Kev kuaj tsis yog kev puas tsuaj (NDT) ua lub luag haujlwm tseem ceeb rau kev tswj xyuas cov hlau zoo. Tsis muaj kev rhuav tshem cov khoom siv raw, NDT kuaj pom qhov tsis xws luag sab hauv thiab qhov chaw zais, zam cov khoom tsis zoo ntws mus rau hauv cov khoom tsim khoom. Ntawm no peb qhia plaub txoj kev siv NDT dav dav rau steel bar, yeeb nkab thiab phaj.
UT-Ultrasonic TestingUltrasonic yoj kuaj pom cov teeb meem sab hauv xws li cov kab nrib pleb sab hauv, suav nrog thiab laminations hauv cov hlau. Dav siv rau seamless yeeb nkab, hnyav phab ntsa raj thiab loj-size steel bar. Feem ntau xyuas subsurface thiab inner-material quality.
PT-Penetrant TestingKev ntsuam xyuas Penetrant pom qhov chaw qhib qhov tsis xws li cov kab nrib pleb. Haum rau tag nrho cov uas tsis yog-porous hlau nto, zoo rau complex-shape Cheebtsam. Nws tsuas tuaj yeem ntes cov teeb meem qhib rau sab nrauv.
MT-Magnetic Particle TestMagnetic particle test ua haujlwm rau ferromagnetic carbon steel thiab low-alloy steel. Nws pom cov kab nrib pleb nyob ze. Tsis siv tau rau cov hlau tsis muaj hlau nplaum lossis npib tsib xee-puag alloy.
ET-Eddy Current TestingEddy tam sim no xeem yog feem ntau siv rau nyias-phab ntsa hlab, ceev-check nto thiab ze-surface imperfections nyob rau hauv loj ntau lawm.
