Vuam thiab Fabrication Kev Coj Ua
Q1: Dab tsi cov txheej txheem vuam yog cov feem ntau haum rau A53B yeeb nkab?
A1: Cov txheej txheem tsim nyog suav nrog cov ntaub thaiv hlau arc vuam (smaw) rau cov vuam (gtaw) rau cov vuam (GMAW) rau cov khoom lag luam hauv khw. Flux - cored arc vuam (FCAW Kev xaiv yog nyob ntawm txoj haujlwm, tuab, yuav tsum tau ua kom zoo, thiab muaj cov cuab yeej tsim nyog ua kom tau txais kev thov kom tsim nyog rau txhua rooj plaub tshwj xeeb.
Q2: Yuav ua li cas preheat thiaj li txiav txim siab thiab thov rau A53B vuam?
A2: preheat kub kev txiav txim siab txiav txim siab cov ntaub ntawv tuab, cov roj carbon sib npaug, thiab cov xwm txheej ambient. Cov ntau npaum li cas yog 50 {4 {{}} xyoo 200℃raws li cov lus, thov sib xyaw ua ke nyob ib ncig ntawm kev sib ncig. Kev ntsuas siv qhov kub thiab txias-}} Qhia tau hais tias muaj cov xaum xim lossis hu rau pyrometers, tswj cov vuam li cuam tshuam. Tsim nyog ua kom muaj kev kub ntxhov, tiv thaiv hydrogen {{}}}}}} patructure txaus nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam.
Q3:: Dab tsi kev kuaj xyuas ua raws A53B vuam ua tiav?
A3: Post {{{{- Weld tshuaj xyuas rau kev kuaj pom saum npoo av, thiab tsis muaj kev cuam tshuam rau ib qho kev cai tshwj xeeb. Siab sim tshaj tawm kom nruj, thaum cov ntaub ntawv muab cov ntaub ntawv zoo. Txhua txoj kev kho vaj tse uas tau rov ua dua tshiab, kom ua raws li cov qauv kev siv tau thiab cov kev qhia tshwj xeeb.
Q4: Yuav ua li cas distortion thiab residual kev nyuaj siab tswj hauv 53b fabrication?
A4: Cov tswv yim tswj kev tswjfwm suav nrog kev ntsuas vuam sib txuas tsis tau lees paub cua sov, prese qhov ntev, thiab kev sib tsoo ib ntus kom muaj kev sib tsoo thaum vuam. Peening yuav pab txo cov kev ntxhov siab hauv qee cov ntawv thov, thaum kev kho cua sov kawg ua kom pom kev ruaj khov thiab kev daws teeb meem kev ntxhov siab.
Q5: Yuav ua li cas kev ua kev nyab xeeb yog qhov tseem ceeb thaum A53B vuam?
A5: Cov kev coj ua tseem ceeb suav nrog kev nqus tau zoo fume thiab cov khoom tiv thaiv tus kheej tawm tsam kev ntsuas kev tiv thaiv kev ua haujlwm tsis zoo. Kev tiv thaiv hluav taws kub yuav tsum tau tshem tawm cov kev sib txuas lus thiab muaj kev tshem tawm cov txheej txheem kev tiv thaiv thaj chaw tiv thaiv cov neeg ua haujlwm. Cov kev ntsuas no ua kom muaj kev ua haujlwm kom nyab xeeb thaum lub sijhawm ua haujlwm.
