Kev ruaj ntseg vuam zoo yog qhov tseem ceeb tshaj plaws hauv lub taub qab vuam tshuab kom lav qhov kev ncaj ncees thiab kev ntseeg siab ntawm cov pob qij txha welded. Txoj kev tshawb nrhiav kom raug yog qhov tseem ceeb los txheeb xyuas qhov tsis xws luag thiab kev sib txawv uas tuaj yeem cuam tshuam kev ua haujlwm vuam. Kab lus no tshawb txog cov txheej txheem siv los txheeb xyuas qhov zoo ntawm cov vuam vuam hauv lub taub qab vuam tshuab, qhia txog lawv qhov tseem ceeb hauv kev tswj hwm cov qauv siab ntawm kev ncaj ncees.
- Kev Ntsuam Xyuas Kev Pom Zoo: Kev kuaj pom pom yog qhov yooj yim tshaj plaws thiab thawj txoj hauv kev txhawm rau txheeb xyuas qhov vuam zoo. Cov kws tshaj lij thiab cov kws tshuaj xyuas ua tib zoo tshuaj xyuas cov hlaws hlaws zoo li, nrhiav pom qhov tsis xws luag xws li cov kab nrib pleb, porosity, tsis tiav fusion, lossis qhov tsis sib xws ntawm cov hlaws profile.
- Kev Ntsuas Penetrant (PT): Kev ntsuam xyuas Penetrant yog ib qho kev sim tsis muaj kev puas tsuaj (NDT) uas suav nrog kev siv cov kua dej nkag mus rau qhov chaw vuam. Tom qab ib lub sij hawm nyob rau hauv ib tug tshwj xeeb lub sij hawm, ntau penetrant raug tshem tawm, thiab tus tsim tawm yog thov los kos tawm ib tug penetrant cuab nyob rau hauv defects. Txoj kev no tuaj yeem txheeb xyuas cov kab nrib pleb zoo thiab qhov tsis xws luag uas yuav tsis pom ntawm qhov muag liab qab.
- Sib Nqus Particle Testing (MT): Sib nqus particle kuaj yog lwm cov txheej txheem NDT siv los kuaj xyuas qhov chaw thiab qhov ze ntawm qhov chaw. Weld nto yog magnetized, thiab magnetic particle yog siv. Thaum muaj qhov tsis xws luag, cov khoom sib nqus sib sau ua ke thiab tsim cov cim qhia pom, tso cai rau cov neeg soj ntsuam xyuas qhov zoo ntawm qhov vuam.
- Ultrasonic Testing (UT): Ultrasonic kuaj yog ib txoj kev volumetric NDT uas siv cov suab nrov zaus los tshuaj xyuas welds. Ultrasonic nthwv dej raug xa mus rau hauv qhov vuam, thiab txhua yam kev puas tsuaj sab hauv lossis qhov tsis sib xws cuam tshuam cov nthwv dej rov qab mus rau tus txais. Txoj kev no yog qhov zoo tshaj plaws rau kev kuaj xyuas qhov tsis xws luag thiab ntsuas qhov vuam zoo.
- Radiographic Testing (RT): Kev ntsuam xyuas hluav taws xob cuam tshuam nrog kev hla X-rays lossis gamma rays los ntawm cov vuam thiab kaw cov hluav taws xob xa mus rau cov yeeb yaj kiab lossis cov cuab yeej digital. Txoj kev no tuaj yeem kuaj xyuas qhov tsis xws luag xws li voids, inclusions, thiab tsis muaj fusion, muab cov ncauj lus kom ntxaws txog cov weld tus qauv sab hauv.
- Kev Ntsuas Tensile: Kev ntsuas Tensile suav nrog kev xa cov qauv weld mus rau lub zog tensile tswj kom txog thaum nws tawg. Qhov kev ntsuam xyuas no yuav pab ntsuas lub vuam cov khoom siv kho tshuab, xws li qhov kawg tensile lub zog thiab elongation, thiab muab kev nkag siab rau hauv weld tag nrho lub zog thiab kev ua haujlwm.
- Khoov Test: Khoov kuaj yog siv los ntsuas qhov ductility thiab soundness ntawm welds. Ib ntu ntawm cov vuam yog khoov mus rau ib lub vojvoog tshwj xeeb kom pom tias muaj cov kab nrib pleb lossis qhov tsis xws luag tshwm rau ntawm sab nrauv. Qhov kev ntsuam xyuas no yog qhov tshwj xeeb tshaj yog rau kev kuaj xyuas qhov tsis xws luag hauv welds uas tej zaum yuav tsis pom tseeb los ntawm kev kuaj pom.
Hauv kev xaus, kev kuaj xyuas cov vuam zoo hauv lub pob tw vuam tshuab yog qhov tseem ceeb rau kev ua kom ntseeg tau thiab ua tau zoo welded pob qij txha. Kev soj ntsuam pom pom muab kev ntsuam xyuas thawj zaug, thaum muaj ntau yam kev sim tsis muaj kev puas tsuaj xws li PT, MT, UT, thiab RT muaj kev nkag siab ntau ntxiv rau qhov kev ncaj ncees. Kev ntsuas tensile thiab khoov kev sim muab cov ntaub ntawv tseem ceeb ntawm cov khoom siv hlau thiab cov khoom siv ductility. Los ntawm kev siv cov txheej txheem tshawb nrhiav no, cov neeg ua haujlwm vuam thiab cov neeg soj ntsuam tuaj yeem txhawb nqa cov qauv kev ua tau zoo, txheeb xyuas qhov tsis xws luag, thiab txiav txim siab paub daws teeb meem, kom ntseeg tau tias kev ua haujlwm vuam zoo ib yam thiab muaj kev vam meej hauv ntau daim ntawv thov.
