Cov ntaub ntawv dab tsi yog siv los ua S355J2H structural welded yeeb nkab?
S355J2H qauv welded yeeb nkabyog ua los ntawm cov hlau tsis yog- alloy zoo- cov hlau. Cov khoom no yog tsim tshwj xeeb rau kev siv cov qauv thiab paub txog nws lub zog siab, weldability zoo heev, thiab qis - kub toughness.
Dab tsi yog cov txheej txheem vuam tseem ceeb siv rau S355J2H cov qauv welded yeeb nkab?
Lub ntsiab vuam txheej txheem rauS355J2H qauv welded yeeb nkabyog cov welding tsis kam (ERW) thiab submerged arc vuam (SAW). Txoj kev tshwj xeeb feem ntau yog nyob ntawm qhov xav tau ntawm cov yeeb nkab loj thiab phab ntsa thickness.
Lub vuam zoo ntawm S355J2H cov txheej txheem welded yeeb nkab yog li cas?
Qhov vuam zoo ntawmS355J2H steel yeeb nkabyog ua kom ntseeg tau los ntawm kev sib xyaw ua ke ntawm cov txheej txheem tswj, preheating, cov txheej txheem vuam kom raug, thiab kev tshuaj xyuas zoo. Qhov no suav nrog kev siv cov ntaub ntawv muab tub lim tsim nyog, tswj xyuas cov vuam tsis zoo (xws li qhov kub thiab qhov ceev), thiab ua tsis tau -kev kuaj kev puas tsuaj thiab kev puas tsuaj ntawm cov khoom tiav, xws li kev kuaj ultrasonic, X- kev ntsuas hluav taws xob, thiab kev ntsuas cov khoom siv tshuab.
Dab tsi yog qee qhov kev siv tsis yog -kev kuaj kev puas tsuaj rau S355J2H structural welded steel yeeb nkab?
Feem ntau siv tsis yog -kev kuaj kev puas tsuaj (NDT) txoj hauv kev rauS355J2H steel kavsuav nrog: kuaj ultrasonic (UT); Magnetic particle kuaj (MT); eddy tam sim no kuaj (ECT); Kev kuaj hluav taws xob (RT); thiab kev tshuaj xyuas qhov muag.
Dab tsi yog qhov tseem ceeb los tiv thaiv - txoj kev kho corrosion rau S355J2H structural welded steel kav?
Lub ntsiab tiv thaiv- txoj kev kho corrosion rauS355J2H structural welded steel kavsuav nrog cov txheej txheem saum npoo, xws li kub-dip galvanizing, 3PE txheej, thiab ntau yam xim / epoxy resin txheej, nrog rau zinc txau thiab tiv thaiv varnishing.
