1. Galvanized steel kav uas muaj lub taub yeeb nkab loj dua 100 hli yuav tsum txuas nrog flanges lossis ferrule-hom tshwj xeeb cov yeeb nkab.
2. Txhawm rau txhawm rau xyuas kom lub vuam zoo, cov kav hlau galvanized steel thiab flanges yuav tsum tau galvanized, thiab galvanized txheej yuav tsum tau kho nrog lub tes log lossis ntawv pleev xim, lossis txheej galvanized yuav tsum tau muab tshem tawm nrog lub ntsej muag roj gas.
3. Lub weld ntawm galvanized steel yeeb nkab thiab flange yuav tsum tau galvanized ob zaug.
Kev ntsuas kom ntseeg tau welding zoo nrog
1. Tib neeg qhov zoo tshaj yuav yog lub ntsiab lus tseem ceeb tswj rau vuam roj galvanized kav. Vim tias tsis muaj qhov tsim nyog tom qab-weld kev tswj hwm, nws yooj yim rau kev txiav cov ces kaum thiab cuam tshuam rau qhov zoo; tib lub sijhawm, vuam tshwj xeeb ntawm cov yeeb nkab galvanized ua rau nws nyuaj rau kom ntseeg tau lub vuam zoo. Yog li ntawd, ua ntej pib ua haujlwm, nws yog qhov yuav tsum tau xaiv cov kws tshaj lij txuas nrog lub rwj sib txuas thiab lub nkoj siab lossis cov ntawv pov thawj sib tw rau lub ntsej muag, ua cov kev cob qhia kev tsim nyog thiab kev qhia meej, thiab ua qhov txuas ntawm chaw xa khoom xaib thiab kev pom zoo raws li boiler siab siab txog ntsha lub nkoj. kev ntsuam xyuas cov cai, thiab tom qab ntawv tso cai Cov Ntawv Tso Cai nkag mus rau qhov chaw rau vuam. Thiab tsis hloov ntawm qhov yuav, kom ntseeg tau tias tus hlau txuas hlau txuas ntawm lub raj xa dej kuj tseem ruaj khov.
2. Kev tswj hwm cov khoom noj khoom haus welding: xyuas kom meej tias cov khoom siv vuam siv uas yuav los ntawm cov kem niaj zaus muaj cov ntawv pov thawj zoo thiab cov ntawv pov thawj uas ua tau raws li cov txheej txheem xav tau; vuam cov khoom siv yuav tsum raug kuaj xyuas thiab tau txais thiab xa thiab tsim cov txheej txheem thiab ua tiav, thiab cov taub hau vuam yuav tsum tau rov ua dua tshiab thiab tswj nruj me ntsis kom ntseeg tau tias cov kev taw qhia ntws, Dosage: Welding siv tau yuav tsum tau muab ci raws li tus txheej txheem, thiab tus nqi ntawm vuam cov khoom siv yuav tsum tsis pub ntau tshaj ib nrab sijhawm hauv ib zaug.
3. Lub tshuab vuam tshuab: Lub tshuab vuam yog cov cuab yeej siv rau vuam, uas yuav tsum ua kom ntseeg tau muaj nuj nqi thiab ua tau raws li cov kev xav tau ntawm cov txheej txheem; lub tshuab vuam yuav tsum muaj qhov tsim nyog tam sim no thiab voltmeter kom ntseeg tau tias qhov ua tiav ntawm vuam txheej txheem. Lub vuam cable yuav tsum tsis txhob ntev dhau lawm, thiab lub tshuab ntsuas vuam yuav tsum tau muab kho thaum nws ntev dua.
4. Vuam txheej txheem txheej txheem: kom paub meej nruj ua raws li cov txheej txheem tshwj xeeb kev khiav haujlwm rau cov kav dej galvanized, xyuas cov khoom siv ua ntej weld zuaj raws li cov txheej txheem vuam, tswj cov txheej txheem vuam tsis ua haujlwm, kev ua haujlwm, xyuas cov tsos zoo tom qab vuam, thiab ntxiv uas tsis yog-kuaj tom qab vuam yog tsim nyog. Tswj theem vuam thiab qhov vuam siv tau rau txhua tus hla.
5. Vuam ib puag ncig tswj: kom ntseeg tau tias qhov ntsuas kub, av noo, thiab cua ceev thaum vuam ua tau raws li cov txheej txheem yuav tsum tau ua. Tsis pub siv lub tshuab vuam tsoo thaum tsis tsim nyog.
