Puas yog qhov weldability ntawm galvanized coils yuav txo qis tom qab qhov chaw oxidized?

1.Dab tsi yog qhov tseem ceeb ntawm cov xeb dawb ntawm weldability?

Mechanism: Dawb xeb yog ntxeem tau thiab absorbs thiab khaws noo noo los ntawm huab cua. Nyob rau hauv lub instantaneous kub kub ntawm lub vuam arc, no ya raws evaporates sai sai rau hauv dej vapor. Ib txhij, cov xeb dawb nws tus kheej (ZnCO₃·Zn(OH)₂) decomposes los tsim CO₂ thiab H₂O.

Qhov tshwm sim: Cov pa roj no, tsis tuaj yeem khiav tawm ua ntej lub pas dej molten sai txias thiab solidifies, ua rau hauv cov hlau weld, tsim cov porosity ntom. Porosity ua rau txo cov ntoo khaub lig zoo- ntu ntu ntawm qhov vuam, ua rau lub zog poob qis, tawv, thiab lub neej qaug zog.

2.Dab tsi yog qhov cuam tshuam ntawm cov tuab thiab tuab oxide txheej lossis xeb liab ntawm weldability?

Cov porosity hnyav heev thiab slag suav nrog: Cov txheej oxide tuab qhia txog cov pa roj thiab impurities loj heev, ua rau nws tsis tuaj yeem ua tiav qhov ntom ntom ntom. Lub weld yuav muaj cov pores thiab slag inclusions.

Weld tsis zoo heev: Cov welds zoo li no yuav luag tsis muaj cov khoom siv kho tshuab thiab sawv cev rau qhov tsis zoo ntawm cov qauv, yuav tsum tau muab tshem tawm thiab rov ua dua - vuam.

Tawg zinc plating: Lub sijhawm no, cov txheej txheem zinc zoo ntawm qhov chaw tau raug rhuav tshem, thiab thaj chaw welded tau poob cov txiaj ntsig tiv thaiv corrosion ntawm zinc plating.

3.Dab tsi yog qhov tsis zoo ntawm substrate xeb (liab xeb) ntawm weldability?

Hlau oxides tsis yog - conductive, nyuaj rau yaj, thiab tsim roj. Qhov hnyav slag suav nrog thiab porosity tiv thaiv kev tsim vuam.

4.Dab tsi yog cov kauj ruam koom nrog hauv kev tu txhua yam?

Cov cuab yeej: Lub kaum sab xis grinder

Accessories:

Bowl-zoo li tus txhuam hniav: Tsim nyog rau kev tu lub tiaj tiaj thiab welds.

Abrasive log / louvered blades: Rau cov tuab oxide txheej los yog xeb liab, yuav tsum muaj cov hniav ntau dua.

Standard: Sib tsoo kom txog thaum lub npoo muaj cov xim hlau zoo nkauj, tsis muaj xim dawb lossis xim liab.

 

5.Yuav ua li cas ntxuav nws?

Tshem tawm tag nrho cov plua plav nrog cua compressed.

Yog tias tsim nyog, so nrog acetone los yog ib lub tshuab ntxuav tshwj xeeb kom tshem tawm cov roj lossis roj uas tseem tshuav.
