Umuceri. 1. Uburyo bwo kugenzura gukora imashini zikora imashini zitagira umugese: Guteranya ibyuma bibiri bya 2D Matrix muri TRL Mode.

Amakode, stanadards, n'uburyo byagiye bihinduka kugira ngo byemererwe gukoresha ibizamini bya ultrasonic bya phased array (PAUT) aho gukoresha RT mu gupima austenitic welds. Byakoreshejwe bwa mbere mu nganda z'ingufu za kirimbuzi hafi imyaka 15 ishize, gukoresha uburyo bubiri bwo gupima bwa (2D) bwakwirakwiriye mu nganda za peteroli na gaze n'izindi nganda aho hakenewe igenzura ryihuse, ryizewe kandi ryizewe rya austenitic welds za attenuation nyinshi.
Ibikoresho bigezweho byo mu bwoko bwa "portable phased array" bifite porogaramu ikomeye yubatswemo igufasha gushyiraho, gushyira no gusobanura vuba kandi neza uburyo bwo gushakisha "2D matrix array scans" utiriwe winjiza dosiye z’amategeko y’ibanze zakozwe hifashishijwe ibyuma bipima amakuru byo hanze cyangwa sisitemu yo kugenzura kure hakoreshejwe porogaramu zigezweho za mudasobwa.
Muri iki gihe, ikoranabuhanga ryo kugenzura rishingiye kuri transducers za 2D ritanga ubushobozi bwo kumenya inenge z’ubugari n’ubugari mu byuma bitanduye n’ibindi bisa. Imiterere ya 2D dual matrix isanzwe ishobora gupima neza ingano y’igenzura ry’ibyuma bitanduye kandi igashobora kumenya inenge z’ubugari n’izisanzwe.
Uburyo bwo kugenzura ibyuma bikoresha ikoranabuhanga rya Ultrasound busanzwe bukoresha imirongo ibiri ya matrices ifite imiterere ibiri ishyirwa ku bice bishobora gusimburwa bifite imiterere ihuye n'umurambararo w'inyuma w'igice kirimo gusuzumwa. Koresha umurongo muto - 1.5 MHz ku byuma bitandukanye byo gusudira n'ibindi bikoresho bigabanya ubukana, kuva kuri 2 MHz kugeza kuri 3.5 MHz ku byuma bikozwe mu buryo bumwe byo gusudira n'ibyuma byo gusudira.
Imiterere ya T/R ebyiri (kohereza/kwakira) itanga ibyiza bikurikira: nta "gace k’urupfu" gahari hafi y’ubuso, gukuraho "amajwi y’urusaku" aterwa n’ibyerekanwa by’imbere mu gice cy’urukiramende, ndetse no kuba urusaku rurushaho kwiyongera no kuba ikimenyetso cy’urusaku (ikimenyetso cy’urusaku/urusaku).) bitewe n’uko imirasire ya T na R ihurira.
Reka turebe uburyo bwa PA UT bwo kugenzura uko ibintu bikorwa mu byuma bitagira umugese.
Mu gihe cyo kugenzura umusaruro, aho gukoresha RT, igenzura rigomba gutwikira ingano y'ubushuhe n'ubugari bwose bw'urukuta rw'agace kagizweho ingaruka n'ubushyuhe. Kenshi na kenshi, umupfundikizo w'ubushuhe uzaba uriho. Mu bushuhe bwa karubone, ni byiza gukoresha imiraba yo gukata kugira ngo ugaragaze ingano igenzurwa ku mpande zombi, mu gihe igice cya nyuma cy'ubushuhe gikunze gukoreshwa kugira ngo haboneke ibimenyetso bidasanzwe bivuye ku nenge ziri ku musego w'ubushuhe.
Ku murongo wo hasi, uburyo nk'ubwo bwo gukata bushobora gukoreshwa mu gupima umusemburo wa hafi w'ibyuma bitagira umugese, ariko ntabwo bwizewe mu gupima hakoreshejwe ibikoresho bya austenitic weld. Byongeye kandi, ku byitwa CRA welds, hari agapira gakingira ingese ku murambararo w'imbere w'umuyoboro w'icyuma cya karuboni, kandi igice cya nyuma cy'icyuma gikingira icyuma cy'umurambararo ntigishobora gukoreshwa neza.
Reka turebe uburyo bwo gutahura ingero hakoreshejwe igikoresho na porogaramu bya UT bitwarwa, nk'uko bigaragara ku Ishusho ya 1.
Udukoresho dutatu twa 2D dutanga imirasire ya P-wave ya dogere 30 kugeza kuri 85 dushobora gukoreshwa mu gutwikira ubwinshi bw'urukuta kuva kuri mm 15 kugeza 50, imirongo iri hagati ya 1.5 na 2.25 MHz ifatwa nk'ikwiriye, bitewe n'uburyo substrate igabanuka.
Mu kunoza inguni ya wedge no gushyiraho imiterere y’ibice bya probe bya array, ubwoko bwinshi bwa refractive angle scan bushobora gukorwa neza nta bice by’uruhande bifitanye isano (Ishusho ya 2). Ikirenge cy’agace ka wedge mu murongo w’ibiza biragabanuka, bigatuma aho umuraba usohoka haba hafi y’aho ucukurwa hashoboka.
Imikorere y'urupapuro rusanzwe rwa 2.25 MHz rwa 10 x 3 rugizwe n'ibice bibiri mu buryo bwa TRL rwapimwe ku bugari bw'urukuta rwa 25 mm rufite icyuma kitagira umugese cya 304. Ingero z'igerageza zari zifite imiterere isanzwe ya V n'imiterere y'ubuso "busutswe" kandi zari zifite inenge nyazo kandi zemewe neza zijyanye n'urupapuro.
Umuceri. 3. Amakuru yashyizwe hamwe mu byiciro ku buryo bwo gupima 2.25 MHz 10 x 3 Dual Array (TRL) ku gikoresho cyo gusudira icyuma kitagira umugozi cya 304.
Ku ishusho ya 3 hagaragara amashusho y'amakuru ya PAR yahujwe ku nguni zose za refraction (kuva kuri 30° kugeza kuri 85° LW) ku burebure bwose bwa weld. Gushakisha amakuru byakozwe ku rwego rwo hasi rwo gukura kugira ngo hirindwe ko hagira inenge nyinshi zigaragara. Uburyo bwo gusubiza amakuru bwa biti 16 butuma habaho igenamiterere rikwiye ryo gukura ku bwoko butandukanye bw'inenge. Gusobanura amakuru bishobora koroshywa no gushyira neza projection shutter.
Ishusho y'inenge imwe yakozwe hakoreshejwe amakuru amwe yahujwe igaragara ku Ishusho ya 4. Reba ibisubizo:
Niba udashaka gukuraho plug mbere yo kuyigenzura, ubundi buryo bwo kuyigenzura bushobora gukoreshwa mu kumenya icyuho cy’imirongo (transverse) mu byuma bisudira imiyoboro: probe imwe y’urutonde rw’imirongo ishobora gukoreshwa mu buryo bwa pulse echo kugira ngo "ihindure" plug y’urutonde rw’imirongo. Umuvuduko w’ijwi uturutse hepfo. Uko icyuma cy’ijwi gikwirakwira cyane cyane muri substrate, imiraba ya shear ishobora kubona neza inenge ziri ku ruhande rwegereye rw’urutonde rw’imirongo.
Byaba byiza, imiyoboro y'amashanyarazi igomba gusuzumwa mu byerekezo bine by'imirasire (Ishusho ya 5) kandi igasaba ko imiyoboro ibiri ingana igenzurwa mu byerekezo bitandukanye, mu buryo bw'isaha no mu buryo bunyuranyije n'isaha. Bitewe n'inshuro n'ingano y'ibintu byihariye by'urutonde, ihuriro ry'imiyoboro y'amashanyarazi rishobora kunozwa kugira ngo ribone inguni zo guhindukira kuva kuri 40° kugeza kuri 65° ugereranije n'icyerekezo cy'umurongo w'isuzuma. Imirasire irenga 50 igwa kuri buri kazu k'ishakisha. Igikoresho cya US PA gifite icyuma cyabugenewe gishobora gukora ku buryo bworoshye gusobanura amategeko y'ibanze afite imiyoboro itandukanye, nk'uko bigaragara ku Ishusho ya 6.
Ubusanzwe, umurongo w’igenzura ugizwe n’imirongo ibiri ukoreshwa kugira ngo upime neza ingano y’igenzura. Aho imirongo ibiri yo gupima iherereye hagenwa uhereye ku bunini bw’umuyoboro n’ubugari bw’umutwe wo gupima. Umurongo wa mbere wo gupima ugenda wegereye cyane impande z’umuyoboro, ukagaragaza inenge ziri ku mizi y’umuyoboro, naho umurongo wa kabiri wo gupima ukarangiza ubwihisho bwa HAZ. Agace k’ibanze k’agace k’igenzura kazanonosorwa neza ku buryo aho umuyoboro usohoka haba hafi cyane y’ikirenge cy’umutwe nta shusho y’imbere igaragara cyane mu gice cy’igenzura.
Ubu buryo bwo kugenzura bwagaragaye ko bufite akamaro cyane mu kubona inenge zo mu ruhande rw’imbere rw’umurambararo zitari zo. Ku ishusho ya 7 hagaragara ishusho y’urutonde rw’ibyiciro byafashwe ku gice cy’imbere cy’umurambararo mu cyuma gikozwe mu cyuma kitagira umuhengeri: inenge zabonetse ku mfuruka zitandukanye kandi SNR nyinshi yashoboraga kugaragara.
Ishusho ya 7: Amakuru yashyizwe hamwe ku buryo bwo gupfunyika kw'imirongo mu byuma bitagira umugozi (inguni zitandukanye za SW n'impande): imiterere isanzwe (ibumoso) n'imiterere y'impande (iburyo).
Ibyiza bya PA UT igezweho nk'uburyo bwo gusimbura radiography bikomeje kwitabwaho mu nganda zikora peteroli na gaze, ingufu z'amashanyarazi, inganda n'izindi zishingiye ku igenzura ryizewe rya austenitic welds. Mu buryo nk'ubwo, ibikoresho bya PA UT byuzuye, firmware ikomeye na probe za 2D array bikomeje gutuma ubu bushakashatsi burushaho kuba bwiza kandi buhendutse.

Ibikubiye mu nkunga ni igice cyihariye cyishyurwa aho ibigo by’inganda bitanga ibikubiye mu nganda bifite ireme, bidafite aho bibogamiye, bitari iby’ubucuruzi ku ngingo zishishikaje abareba ireme. Ibikubiye mu nkunga byose bitangwa n’ibigo byamamaza. Urashaka kwitabira igice cyacu cy’ibikubiye mu nkunga? Vugana n’uhagarariye aho utuye.
Kubera ko ibibazo bikunze kugaragara mu gihe cy'isuzuma ry'amategeko, ni ngombwa cyane kurusha mbere hose gusobanukirwa amahame yo gucunga impinduka. Iyi webinar ivuga ku mahame rusange yo gucunga impinduka, uruhare rwayo nk'igice cy'ingenzi cya sisitemu yo gucunga ubuziranenge (QMS), n'isano ifitanye n'izindi nzira z'ingenzi zo kugenzura ubuziranenge nko gukosora/gukumira (CARA) n'amahugurwa.
Twifatanye natwe kugira ngo twige uburyo ibisubizo bya 3D metrology biha abashushanya n'abakora ibikoresho bigenga kugenzura uburyo bwo gupima ibintu mu buryo butandukanye kugira ngo bagere ku byo bakeneye mu gihe bongera ubushobozi bwabo ku kigero cya 75%. Mu isoko ryihuse rya none, ubucuruzi bwawe bugomba kuba bushobora gukoresha ikoranabuhanga rigezweho kugira ngo bukureho uburyo bwo gukora ibintu mu buryo bwikora, bunoze imikorere, kandi bwongere umusaruro.
Ohereza icyifuzo cyo gusaba icyifuzo (RFP) ku mucuruzi wihitiyemo hanyuma ukande kuri buto igaragaza ibyo ukeneye.
