Ngowuphi umatshini wokuwelda osetyenziselwa ukuwelda iialloyi zealuminium?

Xa udibanisa i-alloys ye-aluminium, ukhetho lwangaphambili luhlala lubandakanya ukulungiswa kwesigaba sesithathuoomatshini bokuwelda amabalakunye noomatshini bokuwelda indawo yokugcina amandla. Aba matshini bakhethwa ngenxa yokuba i-aluminium alloys ine-conductivity ephezulu yombane kunye ne-thermal conductivity.

Oomatshini bokuwelda bamabala be-AC abaqhelekileyo abasebenzi ngokubanzi ekufudumezeni indawo ye-welding ekunyibilikeni okanye kwimo yeplastiki ukwenza i-weld nugget. Ngaphezu koko, imiphezulu ye-aluminiyam ithande ukwenza ifilimu ye-oxide. Indawo yokunyibilika ye-aluminiyam oxide iphezulu kakhulu (phantse i-2000 degrees) xa kuthelekiswa nendawo yokunyibilika kwe-aluminiyam ye-660 degrees. Ke ngoko, ukophula ngokufanelekileyo umaleko we-oxide kunye nokufudumeza i-weld nugget iba yinto ebalulekileyo ekukhetheni umatshini wokuwelda indawo ye-aluminium.

NgokoMthetho kaJoule Q=I²Rt, ngenxa yombane ophezulu kunye nokuthamba okuthambileyo kwealluminiyam, oomatshini bokuwelda kufuneka babenemveliso yangoku enkulu, ukusebenza kakuhle kwe-thermal, kunye noxinzelelo oluphantsi. Ngokungafaniyo neenkcukacha ezithambileyo eziqhelekileyo, i-aluminiyam i-alloy spot welding ayikwazi ukusebenzisa amaxesha amade we-welding kodwa ifuna ubude obufutshane ngokuphezulu kwangoku.

Ngokungeniswa kwe-medium frequency inverter ye-DC spot welding machines, iimpawu zabo zokulungiswa kwamaza ngokupheleleyo kunye nesiphumo esithe ngqo sangoku siphucule kakhulu ukusebenza kakuhle kwe-thermal kunye nesiphumo sokungena ngexesha le-welding. Oku kuchasene neentsilelo zokulungiswa kwe-semi-wave kumatshini wokulungiswa kwesigaba sesibini kunye nexesha lokukhutshwa koomatshini bokugcina amandla. Ukusukela ekuveleni okuphakathi frequency inverter DC indawo koomatshini welding, baye bakhawuleza baba lolona khetho lukhethwayo lwe-welding aluminiyam ialloys.

Makhe ndikuxelele, ngenxa yonikezelo lwamandla olulinganayo lwesigaba esithathu, imveliso yangoku ngokuthe ngqo, kunye nexesha lokuwelda elilawulekayo, umatshini wokuwelda we-DC ophakathi ngamaza ombane lukhetho olukhethiweyo lokuwelda ialloyi zealuminium.
