Welded steel yeeb nkab yog seamed steel yeeb nkab. Nws cov khoom yog khoov lub raj dawb paug (steel phaj thiab steel sawb) rau hauv ib lub raj uas yuav tsum tau hla-sectional duab thiab loj los ntawm ntau txoj kev sib sau, thiab ces siv sib txawv vuam txoj kev los welding weld seam ua ke. Cov txheej txheem tau txais cov kav hlau. Piv nrog seamless steel yeeb nkab thiab welded yeeb nkab, nws muaj cov yam ntxwv ntawm cov khoom siab precision, tshwj xeeb tshaj yog cov phab ntsa thickness precision, yooj yim cov cuab yeej tseem ceeb, me me hneev taw, nruam kev lag luam hauv ntau lawm, hloov tau ntau lawm, thiab ntau yam khoom ntawm chav tsev.
Ncaj seam high-frequency welded yeeb nkab (ERW) yog kom sov thiab yaj lub ntug ntawm lub raj billet los ntawm kev siv cov nyhuv ntawm daim tawv nqaij thiab qhov sib thooj nyhuv ntawm high-frequency tam sim no tom qab kub-dov coil yog tsim los ntawm lub tshuab tsim, thiab lub siab. welding yog nqa tawm nyob rau hauv qhov kev txiav txim ntawm extrusion roller kom ua tiav ntau lawm.
Welded steel yeeb nkab, tseem hu ua welded yeeb nkab, yog cov yeeb nkab steel ua los ntawm steel phaj los yog sawb hlau tom qab crimping thiab vuam. Welded steel yeeb nkab muaj cov txheej txheem tsim khoom yooj yim, kev ua haujlwm siab ntau lawm, ntau yam thiab cov lus qhia tshwj xeeb, thiab cov cuab yeej siv tsawg dua, tab sis nws lub zog dav dav yog qis dua li ntawm seamless steel yeeb nkab.
Txij li thaum xyoo 1930, nrog rau kev txhim kho sai ntawm kev sib txuas ua ke ntawm cov hlau zoo thiab kev nce qib ntawm vuam thiab tshuaj xyuas tshuab, qhov zoo ntawm welds tau raug txhim kho tas li, thiab ntau yam thiab cov ntsiab lus ntawm cov kav hlau welded tau nce ib hnub dhau ib hnub. . Seam steel yeeb nkab. Welded steel kav yog muab faib ua ncaj seam welded kav thiab kauv welded kav raws li daim ntawv ntawm weld seam.
Kev faib tawm los ntawm cov txheej txheem ntau lawm: txheej txheem kev faib tawm - arc welded yeeb nkab, hluav taws xob tiv thaiv welded yeeb nkab, (siab zaus, tsis tshua muaj zaus) roj welded yeeb nkab, rauv welded yeeb nkab. Cov txheej txheem ntau lawm ntawm txoj kab ncaj nraim welded yeeb nkab yog qhov yooj yim, qhov kev ua tau zoo yog siab, tus nqi qis, thiab kev loj hlob sai. Lub zog ntawm cov kauv welded yeeb nkab feem ntau siab tshaj qhov ncaj seam welded yeeb nkab, thiab cov yeeb nkab welded nrog ib txoj kab uas hla loj tuaj yeem ua tau nrog cov kab nqaim, thiab cov kav hlau txuas nrog cov kab sib txawv tuaj yeem tsim nrog tib qhov dav dav. Tab sis piv nrog cov yeeb nkab ncaj seam ntawm tib qhov ntev, qhov ntev ntawm vuam yog nce los ntawm 30 ~ 100%, thiab qhov ceev ntau lawm yog qis dua.
