Dab tsi yog industrial NDT & XRAY

Industrial NDT (Non-Destructive Testing)
Industrial NDT yog hais txog cov txheej txheem kev siv hauv kev lag luam txhawm rau txheeb xyuas, ntsuas, thiab tshuaj xyuas qhov tsis xws luag sab hauv lossis saum npoo, cov khoom siv, lossis cov qauv kev ncaj ncees ntawm cov khoom lossis cov khoom tsis muaj kev puas tsuaj rau cov khoom kuaj. Nws yog dav siv nyob rau hauv kev tsim, aerospace, lub zog, metallurgy, kev tsim kho, thiab lwm yam lag luam los xyuas kom meej cov khoom zoo, tiv thaiv kev raug mob, thiab txo cov nqi.

Common Industrial NDT Methods:

1. Kev kuaj ultrasonic (UT)
   • Siv lub suab nrov nrov los tshawb xyuas cov teeb meem sab hauv (xws li, tawg, voids) los ntawm kev txheeb xyuas cov teeb liab pom.
   • Haum rau cov khoom tuab thiab cov khoom siv hlau.
2. Kev ntsuas hluav taws xob (RT)
   • Xws li kev kuaj X-ray thiab gamma-ray. Siv hluav taws xob hluav taws xob hluav taws xob (X-rays) txhawm rau nkag mus rau cov ntaub ntawv thiab tsim cov duab ntawm cov qauv sab hauv ntawm zaj duab xis lossis digital sensors.
   • Siv tau rau kev kuaj xyuas qhov tsis xws luag xws li tawg, suav nrog, thiab vuam flaws.
3. Sib Nqus Particle Test (MT)
   • Siv cov hlau nplaum sib nqus rau cov khoom siv ferromagnetic. Nto lossis ze-nto qhov tsis xws luag raug nthuav tawm los ntawm cov khoom sib nqus sib txuas ntawm qhov chaw tsis zoo.
   • Feem ntau siv rau kev tshuaj xyuas cov khoom steel.
4. Kev Ntsuas Penetrant (PT)
   • Koom nrog kev siv cov kua dej nkag mus rau qhov chaw. Defects nqus cov penetrant, uas yog ces visualized siv tus tsim tawm los qhia qhov chaw-tawg flaws.
   • Haum rau cov ntaub ntawv tsis ntxeem tau xws li hlau thiab yas.
5. Eddy Current Testing (ET)
   • Siv electromagnetic induction los xyuas qhov chaw los yog subsurface defects nyob rau hauv cov ntaub ntawv conductive. Cov kev hloov pauv hauv cov qauv tam sim no qhia txog qhov tsis zoo.
   • Dav siv nyob rau hauv aerospace thiab automotive industries.

X-Ray hauv Industrial NDT

Cov ntsiab cai:

• X-rays nkag mus rau cov khoom kuaj, thiab lawv qhov kev siv zog txo qis raws li cov khoom siv qhov ntom thiab tuab.
• Cov teeb meem (piv txwv li, voids, kab nrib pleb, los yog cov khoom txawv teb chaws) tshwm sim raws li cov duab ntxoov ntxoo ntawm qhov nruab nrab imaging (zaj duab xis los yog digital detector) vim muaj qhov sib txawv ntawm qhov nqus.

Daim ntawv thov:

1. Kev tshuaj xyuas Weld
   • Tshawb nrhiav tsis tiav fusion, porosity, los yog slag inclusions hauv welds.
2. Aerospace Components
   • Tshawb xyuas turbine hniav, cav qhov chaw, thiab cov ntaub ntawv sib xyaw kom pom qhov tsis xws luag.
3. Manufacturing Quality Control
   • Xyuas kom casting lossis forging kev ncaj ncees los ntawm kev txheeb xyuas qhov tsis zoo ntawm sab hauv.
4. Pipeline thiab Pressure Vessel Inspection
   • Kev ntsuam xyuas cov qauv kev ncaj ncees ntawm cov kav dej thiab cov tso tsheb hlau luam yam tsis muaj disassembly.

Qhov zoo:

• Muab cov ntaub ntawv pom kev mus tas li (radiographs) rau cov ntaub ntawv thiab rov ua dua tshiab.
• Haum rau cov ntaub ntawv tuab thiab nyuaj geometry.
• Nws tuaj yeem kuaj pom ob qho tib si saum npoo thiab sab hauv.

Kev txwv:

• Yuav tsum tau ceev faj txog kev nyab xeeb (xws li, tiv thaiv hluav taws xob) vim muaj kev phom sij rau kev noj qab haus huv los ntawm kev raug mob ntev.
• Tsis tshua muaj txiaj ntsig rau cov khoom siv tsawg (piv txwv li, plastics) tshwj tsis yog siv cov txheej txheem tshwj xeeb.
• Cov cuab yeej siv siab dua thiab cov nqi ua haujlwm piv rau lwm txoj hauv kev NDT.
