Flash butt welding ke mokhoa o khethehileng oa ho tjheseletsa o sebelisoang haholo liindastering tse fapaneng bakeng sa ho kopanya litšepe.Mokhoa ona o fana ka melemo e mengata, ho kenyelletsa ho nepahala ho phahameng le bokhoni ba ho tjheseletsa likarolo tse kholo tsa tšepe hammoho.Sehloohong sena, re tla hlahlobisisa melao-motheo ea ho cheselletsa flash butt le hore na e sebetsa joang.
1. Ho Utloisisa Flash Butt Welding:
Flash butt welding, eo hangata ho thoeng ke flash welding, ke ts'ebetso e tiileng ea boemo bo tiileng.E atisa ho sebelisoa ho kopanya li-workpieces tse peli tsa tšepe tse nang le sebaka se tšoanang sa cross-sectional.Mokhoa ona o loketse ka ho khetheha bakeng sa lits'ebetso tsa welding tse hlokang tekanyo e phahameng ea ho nepahala le motsoako o matla, o ts'oanang.
2. Mokhoa:
Ts'ebetso ea welding ea flash butt e kenyelletsa mehato e 'maloa ea bohlokoa:
a. Clamping:Li-workpiece tse peli tse lokelang ho chesetsoa li kentsoe mochining oa welding.The clamping force ke ea bohlokoa ho etsa bonnete ba hore ho na le weld e matla.
b. Ho tsamaisana:Ho lokisoa hantle hoa hlokahala ho fumana weld ea boleng bo holimo.Lipheletso tsa li-workpieces li hloka ho ts'oaroa hantle.
c. Resistance Heating:Motlakase oa motlakase o fetisoa ka lisebelisoa tsa mosebetsi.Hona joale sena se etsa hore mocheso o kopane pakeng tsa likotoana tse peli, e leng se etsang hore li qhibilihe ebe li etsa letamo le qhibilihisitsoeng.
d. Sebopeho sa Flash:Ha mocheso o ntse o eketseha, thepa e sehokelong e qala ho qhibiliha ebe e etsa khanya e khanyang.Flash ena ke sesupo sa hore lisebelisoa li fihla moo li qhibilihang.
e. Ho qhekella:Ka mor'a hore khanya e thehoe, mochine o sebelisa matla a ho qhekella, o sutumelletsa lisebelisoa tse peli tsa mosebetsi hammoho.Sena se etsa hore thepa e qhibilihisitsoeng e tsoe, e siea lenonyeletso le tiileng, le tšoanang.
3. Melemo ea Flash Butt Welding:
a. Nepahalo:Flash butt welding e fana ka ts'ebetso e nepahetseng le taolo holim'a ts'ebetso ea welding.E loketse lits'ebetso moo boholo bo leng bohlokoa haholo.
b. Matla:The weld e hlahisoang hangata e matla haholo 'me hangata e matla joalo ka kapa e matla ho feta thepa ea motheo.
c. Mefuta-futa:Mokhoa ona o ka sebelisoa ho cheselletsa mefuta e mengata ea litšepe le lialloys.
d. Katleho:Flash butt welding ke ts'ebetso e sebetsang, hangata e hlahisang litšila tse nyane mme e hloka lisebelisoa tse nyane kapa tse se nang letho.
e. Bohloeki:Kaha ha ho na thepa ea flux kapa filler e sebelisoang, weld e hloekile ka mokhoa o ikhethang.
4. Likopo:
Flash butt welding e fumana lits'ebetso liindastering tse fapaneng, ho kenyeletsoa likoloi, sefofane le kaho.E sebelisoa bakeng sa likarolo tsa welding joalo ka li-drive shafts, rails le likarolo tse ling tsa bohlokoa tsa sebopeho.
Flash butt welding ke mokhoa o feto-fetohang le o sebetsang oa ho kopanya lisebelisoa tsa tšepe.Ka ho sebelisa khanyetso ea motlakase le taolo e nepahetseng, e hlahisa litšepe tse matla, tse hloekileng le tse nepahetseng.Ts'ebeliso ea eona e akaretsa liindasteri tse fapaneng, e etsa hore e be mokhoa oa bohlokoa lefats'eng la ho sebetsa ka tšepe.
