SAW steel yeeb nkab yog muab faib ua longitudinally welded submerged arc welded ncaj seam steel yeeb nkab L-SAW thiab kauv welded submerged arc welded kauv steel yeeb H-SAW. L-SAW steel yeeb nkab muaj UO txoj kev tsim tsim rau kev tsim khoom loj, txoj kev khoov yob thiab cov xovxwm tshuab txoj kev tsim nyog rau ntau hom.
JCOE molding txoj kev yog ib txoj kev ntawm UO molding txoj kev thiab xovxwm tshuab txoj kev. Txawm hais tias muaj cov txheej txheem nthuav dav ntawm qhov kawg ntawm lub siab muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm cov yeeb nkab steel, thiab seb cov txheej txheem tam sim no tseem yog ib qho ntawm cov kev faib tawm.
H-SAW yog sib npaug rau kauv welded yeeb nkab, uas yog tsim los ntawm kev tsim ib co coiled steel phaj rau hauv ib tug kauv zoo, thiab ces welding lub pob tw. Ntxiv rau cov txheej txheem ntawm kev tsim thiab tack vuam ua raws li SAW, txhawm rau kom tau txais cov khoom tsim tau zoo thiab cov kav hlau zoo, ob-kauj ruam welding ntawm SAW hauv lwm cov kab ntau lawm tom qab tack welding kuj siv tau.
