ERW Tubetxoj kev loj hlob zeem muag thiab ntsib teeb meem

Resistance vuam yog luv luv ntawm ERW steel yeeb nkab nrog ntau qhov zoo, xws li cov khoom lag luam siab, tus nqi qis, qhov tseeb qhov tseeb, zoo nkauj zoo nkauj.Txawm li cas los xij, yav dhau los, vim kev ntseeg tsis zoo ntawm cov welding, kev txwv loj ntawm kev siv.Kev faib ua feem ntawm cov yeeb nkab me me.

ERW steel yeeb nkab vuam tshuab ua tau zoo siab rau kev ua tiav, thiab qhov kev xav no yog ib qho kev qhia ua kom zoo.Tsis siv neeg tswj tshuab ua kom zoo dua qhov tsis tau muab los xyuas kom meej qhov vuam zoo zoo heev;vim kev txhim kho ntawm ultrasonic nrhiav kom tau technology, ultrasonic flaw detector Wong pawg kab nrhiav kom tau tiav nyob rau hauv cov kab ntau lawm;vim kev txhim kho ntawm qib ntawm automation.Lub annealing ntawm weld (normalizing) kev kho cov kauj ruam hauv cov kab ntau lawm.Kev txhim kho weld kev ua tau zoo.

Saum toj no ntau yam kev siv, zoo heev txhim khu kev ntseeg ntawm ERW steel yeeb nkab welds.Ua rau nws nce ntau yam kev siv.Tam sim no, qee lub ntiaj teb kev tsim khoom ntawm ERW steel kav yeeb nkab cog tuaj yeem siv rau hauv qhov chaw txias, thiab ntau lub teb chaws tau tsim ERW yeeb nkab ntau lawm kab.

Los ntawm cov teb chaws ERW yeeb nkab ntau lawm, ntxiv rau qhov ua tau zoo ua ntej, qis rau hauv kev phais, qhov tseeb ntawm sab nraud, lub zog tensile ntawm cov vuam.Elongation tawm thiab shrinkage, dabtsi yog khoov kuaj ntawm chav tsev kub qhov cuam tshuam toughness qhov tseem ceeb tuaj yeem ua tau raws li qhov yuav tsum tau ua.Tab sis muaj ntau tus neeg tsim khoom ntawm ERW steel yeeb nkab welds tsis zoo-kub toughness, uas txwv tsis pub lawv siv hauv qhov chaw txias.

Tus nqi ntawm cov khoom siv hluav taws xob, qhov vuam ceev, lub kaum sab xis sib txuas thiab lwm yam cuam tshuam nrog qhov kub tsis tshua muaj zog ntawm cov vuam, ntau cov haujlwm tseem ceeb tau ua tiav hauv qhov no.Weld ntawm ob sab ntawm vuam nto ceev yuav tsum nyob ze rau ib leeg nyob rau hauv lub molding txheej txheem, txias welding, thiab weld ob, vim hlau yaj yog poured rau saum npoo sib cais ceev, xws li lub qub ceev tshwm sim yog hais tias tom kawg ceev yog. loj yuav ntau tus neeg txawv teb chaws ntxeem tau FATT tus nqi nce, cov ntaub ntawv pom zoo convergence lub kaum sab xis ntawm 5 mus rau 6. Zoo dua vuam ceev mus rau 20m / min tej xwm txheej tshwj xeeb tsom xam, Kuv ntseeg hais tias tom qab ob peb qhov kev ntsuam xyuas mus nrhiav qhov zoo tshaj plaws welding txheej txheem, yog li txhim kho qhov tsis tshua muaj kub toughness. ntawm weld.
