Khoom Taw qhia

GB / T 1591 Q345B ncaj seam submerged arc welded yeeb nkab yog ib qho ncaj seam submerged arc welded steel yeeb nkab ua raws li Suav teb chaws tus qauv GB / T 1591, qhov twg Q345B qhia cov khoom siv thiab kev ua tau zoo ntawm cov yeeb nkab steel.Q345B welded steel yeeb nkabyog ib qho qis-alloy high-strength structural steel nrog ntau zog yield zog thiab zoo mechanical zog tshaj Q345A welded yeeb nkab.
Feem ntau, cov kav dej welded yog siv los thauj cov kua dej uas tsis tshua muaj siab. Ua los ntawm Q345B steel. Nws tseem tuaj yeem ua los ntawm lwm cov hlau me me uas yooj yim weldable. Cov yeeb nkab steel yog raug rau hydraulic siab, dabtsi yog khoov, flattening thiab lwm yam kev sim, thiab muaj qee yam yuav tsum tau ua rau saum npoo zoo. Kev xa khoom ntev yog feem ntau yog 4-10m, thiab kev xa khoom ntev ntev (lossis ntau qhov ntev) feem ntau xav tau. Cov specifications ntawm welded kav yog qhia nyob rau hauv nominal txoj kab uas hla (millimeters los yog nti). Lub nominal txoj kab uas hla txawv ntawm qhov tseeb. Raws li cov txheej txheem phab ntsa thickness, muaj ob hom welded kav: zoo tib yam steel kav thiab thickened steel kav.
