Kev puas tsuaj nrhiav pom txheej txheem

1. NDT yog hais txog ib qho kev sim rau cov khoom siv lossis cov khoom ua haujlwm uas tsis ua kom puas lossis cuam tshuam rau lawv qhov kev ua tau zoo lossis kev siv yav tom ntej.

2. NDT tuaj yeem pom qhov tsis xws luag hauv sab hauv thiab saum npoo ntawm cov ntaub ntawv lossis cov khoom ua haujlwm, ntsuas cov yam ntxwv geometric thiab qhov ntev ntawm cov khoom ua haujlwm, thiab txiav txim siab cov khoom siv sab hauv, qauv, lub cev thiab lub xeev ntawm cov khoom lossis cov khoom ua haujlwm.

3. NDT tuaj yeem siv rau kev tsim khoom, xaiv cov khoom siv, kev tsim khoom thiab kev tsim khoom, kev tshuaj xyuas cov khoom tiav, kev tshuaj xyuas hauv kev pabcuam (kev saib xyuas), thiab lwm yam, thiab tuaj yeem ua lub luag haujlwm zoo ntawm kev tswj xyuas thiab txo nqi.NDT kuj tseem pab ua kom muaj kev nyab xeeb thiab / lossis siv cov khoom siv tau zoo.

Hom NDT txoj kev

1. NDT suav nrog ntau txoj hauv kev uas tuaj yeem siv tau zoo.Raws li cov qauv ntawm lub cev sib txawv lossis cov khoom siv thiab cov hom phiaj, NDT tuaj yeem faib ua kwv yees li hauv qab no:

a) Radiation method:

—— X-ray thiab gamma ray radiographic kuaj;

—— Kev kuaj hluav taws xob;

—— Kev ntsuam xyuas tomography;

—— Neutron radiographic kuaj.

b) Acoustic method:

—— Kev kuaj ultrasonic;

—— Kev kuaj acoustic emission;

—— Electromagnetic acoustic kuaj.

c) Electromagnetic txoj kev:

—— Eddy kev sim tam sim no;

—— Kev kuaj dej ntws tawm.

d) Surface method:

——Magnetic particle kuaj;

—— Kev kuaj kua dej nkag;

—— Kev kuaj pom pom.

e) Txoj kev xau:

—— Kev kuaj pom.

f) Txoj kev Infrared:

—— Infrared thermal kuaj.

Nco tseg: NDT txoj kev tshiab yuav raug tsim thiab siv txhua lub sijhawm, yog li lwm txoj hauv kev NDT tsis suav nrog.

2. Cov txheej txheem NDT cov qauv xa mus rau cov txheej txheem NDT uas tau siv dav thiab paub tab tam sim no.Lawv yog kev kuaj hluav taws xob (RT), kuaj ultrasonic (UT), eddy tam sim no kuaj (ET), sib nqus particle kuaj (MT) thiab kev ntsuas penetrant (PT).
