Mekhoa e Molemohali ea ho Welding Tungsten Carbide Tips on Saw Blades

    Malebela a welding tungsten carbide (WC) holim'a li-blades tsa sakha ke ts'ebetso ea bohlokoa e ntlafatsang ts'ebetso le nako e telele ea lisebelisoa tsa ho itšeha. Tungsten carbide e tsebahala ka ho thatafala ha eona le ho se mamelle, e e etsa sesebelisoa se loketseng bakeng sa lits'ebetso tse hlokang ho nepahala le ho tšoarella. Leha ho le joalo, ts'ebetso ea welding e tlameha ho etsoa ka hloko ho netefatsa tlamo e matla le ts'ebetso e nepahetseng. Sengoliloeng sena se fana ka lintlha tsa mekhoa e metle ea ho tjheseletsa li-tungsten carbide holim'a li-blades tsa sakha, ho shebana le boqhetseke, boitokiso le netefatso ea boleng.

1. Ho Khetha Mokhoa o Nepahetseng oa Welding

    Khetho ea mokhoa oa ho tjheseletsa e ama haholo boleng ba maqhama pakeng tsa malebela a tungsten carbide le substrate ea lehare la sakha. Mekhoa e tloaelehileng e kenyelletsa:

▷TIG Welding:Mokhoa ona o fana ka taolo e nepahetseng holim'a ho kenya mocheso, ho etsa hore e tšoanelehe bakeng sa welding tungsten carbide. Tšebeliso ea thebe ea khase e sa sebetseng e thibela tšilafalo, e netefatsa hore ho na le weld e hloekileng. TIG welding e sebetsa haholo bakeng sa malebela a masesaane a carbide, moo taolo ea mocheso e leng bohlokoa.

▷MIG Welding:Le ha ka kakaretso e potlakile ho feta TIG, welding ea MIG e ka kenya mocheso o mongata ka har'a sesebelisoa, e leng se ka bang kotsi ho bots'epehi ba carbide. E sebetsa haholo bakeng sa thepa e teteaneng le litekanyetso tse phahameng tsa tlhahiso.

▷Laser Welding:Mokhoa ona o tsoetseng pele o fokotsa sebaka se amehileng ke mocheso (HAZ) mme o lumella ho laola ka nepo, ho fokotsa kotsi ea tšenyo ea mocheso ho carbide. Laser welding e loketse lits'ebetso tse hlokang ho khopama ho fokolang.

▷ Brazing:Leha e se ts'ebetso ea welding ka se seng, brazing e ka sebelisoa ho kopanya tungsten carbide le li-substrates tsa tšepe. Mokhoa ona o sebelisa tšepe ea ho tlatsa e qhibilihang ka mocheso o tlase, kahoo e boloka thepa ea carbide.

2. Ho Lokisa Lisebelisoa

    Ho lokisa ka mokhoa o atlehileng holim'a metsi ke habohlokoa bakeng sa ho fumana cheseletso e matla. Bokaholimo ba malebela a tungsten carbide le lehare la tšepe li tlameha ho hloekisoa hantle ho tlosa litšila tse kang oli, grease kapa oxidation. Mekhoa e khothalletsoang ea ho hloekisa e kenyelletsa:

▷Abrasive Blasting:Mokhoa ona o lokisa holim'a metsi ka ho etsa sebopeho se thata, se matlafatsang maqhama a mechine.

▷ Ho hloekisa lik'hemik'hale:Ho sebelisa lihlapolli kapa lihloekisi tsa lik'hemik'hale ho ka tlosa litšila ka katleho ntle le ho fetola sebopeho sa bokaholimo.

3. Ho laola ho Kena ha Mocheso

    Ho laola ho kenya mocheso ke e 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa tsa malebela a li-welding tungsten carbide. Mocheso o feteletseng o ka lebisa ho coarsening ea carbide, e senyang ho thatafala le ho hanyetsa ho apara. Mekhoa e metle e kenyelletsa:

▷ Sebelisa Welding e Pulsed:Mokhoa ona o fokotsa mocheso o tloaelehileng ha o ntse o lumella ho kenella ka ho lekaneng.

▷ Ho hlokomela Paramethara ea Welding:Litokiso tse hlokolosi tsa motlakase, amperage le lebelo la leeto li ka thusa ho boloka mocheso o nepahetseng.

▷Ho futhumatsa Substrate:Maemong a mang, ho futhumatsa lehare la tšepe pele ho ka thusa ho fokotsa ho tšoha ha mocheso le ho fokotsa monyetla oa ho phatloha.

4. Ka mor'a ho Welding Phekolo

Phekolo ea mocheso ka mor'a weld e bohlokoa bakeng sa ho imolla khatello ea maikutlo e setseng le ho ntlafatsa thepa ea mochini oa weld. Mekhoa e tloaelehileng e kenyelletsa:

▷ Ho futhumatsa:Ts'ebetso ena e kenyelletsa ho futhumatsa lenonyeletso le cheselitsoeng mochesong o itseng o lateloang ke pholiso e laoloang, e ka ntlafatsang ho tiea le ho fokotsa ho hlaka.

▷ Ho Fokotsa Khatello ea Maikutlo:Ho etsa phekolo ea mocheso e fokotsang khatello ea maikutlo ho ka thusa ho fokotsa khatello leha e le efe e hlahisoang nakong ea welding, ho netefatsa botšepehi ba bond.

5. Mehato ea ho laola boleng

    Ho kenya ts'ebetsong taolo e matla ea boleng ho bohlokoa ho netefatsa ho ts'epahala le ts'ebetso ea malebela a welded tungsten carbide. Mekhoa e khothalelitsoeng e kenyelletsa:

▷Teko e sa Senyeheng (NDT):Mekhoa e joalo ka tlhahlobo ea ultrasonic, tlhahlobo ea radiographic, kapa tlhahlobo ea dae e kenang ka har'a dae e ka tseba mefokolo ho weld ntle le ho senya karolo.

▷ Tlhahlobo ea Pono:Ho etsa tlhahlobo e phethahetseng ea pono ea sebaka sa weld ho ka thusa ho lemoha ho se lekane ha holim'a metsi kapa matšoao a ho se kopane hantle.

▷Ho Ikamahanya le Maemo:Ho latela litekanyetso le litlhaloso tsa indasteri, tse kang tse thehiloeng ke American Welding Society (AWS), li tiisa boleng bo tsitsitseng le ts'ebetso.

Qetello

Ho tjheseletsa malebela a tungsten carbide ka katleho mahareng a sakha ho hloka tlhokomelo e hlokolosi ho boqhetseke, boitokiso le taolo ea boleng. Ka ho khetha mokhoa o nepahetseng oa ho tjheseletsa, ho laola ho kenya mocheso, le ho kenya ts'ebetsong mekhoa ea ho hlahloba ka botlalo, bahlahisi ba ka hlahisa lisebelisoa tsa boleng bo phahameng ba ho itšeha tse finyellang litlhoko tsa mefuta e sa tšoaneng. Ha theknoloji e ntse e hatela pele, ntlafatso e tsoelang pele ea mekhoa ea ho tjheseletsa e tla ntlafatsa ts'ebetso le ho tšoarella ha lisebelisoa tsa ho seha li-tungsten carbide, ho tiisa karolo ea bona tlhahisong ea sejoale-joale le machining.
