Umuceri.1. Uburyo bwo Kugenzura Inganda zidafite ibyuma: Uburyo bwa 2D Matrix Inteko muburyo bwa TRL.

Kode, stanadard, hamwe nuburyo bwagiye buhinduka kugirango yemererwe gukoresha ibizamini bya ultrasonic bipimishije (PAUT) aho kuba RT kugirango bipime austenitis.Bwa mbere bikoreshwa cyane mu nganda zikoresha ingufu za kirimbuzi hashize imyaka igera kuri 15 ishize, hakoreshwa inteko ebyiri (2D) zikoresha ibyuma byifashishwa mu gukwirakwiza amavuta na gaze ndetse n’izindi nganda aho hakenewe igenzura ryihuse, ryizewe kandi ryizewe ryo gusudira hejuru ya austenitis.
Ibikoresho bigezweho byikurikiranya byashyizwe hamwe bifite software yubatswe neza igufasha gushiraho vuba kandi neza, gushiraho no gusobanura 2D matrix array scan utiriwe utumiza mumadosiye yibanze yibikorwa byakozwe na calculatrice yo hanze cyangwa sisitemu yo kugenzura kure ukoresheje software igezweho.software ya PC.
Uyu munsi, tekinoroji yubugenzuzi ishingiye kuri 2D array transducers itanga ubushobozi buhebuje bwo kumenya inenge nudusimba twa axial mubyuma bidafite ingese hamwe nicyuma gisa nicyuma.Ibipimo bya 2D bisanzwe byemewe birashobora gutwikira neza ingano yubugenzuzi bwibyuma bitagira umwanda kandi birashobora kumenya inenge nini kandi nini.
Ubugenzuzi bwa Ultrasound busanzwe bukubiyemo ibice bibiri bya matrice-ebyiri zashyizwe ku bintu bisimburwa n’ibice bisa n’ibice bifite imiterere ihuye na diameter yo hanze yikintu gisuzumwa.Koresha imirongo mike - 1.5 MHz kubudasa bwicyuma kidasa nibindi bikoresho byo kugabanya ibikoresho, 2 MHz kugeza 3,5 MHz kubikoresho bikozwe mubyuma bidafite ibyuma na weld.
Ibice bibiri bya T / R (kohereza / kwakira) bitanga ibyiza bikurikira: ntahantu hegereye “ahantu hapfuye”, kurandura “echo ya echo” iterwa no gutekereza imbere muri wedge, hanyuma amaherezo ukumva neza no kugereranya ibimenyetso-byerekana urusaku (ikimenyetso cyerekana / urusaku).urusaku)) bitewe no kwemeza imirishyo ya T na R.
Reka turebe uburyo bwa PA UT bwo kugenzura ibihimbano bya austenitike idafite ibyuma.
Mugihe ukora igenzura ry'umusaruro, aho kuba RT, igenzura rigomba gutwikira ingano ya weld hamwe nuburebure bwurukuta rwa zone yibasiwe nubushyuhe.Mubihe byinshi, umugurisha wabagurisha azaba ahari.Mu gusudira ibyuma bya karubone, birasabwa gukoresha umurongo wogosha kugirango ugaragaze amajwi yagenzuwe kumpande zombi, mugihe igice cyanyuma cyanyuma gikoreshwa muburyo bwo kubona ibintu biturutse ku nenge ziri kuri beveri.
Mugihe cyumwanya muto, uburyo busa bwogosha bwogukoresha burashobora gukoreshwa mugupima hafi ya beweri yegeranye yicyuma, ariko ntabwo yizewe mugupimisha ukoresheje ibikoresho byo gusudira austenitike.Byongeye kandi, kubyo bita gusudira CRA, hariho ibishishwa birwanya ruswa bitwikiriye kuri diameter y'imbere y'umuyoboro w'icyuma cya karubone, kandi igice cya nyuma cy'icyuma gisimbuka insinga z'umusaraba ntigishobora gukoreshwa neza.
Reka turebe uburyo bwo kumenya uburyo dukoresheje ibikoresho bya UT byoroshye na software, nkuko bigaragara ku gishushanyo 1.
Dual 2D array transducers itanga dogere 30 kugeza kuri 85 P-wave yamenetse imirasire ishobora gukoreshwa muburyo bwuzuye.Kubyimbye byurukuta kuva kuri 15 kugeza kuri 50 mm, imirongo kuva kuri 1.5 kugeza kuri 2,25 MHz ifatwa nkibikwiye, bitewe na attenuation ya substrate.
Muguhindura inguni ya wedge hamwe niboneza ryibikoresho bya array probe, intera nini yingingo zishobora kwangirika zishobora kubyara neza nta lobes zifitanye isano (Ishusho 2).Ikirenge cya wedge node mu ndege yibibaho kiragabanywa, bituma aho gusohoka kumurambararo kuba hafi ya weld bishoboka.
Imikorere ya 2.25 MHz 10 x 3 yuburyo bubiri bwa array muburyo bwa TRL yasuzumwe kuburebure bwa mm 25 z'uburebure bwa 304 ibyuma bitagira umuyonga weld.Ikigereranyo cyikizamini cyari gifite ubuso bwa V busa nubuso bwa "as-weld" kandi bwarimo inenge nyazo zanditse neza zisa neza na weld.
Umuceri.3. Ikomatanyirizo ryicyiciro cya array kubisanzwe bisanzwe 2.25 MHz 10 x 3 Dual Array (TRL) array kuri 304 icyuma kidafite ingese.
Ku mutini.3 yerekana amashusho yamakuru ya PAR ahuriweho kumpande zose zo kugabanuka (kuva 30 ° kugeza 85 ° LW) muburebure bwose bwa weld.Ikusanyamakuru ryakozwe ku nyungu nkeya kugirango birinde kuzura inenge zigaragaza cyane.16-biti yo gukemura itanga uburenganzira bworoshye bwo kugenera uburyo butandukanye bwinenge.Ibisobanuro byamakuru birashobora koroherezwa mugushira neza icyerekezo cya shitingi.
Ishusho yinenge imwe yaremye ikoresheje dataset imwe ihuriweho irerekanwa mumashusho 4. Reba ibisubizo:
Niba udashaka kuvanaho icyuma mbere yubugenzuzi, ubundi buryo bwo kugenzura burashobora gukoreshwa kugirango hamenyekane ibice bya axial (transvers) mumashanyarazi: imiyoboro imwe ya array array irashobora gukoreshwa muburyo bwa pulse echo kugirango "ihindurwe" icyuma gisudira Ijwi riva munsi Nkuko urumuri rwijwi rukwirakwiza cyane cyane muri substrate, umuraba wogosha urashobora kumenya neza inenge kuruhande rwegereye.
Byaba byiza, gusudira bigomba kugenzurwa mu byerekezo bine (Isanamu 5) kandi bigasaba imigozi ibiri ihuriweho kugenzurwa uhereye ku cyerekezo gitandukanye, ku isaha no ku isaha.Ukurikije inshuro nubunini bwibintu byihariye bigize umurongo, inteko ya wedge irashobora gutezimbere kugirango ibone inguni zo kugabanuka kuva 40 ° kugeza 65 ° ugereranije nicyerekezo cya scan axis.Imirasire irenga 50 igwa kuri buri selire ishakisha.Igikoresho gihanitse cyo muri Amerika PA hamwe na calculatrice yubatswe irashobora gukemura byoroshye ibisobanuro byamahame yo kwibanda kumategeko hamwe na skike zitandukanye, nkuko bigaragara ku gishushanyo cya 6.
Mubisanzwe, imirongo ibiri ikurikiranye ya cheque ikoreshwa mugupfuka byuzuye umubare wa cheque.Imyanya ya axial yimirongo ibiri ya scan igenwa kuva muburebure bwumuyoboro nubugari bwumutwe weld.Umurongo wa mbere wo gusikana ugenda wegereye bishoboka kugera ku nkombe ya weld, ugaragaza inenge ziri mu mizi ya weld, naho umurongo wa kabiri wo gusikana urangiza gukwirakwiza HAZ.Agace shingiro ka probe node kazashyirwa mubikorwa kugirango aho gusohoka kumurambararo yegere hashoboka kugeza kumano yikamba ntagaragaza imbere imbere muri wedge.
Ubu buryo bwo kugenzura bwagaragaye ko bugira akamaro kanini mugutahura inenge za axial ziyobowe.Ku mutini.7 yerekana ishusho yicyiciro cyafashwe ku gice cya axial mu cyuma kitagira ingese: inenge zabonetse ku mpande zinyuranye kandi SNR irashobora kugaragara.
Igicapo 7: Ikomatanyirizo ryikurikiranya ryibice byerekeranye nigice cya axial mugusudira ibyuma bidafite ingese (inguni ya SW itandukanye).
Inyungu za PA UT zateye imbere nkuburyo bwa radiografiya zikomeje kwitabwaho muri peteroli na gaze, kubyara amashanyarazi, inganda nizindi nganda zishingiye kubigenzurwa byizewe byo gusudira austenitis.Mu buryo nk'ubwo, ibikoresho bya PA UT byuzuye, ibikoresho bikomeye bya firime hamwe na 2D array probe ikomeje gukora iri genzura rihendutse kandi neza.
Guy Maes ni umuyobozi wa Zetec ushinzwe kugurisha UT.Uburambe bwimyaka irenga 25 mugutezimbere no gushyira mubikorwa uburyo bugezweho bwa ultrasound, gusuzuma ubushobozi no guteza imbere software.Ukeneye ibisobanuro birenzeho, hamagara (425) 974-2700 cyangwa usure kuri www.zetec.com.
Ibirimo biterwa inkunga ni igice cyihariye cyishyuwe aho amasosiyete yinganda atanga ubuziranenge, butabogamye, butari ubucuruzi kubintu bishishikaje abumva neza.Ibintu byose byatewe inkunga bitangwa namasosiyete yamamaza.Ushishikajwe no kwitabira igice cyatewe inkunga?Menyesha uwuserukira.
Kuberako ibibazo bikunze kugaragara mugihe cyo gusuzuma amabwiriza, ni ngombwa kuruta ikindi gihe cyose gusobanukirwa amahame yo gucunga impinduka.Uru rubuga ruganira ku mahame rusange yo gucunga impinduka, uruhare rwayo nkigice cyingenzi cya sisitemu yo gucunga ubuziranenge (QMS), nubusabane bwayo nibindi bikorwa byingenzi byemeza ubuziranenge nko gukosora / gukumira (CARA) n'amahugurwa.
Twiyunge natwe kugirango twige uburyo ibisubizo bya 3D metrology biha abigenga nababikora bigenga kugenzura kugendana kugirango babone ibyo bakeneye mugupima ubushobozi bwabo 75%.Muri iki gihe cyihuta cyane ku isoko, ubucuruzi bwawe bugomba kuba bushobora gukoresha ikoranabuhanga rigezweho kugirango rikureho ibintu bitoroshye, bitezimbere akazi, kandi byongere umusaruro.
Tanga icyifuzo cyo gusaba (RFP) kumugurisha wahisemo hanyuma ukande buto isobanura ibyo ukeneye.
