Ukuhlola okungabhubhisi (i-NDT) kudlala indima ebalulekile ekuqinisekiseni ikhwalithi nobuqotho bamashisela akhiqizwa imishini yokushisela i-medium frequency inverter spot. Ngokusebenzisa izindlela ezahlukahlukene ze-NDT, abakhiqizi bangakwazi ukubona amaphutha okungenzeka namaphutha kuma-welds ngaphandle kokudala umonakalo ezingxenyeni ezishiselwe. Lesi sihloko sihlola izindlela ezimbalwa ezijwayelekile zokuhlola ezingabhubhisi ezisetshenziswa emishinini yokushisela i-medium frequency inverter spot futhi sidingida ukubaluleka kwazo ekuqinisekiseni ikhwalithi.
- Ukuhlola Okubonwayo: Ukuhlola okubonakalayo kuyindlela eyisisekelo kodwa ebalulekile ye-NDT ehilela ukuhlola ngokubonakalayo indawo eshiselayo kanye nezindawo ezizungezile ukuze kutholakale ukungahambi kahle kwendawo, ukungaqhubeki, noma okunye ukonakala okubonakalayo. Abahloli abanekhono basebenzisa amathuluzi okukhanyisa anele nawokukhulisa ukuze bahlole kahle i-weld futhi bakhombe noma yiziphi izinkomba zezindaba zekhwalithi, njengokuqhekeka, ukubola, noma ukuhlangana okunganele.
- Ukuhlolwa kwe-Radiographic (RT): Ukuhlolwa kwe-Radiographic kusebenzisa ama-X-ray noma imisebe ye-gamma ukuhlola ukwakheka kwangaphakathi kwama-welds. Ngale ndlela, ifilimu ye-radiographic noma umtshina wedijithali uthwebula imisebe edlulisiwe, ikhiqize isithombe esiveza ukukhubazeka kwangaphakathi, okufana nama-voids, inclusions, noma ukungabi khona kokungena. Ukuhlolwa kwe-Radiographic kunikeza ukuqonda okubalulekile kwekhwalithi nobuqotho bamashisela, ikakhulukazi ezindaweni zokushisela eziwugqinsi noma eziyinkimbinkimbi.
- Ukuhlolwa kwe-Ultrasonic (UT): Ukuhlola kwe-Ultrasonic kusebenzisa amaza omsindo wemvamisa ephezulu ukuze kutholwe amaphutha angaphakathi futhi kukalwe ukujiya kwamashisela. Ngokuthumela amagagasi e-ultrasonic endaweni yokushisela futhi ahlaziye amasignali abonisiwe, imishini ye-UT ingakwazi ukubona amaphutha afana nokuqhekeka, ama-voids, noma ukuhlanganiswa okungaphelele. I-UT iwusizo ikakhulukazi ekutholeni amaphutha angaphansi komhlaba nokuqinisekisa ukuzwakala kwama-welds ezinhlelweni ezibucayi.
- Ukuhlolwa Kwezinhlayiyana Zazibuthe (MT): Ukuhlolwa kwezinhlayiyana zikaMagnetic kuyindlela esetshenziswa ngokuyinhloko ukuthola ukonakala okungaphezulu naseduze kobuso ezintweni ze-ferromagnetic. Kule nqubo, inkambu kazibuthe isetshenziswa endaweni yokushisela, futhi izinhlayiya zensimbi (kungaba zomile noma ezimisiwe oketshezini) zisetshenziswa. Izinhlayiya zibuthana ezindaweni zokuvuza kwe-magnetic flux okubangelwa ukukhubazeka, okuzenza zibonakale ngaphansi kwezimo zokukhanya ezifanele. I-MT iyasebenza ekuhlonzeni imifantu engaphezulu nokunye ukungaqhubeki kokushisela.
- I-Penetrant Testing (PT): Ukuhlolwa kwe-Penetrant, okwaziwa nangokuthi ukuhlola kwe-dayi, kusetshenziselwa ukuthola amaphutha aphuka phezulu kumashidi. Inqubo ihilela ukusebenzisa udayi owuketshezi endaweni yokushisela, ukuyivumela ukuthi ingene kunoma yikuphi ukonakala kwendawo ngesenzo se-capillary. Ngemuva kwesikhathi esinqunyiwe, udayi owedlulele uyasuswa, bese kusetshenziswa umthuthukisi ukuze akhiphe idayi ebanjiwe. Le ndlela yembula izinkomba zokuqhekeka, i-porosity, noma amanye amaphutha ahlobene nendawo.
Izindlela zokuhlola ezingabhubhisi zidlala indima ebalulekile ekuhloleni ikhwalithi nobuqotho bamashisela akhiqizwa imishini yokushisela i-medium frequency inverter spot. Ngokuhlola okubonakalayo, ukuhlolwa kwe-radiographic, ukuhlolwa kwe-ultrasonic, ukuhlolwa kwezinhlayiya kazibuthe, nokuhlola okungenayo, abakhiqizi bangathola futhi bahlole amaphutha angenzeka ngaphandle kokuyekethisa ubuqotho bezinto ezishiselwe. Ngokuhlanganisa lezi zindlela ze-NDT ezinqubweni zabo zokulawula ikhwalithi, abakhiqizi bangaqinisekisa ukuthi ama-welds ahlangabezana namazinga adingekayo kanye nokucaciswa, okuholela ekwakhekeni nezingxenye eziphephile nezithembekile.
