Welded steel yeeb nkab, tseem hu ua welded yeeb nkab, yog cov yeeb nkab steel ua los ntawm vuam hlau phaj los yog cov hlau tsoo tom qab raug cross. Cov txheej txheem ntau lawm ntawm welded steel yeeb nkab yog qhov yooj yim, muaj ntau ntau yam kev ua haujlwm siab, muaj ntau yam thiab cov khoom siv tau me me.
Txij li thaum 1930s, nrog kev txhim kho nrawm nrawm ntawm kev tsim khoom zoo nkauj thiab tshuaj xyuas cov tshuab welded, thiab cov khoom siv tshuaj ntsuam xyuas tau nce ntxiv, thiab tau hloov cov leeg ntawm cov yeeb nkab. Welded steel yeeb nkab tau muab faib ua kev sib khi ncaj Welded yeeb nkab thiab kauv welded yeeb nkab raws li daim foos ntawm Weld.
Cov txheej txheem ntau lawm ntawm txoj kev ncaj Welded yeeb nkab Welded yeeb nkab yog yooj yim, tus nqi ntau, thiab txoj kev loj hlob yog nrawm. Lub zog ntawm cov kauv welded kav yog feem ntau siab dua li ntawd ntawm kev sib tw ncaj welded kav. Welded kav dej uas muaj lub diameaters loj dua tuaj yeem tsim los ntawm kev txo cov nqi. Welded kav nrog cov kab sib txawv kuj tseem tuaj yeem tsim nrog cov nqi ntawm tib qhov dav. Txawm li cas los xij, piv nrog ncaj seam kav dej ntawm tib qhov ntev, lub ntev weld ntev yog nce los ntawm 30 txog 100%, thiab cov ceev ntau dua. Yog li ntawd, qhov me-diam welded kav yog feem ntau seam welded, thiab cov kab loj heev welded.
