Cov kev siv NDT feem ntau suav nrog:
- Kev Ntsuas Ultrasonic (UT): Siv los txheeb xyuas qhov delamination, suav nrog, thiab lwm yam kev cuam tshuam sab hauv. UT siv lub piezoelectric sojntsuam txuas nrog lub ntsuas qhov tsis txaus, uas nyob rau hauv nws daim ntawv yooj yim tshaj plaws yog pulser receiver thiab oscilloscope zaub. Lub transducer yog dhau los ntawm cov khoom raug kuaj, uas nws feem ntau yog ua ke los ntawm gel, roj, lossis dej. Cov couplant no yuav tsum tau ua kom zoo xa cov acoustic zog los ntawm lub transducer mus rau hauv ib feem, tab sis tsis tas yuav tsum tau thaum kuaj nrog cov kev tsis sib cuag xws li electromagnetic acoustic transducers (EMAT) los yog laser excitation.
- Radiographic Testing (RT): Siv los txheeb xyuas qhov tsis xws luag, qhov porosity, thiab lwm yam tsis xws luag hauv cov yeeb nkab phab ntsa. Hauv kev ntsuam xyuas hluav taws xob, qhov ntsuas tau muab tso rau ntawm qhov chaw hluav taws xob thiab zaj duab xis (lossis ntes). Qhov sib txawv ntawm cov khoom ntom ntom thiab tuab ntawm qhov ntsuas qhov ntsuas yuav txo qis (piv txwv li, txo) cov hluav taws xob nkag mus los ntawm cov txheej txheem cuam tshuam nrog kev tawg thiab / lossis nqus. Qhov sib txawv ntawm qhov nqus tau raug kaw rau hauv zaj duab xis lossis hauv tshuab hluav taws xob.
-Magnetic Particle Inspection (MPI): Siv tau zoo rau kev kuaj xyuas qhov chaw thiab qhov ze ntawm qhov chaw xws li tawg thiab seams. Cov thev naus laus zis ua haujlwm los ntawm inducing ib magnetic teb nyob rau hauv cov khoom raug kuaj. Yog hais tias muaj qhov chaw nyob ze los yog ze ntawm qhov chaw, qhov sib nqus flux yuav distorted thiab "xws" nyob ib ncig ntawm qhov tsis xws luag. Los ntawm plua plav nrog cov khoom sib nqus zoo xws li ferrous shavings (txawm tias qhuav lossis raug tshem tawm hauv cov kua), cov khoom yuav raug cuam tshuam rau thaj tsam ntawm cov dej ntws tawm, tsim cov cim pom ntawm qhov tsis xws luag.
