Seamless welding yog siv thaum seamless steel kav yog welded, vim seamless vuam yog ntau nyob rau hauv txoj kab nrog cov khoom yam ntxwv. Tab sis seamless vuam tsis yog yooj yim, vim hais tias nws yuav tsum tau ntau kauj ruam, peb yuav tsum txhim kho ib kauj ruam yog kauj ruam, thiab thaum welding, peb kuj yuav tsum mastering lub tshav kub, siab heev los yog tsawg heev tsis haum rau welding. Vim hais tias yog lub tshav kub mastered, ces qhov zoo ntawm peb cov khoom yog kuj txhim khu kev qha.
Seamless steel kav muab faib ua UOE txoj kev tsim, RBE JCOE steel yeeb nkab, thiab lwm yam raws li ntau hom. Qhov no yog qhov feem ntau high-frequency submerged arc vuam txoj kev. Kev tsom xam thiab kev kawm txog cov txheej txheem vuam, muaj peev xwm radiography, cov duab paub txog cov kev tsis sib haum xeeb thiab lwm yam kev tsis xws luag raws li cov yeeb nkab sib koom ua ke ua rau kev ntsuam xyuas qhov tseeb ntawm qhov tsis tiav fusion. Rau qee qhov me me, cov hlau welded nyob rau saum npoo thaum vuam yog qhov loj ntawm convex curvature, tsab xov xwm no tsis haum rau kev ceev ntawm kev thauj mus los vuam, nws yog ib qho nyuaj rau tshwm sim vim qhov ceev vuam txheej ntawm lub raj ntawm fusion ntawm tsis xws luag thiab duab ua haujlwm.
Thaum lub seamless steel yeeb nkab tau nthuav dav los ntawm cov dej siab, cov yeeb nkab steel yog qhwv los ntawm cov pwm sab nraud ntawm sab laug thiab sab xis ntawm cov kab noj hniav uas zoo ib yam nrog qhov nthuav dav ntawm cov yeeb nkab steel, yog li ntawd, qhov seem ntawm qhov siab ntawm qhov vuam. yog loj heev, thiab shear kev nyuaj siab ntawm lub weld yog loj thaum txoj kab uas hla yog nthuav, thiab "me me ncaj ntug" phenomenon yog ib qho yooj yim mus tshwm rau ntawm ob sab ntawm lub weld. Txoj kev loj hlob ntawm cov vaj tse pob zeb tau txhawb nqa kev tsim kho tshiab ntawm cov hlau siv, uas tau pom nyob rau hauv qhov kev vam meej tshiab ntawm ntau hom steel tuav siv hauv cov pob zeb ua vaj tse thiab cov pob zeb prestressed.
