MFDC DC Inverter Spot Welder: Me yasa Yana da Muhimmanci don Welding Aluminum

Aluminum, tare da sifarsa mara nauyi da ƙaƙƙarfan ƙaƙƙarfan{0}, ya zama abu mai mahimmanci a ɓangarorin masana'antu na ci gaba kamar motocin lantarki (EVs), sararin samaniya, da na'urorin lantarki masu amfani. Koyaya, walda aluminium tsari ne mai rikitarwa, yana gabatar da ƙalubale guda biyu saboda abubuwan da ke tattare da shi:

1. High thermal Conductivity: Aluminum yana watsar da zafi sosai cikin sauri, yana sa ya zama da wahala a tattara makamashin thermal a cikin yankin weld, don haka yana buƙatar shigarwar makamashi mai girma nan take.
2. Rapid Oxidation: Fim ɗin oxide mai yawa, tare da ma'aunin narkewa na kusan digiri na 2000, yana haɓaka da sauri akan saman aluminum, yayin da alloy ɗin aluminium kanta ya narke tsakanin digiri 520 da digiri 660. Wannan Layer oxide yana da matuƙar hana ingantaccen kwarara na yanzu da samuwar walda.

Fuskantar waɗannan ƙalubalen, mitar layi na gargajiya Alternating Current (AC) tabo walda galibi basu isa ba. Matsakaici Mitar Kai tsaye na Yanzu (MFDC) Inverter Spot Welder ya fito a matsayin mafificin bayani a cikin walda na aluminium, godiya ga ingantaccen madaidaicin iko da halayen fitar da kuzari.

MFDC inverter spot welder yana aiki ta farko ta gyara daidaitaccen ƙarfin AC 50/60Hz zuwa DC, sannan a juyar da shi zuwa matsakaicin 1{3}}4kHz{4}matsakaici na halin yanzu ta amfani da fasahar inverter mai mita. Wannan ci gaban fasaha yana ba da fa'idodi masu mahimmanci:

Al'adun AC tabo walda suna fuskantar katsewar kuzari lokacin da yanayin ƙawancen na yanzu ya ketare sifili, yana haifar da shigar da zafi mara ƙarfi. Fasahar MFDC tana fitar da ingantaccen halin yanzu na DC, wanda ke tabbatar da:
