Rauv-welded yeeb nkab, tseem hu ua rauv pob tw-welded yeeb nkab, yog ib hom welded yeeb nkab uas yog tsim los siv cov txheej txheem vuam tshwj xeeb uas cuam tshuam nrog kev siv lub qhov cub. Txoj kev no feem ntau yog siv rau cov kav dej loj dua, feem ntau hauv kev tsim cov kav dej steel rau kev siv tshwj xeeb. Nov yog qee qhov tseem ceeb thiab cov yam ntxwv ntawm cov kav dej kub-welded:
Kev tsim khoom: Rauv-welded kav yog tsim los ntawm cua sov cov npoo ntawm steel daim hlau los yog strips nyob rau hauv lub cub tawg kom txog thaum lawv ncav cuag ib tug haum vuam kub. Thaum cov npoo yog txaus rhuab, lawv raug nias los yog dov ua ke los tsim ib tug nruam longitudinal seam weld.
Seam Quality: Lub cub tawg-welded seam feem ntau yog tus cwj pwm los ntawm nws qhov sib xws thiab sib xws. Kev tswj cua sov thiab siab nyob rau hauv lub cub tawg ua rau lub siab zoo seam tsim.
Khoom siv: Rauv-welded kav feem ntau yog tsim los ntawm carbon steel thiab low-alloy steel. Cov ntaub ntawv no feem ntau siv rau cov ntawv thov uas lub zog thiab kav ntev yog qhov tseem ceeb.
Loj Dia: Txoj kev vuam no tshwj xeeb yog tsim los tsim cov kav dej loj, xws li cov khoom siv hauv kev tsim cov kav dej rau kev thauj mus los ntawm cov roj, roj, thiab lwm yam dej.
Daim ntawv thov: Rauv-welded kav yog siv nyob rau hauv ntau yam hnyav-duty thiab tseem ceeb daim ntaub ntawv, nrog rau cov roj thiab roj pipelines, high-pressure fluid thauj, thiab structural kev siv nyob rau hauv kev tsim kho thiab infrastructure industries.
Kev Tswj Xyuas Zoo: Cov kav dej kub-welded undergo stringent zoo tswj kev ntsuas thiab soj ntsuam cov txheej txheem los xyuas kom meej qhov zoo ntawm cov vuam thiab tag nrho cov yeeb nkab. Kev kuaj tsis yog kev puas tsuaj (NDT) txoj hauv kev, xws li kev kuaj ultrasonic, yuav raug ua haujlwm los kuaj xyuas qhov tsis xws luag lossis qhov tsis sib xws.
Lub zog thiab Durability: Vim lub qhov cub-vuam txheej txheem, cov kav dej no paub txog lawv lub zog thiab kev ua haujlwm ntev, ua rau lawv tsim nyog rau cov ntawv thov uas lawv raug rau siab thiab hnyav.
Nqi-zoo: Rauv-welded kav feem ntau suav hais tias tus nqi-zoo rau daim ntaub ntawv loj-ntev vim lawv cov kev ua tau zoo hauv kev tsim cov welds muaj zog thiab txhim khu kev qha.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov kav dej kub-welded yog txawv los ntawm lwm cov yeeb nkab welded, xws li cov khoom siv hluav taws xob tiv thaiv vuam (ERW), Submerged Arc Vuam (SAW), lossis High-Frequency Induction Vuam (HFI). Kev xaiv ntawm txoj kev vuam yog nyob ntawm cov yam ntxwv xws li hom yeeb nkab, nws txoj kab uas hla, cov khoom siv, thiab cov phiaj xwm tshwj xeeb.
