Yuav ua li cas cov shielding gas xav tau rau MIG welding stainless hlau?
Rau stainless hlau MIG vuam, xaiv txoj cai shielding gas yog ib qho tseem ceeb heev kom ua tau ib tug zoo weld. Qhov tseeb shielding roj tsis tsuas yog tiv thaiv cov weld los ntawm atmospheric paug, tab sis kuj cuam tshuam rau weld nkag mus, weld hlaws zoo li thiab tag nrho vuam zoo.
Stainless hlau cov neeg muag khoom feem ntau pom zoo kom siv cov tshuaj tiv thaiv roj sib xyaw uas muaj feem pua ntawm argon, feem ntau nyob ib ncig ntawm 98%. Qhov no yog vim argon yog ib qho roj inert uas pab tiv thaiv oxidation thaum lub sij hawm vuam, uas tuaj yeem ua rau cov vuam tsis zoo thiab tawg.
Lwm cov roj siv rau MIG vuam stainless hlau yog helium-argon sib tov. Cov roj no tau zoo dua permeability thiab cov hlaws zoo, tab sis yog kim dua li cov ntshiab argon.
Welders kuj tuaj yeem siv cov roj sib xyaw ua ke, uas yog kev sib xyaw ntawm argon, helium thiab carbon dioxide. Cov roj sib tov no feem ntau yog siv rau vuam tuab stainless hlau thiab muab kev nkag tau zoo heev thiab weld hlaws zoo.
Thaum xaiv cov roj tiv thaiv rau MIG welding stainless hlau, qib ntawm stainless hlau raug welded, qhov yuav tsum tau weld zoo thiab qhov chaw vuam yuav tsum tau txiav txim siab. Qee cov qib stainless hlau, xws li 316, yuav tsum muaj ntau dua ntawm argon hauv cov roj tiv thaiv kom ua tiav cov vuam zoo.
Nws tseem yog ib qho tseem ceeb uas yuav tau txiav txim siab txog hom hlau siv rau MIG vuam stainless hlau vim qhov no yuav cuam tshuam rau kev xaiv cov roj thaiv kev tiv thaiv. Piv txwv li, flux-cored hlau yuav xav tau ib qho sib txawv shielding gas sib tov dua li cov khoom siv hlau.
Hauv cov ntsiab lus, cov khoom siv stainless hlau feem ntau pom zoo kom siv cov roj sib xyaw tiv thaiv uas muaj feem pua ntawm argon rau MIG vuam stainless hlau. Txawm li cas los xij, qhov tshwj xeeb tiv thaiv kev xaiv roj yuav nyob ntawm qib ntawm cov hlau tsis huv uas tau welded, qhov zoo ntawm cov vuam xav tau, thiab hom hlau siv. Welders yuav tsum ua tib zoo xaiv cov khoom siv tiv thaiv kom ua tiav qhov zoo tshaj plaws weld zoo thiab tiv thaiv kev sib kis thaum lub sijhawm vuam.
