Qhov ncaj seam steel yeeb nkab yog cov yeeb nkab steel uas muaj qhov ntev ntawm qhov sib txuas ntawm vuam seams thiab steel kav. Nws yog feem ntau muab faib ua pej xeem welding steel kav, vuam nyias phab ntsa kav, transformer txias roj kav, thiab hais txog. Cov txheej txheem ntau lawm ntawm cov kav hlau ncaj yog qhov yooj yim, kev ua haujlwm siab ntau lawm, tus nqi qis, thiab kev loj hlob sai. Lub zog ntawm cov kauv welded yeeb nkab feem ntau yog siab tshaj qhov ncaj seam steel yeeb nkab. Cov yeeb nkab welded nrog ib txoj kab uas loj loj tuaj yeem ua tau nrog lub voj voog nqaim. Cov kav hlau ntawm cov yeeb nkab sib txawv tuaj yeem tsim tau ntawm tib lub square billet dav. Qhov ntev vuam tau nce los ntawm 30% thiab 100%, feem, thiab cov khoom ceev tau qis dua.
Stranding steel tube ua ntej-welding zoo: ua ntej-welding zoo suav nrog qhov zoo ntawm cov pob qij txha thiab qhov zoo ntawm vuam.
1. Lub seam (uas yog, tsim seam) yam tsis muaj qhov yuam kev lossis qhov tsis ncaj ncees lawm ntug yog tsawg dua li tus nqi teev. Feem ntau, nws qhia tau hais tias qhov kev ua yuam kev ntug tsawg dua los yog sib npaug yog 8% ntawm lub thickness ntawm steel phaj, thiab qhov siab tshaj plaws tsis pub tshaj 1.5 hli.
2. Txhawm rau kom ntseeg tau tias cov welded seams muaj qhov tsim nyog qhov tob thiab melting npaum li cas, tsis tsuas yog nws yuav tsum xyuas kom meej tias tsis muaj tawg tom qab vuam, tsis muaj combustion, tab sis kuj tswj qhov siab ntawm vuam.
3. Welded welds tsis tu ncua thiab zoo rau molding los xyuas kom meej qhov kawg sab nraud vuam zoo.
4. Tsis muaj qhov tsis xws luag xws li vuam sib txawv, qhov pores, tawg, scum, kub hnyiab, thiab vuam qog nyob rau sab nraub qaum.
5. Tsis muaj qhov kub hnyiab, tawg me me, tsis cuam tshuam rau lub tank kawg thiab qhov chaw zoo.
6. Vuam seams phim cov khoom siv niam, thiab kev ua haujlwm ntawm lub cev thiab tshuaj lom neeg ntawm vuam hlau ua tau raws li qhov yuav tsum tau ua.
Cov txheej txheem molding ntawm kev tsim cov kav hlau loj-caliber ncaj sewing kav suav nrog rolling roller molding method (CFE), UOE molding method, CE molding, thiab lwm yam. Rau feem ntau txoj kev molding, cov txheej txheem kawg yog cov duab thiab zoo ntawm cov yeeb nkab steel tau dhau los ua ib qho tseem ceeb. txheej txheem los xyuas kom meej qhov zoo ntawm cov yeeb nkab tiav nyob rau hauv ib tug loj-caliber ncaj seam welded yeeb nkab. Txoj kab uas hla yog ib hom kev siv tshuab siab siv tshuab uas siv hydraulic los yog cov cuab yeej siv los ua kom muaj zog los ntawm cov phab ntsa sab hauv ntawm cov yeeb nkab steel los nthuav cov yeeb nkab steel raws cov kev taw qhia radial. Txoj kev siv tshuab yog yooj yim dua thiab ua tau zoo dua li txoj kev hydraulic. Nws txais cov txheej txheem nthuav dav ntawm ntau qhov loj-caliber ncaj seam vuam tswj kav kav. Tus neeg kho tshuab txoj kab uas hla yog siv cov segmented kiv cua-shaped block ntawm qhov kawg ntawm txoj kab uas hla kom nthuav nws. Classified yas deformation ntawm tag nrho cov raj ntev.
1. Nws yog thawj zaug ncig. Lub kiv cua-shaped thaiv tau qhib kom txog thaum tag nrho cov kiv cua-shaped blocks nyob rau hauv kev sib cuag nrog lub puab phab ntsa ntawm cov yeeb nkab steel. Lub sijhawm no, lub vojvoog ntawm lub voj voog ntawm cov yeeb nkab steel yog yuav luag tib yam hauv cov kauj ruam loj, thiab cov yeeb nkab steel yog qhov ua ntej.
2. Lub npe sab hauv txoj kab uas hla theem. Ntxuam-shaped blocks pib los ntawm sab xub ntiag, kom txog rau thaum lawv mus txog qhov xav tau ntawm txoj haujlwm, uas yog Zhouxiang txoj haujlwm ntawm cov kev xav tau ntawm cov kev xav tau zoo.
3. Elastic rov qab them nyiaj rau theem. Nyob rau ntawm txoj hauj lwm ntawm theem thib ob, cov kiv cua-zoo li tus thaiv yuav raug txo kom txog rau thaum txoj hauj lwm yuav tsum tau, uas yog, txoj hauj lwm puag ncig ntawm lub elastic pem hauv ntej steel yeeb nkab yuav tsum tau los ntawm tus txheej txheem tsim.
