminium.Ubume be-electrode kunye nobukhulu kufuneka kwakhona kuqwalaselwe ukuqinisekisa ukusabalalisa ubushushu obufanelekileyo kunye nobomi be-electrode.
Uyilo oluDityanisiweyo kunye noFit-up:
Uyilo oludibeneyo olufanelekileyo luyimfuneko kwi-welding aluminium alloys.Amalungu empundu, amalunga emilenze, kunye ne-T-joints lulungelelwaniso oluqhelekileyo olusetyenziswa kwi-aluminium welding.Ukudibanisa okudibeneyo, kubandakanywa umgama we-gap kunye nokulungiswa komphetho, kufuneka kulawulwe ngokucophelela ukuze kuqinisekiswe ukungena okwaneleyo kunye nokudibanisa ngexesha lenkqubo ye-welding.
Welding aluminiyam alloys kunye medium frequency inverter spot welding umatshini kufuna ingqwalasela ethile ukuphumeza welds ezikumgangatho ophezulu.Ngokukhetha i-alloy ye-aluminium efanelekileyo, ukulungisa umgangatho, ukusebenzisa umoya okhuselayo, ukulungelelanisa imilinganiselo ye-welding, kunye nokusebenzisa i-electrode efanelekileyo, i-welders inokuqinisekisa ukuphumelela kunye nokuthembeka kwe-aluminium welds.Uyilo oludityanisiweyo olululo kunye nokulungelelanisa ngakumbi igalelo kumgangatho we-weld ngokubanzi.Ngobu buchule kunye noqwalaselo, i-medium frequency inverter spot welding ibonakalisa ukuba yeyona ndlela ixabisekileyo yokujoyina ialloys ze-aluminium kumashishini ahlukeneyo, kubandakanya izithuthi, i-aerospace, kunye nokusetyenziswa kolwandle.
