Koj tau pom Weld Fail. Tam sim no to taub yog vim li cas.
Koj tau nyob ntawd. A clad phaj hla cov pa UT. Cov neeg siv khoom nruab nws. Ces txoj kab nqes los. Ib daim ntawv hlwv. Daim ntawv cog lus ua tsis tiav. Nqi: pua txhiab. Nug koj tus kheej: koj puas tau txheeb xyuas qhov tseeb ntawm daim ntawv cog lus, los yog koj tsuas yog kos ib lub thawv xwb?
Cov ntsiab lus ib leeg-qib UT muab cov lus teb yog / tsis yog rau koj. Rau clad daim hlau - tawg-bonded los yog yob-bonded - tsis txaus. Koj yuav tsum pom lub interface. Phased array UT rau clad phaj daim ntawv cog lus kev txheeb xyuas qhov tseeb cia koj ua raws nraim li ntawd. Nws tsis yog tshiab. Nws yog mature. Txawm li cas los xij feem ntau lub khw tseem cia siab rau ib qho $200 transducer thiab thov Vajtswv.
Nov yog qhov tseeb tiag: yog tias koj daim ntawv cog lus muaj daim ntawv cog lus hnia - qhov twg ob qhov chaw kov tab sis tsis txhob fuse - cov lus UT yuav nco nws. Koj yuav dhau qhov teeb meem phaj. Phaseed array, nrog nws cov nqaj steering thiab ntau txoj cai focal, catches cov tsis xws luag. Kawg ntawm zaj dab neeg.
Vim li cas Bond Integrity tseem ceeb dua li koj xav
Clad daim hlau yog kev sib yuav ntawm ob lub hlau. Carbon steel backing muab lub zog. Ib tug stainless hlau, npib tsib xee hlau alloy, titanium, los yog tooj liab cladding muab corrosion kuj. Tab sis daim ntawv cog lus interface yog qhov txuas tsis muaj zog tshaj plaws.
Yog tias daim ntawv cog lus ntawd tsis ua haujlwm - txawm tias hauv zos - koj lub siab nkoj los yog kub exchanger leaks. Qhov kev tiv thaiv corrosion tau ploj mus. Koj tau txais galvanic corrosion, nrawm nrawm, thiab kev puas tsuaj loj.
Phased array UT rau clad phaj daim ntawv cog lus kev txheeb xyuas qhov tseeb pom peb yam tsis xws luag uas cuam tshuam kev ua haujlwm:
- Disbonds: Ua tiav kev sib cais. Pom tseeb. Tsis tshua muaj.
- Unbonds: Gap ntawm lub interface. Ib nrab. Txaus ntshai.
- Hnia daim ntawv cog lus: Tight contact tsis muaj metallurgical bond. Invisible rau ib lub ntsiab lus UT. Txaus ntshai heev.
Tsis txhob ntseeg kuv? Ntsuam xyuas qhov paub hnia daim ntawv cog lus nrog ib lub ntsiab lus soj ntsuam. Koj yuav tau txais ib daim ntawv dawb huv rov qab-phab ntsa echo. Tom qab ntawd khiav ib theem array S-scan. Koj yuav pom qhov tsis muaj zog interface echo hloov theem. Qhov txawv yog hmo ntuj thiab nruab hnub.
Yuav ua li cas PAUT Beats Conventional UT ntawm Clad Interfaces
Cia peb ua blunt. Ib qho UT yog ib qho rauj. Phased array UT yog scalpel.
Pa UT siv ib lub kaum sab xis, ib focal tob. Nws ua haujlwm ntawm cov phaj tsis sib xws. Clad daim hlau muaj ib qho acoustic impedance mismatch ntawm puag thiab clad txheej. Uas tsis sib haum xeeb distors lub suab beam. Lub rauj tsis yoog.
Phased array UT rau clad phaj daim ntawv cog lus kev txheeb xyuas qhov tseeb siv hluav taws xob beam steering. Koj tuaj yeem tsav lub nqaj ntawm 35 ° txog 75 ° hauv microseconds. Koj tuaj yeem tsom mus rau qhov tob ntawm qhov interface. Koj tuaj yeem luam theej duab ntau lub kaum ntse ntse ib txhij.
Nov yog qhov uas txhais tau tias hauv kev tshuaj xyuas tiag tiag:
- Linear array probes muab rau koj hla ntu (B-scan) raws lub scan axis.
- Matrix array sojntsuam muab cov ntaub ntawv volumetric rau koj. Koj tuaj yeem pom qhov tsis sib haum xeeb me me ntawm ntug ntawm lub titanium-steel clad phaj uas ib qho kev sojntsuam linear yuav nco.
- S-scan (sectorial scan) muab koj ib tug wedge-zoo li tus saib ntawm lub interface. Koj tuaj yeem pom daim ntawv cog lus ntawm txhua lub kaum sab xis.
Kuv tau soj ntsuam lawm 500 clad daim hlau. Kuv tuaj yeem qhia rau koj: matrix array nrog a 5 MHz nruab nrab zaus thiab 60 ° wedge yog qhov chaw qab zib rau feem ntau clad thicknesses (3- 20 hli clad, 10- 100 mm rov qab).
Kev soj ntsuam xaiv: Txhob yuav qhov muag tsis pom
Koj siv tsis tau tus qauv weld soj ntsuam soj ntsuam rau clad phaj daim ntawv pov thawj. Tsis txhob sim.
Nov yog vim li cas. Lub clad interface yog nyob ze rau saum npoo. Koj xav tau kev daws teeb meem ze ze. A 2.25 MHz sojntsuam muab kev nkag mus rau koj tab sis kev daws teeb meem tsis zoo nyob ze ntawm phab ntsa pem hauv ntej. A 10 MHz sojntsuam muab kev daws teeb meem rau koj tab sis raug kev txom nyem hauv austenitic lossis npib tsib xee alloy cladding.
Phased array UT rau clad phaj daim ntawv cog lus kev txheeb xyuas qhov tseeb xav kom ceev faj soj ntsuam thiab xaiv wedge:
- Ntau zaus: 5 MHz yog qhov pib. Rau nyias clad (hauv qab 5 mm) thiab nplua-grained alloys, mus rau 7.5-10 MHz. Rau hnyav clad (dhau 15 mm) los yog coarse nplej (e.g., 316L pov), poob rau 3.5 MHz.
- Element suav: 64 yam tsawg kawg nkaus. 128 cov ntsiab lus rau matrix arrays. Ntau cov ntsiab lus muab rau koj zoo dua beam steering thiab me me focal me ntsis.
- Lub kaum sab xis: 30° mus rau 60 ° wedge. Lub kaum sab xis hloov lub nqaj nkag mus deb ntawm qhov ze-nto qhov chaw tuag. Qhov no yog qhov tseem ceeb rau kev hnia daim ntawv cog lus.
- Focal laws: Siv tsawg kawg 8 focal laws per scan. Tsom ib pab pawg ntawm clad interface, ib qho ntawm nruab nrab-thickness ntawm clad txheej, thiab ib qho ntawm sab nraub qaum. Koj xav ua kom muaj kev nkag siab zoo qhov twg qhov tsis xws luag nkaum.
Kuv tau pom integrators siv a 2.25 MHz 32-cov ntsiab lus sojntsuam nrog 0 ° wedge. Qhov tshwm sim? Lawv nco txhua txoj kev sib hlub. Tsis txhob ua tus soj ntsuam ntawd.
Txhais PAUT Data: A-Scan, B-Scan, C-Scan, S-Scan
Koj yuav tsum paub qhov koj tab tom saib. Ntawm no yog qhov kev sib cais.
