Feem ntau siv vuam steel kav yog muab faib ua peb hom txheej txheem vuam siv thaum lub sij hawm tsim khoom.
① Nruam rauv welding (forging welding) steel yeeb nkab: Nws yog tus cwj pwm los ntawm kev ua haujlwm siab thiab cov nqi tsim khoom tsawg, tab sis cov vuam sib koom ua ke tsis tiav, qhov vuam zoo tsis zoo, thiab kev ua haujlwm zoo txhua yam tsis zoo.
② Resistance vuam steel yeeb nkab: Nws yog tus cwj pwm los ntawm kev ua haujlwm siab, qib siab ntawm automation, thiab tsis tas yuav vuam thiab vuam thaum vuam. Kev puas tsuaj rau cov khoom siv hauv niam yog me me, thiab qhov deformation thiab residual stress tom qab vuam kuj yog me me. Txawm li cas los xij, nws cov cuab yeej tsim khoom yog qhov nyuaj dua, cov cuab yeej siv cuab yeej cuab tam yog siab, thiab qhov kev xav tau ntawm qhov sib koom ua ke yog qhov siab.
③ Arc welded steel yeeb nkab: Nws yog tus cwj pwm los ntawm kev sib koom ua ke kom ua tiav cov khoom siv hlau ua tiav, thiab kev ua haujlwm ntawm kev sib koom ua ke tuaj yeem ua tiav lossis ua tiav cov khoom siv ntawm niam cov khoom. Nyob ntawm cov duab ntawm cov welded, lub arc welded steel yeeb nkab yuav muab faib ua ob hom: ncaj slit yeeb nkab thiab kauv welded kav. Raws li cov kev tiv thaiv thaum lub sij hawm vuam, lub arc welded steel yeeb nkab yuav muab faib ua faus arc welded steel kav thiab melting polar gas tiv thaiv. Muaj ob hom vuam steel kav.
