Dab tsi yog cov yam ntxwv tseem ceeb ntawm S235JR cov khoom?
S235JR yog ib qho qis -carbon non- alloy structural steel ua raws li EN 10025-2 tus qauv, nrog rau qhov tsawg kawg nkaus lub zog ntawm 235 MPa. Vim nws cov ntsiab lus tsis tshua muaj carbon, nws muaj qhov zoo heev weldability thiab formability; zoo cuam tshuam toughness ntawm chav tsev kub; thiab nruab nrab tensile zog.
Dab tsi yog qhov txawv ntawm txoj kev tsim ntawm S235JR longitudinally welded steel yeeb nkab thiab S235JR kauv welded steel yeeb nkab?
Qhov sib txawv tseem ceeb nyob hauv txoj kev tsim:S235JR longitudinally welded steel yeeb nkabyog tsim los ntawm dabtsi yog khoov steel sawb thiab welding ib tug ncaj weld raws qhov ntev ntawm cov yeeb nkab, thaumS235JR kauv welded steel yeeb nkabyog tsim los ntawm dov steel sawb ntawm lub helical lub kaum sab xis thiab welding raws ib tug kauv kab. Qhov no txhais tau hais tias yav dhau los siv lub vuam ncaj, thaum lub tom kawg siv cov kauv vuam.
Dab tsi yog txoj kev siv vuam ntau rau S235JR longitudinally welded steel kav?
Cov txheej txheem welding feem ntau rau cov kav hlau ntev ntev, suav nrog S235JR, suav nrog kev siv vuam tsis zoo (ERW) thiab cov kav ntev submerged arc vuam (LSAW). Cov arc vuam thev naus laus zis siv hauv cov yeeb nkab vuam muaj xws li phau ntawv arc vuam (SMAW), roj tiv thaiv hlau arc vuam (GMAW) (xws li MIG thiab MAG vuam), flux-cored hlau arc vuam (FCAW), submerged arc vuam, thiab tungsten inert gas welding (TIG).
Cov qauv zoo li cas feem ntau yog siv rau S235JR longitudinally welded steel kav?
S235JR longitudinally welded steel kavfeem ntau yog tsim raws li European tus qauv EN 10219, uas npog cov tshuab rau txias - tsim welded structural hollow profiles. Lwm cov qauv tsim muaj xws li EN 10210, Suav tus qauv GB / T1591, thiab Asmeskas tus qauv ASTM A53 / A106.
Dab tsi yog daim ntawv thov tseem ceeb ntawm S235JR longitudinally welded steel yeeb nkab?
S235JR longitudinally welded steel yeeb nkabyog tsim rau kev tsim loj - txoj kab uas hla, tuab -walled longitudinally welded steel kav. Nws yog feem ntau siv rau hauv siab - cov ntawv thov siab xws li cov kav dej roj thiab cov nkev. Vim nws lub zog muaj zog thiab ua haujlwm zoo, nws kuj tau siv dav hauv kev lag luam hluav taws xob, xws li cov chaw tsim hluav taws xob, kev tsim khoom, thiab kev tsim nkoj.
