Kwishishini lombhobho wensimbi, i-welding yindlela yokudibanisa eqhelekileyo esetyenziselwa ukudibanisa ngokuqinileyo iinxalenye ezimbini zombhobho wensimbi. Nangona kunjalo, ii-welds eziveliswayo ngexesha lenkqubo ye-welding kufuneka zihlolwe ukuqinisekisa umgangatho wazo kunye nokuthembeka. Ngoko ke, sizihlola njani iiweldi zemibhobho yentsimbi? Okulandelayo, ndiza kwazisa iindlela ezininzi zokuhlola eziqhelekileyo kwaye ndiphonononge izinto eziluncedo kunye nezingeloncedo.

Okokuqala, ukuhlolwa kwembonakalo
Ukuhlolwa kwembonakalo yeyona ndlela ilula kwaye inembile, evavanya umgangatho we-weld ngokujonga imilo kunye nomgangatho womphezulu we-weld ngeso lenyama. Xa sihlola inkangeleko, sifanele sinikele ingqalelo kwezi ngongoma zilandelayo:
1. Ubume be-weld: Ngaphantsi kweemeko eziqhelekileyo, i-weld kufuneka ibonise i-uniform kunye nemilo egudileyo ngaphandle kwamaqhuma acacileyo okanye iziphene.
2. Umgangatho womphezulu we-weld: Umphezulu we-weld kufuneka ube mpuluswa, kwaye ungabi naziphene ezifana neentanda kunye ne-pores, kwaye kufuneka kunikwe ingqalelo ukuba kukho nayiphi na i-flux engaxutywanga eseleyo kwi-weld. Nangona kunjalo, ukuhlolwa kwembonakalo kunokubonelela kuphela ngereferensi yendawo kwaye ayikwazi ukubona iziphene ngaphakathi kwe-weld, ngoko ke kuyimfuneko ukudibanisa ezinye iindlela zokuhlola ngokubanzi.

Okwesibini, uvavanyo lwe-radiographic
Uvavanyo lweRadiographic lusetyenziswa ngokuqhelekileyo ukuvavanya indlela engonakalisiyo enokubona iziphene ngaphakathi kweewelds, ezinje ngeentanda, iipores, njl.njl. Iindlela eziqhelekileyo zovavanyo lweradiographic ziquka uvavanyo lweradiographic radioisotope kunye novavanyo lweX-reyi.
1. Uvavanyo lweradiographic yeRadioisotope: Le ndlela isebenzisa ii-radioisotopes njengomthombo wemitha yokubona iziphene ezingaphakathi kwi-welds ngokubona ukuthotywa kwemitha. Le ndlela inesiphumo esihle sokufumanisa, kodwa ngenxa yokusetyenziswa kwezixhobo ze-radioactive, idinga abasebenzi abaqeqeshiweyo ukuba basebenze, kwaye kukho umngcipheko othile wokungcola kokusingqongileyo.
2. Uvavanyo lweX-reyi: Uvavanyo lweX-reyi lusebenzisa umatshini weX-reyi okanye ityhubhu yereyi njengomthombo wokusasazeka kwemitha ukuze kubonwe iziphene ezingaphakathi kwiiwelds ngokufumanisa ukuthotywa kwemitha. Le ndlela ikhuselekile noko xa isetyenziswa kwaye ayinangcoliseko lokusingqongileyo, kodwa izixhobo zibiza kakhulu kwaye zifuna abasebenzi abaqeqeshiweyo ukuba basebenze kwaye batolike iziphumo.
Uvavanyo lweRadiographic lunokubonelela ngolwazi oluchanekileyo malunga neziphene zangaphakathi kwi-welds, kodwa umphumo wokufumanisa kwii-welds ezincinci okanye iziphene ze-weld surface zimbi.

Okwesithathu, uvavanyo lwe-ultrasonic
Uvavanyo lwe-Ultrasonic lusetyenziswa ngokuqhelekileyo indlela yokuvavanya engonakalisiyo efumanisa iziphene ngaphakathi kwe-welds ngokusasazwa kunye nokubonakaliswa kwamaza e-ultrasonic. Uvavanyo lwe-Ultrasonic lunokubona iziphene ezifana nokuqhekeka kunye ne-pores ngaphakathi kwe-weld kwaye inokulinganisa ubungakanani kunye nendawo yeziphene. Iingenelo zovavanyo lwe-ultrasonic kukuba umsebenzi ulula, ixabiso liphantsi, kwaye ukufunyanwa kwexesha langempela kunokwenziwa. Nangona kunjalo, uvavanyo lwe-ultrasonic luneemfuno ezithile zejometri ye-weld kunye nendlela yokusasaza i-wave wave kwaye ifuna uqeqesho kunye nokusebenza kweengcali.

Isishwankathelo, ukuhlolwa kwe-welds yensimbi yombhobho kunokuqhutyelwa ngokuhlolwa okubonakalayo, ukuhlolwa kwe-radiographic, kunye nokuhlolwa kwe-ultrasonic. Iindlela ezahlukeneyo zineenzuzo ezahlukeneyo kunye nokungonakali, kwaye indlela efanelekileyo inokukhethwa ngokweyona meko. Xa uhlola i-weld, kuyimfuneko ukubeka ingqalelo kwiinkcukacha zokusebenza ukuqinisekisa ukuchaneka nokuthembeka kweziphumo zokuhlola. Ngelo xesha, iziphene ze-weld ezifunyenweyo kufuneka zilungiswe kwaye zicutshungulwe ngexesha lokuqinisekisa umgangatho kunye nokhuseleko lombhobho wensimbi.
