ERW steel yeeb nkab yog dab tsi?
Resistance welded (ERW) steel yeeb nkabyog cov yeeb nkab steel khoom tsim longitudinally siv cov cuab yeej siv vuam vuam. Kev tiv thaiv vuam cuam tshuam nrog txias- ua kub- dov steel coils rau hauv cov kav hlau los ntawm ntau cov chais, thiab tom qab ntawd vuam / fusion los ntawm kev siv hluav taws xob tam sim no.
Cov txheej txheem ua haujlwm zoo li cas rau S235JRH cov qauv ERW steel yeeb nkab?
Cov txheej txheem tsim nyog rauS235JRH qauv ERW steel yeeb nkabsuav nrog vuam thiab txias sib sau. Vim nws cov ntsiab lus carbon tsawg, cov yeeb nkab steel no zoo tagnrho rau vuam siv cov qauv vuam electrodes yam tsis muaj preheating.
Lub tsev tsim dab tsi yog S235JRH structural ERW steel yeeb nkab feem ntau siv hauv?
S235JRH qauv ERW steel yeeb nkabFeem ntau yog siv nyob rau hauv cov txheej txheem thav duab ntawm cov tsev, xws li kab teeb thiab kab, bracing systems, thiab tag nrho cov txheej txheem ntawm kev lag luam, vaj tse, thiab industrial vaj tse.
Qhov zoo ntawm S235JRH cov qauv ERW steel yeeb nkab raug tshuaj xyuas li cas?
Kev soj ntsuam zoo ntawmS235JRH qauv ERW steel kavntiav cov txheej txheem ntau- theem, suav nrog tsis yog- kuaj kev puas tsuaj (NDT), cov cuab yeej cuab tam thiab tshuaj lom neeg kuaj, thiab kuaj pom qhov kawg thiab qhov ntev. Cov khoom kuaj tseem ceeb suav nrog kev kuaj ultrasonic ntawm welds, kuaj tensile, kuaj qhov cuam tshuam, thiab tshuaj xyuas cov tshuaj muaj pes tsawg leeg.
Dab tsi yog qhov txawv ntawm S235JRH structural ERW steel kav thiab kauv welded kav?
S235JRH qauv ERW steel kavyog dov los ntawm ca steel strips rau hauv cov kav dej, thiab tom qab ntawd welded longitudinally siv ib qho siab - zaus kuj weld los tsim ib tug du thiab zoo ib yam sab hauv. Nyob rau hauv sib piv, kauv welded kav yog tsim los ntawm dov steel strips mus rau hauv ib tug nruam kauv weld ntawm ib tug helical lub kaum sab xis ua ntej welding.
