Li-alloys tsa Aluminium tse nang le Medium Frequency Inverter Spot Welding?

Li-alloys tsa aluminium tse chesehang li hlahisa mathata a ikhethang ka lebaka la thepa le litšobotsi tsa tsona tse ikhethang. Medium frequency inverter spot welding ke mokhoa o sebetsang oa ho kopanya li-alloys tsa aluminium, tse fanang ka li-welds tse tšepahalang le tsa boleng bo holimo. Sehloohong sena, re tla hlahloba lintlha tsa bohlokoa le mekhoa ea ho tjheseletsa li-alloys tsa aluminium ho sebelisa mochini oa welding oa maqhubu a mahareng.

Khetho ea Aluminium Alloy:
Li-alloys tsa aluminium li tla ka limaraka tse fapaneng tse nang le libopeho le thepa e fapaneng. Ho bohlokoa ho khetha motsoako o nepahetseng oa aluminium bakeng sa ts'ebeliso e khethehileng le litlhoko tsa welding. Lintlha tse kang matla, ho hanyetsa kutu, le ho cheseha li lokela ho nkoa ha u khetha motsoako.
Tokiso e Nepahetseng ea Sebaka:
Libaka tsa aluminium li tlameha ho hloekisoa ka hloko le ho lokisoa pele ho tjheseletsa. Aluminium oxide, e hlahang ka potlako holim'a metsi, e ka thibela sebopeho se nepahetseng sa weld. Mekhoa ea mechine e kang ho hlatsoa ka terata kapa ho hloekisa ka mokhoa o senyang, hammoho le ho hloekisa lik'hemik'hale ho sebelisa metsoako kapa metsoako ea alkaline, hangata e sebelisoa ho tlosa likarolo tsa oxide le ho etsa bonnete ba hore libaka tse hloekileng.
Tšebeliso ea Sepakapaka sa Tšireletso:
Aluminium e sebetsa haholo ho oksijene le mongobo moeeng, e lebisang ho thehoeng ha oxide nakong ea ho cheselletsa. Ho thibela oxidation le ho boloka boleng ba weld, ho bohlokoa ho theha tikoloho e sireletsang ho potoloha sebaka sa weld. Sena se ka finyelloa ka ho sebelisa likhase tse sireletsang, tse kang argon kapa helium, nakong ea ts'ebetso ea welding.
Mekhatlo e nepahetseng ea Welding:
Mekhahlelo ea ho tjheseletsa, ho kenyeletsoa hona joale, nako le matla a eleketrode, e lokela ho lokisoa ka hloko bakeng sa li-alloys tsa aluminium. Aluminium e na le conductivity e phahameng ea mocheso ha e bapisoa le litšepe tse ling, e hlokang maqhubu a phahameng a ho cheselletsa ho finyella mocheso o nepahetseng le motsoako. Ho feta moo, ho ka 'na ha hlokahala nako e telele ea ho cheselletsa ho lefella litšobotsi tsa aluminium tse felisang mocheso.
Khetho ea Electrode:
Ho khetha thepa e nepahetseng ea li-electrode ho bohlokoa bakeng sa welding e atlehileng ea aluminium. Lisebelisoa tsa koporo li atisa ho sebelisoa e le li-electrode ka lebaka la conductivity ea tsona e ntle ea mocheso le ho lumellana le aluminium. Sebopeho le boholo ba elektrode le tsona li lokela ho nahanoa ho netefatsa kabo e nepahetseng ea mocheso le bophelo ba li-electrode.
Moralo o Kopanetsoeng le ho Lokisa:
Moralo o nepahetseng oa kopanelo ke oa bohlokoa bakeng sa ho cheselletsa li-alloys tsa aluminium. Manonyeletso a Butt, lap joints, le T-joints ke tlhophiso e tloaelehileng e sebelisoang ho cheselletsa aluminium. Ho kopanya ka kopanelo, ho kenyeletsoa sebaka sa lekhalo le ho lokisoa ha moeli, ho lokela ho laoloa ka hloko ho netefatsa ho kenella le ho kopanya ho lekaneng nakong ea ts'ebetso ea welding.
Li-alloys tsa aluminium tse nang le mochini oa welding oa frequency inverter spot welding li hloka lintlha tse ikhethang ho fihlela li-welds tsa boleng bo holimo. Ka ho khetha motsoako o loketseng oa aluminium, ho lokisa bokaholimo, ho sebelisa sepakapaka se sireletsang, ho ntlafatsa maemo a ho tjheseletsa, le ho sebelisa li-electrode tse loketseng, li-welders li ka etsa bonnete ba hore li-welds tsa aluminium tse atlehileng le tse tšepahalang. Moralo o nepahetseng oa kopanelo le ho kopanya hantle le tsona li kenya letsoho ho boleng ba weld ka kakaretso. Ka mekhoa le menahano ena, ho tjheseletsa ha leqhubu la maqhubu a mahareng ho ipakile e le mokhoa oa bohlokoa oa ho kopanya lisebelisoa tsa aluminium liindasteri tse fapaneng, ho kenyeletsoa lisebelisoa tsa likoloi, tsa sefofane le tsa metsing.
