Cov kev tshaj lij kev xav tau rau welded kav tsuas yog suav nrog cov hauv qab no:
Yuav tsum ntsuas cov txheej txheem vuam: ua ntej vuam cov raj xa dej, cov vuam sib koom ua ke ntawm cov raj xa khoom kom muaj kev nyab xeeb ntawm cov raj xa dej. Cov txheej txheem vuam ntawm cov kav hlau hlau yuav tsum ua raws cov cai vuam thiab cov qauv ntawm JB4708, thiab cov kav dej ua los ntawm cov qauv kev sib tw yuav tsum ua raws li cov qauv vuam.
Kev tsim nyog ntawm Vuam cov neeg ua haujlwm: cov neeg ua haujlwm uas ua cov raj xa dej yuav tsum muaj kev tsim txuj ci thiab muaj kev txawj ntse. Vuam cov neeg ua haujlwm uas tsis yog los ntawm chav tsev tsis tuaj yeem raug ntiav nyob ntawm yuav.
Cov Kev Vuam Hlau: feem ntau siv vuam txoj kev sib tw muaj xws li sand ntawm arc vuam thiab carbon dioxide gas tiv thaiv vuam vuam. Los ntawm txhais tes arc vuam feem ntau siv rau vuam ntawm sab nraum zoov pipelines vim tias nws cov khoom siv tau thiab cov khoom siv tsawg.
Vuam cov ntaub ntawv thiab khoom siv: xaiv cov khoom siv vuam tsim nyog thiab khoom siv yog tus yuam sij los ua kom ua kom zoo. Piv txwv li, siv cov roj sib xyaw (xws li ar + co2 sib xyaw sib xyaw 80% :20%) tuaj yeem ua rau lub vuam arc ntau ruaj khov thiab txo lub ntsej muag.
Yuav tsum tau them nyiaj rau cov lus qhia: thaum muaj vuam muag, Piv txwv li, txhua lub arc taw kev vuam yuav tsum tau ua txuas ntxiv ntawm 1 mus rau hauv qab los xyuas kom meej ib qho kev tsim ntawm Weld nyob tom qab.
Tom qab welding kev kho mob thiab kev tshuaj xyuas: tom qab vuam muag, tom qab siv weld, thiab ua kom paub meej, thiab kuaj kom ntseeg tau tias tsis muaj qhov tsis xws luag lossis tawg rau ntawm qhov chaw vuam. Welded yeeb nkab yuav tsum tau tshuaj xyuas los ntawm cov kws tshaj lij thiab tsuas siv tau yog tias nws ua tau raws li cov qauv hauv tebchaws.
