Hard tobane le eng?

Sefahleho se thata, seo hape se bitsoang hard surfacing, ke ts'ebetso ea ts'ebetso ea tšepe ea ho sebelisa litšepe tse thata, li-alloys tse nang le mocheso o phahameng, lirafshoa le lintho tse ling tse koahelang litšepe tsa motheo ho matlafatsa moaparo o tloaelehileng, kutu, ho thatafala le litšobotsi tse ling tsa 'mele le tsa lik'hemik'hale tsa tšepe ea motheo.

le lintho tse ling tse koahelang litšepe tsa motheo ho ntlafatsa moaparo o tloaelehileng, kutu, ho thatafala le litšobotsi tse ling tsa 'mele le tsa lik'hemik'hale tsa tšepe ea motheo.

Neng ho Hard sefahleho?

Sefahleho se thata se lula se sebelisoa nakong eohle ea bophelo ba karolo e entsoeng kapa ea mochini. Ka kakaretso, sefahleho se thata se sebelisoa.

Likarolong tse ncha ho eketsa khanyetso ea ho roala.

Ha e sebelisoa, sebaka se senyehileng se khutlela ho mamello, lelefatsa bophelo ba ho sebetsa.

Ho lisebelisoa tse sebetsang ho lelefatsa bophelo ba likarolo tse entsoeng e le karolo ea lenaneo la tlhokomelo.

Hardface e sebelisoa joang?

Ho na le mekhoa e mengata ea ho sebelisa litlolo tse thata. Mekhoa ena e sebelisoa bakeng sa lisebelisoa tse fapaneng. Kahoo ha ho mokhoa o le mong o phahametseng ba bang, ho e-na le hoo, mokhoa ona o khothaletsoa ho latela morero o reriloeng oa ho toba ka thata. E meng ea mekhoa e tloaelehileng ea welding e kenyelletsa:

1. Shield Metal Arc Welding (SMAW)

2. Gas Metal Arc Welding (GMAW)

3. Oxyfuel Welding (OFW)

4. Submerged Arc Welding (SAW)

5. Ho Welding Motlakase (ESW)

6. Plasma Transferred Arc Welding (PTAW)

7. Thermal Spraying

8. Metsoako e batang ea polymer

9. Laser Cladding

Ho shebana ka thata ho kenyelelitsoe mananeong a ho reka le ho hlokomela liindasteri tse fapaneng ho kenyeletsoa, ​​​​empa ho sa felle feela, Litšepe, Samente, Merafo, Petrochemical, Matla, 'Moba le Lijo, Process Chemical, hammoho le baetsi ba kakaretso.

Thepa le Litšenyehelo tsa sefahleho se thata

Mokhoa o thata oa ho sebetsana le mosebetsi o itšetlehile ka geometry ea karolo le litšenyehelo tse lekanyelitsoeng tsa mokhoa o thata. Litšenyehelo li ka fapana ho latela sekhahla sa deposition ea thepa.

Phapang ena ea litšenyehelo e ka akaretsoa ka tsela e latelang:

•Flux-cored arc welding (FCAW) 8 ho isa ho 25 lb/hr

•Shielded Metal Arc Welding (SMAW) 3 ho isa ho 5 lb/hr

•Gas Metal Arc Welding (GMAW), ho kenyelletsa le litšepe tse sirelelitsoeng ka khase le tse bulehileng tsa arc 5 ho isa ho 12 lb/hr.

•Oxyfuel Welding (OFW) 5 ho isa ho 10 lb/hr

Haeba u thahasella ho ithuta haholoanyane ka mekhoa e thata, lits'ebetso, kapa ho batla therisano, ikopanye le zzbetter carbide.
