Cov txheej txheem sib txawv ntawm ncaj seam steel yeeb nkab thiab kauv steel yeeb nkab:
1. Los ntawm kev pom zoo: ncaj seam steel yeeb nkab yog steel phaj ntawm ib qho dav uas yog khoov rau hauv ib lub raj thiab ces welded los ua nws. Muaj tsuas yog ib qho weld nyob rau hauv nruab nrab ntawm lub ncaj seam steel yeeb nkab. Cov cuab yeej siv tau yooj yim thiab cov khoom tsim tau siab. Kauv steel hlab yog tsim los ntawm dov steel daim hlau ntawm ib tug tej yam dav rau hauv ib lub tog raj kheej thiab ces welding lawv ua ke los tsim. Nws yog tsim los ntawm ob-sided submerged arc vuam. Cov cuab yeej siv tau yooj yim dua. Nyob rau tib lub sij hawm, vim hais tias cov weld yog ntev npaum li cas ntawm cov ncaj seam steel yeeb nkab, cov khoom tsim tau kuj tsawg.
2. Los ntawm qhov kev xav ntawm lub zog: tom qab longitudinal seam steel yeeb nkab yog welded, nws cov kev ntxhov siab sab hauv yog muab faib raws li weld seam, thaum lub zog sab hauv ntawm kauv steel yeeb nkab tom qab vuam Nws yog sib npaug faib rau hauv axial thiab radial cov lus qhia, uas tuaj yeem ua tau zoo dua ib feem. compensate lub siab nws dais. Yog li ntawd, cov kauv steel yeeb nkab muaj zog dua nyob rau hauv cov nqe lus ntawm kev ua haujlwm siab.
Lub tswv yim: Ncaj seam steel yeeb nkab yog cov yeeb nkab steel uas nws qhov vuam seam yog sib npaug mus rau qhov ntev ntawm cov yeeb nkab steel. Ncaj seam steel yeeb nkab tuaj yeem muab faib ua ntau zaus ncaj seam (ERW) steel yeeb nkab thiab submerged arc welded (LSAW) ncaj seam steel yeeb nkab raws li cov txheej txheem ntau lawm. Ncaj seam welded yeeb nkab muaj cov txheej txheem tsim khoom yooj yim, kev ua haujlwm siab ntau lawm, tus nqi qis thiab kev loj hlob sai.
ERW welded yeeb nkab yog tsim los ntawm dov ib txoj hlua thiab vuam cov seam, nrog nruj dua qhov ntev thiab qhov hnyav dua. Weld seam yog kho cua sov tom qab vuam kom tsis muaj qhov tsis muaj martensite nyob, thiab vuam flash tuaj yeem tshem tawm ntawm ob sab hauv thiab sab nraud.
