Nrog rau txoj kev loj hlob sai ntawm high-quality steel dov ntau lawm thiab kev nce qib ntawm vuam thiab tshuaj xyuas tshuab, qhov zoo ntawm welds tau raug txhim kho tas li, thiab ntau yam welded kav kuj tau nce, thiab seamless steel kav tau hloov ntau thiab ntau dua. thaj chaw. Nyob rau hauv cov txheej txheem ntawm cov yeeb nkab welded, qhov siab ntawm vuam seam tuaj yeem piav qhia raws li qhov tseem ceeb heev. Muaj ntau yam teeb meem uas cov vuam seams ntawm cov yeeb nkab welded loj heev. raws li nram no:
Kev ntxhov siab corrosion tawg yog yooj yim tsim ntawm cov ntiv taw vuam
Qhov kev ntxhov siab ntawm cov pob qij txha docking feem ntau yog tshwm sim los ntawm qhov siab ntawm qhov vuam. Cov welded pob qij txha ntawm lub connector yog qhov kev nyuaj siab tshaj plaws ntawm lawv cov ntiv taw welded.
Qhov loj ntawm qhov kev ntxhov siab coefficient nyob ntawm qhov siab ntawm vuam seam residue, lub kaum sab xis θ ntawm vuam ntiv taw, thiab lub kaum sab xis R. Qhov siab ntawm vuam seams nce, thiab lub kaum sab xis θ nce, thiab R tus nqi txo. , uas yuav ua rau kom cov concentration coefficient ntawm kev ntxhov siab.
Qhov siab dua qhov siab ntawm qhov vuam, qhov hnyav dua qhov concentration ntawm kev ntxhov siab, thiab kev siv ntawm cov vuam sib txuas yuav raug txo. Tom qab vuam, qhov seem qhov siab yog flattened. Tsuav nws tsis qis dua cov khoom siv niam, txo qis kev ntxhov siab, qee zaum nws tuaj yeem ua rau muaj kev sib koom ua ke ntawm kev sib koom ua ke.
Qhov seem welding seam tseem siab, uas cuam tshuam rau lub raj zoo tom qab lub cheeb ntawm cov dej siab
Thaum qhov ncaj seam faus arc welded yeeb nkab tau nthuav dav hauv cov dej siab, cov yeeb nkab steel yog qhwv los ntawm sab laug thiab sab xis ntawm cov kab noj hniav thiab cov cim ntawm cov yeeb nkab steel. Yog li ntawd, qhov seem ntawm qhov siab ntawm cov weld loj dhau lawm, thiab cov kev ntxhov siab shear raug kev txom nyem los ntawm cov welded seam thaum lub sij hawm txoj kab uas hla yog loj, thiab qhov tshwm sim "me me ncaj" yog nquag tshwm sim ntawm ob sab ntawm lub vuam.
Txawm li cas los xij, kev paub dhau los ua pov thawj tias thaum qhov siab ntawm sab nraud yog tswj hwm ntawm 2 hli, qhov tshwm sim "sab me me" yuav tsis tshwm sim thaum lub qhov siab ntawm lub taub yog nthuav dav, thiab lub raj zoo yuav tsis cuam tshuam. Qhov no yog vim qhov seem ntawm qhov siab ntawm sab nraud yog me me, thiab qhov kev nyuab siab shear kuj me me nyob rau hauv qhov sib koom ua ke. Tsuav qhov kev ntxhov siab no nyob rau hauv qhov elastic deformation ntau yam, tom qab uninstalling, lub raj yuav rov qab los.
Qhov seem welding seam yog siab, uas yog tsis conducive rau anticorrosive
Yog tias koj siv epoxy resin iav daim ntaub los tiv thaiv corrosion, qhov seem vuam seams yog siab, uas yuav ua rau nws nyuaj rau vuam ntiv taw. Nyob rau tib lub sijhawm, qhov siab dua qhov vuam seam, lub thicker lub anti-corrosion txheej yuav tsum thicker. Vim hais tias lub thickness ntawm anti-corrosion txheej yog xam nyob rau hauv lub benchmark ntawm lub thickens ntawm anticorrosive txheej, qhov no nce tus nqi ntawm anticorrosion.
Thaum cov kauv faus arc vuam, sab nraud vuam seam ntawm "ntses ridge" yog feem ntau ua rau, uas yog qhov nyuaj dua los xyuas kom meej qhov zoo ntawm anticorrosion. Yog li ntawd, nws tseem yog ib qho tseem ceeb uas yuav tau kho lub spatial txoj hauj lwm thiab vuam specification ntawm lub vuam taub hau kom txo los yog tshem tawm cov txheej vuam seam ntawm "ntses ridge".
