Chii chakatarisana naHard?

Kutarisa kwakaoma, kunonziwo kuomeswa kwepamusoro, isimbi yekugadzira simbi dzakasimba, alloys epamusoro-tembiricha, maceramics uye zvimwe zvakafukidzwa kusimbi dzepasi kuti awedzere kupfeka kwakajairwa, ngura, kuoma uye humwe hunhu hwemuviri nekemikari hwesimbi yepasi.

uye kumwe kuvharirwa kumasimbi epasi kuti awedzere kupfeka kwakajairwa, ngura, kuomarara uye humwe hunhu hwemuviri nekemikari hwesimbi yepasi.

Nguva yeKuoma kumeso?

Kutarisana kwakaoma nguva dzose kunoiswa mukati mehupenyu hwese hwechikamu chakagadzirwa kana chemuchina. Kazhinji, kutarisana kwakaoma kunoshandiswa.

Pamusoro pezvikamu zvitsva kuti uwedzere kupikisa kupfeka.

Pane yakashandiswa, yakasakara-pasi pasi kudzokera kushiviriro, kurebesa hupenyu hwekushanda.

Pamichina inoshanda yekuwedzera hupenyu hwezvakagadzirwa zvikamu sechikamu chekugadzirisa chirongwa.

Iyo Hard yakatarisana inoiswa sei?

Pane nzira dzakawanda dzekushandisa zvakaoma kutarisana. Idzo nzira dzinoshandiswa kune dzakasiyana siyana. Saka hapana imwe nzira iri nani kune dzimwe, asi iyo nzira inokurudzirwa yakavakirwa pachinangwa chakanangana nekuoma kwakatarisana. Dzimwe dzedzakajairika nzira dzewelding dzinosanganisira:

1. Shield Metal Arc Welding (SMAW)

2. Gasi Metal Arc Welding (GMAW)

3. Oxyfuel Welding (OFW)

4. Submerged Arc Welding (SAW)

5. Electrical Welding (ESW)

6. Plasma Yakatamiswa Arc Welding (PTAW)

7. Thermal Spraying

8. Cold polymer compounds

9. Laser Cladding

Kutarisana kwakaoma kwakaiswa muzvirongwa zvekutenga nekugadzirisa zvemaindasitiri akasiyana siyana anosanganisira, asi asina kuganhurirwa kune, Simbi, Simende, Migodhi, Petrochemical, Simba, Nzimbe uye Chikafu, Process Chemical, pamwe nevagadziri vese.

Izvo Zvishandiso uye Mari yezvakaoma zvakatarisana

Nzira yakaoma-yakatarisana yebasa inobva pane geometry yechikamu uye mari yakaenzana yenzira yakaoma-yakatarisana. Mitengo inogona kusiyana nedeposition rate yezvinhu.

Izvi zvakasiyana-siyana zvemitengo zvinogona kupfupikiswa sezvizvi:

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

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

•Gasi Metal Arc Welding (GMAW), inosanganisira ese ari maviri-akadzivirirwa uye akavhurika arc welding 5 kusvika 12 lb/hr.

•Oxyfuel Welding (OFW) 5 kusvika 10 lb/hr

Kana iwe uchida kudzidza zvakawanda pamusoro penzira dzakaoma, maapplication, kana kutsvaga kubvunzana, bata zzbetter carbide.
