Imboni yesimanje isebenza ngesithembiso esilula kodwa esinamandla: izingxenye kufanele zisebenze ngokuphephile, ngokubikezelwayo, futhi isikhathi eside ngangokunokwenzeka. Ukuze kugcinwe leso sithembiso, abakhiqizi bathembela emishinini yokuhlola engonakalisi ukuze bahlole izinto ngaphandle kokuzilimaza. Lawa mathuluzi athuthukile avumela onjiniyela ukuthi bathole amaphutha acashile, balinganise ubukhulu bodonga, futhi baqinisekise ubuqotho bezingxenye ezibalulekile ngaphambi kokuthi zisetshenziswe. Kusukela kumthungo omncane kakhulu epayipini kuya kuma-turbine blade angaphakathi kwenjini yendiza, indima yobuchwepheshe bokuhlola ayikaze ibaluleke kangaka. Lo mhlahlandlela uhlola ukuthi iyini ukuhlola okungonakalisi, imishini ini esetshenziswayo, isetshenziswa kuphi, nokuthi ukukhetha kanjani isixazululo esifanele emsebenzini wakho.

Isidingo somhlaba wonke sezinsizakalo zokuhlola sikhule ngokuqhubekayo njengoba izimboni ziqhubekisela phambili amazinga aphezulu okuphepha kanye nemijikelezo yempilo yempahla ende. Izinkampani ezitshala imali kumathuluzi okuhlola athembekile zinciphisa ubungozi bokwehluleka okuyinhlekelele, zigwema ukuma okubizayo komsebenzi, futhi zakha ubudlelwano obuqinile nabalawuli namakhasimende. Ngasikhathi sinye, izinqubo zokukhiqiza zanamuhla ziveza izinselele ezintsha, okuhlanganisa izinto ezinciphile, ama-alloys angajwayelekile, kanye nezakhiwo eziyinkimbinkimbi ezidinga izindlela ezikhethekile. Ukuqonda konke ngenhlangano yokuhlola okungonakalisi ngakho-ke kubalulekile konjiniyela, abaphathi bekhwalithi, kanye namathimba okuthenga ngokufanayo. Kulo mhlahlandlela wonke, sizohlukanisa izindlela ezivame kakhulu, izinzuzo zazo, kanye nemibuzo esebenzayo okufanele uyibuze ngaphambi kokuthenga imishini. Ekugcineni, uzoba nohlaka olucacile lokwakha uhlelo lokuhlola oluvikela abantu bakho, imikhiqizo yakho, nedumela lakho.

Ukuhlolwa okungonakalisi, okuvame ukufushaniswa ngokuthi i-NDT, iqoqo lezindlela zokuhlaziya ezisetshenziselwa ukuhlola izakhiwo zento, ingxenye, noma uhlelo ngaphandle kokudala umonakalo unomphela. Leli gama lihlanganisa konke kusukela ekuhloleni okulula ngamehlo kuya ezinhlelweni zokuskena ezithuthukile ezikhiqiza izithombe ezinobukhulu obuthathu zezakhiwo zangaphakathi. Ngenxa yokuthi into ehloliwe ihlala isebenza ngokugcwele ngemva kokuhlolwa, i-NDT iyindlela ekhethwayo yokulawula ikhwalithi ezimbonini lapho izingxenye kufanele ziqhubeke zisebenza ngokuphephile. Ngokuphambene, ukuhlola okonakalisayo kuhlose ukuphula noma ukushintsha amasampula ukuze kukalwe amandla awo, okusiza ocwaningweni kodwa akunakwenzeka ukukusebenzisa kuyo yonke ingxenye yokukhiqiza. I-NDT, ngakolunye uhlangothi, ingenziwa kumaphesenti angu-100 ezinto ezikhiqiziwe, okuyenza ibe yisisekelo sokuqinisekiswa kwekhwalithi yesimanje. Lo mkhakha kwesinye isikhathi ubizwa ngokuthi ukuhlolwa okungonakalisi noma ukuhlolwa okungonakalisi, futhi la magama asetshenziswa ngokushintshana ezimweni eziningi zobunjiniyela.

Isiyalo siye sathuthuka kakhulu kusukela ezinsukwini zaso zokuqala, lapho abahloli babethembele kakhulu emehlweni, izando, namathuluzi alula ukuthola ukukhubazeka. Namuhla, izinzwa zedijithali, ukuhlaziywa ngekhompyutha, namarobhothi azenzakalelayo seziguqule indlela ochwepheshe abenza ngayo ukutholwa kokukhubazeka nokuhlolwa kwesakhiwo. Kungakhathaliseki ubuchwepheshe, yonke indlela ye-NDT inenhloso eyodwa eyisisekelo: ukuqoqa ulwazi olunembile ngesimo sezinto ngaphandle kokulimaza ukusebenza kwazo. Indlela ngayinye isebenza ngomgomo ohlukile wefiziksi, njengamagagasi omsindo, izinkambu zikazibuthe, imisebe, noma ukusebenza kwe-capillary, okuchaza ukuthi kungani kungekho mshini owodwa ongaxazulula zonke izinkinga zokuhlola. Uhlelo oluphelele lokuhlola luvame ukuhlanganisa izindlela eziningi, ngoba ngayinye inamandla nokulinganiselwa kwayo okukhethekile. Ukuqonda le migomo yisinyathelo sokuqala ekukhetheni imishini efanele yokuhlola engenabungozi kunoma yisiphi isicelo, futhi yilolu lwazi ncamashi oluhlukanisa amaqembu asezingeni eliphezulu kwezobuchwepheshe kwabanye.

Imakethe yemishini yokuhlola engenabungozi ibanzi, futhi ihlanganisa amathuluzi aphathwayo, amakhithi aphathwayo, ama-benchtop analyzers, kanye nezinhlelo zokuskena ezizenzakalelayo ngokuphelele. Ukukhetha phakathi kwalezi zinketho kudinga ukuqonda okucacile komgomo womzimba ngemuva kwendlela ngayinye kanye nohlobo lwesici engaliveza. Izigaba ezilandelayo zichaza imindeni esetshenziswa kakhulu yemishini yokuhlola, kanye nokusetshenziswa kwayo okujwayelekile nezinzuzo zayo. Uma ubuka ikhasi lethu Lemikhiqizo, uzothola eziningi zalezi zobuchwepheshe zimelelwe kanye nemishini yokuhlola izinto ezihambisanayo. Khumbula ukuthi isu elihle kakhulu lokuhlola livame ukuhlanganisa izindlela ezimbili noma ngaphezulu ukuze kumbozwe izinhlobo ezahlukene zezici nezimo zezinto. Isithombe esingezansi sibonisa ukuhlolwa kwensimu okujwayelekile kusenzeka, lapho uchwepheshe esebenzisa ithuluzi le-ultrasonic ukuze ahlole ipayipi lensimbi ngesikhathi sangempela.

Ukuhlolwa kwe-Ultrasonic kusebenzisa amaza omsindo aphakeme kakhulu ahamba ngento ethile abuye abuyele emuva lapho ehlangana nomngcele noma umonakalo. I-transducer ithumela ama-pulses engxenyeni, futhi umshini ukala isikhathi nobukhulu bama-echo abuyayo ukuze unqume ubukhulu noma uthole ukuphazamiseka. Imishini yanamuhla ye-ultrasonic isukela kuma-thickness gauges amancane kuya kuma-phased array systems akwazi ukukhiqiza izithombe ezinemininingwane eziphambene ngesikhathi sangempela. Le ndlela inozwela olukhulu, ingena kalula ezingxenyeni eziwugqinsi, futhi isebenza kahle ezinsimbi, kupulasitiki, kuma-composites, nakuma-welds. Ingenye yezinhlobo zemishini yokuhlola engenabungozi eguquguqukayo futhi esetshenziswa kakhulu emhlabeni wonke. Ngenxa yokuthi amaza omsindo adinga i-coupling medium efana ne-gel noma amanzi, ochwepheshe kumele balungiselele indawo futhi balandele izinqubo eziqinile ukuze bathole imiphumela ethembekile.

Ukuhlolwa kwe-Eddy current kuncike ku-electromagnetic induction ukuze kutholakale ukungapheleli ezingaphezulu naseduze nendawo yezinto eziqhubayo. Uma i-coil ethwele i-alternating current ibekwa eduze kwensimbi, ikhiqiza imisinga ejikelezayo edala i-secondary magnetic field elinganisekayo. Imifantu, ukugqwala, kanye noshintsho ekuqhubeni kuyaphazamisa le nkambu, futhi amathuluzi azwela aguqulela lokho kuphazamiseka kube amasignali umhloli angawakala. Amadivayisi e-Eddy current ashesha kakhulu, awadingi uketshezi lokuhlanganisa, futhi afanelekele ukuhlukanisa izingxube zensimbi, ukukala ubukhulu bokumbozwa, kanye nokuhlola amashubhu okushintshanisa ukushisa. Le nqubo ibaluleke kakhulu embonini yezindiza, lapho abahloli kumele bahlole izimbobo ezinkulungwane zama-fastener kanye nezindawo ezingaphezulu ngendlela ephumelelayo. Nokho, ilinganiselwe ezintweni eziqhubayo nasekujuleni okungashoni, okusho ukuthi kumele ihlanganiswe nezinye izindlela ezingxenyeni eziwugqinsi nasekutholeni ukungapheleli kwangaphakathi.

Ukuhlolwa ngemisebe, okwaziwa kakhulu ngokuthi i-industrial X-ray noma i-CT scanning, kusebenzisa imisebe engena emzimbeni ukudala izithombe zesakhiwo sangaphakathi sento ethile. Umthombo wemisebe uqondisa umugqa wemisebe unqamule ingxenye, bese i-detector irekhoda inani lamandla adlulayo, iveze izikhala, ukufakwa kwezinto ezingafanele, nokwehluka kokuminyana. Ama-digital detectors anamuhla kanye nezinhlelo ze-computed tomography zingakwazi ukwakha kabusha amamodeli anezinhlangothi ezintathu zezinto, zinikeze onjiniyela umbono ongakaze ubonwe wezici ezifihliwe. Le ndlela ihamba phambili ekutholeni amaphutha angaphakathi ekusakazweni kwensimbi, ekushiseleni, nasekuhlanganisweni okuyinkimbinkimbi okungafinyeleleki kwezinye izindlela. Ngenxa yokuthi imisebe ingaba yingozi, imishini yokuhlola ngemisebe idinga izinqubo eziqinile zokuphepha, abasebenzi abaqinisekisiwe, namakamelo okuhlola avikelwe kahle. Naphezu kwalezi zimfuneko, ama-X-ray nama-CT scanner ahlala eyithuluzi elibalulekile ezimweni ezinobungozi obukhulu lapho ubuqotho bangaphakathi bubaluleke kakhulu.

Ukuhlolwa kwezinhlayiya zikazibuthe (magnetic particle inspection) yindlela elula kodwa enamandla yokuthola ukona okungaphezulu noma okungaphansi nje kwaphezulu ezintweni ezinamandla kazibuthe njengensimbi nensimbi eqinile. Inqubo iqala ngokwenza ingxenye ibe kazibuthe, bese kufakwa izinhlayiya ezincane zensimbi ezihlangana endaweni lapho kuvuza khona amandla kazibuthe emfucwini noma emgqeni wokuqhekeka. Izinto zokuhlola eziphathwayo zikazibuthe zisetshenziswa kakhulu emakamu omsebenzi, ezindaweni zokwakha, nasezindaweni zokulungisa ngenxa yokuthi zishesha, azibizi, futhi kulula ukuzichaza. Le ndlela isebenza kuphela ezintweni ezingenziwa kazibuthe, ngakho ayikwazi ukusetshenziswa ku-aluminium, ithusi, noma insimbi engagqwali i-austenitic. Uma ihlanganiswa nokuqonda okuhle kokuma kwengxenye, ukuhlolwa kwezinhlayiya kazibuthe kunikeza ukutholwa okuthembekile kwemifantu yokukhathala, ukona kokushisela, nokusha kokugaya. Ukususwa kazibuthe ngendlela efanele ngemva kokuhlola nakho kuyadingeka ukuze kugwenywe ukushiya amandla kazibuthe asele engxenyeni, okungaphazamisa imisebenzi yakamuva.

Ukuhlolwa ngokungena koketsi olunemibala noma olukhanyayo kusetshenziselwa ukwembula imifantu evela ebusweni kanye nokungena komoya ezintweni ezingenamigodi. Uchwepheshe uhlanza ubuso, afake uketsi olungena, aluvumele ukuthi lingene kunoma yimuphi umfantu ovulekile ngaphambi kokususa okweqile bese efaka isithako sokuthuthukisa. Isithako sokuthuthukisa sidonsa uketsi olungena enkingeni, kudale uphawu olubonakalayo olungahlolwa ngaphansi kokukhanya okumhlophe noma ukukhanya kwe-ultraviolet koketsi olukhanyayo. Le ndlela ingenye yezindlela ezindala nezishibhile kakhulu zokuthola imifantu, futhi isebenza cishe kunoma iyiphi into eqinile, kuhlanganise nezinsimbi, ama-ceramics, kanye namanye ama-plastiki. Ithola kuphela imifantu evulekile ebusweni, ngakho izinkinga zangaphakathi zihlala zingabonakali kule ndlela. Amakhithi okuhlola ngokungena koketsi amancane, alula ukuwathutha, futhi afaneleka kahle ekuhloleni endaweni kanye nasekuhloleni emigqeni yokukhiqiza.

Imishini yokuhlola engonakalisi isebenza cishe kuyo yonke imikhakha eyakha, esebenzisa, noma egcina ingqalasizinda ebonakalayo, futhi ukubaluleka kwayo kulele ekuqinisekiseni ikhwalithi ngaphandle kokubambezela umkhiqizo noma ukonakalisa izingxenye eziqediwe. Umkhakha ngamunye ubhekana nezinhlobo ezihlukile zokwehluleka, izingcindezi zokulawula, kanye nezakhiwo zezindleko ezilolonga indlela ukuhlola okusetshenziswa ngayo. Ukuqonda lezi zinhlelo zangempela zokusebenza kusiza abathengi ukuthi babone ukuthi kungani izindlela ezithile zigqama emikhakheni ethile. Izigaba ezingezansi zihlola izimboni eziyinhloko ezincike kubuchwepheshe bokuhlola kanye nezinselele ezithile okumelwe bazinqobe. Njengoba ufunda, qaphela ukuthi izimiso ezifanayo zomzimba ziguqulwa kanjani ukuze zihambisane nezimo nezidingo ezihluke kakhulu. Lolu lwazi luzoba usizo olukhulu uma uxoxa ngezidingo zakho nomhlinzeki wemishini.

Izimboni zokukhiqiza zisebenzisa imishini yokuhlola engonakalisi ezigabeni eziningi, kusukela ezintweni ezingavuthiwe ezifika kuze kube ukuqinisekiswa komkhiqizo wokugcina. Izimboni zensimbi, izindawo zokuncibilikisa insimbi, nezindawo zokubumba zihlola izinsimbi ezingavuthiwe, izinto ezakhiwe, nezingxenye eziqediwe
