Flash Butt Welding ke mokhoa oa ho tjheselletsa lintho tse ngata le o sebelisoang haholo o lumellang ho theha manonyeletso a matla ka thepa e fapaneng. Ho sa tsotellehe hore na u sebetsa ka litšepe, li-alloys, kapa esita le lisebelisoa tseo e seng tsa tšepe, ho utloisisa melao-motheo ea flash butt welding ho ka u thusa ho fumana likhokahano tse matla, tse tšepahalang. Sehloohong sena, re tla hlahloba lintlha tsa motheo tsa ts'ebetso ena le ho fana ka malebela a ho etsa bonnete ba hore manonyeletso a tiileng a sebelisa mechine ea ho tjheseletsa flash butt.
Ho utloisisa Flash Butt Welding:
Flash butt welding, eo hape e tsejoang e le resistance butt welding, e kenyelletsa ho kopanya lisebelisoa tse peli ka ho hlahisa mocheso ka ho hanyetsa motlakase. Ts'ebetso e na le mehato e 'maloa ea bohlokoa:
1. Boitokisetso:Ho qala, likarolo tse peli tsa mosebetsi li tsamaisana ka tsela e tšoanang. Ho bohlokoa ho netefatsa hore lipheletsong li hloekile ebile ha li na litšila kapa li-oxide, kaha li ka ama boleng ba weld hampe.
2. Sebopeho sa Flash:Motlakase oa motlakase o sebelisoa ho li-workpieces, ho theha mohloli oa mocheso o sebakeng sa heno ho sebopeho se kopanetsoeng. Ha mocheso o ntse o eketseha, lipheletsong tsa li-workpieces lia qhibiliha ebe li etsa letamo le qhibilihisitsoeng kapa flash.
3. Ho qapa:Khatello e sebelisoa ho li-workpieces, ho li qobella hammoho. Lintho tse entsoeng ka ho qhibilihisoa lia ntšoa, 'me lipheletso tse tiileng tse setseng lia kopana.
4. Ho ferekana:Li-workpieces li ferekane, ho bolelang hore li hatelloa ho ea pele ho ntlafatsa weld le ho felisa likheo kapa litlolo leha e le life.
5. Ho pholisa:Hang ha ho tsieleha ho phethiloe, lenonyeletso le lumelloa ho pholile, ho theha kamano e tiileng, e tsoelang pele pakeng tsa lisebelisoa tse peli tsa mosebetsi.
Litlhahiso tsa ho fumana manonyeletso a matla:
- Boloka Lisebelisoa tse Hloekileng:Joalokaha ho boletsoe pejana, bohloeki ba lisebelisoa ke tsa bohlokoa. Litšila leha e le life kapa li-oxide tse holim'a metsi li ka lebisa ho manonyeletso a fokolang. Netefatsa hore lipheletsong ha li na litšila, mafome kapa pente pele ho tjheseletsa.
- Sebopeho sa Flash e Laolehileng:Palo ea khanya e entsoeng nakong ea ts'ebetso ea welding e ka ama boleng ba lenonyeletso. Taolo e nepahetseng holim'a sebopeho sa flash ke ea bohlokoa. Flash e ngata haholo e ka lebisa tahlehelong e feteletseng ea thepa, ha e nyane haholo e ka fella ka ho se kopane ho sa phetheheng. Fetola li-parameter tsa welding, joalo ka tsa hajoale le tsa nako, ho fihlela boholo bo lakatsehang ba flash.
- Khatello e Ntle le ho Phethahatsa:Khatello e sebelisoang nakong ea mekhahlelo ea ho theha le ho ferekana e phetha karolo ea bohlokoa botšepehing ba lenonyeletso. Ho bohlokoa ho sebelisa matla a lekaneng ho etsa bonnete ba hore lisebelisoa li kopantsoe hantle ntle le ho baka mathata.
- Tekanyo ea Mochini oa Welding:Kamehla lekanya mochini oa hau oa tjheseletsa oa flash butt ho boloka taolo e nepahetseng holim'a liparamente tsa welding. Sena se tla thusa ho fumana li-welds tse tsitsitseng le tse matla.
- Tlhahlobo ea Kamor'a Weld:Ka mor'a ho cheselletsa, hlahloba lenonyeletso bakeng sa mefokolo leha e le efe kapa mekhoa e sa tšoaneng. X-ray kapa tlhahlobo ea ultrasonic e ka sebelisoa ho netefatsa boleng ba weld.
Qetellong, ho finyella manonyeletso a matla a nang le mechine ea ho tjheseletsa flash butt ho kenyelletsa motsoako oa ho itokisa hantle, ho laola mokhoa oa ho cheselletsa, le ho hlahloba ka mor'a ho cheselletsa. Ka ho latela litataiso tsena, o ka theha likhokahano tse tšepahalang le tse tšoarellang bakeng sa lits'ebetso tse fapaneng. Flash butt welding ke mokhoa oa bohlokoa lefats'eng la ho etsa lintho, 'me ho e tseba ho ka lebisa liphellong tsa boleng bo phahameng mererong ea hau.
