Analysis of Welding Electrodes in Medium-Frequency Inverter Spot Welding

Li-electrode tsa welding ke likarolo tsa bohlokoa ts'ebetsong ea ho cheselletsa sebaka sa maqhubu a mahareng. Ba ikopanya ka ho toba le li-workpieces mme ba bebofatsa ho phalla ha tjheseletsa hona joale, ho phetha karolo ea bohlokoa ho thehoeng ha li-welds tse matla le tse ka tšeptjoang. Sehloohong sena, re tla hlahloba litšobotsi le maikutlo a li-electrode tsa welding ho li-welding tse mahareng tsa maqhubu a maqhubu.

1. Lisebelisoa tsa Electrode: Khetho ea thepa ea elektrode e bohlokoa kaha e ama ka kotloloho ts'ebetso ea welding le ho tšoarella. Koporo e atisa ho sebelisoa bakeng sa li-electrode tsa ho tjheseletsa ka lebaka la conductivity ea eona e ntle ea motlakase le mocheso oa mocheso. Li-electrode tsa koporo li boetse li bonts'a ho hanyetsa mocheso le ho apara hantle, ho lumella ho sebelisoa nako e telele ntle le ho senyeha ho hoholo. Lisebelisoa tse ling tse kang li-alloys tsa koporo kapa lisebelisoa tsa refractory li ka sebelisoa bakeng sa lits'ebetso tse ikhethileng tsa welding tse hlokang thepa e ntlafalitsoeng joalo ka ho hanyetsa mocheso o phahameng kapa boima bo ntlafalitsoeng.
2. Tlhophiso ea Electrode: Li-electrode tsa welding li tla ka litlhophiso tse fapaneng ho lumellana le litlhoko tse fapaneng tsa ho cheselletsa. Litlhophiso tse atileng haholo tsa li-electrode li kenyelletsa malebela a nchocho, a bataletseng le a domed. Khetho ea tlhophiso ea li-electrode e ipapisitse le lintlha tse joalo ka mofuta oa li-workpieces, hona joale oa welding, le ho kenella ha weld ho lakatsehang. Li-electrode tse nchocho li loketse ho kenella ka hare ho weld, ha li-electrode tse bataletseng kapa tse nang le domed li atisa ho sebelisoa bakeng sa tjheseletsa e akaretsang.
3. Electrode Geometry: Geometry ea electrode e ka ama boleng ba weld le ponahalo. Sefahleho sa electrode, se tsejoang hape e le sefahleho sa ho kopana, se lokela ho bōptjoa hantle le ho hlokomeloa ho netefatsa hore ho kopana ho tsitsitseng le lisebelisoa tsa mosebetsi. Lifahleho tse boreleli le tse hloekileng tsa li-electrode li khothalletsa ho sebetsa hantle ha motlakase le mocheso, e leng se fellang ka ho fetisa mocheso o nepahetseng nakong ea ho cheselletsa. Ho hlahlojoa le ho hlokomeloa kamehla ha geometry ea electrode, ho kenyelletsa le ho tlosa litšila leha e le life kapa ho senyeha, ho bohlokoa ho boloka ts'ebetso e phahameng ea welding.
4. Bophelo le Tlhokomelo ea Electrode: Nako ea bophelo ea li-electrode tsa welding e ipapisitse le lintlha tse fapaneng, ho kenyelletsa le hona joale, nako ea welding, lisebelisoa tsa elektrode, le mofuta oa li-workpieces tse cheselitsoeng. Ha nako e ntse e ea, li-electrode li ka 'na tsa senyeha, li fetoha, kapa li silafala, tse lebisang ho fokotseha ha ts'ebetso ea li-welding. Ho hlahloba khafetsa, ho hloekisa le ho lokisa li-electrode ho ka thusa ho lelefatsa bophelo ba tsona le ho netefatsa boleng bo tsitsitseng ba weld. Electrode sharpening, polishing, kapa replacement e kanna ea hlokahala ho boloka ts'ebetso e nepahetseng ea welding.

Li-electrode tsa welding li bapala karolo ea bohlokoa katlehong ea li-welding tse mahareng tsa maqhubu a mahareng. Khetho ea lisebelisoa tse nepahetseng tsa li-electrode, tlhophiso, le mekhoa ea tlhokomelo e ama haholo ts'ebetso ea welding le boleng ba weld ka kakaretso. Ka ho utloisisa litšoaneleho le mehopolo ea li-electrode tsa welding, basebelisi ba ka etsa liqeto tse nang le tsebo, ba ntlafatsa lits'ebetso tsa bona tsa welding, 'me ba fumana li-welds tse tšepahalang le tsa boleng bo holimo.
