Dab tsi yog cov txheej txheem tseem ceeb rau LSAW (Longitudinal Submerged Arc Welded) yeeb nkab?
Lub ntsiab txheej txheem rauLSAW tubyog txoj kev UOE (Ultra-Original Electrode) thiab JCOE (Joint Coiling) txoj kev. Ob qho txheej txheem koom nrog khoov cov ntawv hlau thiab tom qab ntawd welding nws longitudinal weld. Txoj kev UOE siv cais ua ntej-bending, U-forming, thiab O-forming presses, thaum JCOE txoj kev yog ib tug nruam stamping txheej txheem uas tsim cov hlau ntawv los ntawm ib tug series ntawm J-zoo li tus, C-zoo li tus, thiab O-zoo li tus txheej txheem.
