Uvavanyo lwe-NDT luthetha ukuba ngaphandle komkhethe okanye ukuchaphazela ukusebenza kwento eboniweyo, engonzakaliyo ekuboneleleni izinto ezingaphakathi embuthweni, ukusetyenziswa kwezinto ezigwenxa zesakhiwo sangaphakathi okanye iziphene zobushushu, isandi, ukukhanya, umbane, umazibuthe kunye nokunye ukuphendula okubangelwa lutshintsho emzimbeni. okanye iindlela zekhemikhali njengendlela yokusebenzisa iteknoloji yanamhlanje kunye nezixhobo, izixhobo, umphezulu womzekelo kunye nengaphakathi lesakhiwo, iipropati, kunye nohlobo lwesiphene, indalo, inani, imilo, isikhundla, ubungakanani, ukuhanjiswa kunye nokutshintsha ukuhlolwa kunye neendlela zokuvavanya .Uvavanyo olungonakalisi sisixhobo esisebenzayo sophuhliso lwamashishini luyimfuneko, kwinqanaba elithile libonisa inqanaba lophuhliso lwemizi-mveliso yelizwe, ukubaluleka kovavanyo olungonakalisi kuye kwaqatshelwa, uhlolo oluphambili lwe-ray (RT), uvavanyo lwe-ultrasonic (uvavanyo lwe-ultrasonic). I-UT), uvavanyo lwe-magnetic particle (MT) kunye novavanyo lwe-liquid penetrant (PT) ezine.Kukho ezinye iindlela ze-NDT zovavanyo lwangoku lwe-eddy (ECT), uvavanyo lwe-acoustic emission (AE), ukucinga nge-thermal / infrared (TIR), ukuvavanywa kokuvuza (LT), ubuchule bokulinganisa intsimi ye-AC (ACFMT), uvavanyo lokuvuza kwemagnethi (MFL), ukubonwa kovavanyo olukude (RFT), ixesha le-ultrasonic yendlela ye-flight diffraction (TOFD) kunye nokunye okunjalo.

Uvavanyo lwe-NDT kukusetyenziswa kwezixhobo ezivakalayo, i-optical, imagnethi kunye neempawu zombane ezinje, ngaphandle kokubandlulula okanye ukuchaphazela ukusebenza kwento yokufumanisa ubukho beziphene okanye ukungalingani ekubhaqweni kwento yovavanyo, kunikwe ubungakanani besiphako, indawo ubunjani kunye nobungakanani bolwazi.Xa kuthelekiswa novavanyo olutshabalalisayo, uvavanyo olungonakalisi lunezi mpawu zilandelayo.Eyokuqala yinto engonakalisi, kuba xa isenziwa ngaphandle kokuphazamisa ukusebenza kokufumanisa ngokusebenzisa into yokufumanisa;okwesibini okubanzi, ekubeni ukufumanisa akukonakaliyo, ngoko ke into inokubonwa i-100% yovavanyo olubanzi, ukuba kuyimfuneko oku kubhaqa okutshabalalisayo akunakwenzeka;eyesithathu inovavanyo olupheleleyo, oluyonakalisayo ngokubanzi lusebenza kuphela kuvavanyo lwemathiriyeli ekrwada, njengobunjineli boomatshini obuqhele ukusetyenziswa kuxinzelelo, ukucinezelwa, ukugoba, njl.njl., zezovavanyo olungonakalisi ukwenziwa kwezinto ezikrwada, iimveliso ezigqityiweyo kunye nokubonelela, ngaphandle kokuba. inkonzo ayilungele ukuyivumela ukuba iqhubeke, ngaphandle koko ayikona ukufumanisa ukutshabalalisa kunye novavanyo olungonakalisi ngaphandle kokulimaza into eza kubonwa ngokusetyenziswa kokusebenza.Ngoko ke, akukhona kuphela izinto ezisetyenziselwa ukwenza inyathelo ngalinye eliphakathi kwinkqubo ye-LSAW yensimbi yombhobho, de kube yimveliso yokugqibela egqityiweyo yokuvavanya lonke, kodwa nakwinkonzo kwisixhobo sokuvavanya.

Ukuhlolwa okubonakalayo kwe-NDT: 1, uhlolo lwe-weld surface defect.Jonga iintanda kumphezulu we-weld, ukungena okungaphelelanga kunye nomgangatho we-weld evuzayo.2, uviwo karhulumente.Qwalasela iintanda, ukuxobuka, intambo, imikrwelo, izibonda, amaqhuma, amabala, umhlwa kunye nezinye iziphene.3, ukuhlolwa komngxuma.Xa iimveliso ezithile (ezifana neempompo zegiya leentshulube, iinjini, njl.njl.) zisebenza, ngokweemfuno zobugcisa zeprojekthi ziya kuba luhlolo olubonakalayo olukude.4, ukuhlolwa kwendibano.Xa kuyimfuneko, kwaye xa kuyimfuneko, kusetyenziswa uhlolo lwendibano yomgangatho wevidiyo ye-endoskophu efanayo enamacala amathathu;okanye inyathelo emva kokuba indibano igqityiwe, khangela iinxalenye kunye namacandelo adityanisiweyo isikhundla ihlangabezana neemeko umzobo okanye iimfuno zobugcisa;ubukho beziphene zendibano.I-5, ukuhlolwa kwezinto ezongezelelweyo.Khangela imveliso ngaphakathi kwe-lumen yothuli olushiyekileyo, izinto zangaphandle kunye nezinye iintsalela.
