1. Ukuhlolwa kokubukeka kweukufakwa kwendololwane: ngokuvamile, ukuhlola okubukwayo kuyindlela eyinhloko.Ngokuhlola ukubukeka, kutholakala ukuthi ukukhubazeka kokubukeka kwe-weld kokufakwa kwepayipi le-elbow elishiselwe kutholwa ngengilazi yokukhulisa izikhathi ezingama-5-20 kwesinye isikhathi.Okufana ne-undercut, i-porosity, i-weld bead, i-surface crack, ukufakwa kwe-slag, ukungena kwe-welding, njll. Ubukhulu obuphelele bokushisela bungalinganiswa ngomtshina wokushisela noma ithempulethi.

2. I-NDT yokufakwa kwendololwane: hlola iziphambeko ezifana nokufakwa kwe-slag, imbobo yomoya kanye nokuqhekeka kwe-weld.Ukuhlolwa kwe-X-ray kuwukusetshenziswa kwe-X-ray ukuthatha izithombe ze-weld, ngokusho kwesithombe esibi ukuze kutholakale ukuthi kukhona yini ukukhubazeka ku-weld, inombolo kanye nohlobo lwamaphutha.Njengamanje, ukuhlolwa kwe-X-ray, ukuhlolwa kwe-ultrasonic nokuhlolwa kazibuthe kusetshenziswa kabanzi.Bese ngokwezidingo zobuchwepheshe bomkhiqizo, thola ukuthi i-weld iyafaneleka yini.Kuleli qophelo, igagasi elibonisiwe liyavela esikrinini.Ngokuqhathanisa nokukhomba la magagasi abonisiwe namagagasi avamile, ubukhulu nendawo yokukhubazeka kunganqunywa.Ukuhlolwa kwe-Ultrasonic kulula kakhulu kunokuhlola i-X-ray, ngakho-ke sekusetshenziswe kabanzi.Kodwa-ke, ukuhlolwa kwe-ultrasonic kungahlulelwa kuphela ngesipiliyoni sokusebenza futhi akukwazi ukushiya isisekelo sokuhlolwa.Lapho ugongolo lwe-ultrasonic ludluliselwa kusixhumi esibonakalayo somoya wensimbi, luzohlehla futhi ludlule endaweni yokushisela.Uma kunesici ku-weld, ugongolo lwe-ultrasonic luzobonakala ku-probe nebhere.Ukuhlola kazibuthe kungabuye kusetshenziselwe ukukhubazeka kwangaphakathi kanye nokuqhekeka okuncane kakhulu okungajulile kusuka endaweni yokushisela.

3. Ukuhlolwa kwempahla eyimishini yokufakwa kwendololwane: ukuhlola okungonakali kungathola amaphutha emvelo e-weld, kodwa akukwazi ukuchaza izici zomshini zensimbi endaweni ethinteke ekushiseni.Ngezinye izikhathi ukuhlolwa okuqinile, ukushayisana nokugoba kuyadingeka kumajoyini ashiselwe.Lezi zivivinyo zenziwa ebhodini.Ipuleti yokuhlola kufanele ihlanganiswe ne-longitudinal seam yesilinda ukuze kuqinisekiswe izimo ezifanayo zokwakha.Khona-ke izakhiwo zemishini zepuleti lokuhlola zahlolwa.Ekukhiqizeni okusebenzayo, inhlanganisela yokushisela kuphela yezinga elisha lensimbi ihlolwa kulokhu.

4. Ukuhlolwa kwe-Hydrostatic kanye nokuhlolwa kwe-pneumatic kokufakwa kwe-elbow: emikhunjini yokucindezela okudingeka ivalwe, ukuhlolwa kwe-hydrostatic kanye nokuhlolwa kwe-pneumatic kuyadingeka ukuze kuhlolwe ukuvala uphawu nokucindezela amandla okuthwala ama-welds.Indlela yokujova isitsha ekucindezelweni okusebenzayo kwamanzi noma izikhathi ezingu-1.25-1.5 zokucindezela kokusebenza kwegesi (iningi lomoya) isikhathi esithile, bese uphenya ukwehla kwengcindezi esitsheni, bese uphenya ukuthi kukhona yini yinoma iyiphi into yokuvuza, ukuze kunqunywe ukuthi i-weld ifanelekile yini.
