Ntxuav lub hauv paus hlau Groove thiab thaj chaw ntau dua los yog sib npaug rau ob sab kom tshem tawm cov roj, nplai, xeb, thiab lwm yamNEEG KHO TSHUAB SIB TSOO (NROG RAU STALLESS HLAU SIB TSUAG LOG) + Acetone Wiping; 2. Ntxuav lub vuam hlau nrog anhydrous ethanol los tshem tawm cov roj saum npoo av |
Tiv thaiv tsis xws luag xws li porosity thiab suav thaum lub sij hawm vuam, thiab kom cov kev sib koom ua ke ntawm thaj chaw fustering rau kev cuam tshuam weld lub corrosion tsis kam |
| Kev tswj cov roj pa roj | 1. TIG (GTAW)99.99%thiab ntws tus nqi tswj hwm ntawm8-15L / min; 2. Backside Shielding: Kom tuab daim hlau lossis siab - Xav tau cov ntawv thov sib cav (hla kev sib tw 5-8l / min) lossis siv cov ceramic rov qab; 3. Mig (Gmaw): Ar + 2}% - 5%-ur ₂ sib xyaw roj (tsis txhob weld oxidation tshwm sim los ntawm cov ntshiab? |
Tiv thaiv oxidation thiab hlawv cov khoom poob ntawm alloy cov ntsiab xws li Cr thiab Ni hauv lub tsheb kub, thiab txhim kho cov weld lub corrosion tsis kam thiab tawv |
| Vuam Parameter Thaiv | 1. Tig (Gtaw): Tam sim no80-150A, Volion10-14V, vuam ceev50-100mm / min; 2. MIG (GMAW): Tam sim no120-200A, Volion18-24V, ceev80-150mm / min; 3. Xyaum tswj cov lus tawm thaum tshav kub kom tsis txhob muaj kev kub ntxhov (cuam tshuam qhov kub tsawg dua lossis sib npaug150 Qib) |
Tiv thaiv cov grain coarsening tshwm sim los ntawm tshav kub ntau dhau, uas txo tus weld qhov kev cuam tshuam nyuaj; Zam kev tsim ntawm thaj chaw rhiab (450- 850 degree) nyob rau hauv lub hauv paus-cuam tshuam hlau, uas triggers intergranular corrosion |
| Preheating & post -} Cov cua sov yuav tsum muaj | 1. Tsis muaj qhov yuav tsum muaj nyob rau hauv ib txwm muaj (phaj tuab tsawg dua los yog sib npaug rau 20mm, huab cua kub siab tshaj lossis sib npaug 0 degree); 2. Thaum Phaj Thickness> 20mm lossis ambient kub <0 degree, preheating kub tsawg dua los yog sib npaug150 Qib(kom tsis txhob mob carbide nag los tshwm sim los ntawm cov kub kub); 3. Tsis muaj ib txwm ua tshaj tawm -}}}}}}}}}}}}}}}}} € wel requir (requir requir requir requir requir requir requir requir requir requir requir requir requirT, thiab qhov ntsuas kub yuav tsum tau tswj hwm qis dua 250 degree) |
Tiv thaiv kev tawg txias thaum qis -} kub vuam; Zam kev ua kom muaj txiaj ntsig ntawm cov hlau ua kom muaj ntau dua |
| Vuam cov ntsiab lus | 1. Txais yuavLuv - arc vuam, tswj lub arc ntev txog 1-2 zaug lub taub kom txo cov khoom siv hlawv alloy. 2. For multi-layer and multi-pass welding, clean the weld pass promptly after each pass and control the interpass temperature<=150℃; 3. Zam kev siv Oscillation (oscillation ntau dua li lossis sib npaug rau 3 zaug ntawm cov kab hlau), thiab qhov ua ntej nqaim-}}}}}}}}}}}}}}}}}}}}} dhau vuam |
Txo cov tswv yim cua sov thiab kev pheej hmoo ntawm cov pas dej oxidation; xyuas kom meej cov qauv weld tsim thiab zam kom tsis txhob muaj xws li kev ua tsis tiav thiab tsis tiav kev nkag mus |
| Post -} Weld Kho | 1. Tam sim ntawd ntxuav lub weld deg npoo slag thiab taw nrog lub stainless hlau txhuam tom qab vuam, thiab yaug nrog dej huv; 2. Rau cov xwm txheej nrog cov kev ua tau zoo heev yuav tsum muaj,Kev Kho Mob Passivationyog qhov tsim nyog (piv txwv li, so rau hauv 20% -30% nitric acid daws rau 15-30 feeb, lossis thov tshwj xeeb passive muab tshuaj txhuam); 3. Zam kev tu cov cuab yeej weld nrog cov cuab yeej steel (tiv thaiv cov hlau ion paug) |
Tshem tawm cov dej paug saum npoo av thiab ntsuas phoo, rov qab muab cov duab Weld passivation zaj duab xis (crreso₃), thiab txhim kho ntau dua corrosion resistance; Tiv thaiv kev corrosion hauv nroog los ntawm cov hlau ion embedding |
| Kev tiv thaiv kev nyab xeeb | 1. Tswj kev nyab xeeb zoo nyob hauv qhov chaw vuam thiab hnavLub ntsej muag plua plav (kom tiv thaiv kom tsis txhob nqus tau ntawm CR thiab Ni cov fumes); 2. Hnav Arc - Cov ntsiab phob npog ntsej muag, nplaim taws- hnab looj tes ua haujlwm; 3. Zam kev nkag siab ncaj qha ntawm vuam fumes; Siv cov tso pa hauv zos yog tias tsim nyog |
Vuam fumes ntawm E316L muaj cov tshuaj lom xws li CRRE, yog li nws yog ib qho tsim nyog los tiv thaiv kev phom sij rau kev ua haujlwm; Zam kev tawv nqaij thiab qhov muag kub muag los ntawm arc teeb |
