Muab kauv submerged arc welded steel yeeb nkab qee zaum ntsib qee qhov xwm txheej hauv cov txheej txheem ntau lawm, xws li cov txheej txheem ntau lawm, xws li cov txheej txheem ntau lawm, xws li cov txheej txheem ntau lawm, xws li cov txheej txheem ntau lawm Thaum muaj cua qhov nyob rau hauv lub vuam sib khi, nws yuav cuam tshuam qhov zoo ntawm cov raj xa dej, ua kom cov raj xa dej thiab ua rau poob hnyav. Thaum cov yeeb nkab steel siv, nws tseem yuav ua rau corrosion vim lub hav zoov ntawm huab cua lub sijhawm thiab luv luv lub sijhawm pabcuam ntawm cov yeeb nkab. Qhov feem ntau ua rau ntawm huab cua qhov hauv kauv steel yeeb nkab willing cov dej flux lossis qee cov av hauv cov qhov vuam, uas yuav ua rau huab cua. Txhawm rau tiv thaiv qhov no, yuav tsum xaiv cov sib npaug flux muaj pes tsawg leeg kom thiaj yuav tsis muaj qhov hws vuam.
Thaum vuam, qhov tuab ntawm ham kev nce khoom yuav tsum yog nruab nrab ntawm 25 thiab 45. Txhawm rau tiv thaiv cov pa hlau hluav taws, cov npoo hlau yuav tsum kho. Thaum lub sij hawm vuam, tag nrho cov av ntawm cov phaj steel yuav tsum tau muab cov tshuaj tiv thaiv ua ntej los tiv thaiv lwm yam kev sib tw los ntawm kev siv lub tshuab vuam thiab tsim cov cua hauv lub sijhawm vuam.
