Internal Quality Testing

Txhawm rau kom ntseeg tau qhov zoo ntawm cov castings, ntau txoj hauv kev tau ua haujlwm txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua kom zoo, nws raug nquahu kom siv ntau txoj hauv kev los xyuas kom meej qhov zoo ntawm cov castings. Cov txheej txheem no suav nrog:

X-Ray Radiography:Cov txheej txheem no siv X-rays los tsim cov duab ntawm cov qauv sab hauv ntawm lub casting. Nws muaj txiaj ntsig zoo hauv kev txheeb xyuas cov kab nrib pleb sab hauv, porosity, thiab suav nrog.

Kev kuaj ultrasonic (UT):Ultrasonic nthwv dej yog kis los ntawm cov casting, thiab cov reflections yog soj ntsuam los txheeb xyuas tej yam sab hauv discontinuities los yog flaws.

Xam Xaj Tomography (CT) Scanning: Daim ntawv tshaj tawm ntawm X-ray hluav taws xob uas muab cov duab 3D ntawm cov casting, tso cai rau cov ncauj lus kom ntxaws ntawm cov yam ntxwv sab hauv.

Cov txheej txheem soj ntsuam zoo raupeev castingsFeem ntau suav nrog: Kev Tshawb Fawb Txog Kev Tshawb Fawb,X-Ray Radiography thiab CT Scanning.

 

Kev kuaj tsis yog kev puas tsuaj (NDT)

Txoj kev kuaj tsis muaj kev puas tsuaj yog qhov tseem ceeb rau kev ntsuas qhov zoo ntawm cov castings yam tsis muaj kev puas tsuaj rau qhov chaw. Cov txheej txheem NDT feem ntau suav nrog:

Magnetic Particle Testing (MPT): Txoj kev no suav nrog kev sib nqus casting thiab siv cov khoom ferrous rau saum npoo. Txhua qhov chaw lossis qhov chaw ze ze yuav ua rau cov khoom sib sau ua ke, ua rau lawv pom hauv lub teeb ultraviolet.

Dye Penetrant Testing (DPT): Ib qho kua dye yog siv rau saum npoo ntawm qhov casting. Tom qab ib lub sijhawm nyob hauv lub sijhawm, cov xim ntau dhau raug tshem tawm, thiab tus tsim tawm raug siv. Txhua yam tsis xws luag yuav ua rau cov zas xim nkag mus, nthuav tawm cov flaws.

Eddy Current Testing (ECT): Txoj kev no siv electromagnetic induction los xyuas qhov chaw thiab qhov chaw ze ntawm cov khoom siv hluav taws xob.

 

Cov ntawv thov thiab cov txheej txheem tshuaj xyuas zoo sib xws

Ntau hom kev castings xav tau kev tshuaj xyuas tshwj xeeb raws li lawv daim ntawv thov thiab cov khoom siv. Nov yog qee qhov piv txwv:

Automotive Cheebtsam: Cov khoom tseem ceeb xws li lub cav thaiv, lub tog raj kheej taub hau, thiab cov khoom raug tshem tawm feem ntau raug tshuaj xyuas siv cov duab hluav taws xob xoo hluav taws xob thiab kuaj ultrasonic kom ntseeg tau tias lawv tuaj yeem tiv taus kev ua haujlwm nyuaj.

Aerospace Qhov Chaw: Vim muaj kev ruaj ntseg nruj, aerospace castings raug soj ntsuam nruj heev siv CT scanning thiab kuaj ultrasonic los xyuas kom meej qhov siab tshaj plaws ntawm kev ncaj ncees thiab kev ntseeg siab.
