Ha ho cheselletsa li-alloys tsa aluminium, likhetho tsa pele hangata li kenyelletsa tokiso ea bobeli ea mekhahlelo e merarometjhini e tjheseletsang lethebale metjhini e tjheseletsang sebaka sa polokelo ya matla. Mechini ena e khethoa hobane li-alloys tsa aluminium li na le conductivity e phahameng ea motlakase le conductivity ea mocheso.
Mechini e tloaelehileng ea li-welding tsa AC hangata ha e sebetse ho futhumatsa sebaka sa welding hore se qhibilihe kapa se be boemong ba polasetiki ho etsa lesela la weld. Ho feta moo, libaka tsa aluminium li na le tšekamelo ea ho etsa filimi ea oxide. Sebaka se qhibilihang sa aluminium oxide se phahame haholo (hoo e ka bang likhato tse 2000) ha se bapisoa le sebaka se qhibilihang sa aluminium sa likhato tse 660. Ka hona, ka nepo ho pshatla lera la oxide le ho futhumatsa nugget ea weld ho ba bohlokoa ha ho khethoa mochini oa aluminium alloy spot welding.
Ho ea ka Joule's Law Q=I²Rt, ka lebaka la motlakase o phahameng haholo le sebopeho se batlang se le bonolo sa li-alloys tsa aluminium, mechini ea ho tjheseletsa sebakeng e hloka ho ba le tlhahiso e kholo ea hajoale, e sebetsa hantle haholo, le khatello e tlase haholo. Ho fapana le litlhaloso tse tloaelehileng tse bonolo, aluminium alloy spot welding ha e khone ho sebelisa nako e telele ea ho tjheseletsa empa e hloka nako e khuts'oane ka nako e phahameng ea hona joale.
Ka ho hlahisoa ha mechini ea welding ea maqhubu a mahareng a DC, litšoaneleho tsa bona tsa tokiso e felletseng le tlhahiso e tobileng ea hona joale li ntlafalitse haholo ts'ebetso ea mocheso le phello ea ho kenella nakong ea welding. Sena se fapane le mefokolo ea ho lokisoa ha semi-wave ho mechini ea ho lokisa ea mekhahlelo e meraro le nako ea ho tsoa ha mechini ea polokelo ea matla. Ho tloha ha ho hlaha mechini ea welding ea DC spot welding, ka potlako e fetohile khetho e ratoang bakeng sa li-alloys tsa aluminium.
E-re ke u joetse, ka lebaka la phepelo ea eona e leka-lekaneng ea mekhahlelo e meraro, tlhahiso ea hona joale e tobileng, le nako ea tjheseletsa e laoloang, mochini oa welding oa DC spot welding ke khetho e ratoang bakeng sa lialloi tsa aluminium.
