308 welding pas nrig yog ib qho siv electrode rau vuam stainless hlau. Nws yog tsim tshwj xeeb rau vuam stainless hlau hom 304L, 321, thiab 347. Cov electrode no yog tsim los ntawm kev sib xyaw ntawm chromium thiab npib tsib xee los tsim cov vuam zoo uas tiv taus cua sov, corrosion, thiab tawg.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm 308 vuam pas nrig yog tias nws tuaj yeem siv tau hauv AC thiab DC + polarity. Qhov no ua rau nws muaj ntau yam zoo kawg thiab tsim nyog siv rau hauv ntau yam kev siv vuam. Tsis tas li ntawd, nws cov ntsiab lus carbon tsawg ua kom cov welds muaj kev tiv thaiv zoo rau carbide nag lossis daus thiab intergranular corrosion.
Lwm qhov kom zoo dua ntawm qhov vuam pas nrig yog tias nws muaj qhov sib luag, uas txhais tau hais tias nws ua kom tsawg dua thiab tsim cov vuam vuam. Cov pas nrig kuj tseem siv tau rau txhua txoj haujlwm, ua rau nws xaiv zoo rau kev siv vuam siv lub taub hau lossis ntsug pob qij txha.
308 vuam pas nrig feem ntau yog siv rau hauv ntau yam lag luam, xws li kev lag luam khoom noj thiab dej haus, kev ua tshuaj, thiab tshuaj. Nws kuj tseem siv rau hauv kev tsim cov kav dej, qhov uas nws yog qhov tseem ceeb kom muaj qhov zoo thiab ruaj khov. Tsis tas li ntawd, tus pas nrig yog siv dav hauv kev kho thiab tu cov tshuab, khoom siv, thiab cov qauv uas yuav tsum tau muaj zog vuam.
Hauv kev xaus, 308 vuam pas nrig yog cov khoom siv hluav taws xob zoo uas muaj ntau yam thiab siv tau yooj yim hauv ntau daim ntawv thov vuam. Nws xa cov khoom zoo, corrosion-resistant welds uas haum rau siv nyob rau hauv ntau yam lag luam. Nws cov yam ntxwv, xws li nws cov arc du, cov ntsiab lus carbon tsawg, thiab txhua txoj haujlwm vuam muaj peev xwm, ua rau nws xaiv qhov kev xaiv zoo rau vuam stainless hlau.
