Cov yeeb nkab steel ua los ntawm stitched vuam steel kav ua los ntawm kub-kuav los tiag steel daim hlau los yog steel band yob ntawm cov khoom siv vuam yog hu ua ncaj seam welded kav tau txais ntawm cov khoom siv vuam. Qhov ncaj seam welded steel yeeb nkab (YB242-63) yog cov yeeb nkab steel nrog lub longitudinal parallel ntawm cov vuam thiab cov yeeb nkab steel. 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 vuam ntawm txoj kab ncaj nraim tuaj yeem muab faib ua cov kav hlau ncaj nraim thiab faus arc welded ncaj seam steel kav. Ntawm lawv, tsis kam welded ncaj seam steel kav yog muab faib ua high-frequency vuam ncaj seam steel kav, nruab nrab-frequency vuam ncaj seam steel kav, tsawg-frequency vuam ncaj seam steel kav. Lub faus arc vuam ncaj seam steel yeeb nkab tseem hu ua ob-sided faus arc vuam ncaj seam steel yeeb nkab lossis LSAW ncaj seam steel yeeb nkab. LSAW yog (Longitudinally Submerged Arc Vuam abbreviation yog abbreviated li LSAW).
Electric Resistance Weldin, tseem hu ua ERW ncaj steel yeeb nkab, tseem hu ua Electric Resistance Weldin. High-frequency vuam ncaj seam steel yeeb nkab tseem hu ua ERW ncaj seam steel yeeb nkab. ERW yog ib lub npe sib sau ua ke rau cov kav dej resistor vuam. Electric resision welding (ERW) ERW yog thawj tsab ntawv sib raug rau cov lus Askiv, feem. Qhov kev tiv thaiv vuam steel yeeb nkab tau muab faib ua ob hom: AC welded steel yeeb nkab thiab DC welded steel yeeb nkab.
AC vuam yog muab faib ua tsawg zaus vuam, nruab nrab zaus vuam, ultra-nruab nrab-frequency vuam thiab high-frequency vuam raws li sib txawv frequencies. High-frequency welding yog tsuas yog siv rau kev tsim cov yeeb nkab nyias-walled steel los yog cov phab ntsa tuab tuab steel kav. High-frequency welding yog muab faib ua kev sib cuag vuam thiab inductive vuam. DC vuam feem ntau yog siv rau cov kav hlau me me.
Yog li ntawd, nyob rau hauv txhua rooj plaub, high-frequency welded kav muaj nyob rau hauv ERW welded kav. Nws yog ERW welded yeeb nkab uas tsim nyob rau hauv high-frequency vuam txheej txheem. ERW ncaj seam welded yeeb nkab yog cov yeeb nkab steel nrog cov khoom lag luam siab heev hauv kev lag luam roj thiab roj cia thiab kev thauj mus los. Qhov tshwm sim ntawm qhov tsis xws luag yog me me, thiab tuaj yeem thauj cov av noo acid natural gas nrog cov xwm txheej; tom qab lub cheeb yog nthuav dav, qhov geometric loj thiab qhov tseeb ntawm cov yeeb nkab steel yog siab; welding yog ua los ntawm txoj hauj lwm kab rov tav tom qab tsim tiav. Qhov ntev perimeter tswj tau zoo dua thiab qhov vuam zoo yog zoo heev.
