Weld imifantu emkhunjini ocindezelayo iningi lihambisana nokuqhekeka okubandayo okubambezelekile futhi ukusatshalaliswa kubanzi kakhulu.Enkambweni yokukhiqiza umkhumbi wokucindezela kanye nenhlanganisela yensimu ngokunakwa okukhethekile, kodwa ngenxa "yokubambezeleka" kwayo, ngaphansi kwesenzo sokucindezeleka kokuvimbela, ngokuvamile ekuhlolweni konyaka, kusengatholakala ngobuningi.Lapha akuphenyi ukugxiliswa kwengcindezi yendawo, noma ukwelashwa kokushisa akukafiki ngesikhathi, okufanayo nezinye izizathu, kuphela ngenxa yobuqili obunjalo obukhulu, futhi kungase kungavezwa ngokuphelele endleleni yokuthola ukuqhekeka kwendawo okuzoxoxwa ngayo.Imifantu enjalo ephuka phezulu ngokuvamile ngengilazi yokukhulisa noma ngesibonakhulu ingabonwa ngokubonakalayo.Ukuba khona kwayo akugcini nje ukunciphisa amandla e-weld, kodwa futhi ukugxilwa kokucindezeleka kuzoholela entsha, lapho i-workpiece ingumthwalo, okuholela ekutheni enye i-crack izosakazeka ngokushesha, ibangele ukulimala kwengxenye.Ngakho-ke, kwezinye izimo, kuyingozi kakhulu kunezinye izinhlobo ze-macroscopic crack.Ekuhlolweni komkhumbi ocindezelayo, indlela yokuthola ngempumelelo ama-microcracks, ukuthuthukisa izinga lokutholwa kwama-micro-cracks, afakwa ekuhloleni komhloli wesitsha futhi alimale phambi kwenkinga yangempela, kanye nendlela yokuthola ngokunembile kanye nokulinganisa amaphutha ukuze ukusungula uhlelo lokuhlunyeleliswa kwezimilo kubalulekile.

Ukuthuthukiswa okusheshayo kwemboni yesimanje, kunezinhlobonhlobo zokubona ubuchwepheshe, obunamandla nobuthakathaka bakhe.Ngakho-ke indlela yokukhetha ubuchwepheshe bokubona ukuqhekeka obuphumelela kakhulu, izindlela ezihlukahlukene zokuthola kufanele ziqhathaniswe kuqala ukuze kutholwe okungcono kakhulu kubuchwepheshe bokubona indawo efanelekile.Ingase ihlukaniswe ngokuthi: ukuhlolwa okubonakalayo (VT), indlela yokuhlola izinhlayiyana kazibuthe (MT), indlela yokuhlola ukungena (PT), ukuhlolwa kwe-ultrasonic (UT), indlela yokuhlola i-radiographic (RT).

Ukuze kuthuthukiswe izinga lokutholwa kwemifantu emincane, ngendlela eyodwa yokuthola ukuba khona imikhawulo eminingi ngokungenakugwenywa kanye nokushiywa okungenzeka kubangele ukuthi kungabonakali.Ngokuzijwayeza, sikholelwa ukuthi ukulimala okukhulu kumkhumbi ophakathi nendawo nophezulu oshisela ukuhlolwa kwama-microcracks kufanele kube ukusetshenziswa okuphelele kwezindlela zokubona ezihlukahlukene.Abahloli Bemikhumbi abenza ikhomishana yokuhlola kufanele bahlaziye izindaba ezithile, ukusetshenziswa okuphelele kwezindlela zokubona ezihlukahlukene, futhi babonise izikhundla ezibalulekile ezitholiwe;ukuhlola abalimele kufanele futhi kubhekane nezindaba ezithile, ukusetshenziswa okunengqondo kwesayensi yezindlela zokubona ezihlukahlukene, inhloso eqondile.
