Feem ntau siv cov kev sim uas tsis yog kev puas tsuaj raucarbon steel tubesyog: kuaj ultrasonic (UT), kuaj magnetic particle (MT), kua penetrant kuaj (PT) thiab X-ray kuaj (RT).

Kev siv thiab kev txwv ntawm kev kuaj ultrasonic yog:
Nws tsuas yog siv lub zog penetrability thiab zoo directionality ntawm ultrasonic nthwv dej los sau cov kev xav ntawm ultrasonic tsis nyob rau hauv cov xov xwm sib txawv, thiab hloov cov cuam tshuam nthwv dej rau hauv hluav taws xob digital signals ntawm lub vijtsam kom paub txog qhov tsis muaj kev puas tsuaj. Qhov zoo: tsis muaj kev puas tsuaj, tsis muaj kev cuam tshuam rau kev ua tau zoo ntawm cov khoom kuaj xyuas, ntsuas qhov tseeb ntawm cov qauv sab hauv ntawm cov ntaub ntawv opaque, ntau cov ntawv thov kev tshawb nrhiav, haum rau cov hlau, tsis yog hlau, cov ntaub ntawv sib xyaw thiab lwm yam khoom siv; qhov tseeb dua qhov chaw tsis raug; rhiab rau cheeb tsam tsis xws luag, siab rhiab heev, tsis tshua muaj nqi, ceev ceev, tsis muaj teeb meem rau tib neeg lub cev thiab ib puag ncig.

Kev txwv: Ultrasonic nthwv dej yuav tsum tso siab rau kev tshaj tawm thiab tsis tuaj yeem nthuav tawm hauv lub tshuab nqus tsev. Ultrasonic nthwv dej tau yooj yim ploj thiab tawg mus rau saum huab cua. Feem ntau, kev kuaj pom yuav tsum tau siv cov coupplants uas txuas cov khoom kuaj pom, thiab cov xov xwm xws li (deionized dej) yog ib txwm muaj.

Kev siv tau thiab cov kev txwv ntawm kev ntsuas magnetic particle yog:
1. Kev tshuaj xyuas cov khoom sib nqus yog tsim nyog rau kev kuaj xyuas qhov tsis sib xws uas me me ntawm qhov chaw thiab nyob ze ntawm cov khoom siv ferromagnetic, thiab qhov sib txawv yog qhov nqaim heev thiab tsis yooj yim rau kev pom qhov muag.
2. Kev tshuaj xyuas cov khoom sib nqus tuaj yeem kuaj xyuas qhov chaw hauv ntau qhov xwm txheej, thiab tseem tuaj yeem ntes ntau yam ntawm qhov chaw.
3. Cov kab mob xws li cov kab nrib pleb, suav nrog, cov kab plaub hau, cov pob dawb, cov quav, qhov txias kaw thiab xoob tuaj yeem pom.
4. Kev ntsuam xyuas cov khoom sib nqus tsis tuaj yeem ntes cov ntaub ntawv austenitic stainless hlau thiab welds welded nrog austenitic stainless hlau electrodes, thiab nws tsis tuaj yeem ntes cov khoom tsis sib nqus xws li tooj liab, txhuas, magnesium thiab titanium. Nws yog ib qho nyuaj rau nrhiav delaminations thiab folds nrog ntiav khawb ntawm qhov chaw, faus qhov tob, thiab cov ces kaum tsawg dua 20 ° nrog lub workpiece nto.

Qhov zoo ntawm kev tshawb pom kev nkag mus yog: 1. Nws tuaj yeem ntes tau ntau yam ntaub ntawv; 2. Nws muaj rhiab heev; 3. Nws muaj intuitive zaub, yooj yim ua hauj lwm thiab tsawg nrhiav tau tus nqi.
Qhov tsis zoo ntawm kev ntsuas kev nkag siab yog: 1. Nws tsis haum rau kev tshuaj xyuas cov khoom ua haujlwm los ntawm cov ntaub ntawv xoob xoob thiab cov khoom ua haujlwm nrog cov khoom ntxhib; 2. Kev ntsuam xyuas Penetrant tsuas tuaj yeem txheeb xyuas qhov kev faib tawm ntawm qhov tsis xws luag, thiab nws yog qhov nyuaj rau kev txiav txim siab qhov tseeb qhov tob ntawm qhov tsis xws luag, yog li nws yog qhov nyuaj rau kev txheeb xyuas qhov kev ntsuas ntawm qhov tsis xws luag. Cov txiaj ntsig kev tshawb pom kuj tseem cuam tshuam los ntawm tus neeg teb xov tooj.

Kev siv thiab kev txwv ntawm kev kuaj hluav taws xob:
1. Nws yog rhiab heev rau kev tshawb pom ntawm ntim-hom tsis xws luag, thiab nws yooj yim dua rau tus yam ntxwv ntawm qhov tsis xws luag.
2. Radiographic negatives yog ib qho yooj yim khaws cia thiab muaj traceability.
3. Visually tso saib cov duab thiab hom tsis xws luag.
4. Disadvantages Qhov faus qhov tob ntawm qhov tsis xws luag tsis tuaj yeem nyob. Nyob rau tib lub sij hawm, nrhiav kom pom thickness yog txwv. Cov yeeb yaj kiab tsis zoo yuav tsum tau ntxuav tshwj xeeb, thiab nws muaj kev phom sij rau tib neeg lub cev, thiab tus nqi siab.
