Litlhoko tsa boleng bakeng sa ho Welding ea Mid-Frequency Direct Current Spot Welding

Lits'ebetsong tsa morao-rao tsa tlhahiso, ho cheselletsa matheba ho bapala karolo ea bohlokoa ho kopanya likarolo tsa tšepe. Mechini ea ho tjheseletsa sebakeng sa Mid-frequency direct current (MFDC) e se e tumme haholo ka lebaka la bokhoni ba eona ba ho hlahisa litšepe tsa boleng bo holimo ka nepo le ka bokhabane. Sehloohong sena, re tla shebana le litlhoko tsa bohlokoa tsa boleng bakeng sa lintlha tsa weld tse hlahisoang ke mechini ea welding ea MFDC.

1. Ho lumellana ha Lintho: Ntho ea pele le e ka sehloohong eo ho nahanoang ka eona ho finyella li-welds tsa boleng bo botle ke ho netefatsa hore lisebelisoa tse kopantsoeng li lumellana. MFDC spot welding e loketse mefuta e mengata ea litšepe, ho kenyeletsoa tšepe, tšepe e sa hloekang, aluminium le koporo. Ho bohlokoa ho khetha liparamente tse nepahetseng tsa welding le lisebelisoa tsa elektrode bakeng sa motsoako o mong le o mong oa thepa ho fihlela weld e matla le e tšoarellang.
2. Weld Matla: Sepheo sa mantlha sa weld leha e le efe ke ho theha maqhama a matla pakeng tsa likotoana tse peli tsa tšepe. Quality MFDC spot welding e lokela ho fella ka li-welds tse nang le matla a holimo le a ho kuta, ho netefatsa hore lenonyeletso le khona ho mamella khatello le meroalo e reriloeng.
3. Ho lumellana: Ho tsitsisa ke senotlolo sa ho fihlela li-welds tsa boleng bo holimo. Mechini ea ho tjheseletsa matheba ea MFDC e lokela ho hlongoa le ho hlokomeloa ho fana ka litšepe tse tsitsitseng nakong eohle ea tlhahiso. Sena se kenyelletsa ho boloka tekano e nepahetseng ea li-electrode, khatello, le phallo ea hona joale.
4. Sebaka se Ametsoeng ke Mocheso o Monyane (HAZ): Mocheso o feteletseng o ka lebisa sebakeng se pharaletseng se amehileng ke mocheso (HAZ) ho potoloha weld, e ka 'nang ea fokolisa thepa. Ho tjheseletsa sebakeng sa boleng ba MFDC ho fokotsa HAZ, ho netefatsa hore thepa e potileng e boloka thepa ea eona ea mantlha ka hohle kamoo ho ka khonehang.
5. Ha ho Porosity kapa Inclusions: Porosity le inclusions ka hare ho weld li ka senya botšepehi ba eona. Quality MFDC spot welding e hlahisa li-welds tse nang le bonyane ho isa ho tse se nang porosity kapa li-inclusions, tse netefatsang motsoako o se nang sekoli.
6. Setlolo Ponahalo: Le hoja botšepehi ba sebopeho sa weld bo le bohlokoa, ponahalo ea litlolo e boetse e bohlokoa, haholo-holo lits'ebetsong moo li-welds li bonahalang. Ho cheselletsa matheba a boleng ba MFDC ho lokela ho fella ka litšepe tse hloekileng le tse khahlisang ka bokhabane.
7. Tlhokomelo ea Ts'ebetso: Ho kenya ts'ebetsong mehato ea ho hlahloba le ho laola boleng ho bohlokoa. Sena se kenyelletsa tlhahlobo ea khafetsa, liteko tse sa senyeheng, 'me, ha ho hlokahala, liteko tse senyang ho netefatsa boleng ba weld.
8. Mekhahlelo ea Welding: Ho beha liparamente tsa welding ka nepo joalo ka ha joale, nako le khatello ho bohlokoa. Mekhahlelo ena e tlameha ho fetoloa ho latela botenya ba thepa, mofuta le litlhoko tse ikhethileng tsa welding.
9. Mehato ea Tšireletseho: Tšireletseho ke ntho e tlang pele mosebetsing ofe kapa ofe oa ho cheselletsa. Basebelisi ba lokela ho koetlisetsoa mekhoa e sireletsehileng ea ho cheselletsa, 'me lisebelisoa tsa ho cheselletsa li lokela ho finyella litekanyetso tsohle tsa polokeho ho thibela likotsi le ho sireletsa basebetsi.

Qetellong, ho fihlela lintlha tsa boleng bo holimo ka mochini oa welding oa MFDC ho hloka tlhokomelo e hlokolosi ea ho lumellana ha lintho tse bonahalang, ho tsitsana, matla, le ho fokotsa liphoso. Ho kenya ts'ebetsong mekhoa e nepahetseng ea li-welding, mekhoa ea ho beha leihlo, le ho netefatsa hore mehato ea tšireletso e teng ke mehato ea bohlokoa ho finyella litlhoko tsena tsa boleng. Ha e etsoa ka mafolo-folo, MFDC spot welding e ka fana ka li-welds tse nepahetseng, tse matla le tse ka tšeptjoang, e leng se etsang hore e be mokhoa oa bohlokoa liindastering tse fapaneng tsa tlhahiso.
