Vuam & nplaim taws txiav cov txheej txheem rau corten steel
Vuam Corten Hlau
• Txoj kev: Siv cov smag (stick vuam), GMaw (MIG), lossis FCAW nrog txuam hluav taws xob hlau electrodes (piv txwv li, e7018-w lossis ER70s-3).
• Cov kauj ruam tseem ceeb:
1. Ntxuav saum npoo (tshem tawm mill nplai / xeb).
2. Theheat (yog tuab> 20 hli; 150-200℃kom tsis txhob tawg).
3. Weld nrog cov pas nrig hydrogen tsawg.
4. Tso rau ntuj patina mus kho dua tshiab tom qab-weld (tsis tas yuav pleev xim).
Nplaim Txiav Corten
• Txheej txheem: Siv cov tshuaj oxy-roj (acetylene lossis propane).
• Cov kauj ruam:
1. Kos cim txiav kab.
2. Preheat rau ~ 900℃(Cherry liab).
3. Txiav nrog lub nplaim hluav taws nruab nrab; Kev nrawm nrawm dua li cov roj carbon hlau (corten cov khoom sib txuam tiv thaiv oxidation).
4. Gr zom cov npoo kom tshem tawm slag.
Tom qab ua:
• Cia kev txiav / welded huab cua huab cua ib txwm; Patina yuav kho tus kheej kom zoo.
Nco tseg: Corten cov khoom sib phim me me hlau hauv cov ntaub npog tab sis xav tau kev kho me me rau oxidation tsis kam.
