Nyob rau hauv feem ntau zoo - tswj vuam science: tsis muaj kev txhim kho txheej txheem tshwj xeeb yog xav tau
Ua ntej - Weld Deg Npaj: Ua kom huv si Weld cheeb tsam thiab ib thaj chaw nyob ib sab (feem ntau 20-30mm ntawm ob tog ntawm pob qij txha, kom tshem tawm cov roj, roj, pleev xim, xoob xoob, lossis nplai. Cov khoom tsis huv nyob rau sab saum npoo uas tuaj yeem cuam tshuam nrog Weld fusion thiab cuam tshuam rau kev tsim cov khaub ncaws hnav ntawm lub patina.
Kev siv ntawm cov huab cua sib txuam sib txuas hlau vuam siv: Ua haujlwm vuam hlau, electrodes, lossis fluxes zoo nkauj tshwj xeeb rau S355j2W (piv txwv li}} alloy _} Cov ntsiab lus tseem ceeb rau PATINY tsim). Mismatched consumables (piv txwv li, cov qauv roj carbon mon electrodes) yuav ua rau muaj kev siv hlau weld nrog cov huab cua tsis zoo, xav tau kho.
Post -} weld tu: Tom qab vuam, tshem tawm slag, nti, thiab ib qho vuam fumes / seem ntawm cov tshuab sib tsoo lossis cov log sib tsoo) lossis lub teeb colling. Qhov no ua rau cov kab mob huv si, tsis muaj chaw ntawm Weld thiab Haz, tso cai rau Patina los pib ua tusyees.
Thaum xeb txheej txheej kho txheej txheem kev kho mob ua qhov tsim nyog
Weld weld nto kev sib kis lossis tsis xws luag: Yog tias tus weld yog paug nrog roj, noo noo, lossis yog tias swb (cov kab nrib pleb Cov pob no yuav corrode preforently, tsim "pits" lossis undermining kev sib koom ua ke txoj kev ncaj ncees.
Overheating lossis tsis muaj zog ua kom sov: Ntau dhau vuam cua sov tuaj yeem sib xyaw ntawm microstructure ntawm lub microstructure ntawm microstructure ntawm microstructure ntawm microstructure ntawm microstructure ntawm microstructure ntawm cov peev xwm los khaws cov khoom siv patey. Hauv cov xwm txheej hnyav, nws tseem tuaj yeem hlawv cov patina ntawm lub hauv paus hlau uas nyob ib sab rau cov hlau, tawm hauv cov hlau liab uas tsis muaj xeb.
Kev puas tsuaj rau lub hauv paus hlau ua ntej -} twb muaj lawm patina: Thaum vuam teeb (piv txwv li, clamping, sib tsoo) lossis vim yog qhov sib tw ntawm cov hauv paus ntawm lub hauv paus hlau yuav tau kos lossis ntxig tseg, ua rau cov hlau tshiab. Yog tias tsis muaj kev kho, cov me me me me yuav xeb tsis sib xws, cuam tshuam qhov tag nrho pitina txuas ntxiv.
Qhov chaw ua haujlwm hnyav chaw ib puag ncig: Rau cov ntawv thov hauv cov chaw corrosive horrosive (piv txwv li, cov cheeb tsam ntug dej hiav txwv uas muaj kev cuam tshuam nrog ntau rau lub sijhawm PATHAIN tuaj yeem nrawm corrosion. Nyob rau hauv cov xwm txheej zoo li no, ua suab nrov ua kom ntseeg tau qhov ntev ntawm no - tsis ua kom tsis kam.
Cov txheej txheem xeb txheej txheej rau S355j2W tom qab vuam
Neeg kho tshuab Kho: Lub teeb sib tsoo nrog cov nplua - grit sandpaper lossis xaim txhuam kom tshem cov xeb puas, lossis cov khoom tsis zoo, lossis cov khoom tsis huv. Nov yog qhov yooj yim rau cov me me, cov tsis muaj zog hauv zos.
Tshuaj Hla: Thov cov tshuaj acidic me me (piv txwv li, diluted phosphoric acid) rau etch txheej oxide txheej thiab ua kom cov hlau rau MATINE tsim. Qhov no feem ntau siv rau thaj chaw loj dua lossis thaum cov neeg kho tshuab sib tsoo yuav khawb daim hlau nyias.
Daim Ntawv Thov Kev Thov Patina Accelerator: Nyob rau lub sijhawm {- Cov phiaj xwm kev lag luam patina accelerator (ib qho kev daws teeb meem (kev daws teeb meem Qhov no nrawm dua ntawm kev tsim cov txheej xeb tiv thaiv, kom nws phim lub hauv paus hlau lub patina hauv lub lis piam ntau dua li lub hlis.
