I-Welding Aluminium Alloys ene-Medium Frequency Inverter Spot Welding?

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 yokuqhuba kakuhle kwe-thermal kunye nokuhambelana ne-aluminium. Ubume be-electrode kunye nobukhulu kufuneka kwakhona kuqwalaselwe ukuqinisekisa ukuhanjiswa kobushushu 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 olufanelekileyo kunye nokulungelelaniswa ngakumbi kunegalelo 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.
