Hlau Phaj & Weld Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT) - Kev Pabcuam Ua Haujlwm Zoo

Hlau daim hlau thiab cov pob qij txha welded yog qhov tseem ceeb tshaj plaws ntawm kev thauj khoom -cov kabmob hauv cov qauv steel, txuas hniav, cov hlab ntsha siab, cov kav dej, cov tubrog nkoj engineering thiab cov khoom siv kho tshuab. Weld defects thiab sab hauv phaj flaws yog lub ntsiab ua rau kev ua hauj lwm qaug zog tsis ua hauj lwm, to, deformation thiab tam sim ntawd puas thaum lub sij hawm ntev - kev pab cuam. Tsis yog-kev kuaj kev puas tsuaj (NDT) muab kev pov thawj zoo zoo yam tsis muaj kev puas tsuaj rau cov khoom ua haujlwm, thiab tau dhau los ua cov txheej txheem tswj xyuas zoo rau kev lees paub thoob ntiaj teb steel engineering, kev xa khoom hauv Hoobkas thiab hauv - kev tshuaj xyuas kev nyab xeeb.

Common Hidden Defects hauv Steel Phaj & Welds

Thaum lub sij hawm steel phaj dov, txiav, sib dhos thiab vuam txheej txheem, ntau yam khoom siv thiab kev ua haujlwm tsis zoo tuaj yeem tshwm sim, suav nrog porosity, slag suav nrog, nkag tsis tiav, tsis muaj fusion, tawg, delamination, voids thiab vuam residual defects. Feem ntau cov micro- qhov tsis xws luag tsis tuaj yeem pom los ntawm kev tshuaj xyuas qhov muag, tab sis yuav txuas ntxiv nthuav dav hauv kev hloov pauv, kev vibration thiab corrosive ib puag ncig, thaum kawg ua rau tag nrho cov qauv tsis ua haujlwm. Yog li ntawd, kev tshuaj ntsuam xyuas NDT tus qauv yog qhov tseem ceeb rau kev ua kom ntev - lub sij hawm kev nyab xeeb ntawm cov qauv.

Peb Tag Nrho NDT Kev Tshawb Fawb Tshuab

1. Kev Ntsuas Ultrasonic (UT)

Ultrasonic kuaj yog txoj kev siv dav tshaj plaws rau steel phaj thiab vuam sab hauv kev kuaj pom. Nws yog tsuas yog siv rau cov hlau tuab, tag nrho kev nkag mus welds, taub qab welds thiab T-joint welds. UT tuaj yeem txheeb xyuas cov kab nrib pleb sab hauv, delaminations, suav nrog, porosity thiab tsis tiav fusion defects. Nrog rau qhov tob tob tob thiab siab rhiab heev, nws yog qhov tsim nyog rau cov khoom siv raw khoom tuaj xyuas, ua tiav qhov kev ntsuam xyuas vuam zoo thiab hauv - kev pabcuam kev ua haujlwm re- kev tshuaj xyuas, ua raws li ISO 16810, ISO 16811 thiab ASTM A388 cov qauv.

2. Kev kuaj hluav taws xob (RT)

RT siv X-ray lossis gamma-ray nkag mus rau qhov muag pom qhov pom ntawm qhov tsis xws luag morphology ntawm welds thiab nyias steel daim hlau. Nws muaj txiaj ntsig zoo rau kev kuaj xyuas qhov tsis xws luag xws li porosity, slag inclusion thiab incomplete penetration. RT muab cov ntaub ntawv khaws tseg mus tas li, uas yog txoj kev soj ntsuam zoo tshaj plaws rau kev lees paub engineering, cov haujlwm xa tawm thiab thib peb -kev txiav txim siab zoo, ua raws li ISO 17636 thiab ASTM E1000.

3. Magnetic Particle Testing (MT)

MT yog siv rau saum npoo thiab ze ntawm - qhov chaw kuaj pom ntawm ferromagnetic steel daim hlau thiab welds. Nws tuaj yeem pom cov kab nrib pleb me me, sib tsoo cov kab nrib pleb, cov kab nrib pleb qaug zog thiab cov vuam deg tsis zoo uas nyuaj rau kev txheeb xyuas los ntawm kev pom kev pom. Nws nta siab rhiab heev, nrhiav kom tau ceev ceev thiab ruaj khov, haum rau ua ntej - kev tshuaj xyuas thiab kev saib xyuas ntawm cov khoom siv hlau, raws li ISO 9934 thiab ASTM E709.

4. Liquid Penetrant Testing (PT)

PT siv tau rau txhua yam tsis yog- cov ntaub ntawv hlau ntxeem tau, suav nrog cov hlau tsis muaj steel hlau thiab tsis yog- cov hlau nplaum hlau nplaum. Nws tuaj yeem paub meej tias txhua qhov qhib - rau- qhov tsis xws luag xws li cov kab nrib pleb zoo, pinholes thiab nto fissures. Nws yog dav siv rau kev tshuaj ntsuam xyuas qhov chaw siab ntawm - cov khoom siv txheem, cov hlab ntsha siab thiab cov qauv marine steel, ua raws li ISO 3452 thiab ASTM E165 cov qauv.
