Welded yeeb nkabfeem ntau muab faib ua ncaj seam welded yeeb nkab thiab kauv welded yeeb nkab ob hom.

Vuam txheej txheem

Los ntawm cov txheej txheem welding, Vuam txoj kev ntawm cov kauv welded yeeb nkab thiab ncaj seam steel yeeb nkab yog zoo ib yam, tab sis ncaj seam welded yeeb nkab yuav inevitably muaj ntau t-shaped weld, yog li qhov tshwm sim ntawm weld defects kuj zoo heev, thiab cov t-shaped seam welding residual kev nyuaj siab yog loj dua, lub xeev kev nyuaj siab ntawm cov hlau weld feem ntau nyob rau hauv peb txoj kev tsub kom muaj ib tug tawg.Thiab, raws li cov kev cai ntawm submerged arc vuam txheej txheem, txhua weld yuav tsum muaj arc thiab arc. nyob rau hauv, tab sis txhua tus ncaj seam welded yeeb nkab thaum weld girth, tsis tuaj yeem ua tau raws li cov xwm txheej, yog li yuav muaj ntau dua ntawm arc vuam tsis xws luag.

Cov yam ntxwv muaj zog

Thaum lub siab nyob rau hauv cov yeeb nkab tiv taus, feem ntau yog ob lub ntsiab kev nyuaj siab ntawm phab ntsa, uas lub radial thiab axial stress stressδ.Synthetic weld stressδ, qhov twgα yog lub helix lub kaum sab xis ntawm cov kauv vuam yeeb nkab.Kauv welded seam degree helix lub kaum sab xis feem ntau yog li hluavtaws, thiab kauv weld Longitudinal kev nyuaj siab yog lub ntsiab kev ntxhov siab.Nyob rau hauv tib lub zog ua haujlwm, kauv yeeb nkab ntawm tib txoj kab uas hla tshaj qhov Longitudinal phab ntsa thickness yuav raug txo.

Hydrostatic tawg zog

Los ntawm qhov kev sib piv cov kev ntsuam xyuas kom paub tseeb cov kauv welded yeeb nkab thiab Longitudinal yield siab thiab tawg siab ntsuas thiab theoretical qhov tseem ceebuamatch, qhov sib txawv los ze zog.Tab sis txawm hais tias nws yog qhov kev ntxhov siab los yog tawg siab, tau qis dua qhov Longitudinal kauv welded.Kev ntsuam xyuas tawg kuj qhia tau hais tias tus nqi ntawm deformation nplhaib kauv welded yeeb nkab bursting Longitudinal ho ntau dua lub qhov ncauj.Yog li paub tseeb tias cov kauv welded yas deformation muaj peev xwm tshaj Longitudinal, blasting lub qhov ncauj feem ntau nyob rau hauv ib lub suab, uas yog lub extension ntawm kauv weld rau rip los ntawm ib tug muaj zog binding nyhuv vim.

Toughness thiab qaug zog

Qhov sib txawv ntawm txoj kev loj hlob ntawm cov kav dej yog ntawm txoj kab uas hla loj thiab siab zog.Nrog rau qhov nce ntawm txoj kab uas hla ntawm cov yeeb nkab thiab cov qib steel nce, qhov ntau dua ntawm cov ductile pob txha taub hau khov kho nthuav dav.Txawm hais tias kauv welded yeeb nkab thiab ncaj seam welded yeeb nkab muaj tib theem, kauv welded yeeb nkab yog nrog rau siab heev toughness.Kev xa cov kav dej vim qhov hloov pauv ntawm qhov kev ua haujlwm tiag tiag, cov yeeb nkab yuav raug random alternating load effect.
