Weld iintanda kwinqanawa yoxinzelelo ubukhulu becala zezokwaphuka okulibaziseka okubandayo kwaye usasazo lubanzi kakhulu.Kwinkqubo yokwenziwa kwenqanawa yoxinzelelo kunye ne-field compound ingqwalasela ekhethekileyo, kodwa ngenxa "yokulibaziseka" kwayo, phantsi kwesenzo soxinzelelo lokuthintela, ngokuphindaphindiweyo ekuhlolweni konyaka, kusekho ukufumaneka ngobuninzi.Apha ayiphandi uxinaniso loxinzelelo lwendawo, okanye unyango lobushushu aluloxesha, iyunifomu kunye nezinye izizathu, kuphela ngenxa yobuqili obugqithisileyo, kwaye ayinakuvezwa ngokupheleleyo kwindlela yokufumanisa i-workpiece surface crack kuya kuxoxwa ngayo.Ukuqhekeka komphezulu onjalo iintanda ngokubanzi ngeglasi yokukhulisa okanye ngemakroskopu zinokujongwa ngokubonakalayo.Ubukho bayo abugcini nje ukunciphisa amandla e-weld, kodwa kunye nokugxininiswa koxinzelelo kuya kukhokelela kwintsha, xa i-workpiece ingumthwalo, okubangela ukuba enye i-crack isasazeke ngokukhawuleza, ibangele umonakalo wecandelo.Ngoko ke, kwezinye iimeko, kuyingozi ngakumbi kunezinye iintlobo zokuqhekeka kwe-macroscopic.Ekuhlolweni kwenqanawa yoxinzelelo, indlela yokufumanisa ngokufanelekileyo i-microcracks, ukuphucula izinga lokubona i-microcracks, ebekwe kwi-container yokuhlola i-container kwaye yenzakele phambi kwengxaki yokwenyani, kunye nendlela yokufumana ngokuchanekileyo kunye nokulinganisa iziphene ngokulandelelana. ukuseka inkqubo yokubuyisela kwisimo sangaphambili kubalulekile.

Uphuhliso olukhawulezayo lweshishini lanamhlanje, kukho ubugcisa obuhlukeneyo bokufumanisa, obunamandla kunye nobuthathaka bakhe.Ke indlela yokukhetha eyona teknoloji yobhaqo olusebenzayo, iindlela ezahlukeneyo zokubona kufuneka kuqala zithelekiswe ukufumana eyona ilungileyo kwindawo efanelekileyo yobhaqo lobuchwephesha.Inokwahlulwa ngokufanelekileyo ibe: ukuhlolwa okubonakalayo (VT), indlela yokuvavanya i-magnetic particle (MT), indlela yokuvavanya ukungena (PT), uvavanyo lwe-ultrasonic (UT), indlela yokuhlola i-radiographic (RT).

Ukuze kuphuculwe izinga lokubhaqwa kweentanda ezincinci, ngendlela enye yokubona ubukho ngokungenakuthintelwa imida emininzi kunye nezinto ezishiyiweyo ezinokubangela ukuba zingabhaqwa.Ngokuziqhelanisa, sikholelwa ukuba umonakalo omkhulu kwinqanawa yoxinzelelo oluphakathi kunye noxinzelelo oluphezulu oludibanisa uvavanyo lwe-microcracks kufuneka ibe lusetyenziso olubanzi lweendlela ezahlukeneyo zokubona.Abahloli beenqanawa abaqhuba ikhomishini yokuhlola kufuneka bahlalutye imiba ethile, ukusetyenziswa ngokubanzi kweendlela ezahlukeneyo zokubona, kwaye babonise iindawo eziphambili ezichongiweyo;ukuhlola amanxeba kufuneka kujongane nemiba ethile, ukusetyenziswa kwenzululwazi ngengqiqo yeendlela ezahlukeneyo zokubona, injongo eqinisekileyo.
