Ukuhlolwa kwe-Ultrasonic kusebenzisa amaza omsindo anemvamisa ephezulu angena ngaphakathi kwento futhi abonise ukungaphumeleli kwangaphakathi, kuyilapho ukuhlolwa nge-radiographic kusebenzisa imisebe egqobhozayo efana ne-X-rays noma i-gamma rays ukudala izithombe zezakhiwo zangaphakathi. Izindlela ze-Ultrasonic zizwela kakhulu ekutholeni iziphambeko eziyizicaba njengemifantu nokungahlangani kahle emathangeni futhi zinikeza imiphumela esheshayo ngaphandle kwengozi yemisebe. Ukuhlolwa nge-radiographic, ngakolunye uhlangothi, kuhle kakhulu ekutholeni iziphambeko ezinomthamo njengezimbotshana nokufakwa kwezinto ezingafanele futhi kukhiqiza izithombe ezihlala njalo ezisiza ukugcinwa kwemibhalo. Ukuhlolwa kwe-Ultrasonic ngokuvamile kudinga ukufinyelela okuqondile endaweni yokuhlola kanye nendawo yokuxhumanisa, kuyilapho izindlela ze-radiographic zingahlola izingxenye zikude. I-Radiography ibandakanya imisebe ye-ionizing, edinga izinyathelo eziqinile zokuphepha kanye nezitifiketi zabasebenzi ezingadingekile ekuhloleni kwe-ultrasonic. Zombili lezi zindlela ziyahlangana, futhi izinhlelo eziningi zekhwalithi zisebenzisa zombili ndawonye ukuze kutholakale iziphambeko ngokuphelele.

Akukho luhlobo olulodwa lwemishini yokuhlola engathola yonke inkinga engaba khona, yingakho inhlanganisela yezindlela ivame ukudingeka ukuze kutholakale ukumboza okuphelele. Imifantu evela ebusweni itholakala kalula kusetshenziswa izindlela zokungena noma zamagnetic particle, kuyilapho izinkinga zangaphakathi ezivulekile zidinga izindlela ze-ultrasonic noma ze-radiographic. Ezinye izinhlobo zemishini zenzelwe izimo ezithile zezinto, njengemishini ye-eddy current yezinto eziqhubayo noma amasistimu e-magnetic particle ezingxenyeni ze-ferromagnetic. Izinkinga ezincane kakhulu emikhawulweni ephezulu yokutholwa zingadinga imishini ekhethekile ephezulu noma izindlela eziningi ezihambisanayo ukuze ziqinisekiswe. Ngakho-ke, uhlelo oluhle lwe-NDT lusebenzisa izindlela eziningi ngobuchule, lukhetha imishini efanele yohlobo ngalunye lwenkinga kanye nenhloso yokuhlola.

Abasebenzi be-NDT ngokuvamile badinga ukugunyazwa ngokusekelwe ezindinganisweni ezaziwayo ezifana ne-ISO 9712 noma i-SNT-TC-1A, eziqinisekisa ulwazi lwabo lwezobuchwephesha namakhono asebenzayo ezindleleni ezithile. Amazinga okugunyazwa asukela ezingeni I, elihlanganisa ukusebenza kwemishini eyisisekelo ngaphansi kokuqondiswa, kuya ezingeni III, elihlanganisa ukuthuthukisa izinqubo nokuqinisekisa abasebenzi abasezingeni eliphansi. Izinga ngalinye lokugunyazwa lidinga inhlanganisela yamahora okuqeqeshwa asemthethweni, ulwazi olubhaliwe lokusebenza, kanye nokuphumelela kokuhlolwa okubhaliwe nokwenzekayo. Izitifiketi ziqondene nomkhuba othile, okusho ukuthi umsebenzi ogunyazwe ekuhloleni nge-ultrasonic akakwazi ukuphatha imishini ye-radiographic ngaphandle kweziqu ezengeziwe. Ukugcina ukugunyazwa ngokuvamile kuhilela ukuqinisekiswa kabusha ngezikhathi ezithile ukuze kuqinisekiswe ukuthi abahloli bahlala benolwazi lwezindlela namazinga ashintshayo. Izinhlangano ezifuna ukwakha amandla e-NDT ngakho-ke kufanele zihlele izindleko zokuqeqeshwa nokugunyazwa ezihambisana nabasebenzi bazo abaqeqeshiwe.

I-Jinan Wangtebei Instrument and Equipment Co., Ltd ingumkhiqizi ohamba phambili wemishini yokuhlola izinto kanye nemishini ehlobene nokuqinisekisa ikhwalithi, enohlu olubanzi lwemikhiqizo evezwe ekhasini labo Lemikhiqizo. Nakuba inkampani yaziwa kakhulu ngemishini yokuhlola yonke into, ama-tensile testers, ama-bending testers, kanye nezinhlelo zokuhlola ukukhathala, futhi bahlinzeka ngezixazululo zokuhlola ezingezekile ezisekela ukuhlolwa okuphelele kwezinto.
