Kauv welded yeeb nkabyog ib qho tseem ceeb nyob rau hauv ntau yam lag luam xws li roj thiab roj, kev tsim kho thiab dej infrastructure.Cov kav dej yog tsim los siv cov txheej txheem tshwj xeeb hu ua kauv welding, uas koom nrog kev sib koom ua ke ntawm cov hlau los tsim ib qho kev sib txuas txuas ntxiv.Txoj kev tsim khoom no muaj ntau yam zoo, nrog rau lub zog siab, durability thiab nqi-zoo.Tsis tas li ntawd, kauv welded kav ua raws li cov qauv thoob ntiaj teb xws li EN10219 kom ntseeg tau tias lawv zoo thiab ua haujlwm tau zoo.
TS EN 10219yog tus qauv European uas qhia txog cov txheej txheem kev xa khoom rau cov khoom txias-tsim welded structural hollow seem ntawm cov hlau tsis-alloy thiab nplua-grained steel.Cov txheej txheem no qhia txog qhov yuav tsum tau ua rau cov txheej txheem tsim khoom, cov khoom siv thiab qhov ntev ntev ntawm cov kav welded steel kav kom ntseeg tau tias lawv tsim nyog rau kev siv cov qauv.
Kev tsim cov kauv welded steel kav thawj zaug xaiv cov hlau coils zoo, thiab tom qab ntawd uncoils thiab pub rau hauv lub tshuab kauv vuam.Lub tshuab siv cov txheej txheem txuas txuas txuas ntxiv mus koom nrog cov npoo ntawm cov hlau sawb, tsim kom muaj cov hlua khi ntawm cov kav ntev.Tom qab ntawd cov welds raug kuaj xyuas kom tsis muaj kev puas tsuaj los xyuas kom meej tias lawv muaj kev ncaj ncees thiab lub zog.Tom qab vuam, cov kav dej tau dhau los ua ntau yam txheej txheem tiav, suav nrog sizing, straightening thiab tshuaj xyuas, kom ua tau raws li cov cai ntawm EN10219.
Ib qho ntawm qhov zoo tshaj plaws ntawm kauv welded steel yeeb nkab yog nws lub peev xwm los tiv taus siab sab hauv thiab sab nraud, ua rau nws tsim nyog rau kev thauj cov kua thiab roj hauv ntau yam lag luam.Tsis tas li ntawd, cov txheej txheem muab kauv vuam tuaj yeem tsim cov kav dej hauv ntau txoj kab uas hla thiab tuab, muab kev tsim thiab kev tsim kho yooj yim.Cov kav dej no tseem tiv taus corrosion, uas ntxiv dag zog rau lawv lub neej ntev thiab kev ua tau zoo hauv qhov xav tau ib puag ncig.
Ua raws li EN10219 yog qhov tseem ceeb los xyuas kom meej qhov zoo thiab kev ntseeg siab ntawm cov kav hlau welded steel kav.Tus qauv tsim cov kev cai nruj rau cov khoom muaj pes tsawg leeg, cov khoom siv kho tshuab thiab qhov ntev ntev kom ntseeg tau tias cov kav dej ua tau raws li cov qauv kev ua haujlwm uas yuav tsum tau ua rau kev siv cov qauv.
Tsis tas li ntawd, EN10219 tseem qhia txog cov txheej txheem kuaj thiab ntawv pov thawj uas cov tuam txhab tsim khoom yuav tsum ua raws, suav nrog kev sim tsis muaj kev puas tsuaj ntawm welds, kev ntsuas kev ua haujlwm thiab kev tshuaj xyuas pom.Los ntawm kev ua raws li cov qauv nruj no, cov tuam txhab tsim khoom tuaj yeem muab cov neeg siv khoom zoo thiab ua haujlwm tau lees paub ntawm kauv welded steel yeeb nkab.
Hauv cov ntsiab lus, kev tsim khoom thiab cov qauv rau cov kav hlau txuas txuas tau teev tseg hauv EN10219 ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau thiab ua haujlwm ntawm cov khoom tseem ceeb no.Los ntawm kev siv cov txheej txheem kauv vuam thiab ua raws li cov qauv kev tsim khoom nruj, cov tuam ntxhab tuaj yeem tsim cov yeeb nkab zoo uas ua tau raws li qhov xav tau ntawm ntau yam kev lag luam.Raws li qhov tshwm sim, EN10219 dhau los ua lub hauv paus tseem ceeb rau kev tsim khoom, kev sim thiab ntawv pov thawj ntawm cov kav hlau welded steel kav, ua rau lawv siv dav hauv kev tsim kho vaj tse thiab kev tsim kho thoob ntiaj teb.
