Indlela yokuhlola umgangatho wombhobho ojikelezayo (i-saw) imi ngolu hlobo lulandelayo:

1. Ukugweba kumphezulu, oko kukuthi, ekuhloleni okubonakalayo. Ukuhlolwa okubonakalayo kwamalungu adityanisiweyo yinkqubo elula eneendlela ezahlukeneyo zokuhlola kwaye yinxalenye ebalulekileyo yokuhlolwa kwemveliso egqityiweyo, ngakumbi ukufumana iziphene ze-welding ebusweni kunye nokuphambuka kwe-dimensional. Ngokuqhelekileyo, ijongwa ngamehlo enyama kwaye ihlolwe ngezixhobo ezifana neemodeli eziqhelekileyo, iigeji kunye neeglasi zokukhulisa. Ukuba kukho impazamo kumphezulu we-weld, kunokubakho impazamo kwi-weld.

2. Iindlela zokuhlola umzimba: Iindlela zokuhlola umzimba ziindlela ezisebenzisa izinto ezithile ezibonakalayo zokuhlola okanye zokuvavanya. Ukuhlolwa kweziphene zangaphakathi zemathiriyeli okanye iinxalenye ngokubanzi kwamkela iindlela zovavanyo ezingonakalisi. Ukufunyanwa kwempazamo yeX-reyi yeyona ndlela isetyenziswa ngokuqhelekileyo yovavanyo olungonakalisi lwemibhobho yentsimbi ejikelezayo. Iimpawu zale ndlela yokufumanisa ziyinjongo kwaye zithe ngqo, ixesha lokwenyani lokucinga ngoomatshini beX-reyi, isoftware yokugweba ngokuzenzekelayo iziphene, ukufumana iziphene, kunye nokulinganisa ubungakanani besiphene.

3. Uvavanyo lwamandla omkhumbi woxinzelelo: Ukongeza kuvavanyo lokutywinwa, isitya soxinzelelo sikwaphantsi kovavanyo lwamandla. Ngokwesiqhelo kukho iindidi ezimbini zovavanyo lwehydraulic kunye novavanyo lwe-pneumatic. Bayakwazi ukuvavanya ubuninzi be-weld yeenqanawa kunye nemibhobho esebenza phantsi koxinzelelo. Uvavanyo lwe-pneumatic lubucayi kwaye lukhawuleza kunovavanyo lwe-hydraulic, kwaye imveliso evavanyiweyo ayifuni ukuchithwa, ngakumbi kwiimveliso ekunzima ukuzikhupha. Kodwa umngcipheko wovavanyo uphezulu kunovavanyo lwe-hydraulic. Ngexesha lovavanyo, ukhuseleko oluhambelanayo kunye neendlela zobugcisa kufuneka ziqwalaselwe ukwenzela ukukhusela izingozi ngexesha lovavanyo.

4. Uvavanyo lwe-Compaction: Kwizikhongozelo ezidibeneyo ezigcina ulwelo okanye igesi, akukho ziphene ezixineneyo kwi-weld, njengeentanda ezingenayo, ii-pores, i-slag, i-impermeability kunye nentlangano ekhululekile, njl., engasetyenziselwa ukufumana uvavanyo lokudibanisa. Iindlela zovavanyo loxinaniso zezi: uvavanyo lwe-kerosene, uvavanyo lwamanzi, uvavanyo lwamanzi, njl.

5. Uvavanyo loxinzelelo lwe-Hydrostatic Ipayipi nganye yensimbi kufuneka ifakwe kuvavanyo lwe-hydrostatic ngaphandle kokuvuza. Uxinzelelo lovavanyo luhambelana noxinzelelo lovavanyo P = 2ST / D, apho uxinzelelo lwe-hydrostatic yovavanyo lwe-S yi-Mpa, kunye noxinzelelo lovavanyo lwe-hydrostatic luchongwa yimiqathango ehambelanayo. I-60% yesiphumo esichazwe kumgangatho wemilo. Ixesha lokulungelelanisa: D <508 uxinzelelo lovavanyo lugcinwa kungekho ngaphantsi kwemizuzwana ye-5; d ≥ Uxinzelelo lwe-508 lovavanyo lugcinwa kungekho ngaphantsi kwemizuzwana ye-10.

6. Uvavanyo olungonakaliyo lwemibhobho yensimbi yesakhiwo, i-weld head welds kunye ne-ring joints kufuneka iqhutywe nge-X-ray okanye uvavanyo lwe-ultrasonic. Kwiintsimbi ezijikelezayo zentsimbi ezihanjiswa ngamanzi aqhelekileyo anokutsha, i-100% yeX-reyi okanye uvavanyo lwe-ultrasonic luya kwenziwa. Iiwelds ezijikelezayo zemibhobho yentsimbi ehambisa ulwelo jikelele njengamanzi, ilindle, umoya, umphunga wokufudumeza, njl. njl. kufuneka ihlolwe ngeX-reyi okanye nge-ultrasonic. Inzuzo yokuhlolwa kwe-X-ray kukuba umfanekiso unenjongo, iimfuno zobungcali azikho phezulu, kwaye idatha ingagcinwa kwaye ilandelwe.
