Pre-Weld Workpiece Cleaning bakeng sa Flash Butt Welding Machine

Flash butt welding ke mokhoa o sebelisoang haholo indastering ea welding bakeng sa ho kopanya lisebelisoa tsa tšepe. Ho netefatsa li-welds tse matla le tse tšepahalang, ho bohlokoa ho lokisa li-workpieces hantle ka ho li hloekisa pele ho ts'ebetso ea welding. Sehloohong sena, re tla hlahloba bohlokoa ba ho hloekisa li-workpiece pele ho weld bakeng sa mechine ea ho tjheseletsa flash butt.

Flash butt welding, eo hape e tsejoang e le resistance butt welding, e kenyelletsa ho kopanya lisebelisoa tse peli tsa tšepe ka ho hlahisa mocheso ka ho hanyetsa, ho fella ka weld ea boleng bo holimo. Katleho ea ts'ebetso ena ea welding e itšetlehile haholo ka bohloeki ba li-workpieces tse kopantsoeng. Mona ke a mang a mabaka a bohlokoa a etsang hore ho hloekisoa ha mosebetsi pele ho weld ho le bohlokoa:

1. Ho tlosoa ha Litšila: Lisebelisoa tsa mosebetsi hangata li na le litšila tse kang mafome, pente, mafura le litšila holim'a tsona. Lintho tsena tse silafatsang li ka sitisa ts'ebetso ea welding ka ho thibela ho kopana ho nepahetseng ha motlakase le ho tsamaisa mocheso. Ho hloekisa li-workpieces ho netefatsa hore litšila tsena lia tlosoa, ho lumella boleng bo botle ba weld.
2. Ts'ebetso e Ntlafetseng ea Motlakase: Lisebelisoa tse hloekileng tsa mosebetsi li na le tsamaiso e ntle ea motlakase, e leng ea bohlokoa bakeng sa ts'ebetso ea ho cheselletsa flash butt. Ha li-workpieces li kopana, hona joale ho feta ho tsona, ho hlahisa mocheso sebakeng sa ho kopana. Libaka tse hloekileng li thusa ho phalla hantle hona joale, ho fella ka ts'ebetso e sebetsang le e laoloang ea welding.
3. Litšitiso tse Fokotseng: Litšitiso tse kang li-void, cracks, le li-inclusions, li ka etsahala haholo ha lisebelisoa tsa mosebetsi li sa hloekisoa hantle. Libaka tse hloekileng li khothalletsa cheseletso e tšoanang, ho fokotsa menyetla ea liphoso tsena le ho netefatsa hore sebopeho sa weld sea tšepahala.
4. Ponahalo e ntlafetseng ea Weld: Lisebelisoa tse hloekileng tsa mosebetsi li lebisa ponahalong e hloekileng le e khahlisang haholoanyane. Sena se bohlokoa haholo lits'ebetsong tseo ho tsona ho amehang boleng ba pono ea weld, joalo ka liindasteri tsa likoloi kapa tsa sefofane.

Ts'ebetso ea ho hloekisa li-workpiece pele ho weld hangata e kenyelletsa tšebeliso ea mekhoa e fapaneng, joalo ka ho hloekisoa ka li-abrasive, ho hloekisa lik'hemik'hale, kapa ho hloekisa ka mochini, ho latela mofuta le boemo ba lisebelisoa. Khetho ea mokhoa oa ho hloekisa e lokela ho etsoa ho nahanoa ka litlhoko tse khethehileng tsa morero oa welding.

Qetellong, ho hloekisa li-workpiece tsa pele ho weld ke mohato oa bohlokoa ts'ebetsong ea ho cheselletsa flash butt. E netefatsa ho tlosoa ha litšila, e matlafatsa tsamaiso ea motlakase, e fokotsa liphoso, 'me e ntlafatsa boleng ba kakaretso ea weld. Ka ho tsetela ho hloekiseng li-workpiece tse nepahetseng, li-welders li ka fumana li-welds tse matla, tse ka tšeptjoang le tse khahlehang, tse finyellang litekanyetso tse phahameng ka ho fetisisa tsa indasteri.
