Xav txog, ib pliag, cov ntawv thov tseem ceeb uas xav tau qhov kub qis heev. Cov kws tshawb fawb ua tib zoo saib xyuas cov hlwb, uas yuav cawm tau neeg txoj sia. Cov foob pob hluav taws tua mus rau hauv qhov chaw, tsav los ntawm cov roj txias dua li cov uas pom muaj nyob hauv ntiaj teb. Cov nkoj loj thauj cov roj av liquefied thoob plaws ntiaj teb. Dab tsi yog lub hauv paus ntawm cov haujlwm no? Kev tsim kho tshiab ntawm kev tshawb fawb ua lub luag haujlwm, tab sis kuj tseem ceeb heevCov Kav Dej Nqus Tsev(VIPs) thiab cov neeg txawj uas vuam lawv.

Qhov degree ntawm engineering uas xav tau rau kev siv cov khoom cryogenic kom muaj kev nyab xeeb yog qhov tsis tshua muaj neeg pom.Cov Kav Dej Nqus Tsevsawv cev rau kev sib xyaw ua ke ntawm cov thev naus laus zis tshiab thiab kev txawj ntse ntawm tib neeg. Cov kav dej no yuav tsum tuav tau qhov kub thiab txias heev, tiv taus lub zog nqus tsev, thiab txawm tias muaj cov kua dej uas muaj peev xwm ua rau muaj kev phom sij. Peb yuav tsum xav txog tias txawm tias qhov tsis zoo me me, xws li qhov xau me ntsis lossis qhov tsis zoo me me ntawm kev rwb thaiv tsev, tuaj yeem ua rau muaj teeb meem loj.

Yuav tsum ua li cas thiaj li ua tau qhov kev vuam no kom raug? Muaj ob peb txoj kev vuam raws li nram no:

1. Kev Siv Gas Tungsten Arc Vuam (GTAW): Xav txog ib tug kws ua moos sib dhos ib lub moos uas nyuaj heev lossis ib tug kws phais neeg ua ib qho kev phais mob uas nyuaj heev. Txawm hais tias cov tshuab muab kev taw qhia, qhov kev txawj ntse ntawm tus kws vuam tseem ceeb heev. Lawv lub qhov muag ntse thiab tes ruaj khov ua kom cov pob qij txha zoo ntawm cov yeeb nkab sab hauv, uas yog qhov tseem ceeb rau kev thauj cov kua dej cryogenic kom muaj kev nyab xeeb.

2. Kev Siv Gas Metal Arc Vuam (GMAW): Thaum GTAW muab qhov tseeb tso ua ntej, Kev Siv Gas Metal Arc Vuam (GMAW) ua tiav qhov sib npaug ntawm qhov ceev thiab kev ua haujlwm zoo. Hauv hom pulsed, GMAW zoo rau kev tsim lub tsho sab nraud ntawm aCov Yeeb Nkab Nqus Tsev, muab kev tiv thaiv thaum tswj hwm qhov project kom ua tiav.

3. Kev Vuam Siv Laser Beam (LBW): Qee zaum, yuav tsum muaj kev vuam kom raug dua li kev vuam ib txwm muaj. Hauv cov xwm txheej zoo li no, cov neeg vuam siv Laser Beam Vuam (LBW). Txoj kev no siv lub zog fais fab los tsim cov vuam nqaim nrog kev tsim cua sov tsawg.

Muaj cov khoom siv zoo yog qhov tseem ceeb, tab sis nws tsis yog tib kauj ruam xwb. Cov neeg vuam uas ua tau zoo yuav tsum paub txog kev tshawb fawb txog cov ntaub ntawv, kev ua haujlwm ntawm cov roj tiv thaiv, thiab kev tswj cov txheej txheem vuam. Yog li, kev cob qhia thiab daim ntawv pov thawj lees paub yog qhov tseem ceeb kom ntseeg tau tias lub kaw lus muaj kev nyab xeeb thaum siv cov thev naus laus zis cryogenic.

Cov tuam txhab zoo liHL Cryogenicnqis peev rau cov neeg ua haujlwm mob siab rau kom ntseeg tau tias yav tom ntej zoo dua rau txhua tus. Los ntawm kev ua tej yam zoo li ntawd, peb tuaj yeem pab tsim kom muaj ib puag ncig nyab xeeb rau cov tiam neeg tom ntej kom xav tsis thoob txog cov thev naus laus zis no.
