Dab tsi yog qhov sib txawv ntawm ER309L thiab ER309LSI?

Nyob rau hauv daim teb vuam, stainless hlau vuam hlau er er9l thiab er309lsi yog ob yam khoom uas tau nyiam ntau. Lawv saib zoo ib yam li, tab sis lawv muaj kev sib txawv me ntsis sib txawv hauv kev sib xyaw, kev ua tau zoo thiab daim ntawv thov. Cov sib txawv no yog qhov sib txawv yog qhov sib txawv yog qhov sib txawv ntawm cov kws ntsuam xyuas cov tshuab thiab cov kws kho mob, thiab cuam tshuam nrog kev ua tau zoo thiab ntau lawm.
Los ntawm cov kev pom ntawm cov tshuaj muaj pes tsawg leeg, cov ntsiab lus tseem ceeb ntawm EM3 {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} yog tsim nyog rau vuam ntawm ntau yam ntawm cov hlau stainless. Txawm li cas los xij, cov qhov sib txawv ntawm ob caug ntawm ob qho silicon (si) cov ntsiab lus. Silicon cov ntsiab lus ntawm ER309L yog 0. {{}}. 65%, Thaum cov Silicon cov ntsiab lus ntawm ER309LSi yog 0. {}}}%. Cov ntsiab lus ntau silicon tau dhau los ua qhov tseem ceeb hauv kev ua haujlwm tshwj xeeb ntawm er309lsi.
Qhov sib txawv hauv cov ntsiab lus silicon muaj qhov cuam tshuam tseem ceeb ntawm kev siv vuam ua tau zoo. Cov ntsiab lus ntau silicon cov ntsiab lus ntawm ER309LSI ua rau cov dej ua ke ua rau cov dej haus molten ntxiv thaum vuam. Cov yam ntxwv no yog tshwj xeeb yog nyob rau hauv roj av hlau arc vuam (GMAW), tseem hu ua MIG VUAM. Vim tias lub pas dej molten ntawm mig vuam yog tus siv da dej loj, pab muab cov khaub ncaws zoo nkauj thiab ua kom muaj kev sib tw vuam, thiab txo cov vuam ua kom zoo, thiab txo cov vuam kev ua tau zoo. Hauv kev sib piv, lub pas dej molten ntawm ER309L yog me ntsis qis dua, xws li tungsten inert roj vuam (Tig), nws tseem tuaj yeem tsim kho kev sib tw vuam kev ua tau zoo.
Hauv kev siv cov tswv yim, er309l thiab er309lsi feem ntau yog siv rau dissimilil hlau vuam, xws li cov hlau stainless hlau, thiab qee cov hlau steel, thiab qee cov hlau steel, thiab qee qhov steel hlau vuam uas yuav tsum corrosion tsis kam. Txawm li cas los xij, ER309LSi muaj qhov zoo hauv cov xwm txheej uas tau siv cov khoom siv vuam thiab cov hlau loj uas muaj cov hlau loj ER309L, ntawm qhov tod tes, ua tau zoo nyob rau qee qhov chaw vuam zoo nrog kev tsim kho me me, uas tau them ntau dua rau kev zoo nkauj me me thiab zoo kawg ntawm Weld.
Although ER309L and ER309LSI are similar in many aspects, their differences in silicon content, welding performance and application scenarios provide welding engineers with diverse choices under different work requirements. Thaum xaiv cov hlau vuam, cov neeg yuav tsum tau txiav txim siab ntau yam xws li kev txiav txim siab zoo tshaj plaws los ua kom muaj kev txiav txim siab zoo tshaj plaws rau kev ua kom tiav vuam ua haujlwm.
Qhia cov ncauj lus kom ntxaws ntawm daim ntawv thov ntawm er309l thiab Er309LSi hauv ntau hom lag luam hlau tsim nyog rau kev siv vuam hlau tsim nyog rau kev siv hlau vuam ua haujlwm? Dhau li Er309L thiab Er309LSi, dab tsi lwm cov xov hlau vuam vuam hlau muaj cov khoom zoo sib xws?
