Hard ntsib yog dab tsi?

Lub ntsej muag tawv, tseem hu ua hard surfacing, yog txheej txheem hlau ua haujlwm ntawm kev siv cov hlau hnyav dua, cov hlau kub kub, ceramics thiab lwm yam overlays rau hauv cov hlau los txhim kho cov qauv hnav, corrosion, hardness thiab lwm yam khoom siv lub cev thiab tshuaj lom neeg ntawm lub hauv paus hlau.

thiab lwm yam overlays rau lub hauv paus hlau los txhim kho cov qauv hnav, corrosion, hardness thiab lwm yam ntxwv ntawm lub cev thiab tshuaj lom neeg ntawm lub hauv paus hlau.

Thaum twg Hard Face?

Lub ntsej muag tawv ib txwm yog siv rau txhua lub sijhawm ntawm lub neej ntawm cov khoom tsim los yog lub tshuab ua haujlwm. Feem ntau, lub ntsej muag tawv yog siv.

Ntawm qhov tshiab los ua kom cov hnav tsis kam.

Thaum siv, hnav-down nto rov qab rau kev kam rau siab, ncua lub neej ua haujlwm.

Ntawm cov khoom siv ua haujlwm kom ntev lub neej ntawm fabricated Cheebtsam raws li ib feem ntawm kev saib xyuas.

Yuav ua li cas yog lub Hard ntsej muag?

Muaj ntau txoj hauv kev los siv lub ntsej muag nyuaj. Cov txheej txheem no yog siv rau ntau daim ntawv thov. Yog li tsis muaj ib txoj hauv kev zoo tshaj rau lwm tus, es txoj kev pom zoo raws li lub hom phiaj ntawm lub ntsej muag nyuaj. Qee txoj hauv kev welding feem ntau suav nrog:

1. Shield Hlau Arc Vuam (SMAW)

2. Gas Metal Arc Vuam (GMAW)

3. Oxyfuel Vuam (OFW)

4. Submerged Arc Vuam (SAW)

5. Hluav taws xob vuam (ESW)

6. Plasma Transferred Arc Vuam (PTAW)

7. Thermal Txau

8. Cold polymer tebchaw

9. Laser Cladding

Lub ntsej muag tawv tau muab tso rau hauv kev yuav khoom thiab kev saib xyuas rau ntau yam kev lag luam suav nrog, tab sis tsis txwv rau, Hlau, Cement, Mining, Petrochemical, Fais Fab, Qab Zib thiab Khoom Noj, Txheej Txheem Tshuaj, nrog rau cov tuam txhab dav dav.

Cov khoom siv thiab cov nqi ntawm lub ntsej muag nyuaj

Cov txheej txheem nyuaj rau kev ua haujlwm yog nyob ntawm qhov geometry ntawm ib feem thiab tus nqi txheeb ze ntawm txoj kev nyuaj. Cov nqi tuaj yeem sib txawv nrog tus nqi tso nyiaj ntawm cov khoom.

Cov kev hloov pauv ntawm tus nqi no tuaj yeem sau tau raws li hauv qab no:

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

•Shielded Hlau Arc Vuam (SMAW) 3-5 lb/hr

•Gas Hlau Arc Vuam (GMAW), suav nrog ob qho tib si roj-shielded thiab qhib arc vuam 5 txog 12 lb/hr

•Oxyfuel Welding (OFW) 5-10 lb/hr

Yog tias koj xav kawm ntxiv txog txoj kev nyuaj, kev siv, lossis nrhiav kev sab laj, hu rau zzbetter carbide .
