Isiqulatho sokuhlolwa kwesinyithi esingenasici sibandakanya ukusuka kuyilo lomzobo ukuya kwimveliso yentsimbi engenasici kuyo yonke inkqubo yemveliso yezinto, izixhobo, izixhobo, iinkqubo kunye nokuhlolwa komgangatho wemveliso egqityiweyo, yahlulwe yangamanqanaba amathathu: ukuhlolwa kwangaphambili kwe-weld, ukuhlolwa kwenkqubo ye-welding, emva- ukuhlolwa kwe-weld yemveliso egqityiweyo. Iindlela zokuhlola zinokwahlulwa zibe ziimvavanyo ezitshabalalisayo kunye nokufumanisa impazamo engonakalisiyo ngokubhekiselele ekubeni umonakalo owenziwe yimveliso unokwahlulwa ube ngamacandelo amabini.
1.Ukuhlolwa kwensimbi engenasici kwangaphambili
Ukuhlolwa kwangaphambili kwe-welding kubandakanya ukuhlolwa kwezinto eziluhlaza (ezifana nesiseko sezinto, iintonga ze-welding, i-flux, njl.) kunye nokuhlolwa koyilo lwesakhiwo se-welding.
2.Ukuhlolwa kwenkqubo ye-welding yensimbi engenasici
Kubandakanya ukuhlolwa kwenkqubo ye-welding, ukuhlolwa kobungakanani be-weld, iimeko zokulungiswa kunye nokuhlolwa komgangatho wendibano yesakhiwo.
3.Steel stainless welding ogqityiweyo ukuhlolwa imveliso
Kukho iindlela ezininzi zokuhlolwa kwemveliso egqityiweyo emva kwe-weld, esetyenziswa ngokuqhelekileyo ezi zilandelayo:
(1)Ukuhlolwa kwembonakalo
Ukuhlolwa kwembonakalo yamalungu adibeneyo yindlela yokuhlola elula kwaye esetyenziswa ngokubanzi, yinxalenye ebalulekileyo yokuhlolwa kwemveliso egqityiweyo, ngokukodwa ukufumana iziphene kumphezulu we-weld kunye nobukhulu bokutenxa. Ngokubanzi ngokujongwa okubonakalayo, ngoncedo lweesampulu eziqhelekileyo, iigeyiji kunye neeglasi zokukhulisa kunye nezinye izixhobo zokuhlola. Ukuba kukho iziphene kumphezulu we-weld, kunokwenzeka ukuba kukho iziphene ngaphakathi kwe-weld.
(2)Uvavanyo lokuqina
Ukugcinwa kolwelo okanye iigesi kwisitya esidityanisiweyo, i-weld ayiziphene ezixineneyo, njengokuqhekeka okugqobhozayo, iipores, i-slag, i-welded kunye ne-loose tissue, njl., ingasetyenziselwa ukufumana uvavanyo lokuqina. Iindlela zovavanyo lokuqina zezi: uvavanyo lweparafini, uvavanyo lwamanzi, uvavanyo lokugungxulwa kwamanzi.
(3)Uvavanyo lwamandla esitya soxinzelelo
Inqanawa yoxinzelelo, ukongeza kuvavanyo lokutywinwa, kodwa kunye novavanyo lwamandla. Ngokuqhelekileyo, kukho iindidi ezimbini zovavanyo loxinzelelo lwamanzi kunye novavanyo loxinzelelo lomoya. Banokuvavanya kuxinzelelo lomsebenzi wesikhongozeli kunye ne-pipeline weld tightness. Uvavanyo lwe-pneumatic lubucayi kwaye lukhawuleza kunovavanyo lwe-hydraulic, ngelixa imveliso emva kovavanyo ayifuni ukuchithwa, ngakumbi kwiimveliso ezinobunzima bokuhambisa amanzi. Nangona kunjalo, ingozi yovavanyo inkulu kunovavanyo lwe-hydraulic. Xa uqhuba uvavanyo, kufuneka athobele amanyathelo okhuseleko afanelekileyo ukuthintela iingozi ngexesha lovavanyo.
(4)Iindlela ezibonakalayo zokuvavanya
Indlela yokuhlola umzimba kukusebenzisa isenzeko esithile somzimba kumlinganiselo okanye iindlela zokuhlola. Ukuhlolwa kweziphene zezinto eziphathekayo okanye umsebenzi wangaphakathi, ngokuqhelekileyo usebenzisa iindlela ezingonakalisi zokubona iziphene. Ukufumanisa impazamo yangoku engonakalisi i-ultrasonic flaw ubhaqo, ukubonwa kwe-ray flaw, ukubonwa kokungena, ukufumanisa impazamo yamagnetic.
① Ukufunyanwa kweRay
Ukufumanisa i-ray flaw kukusetyenziswa kwemitha yemitha kunokungena kwizinto eziphathekayo kwaye kwizinto eziphathekayo zinempawu zokunciphisa ukufumana iziphene kwindlela yokufumanisa isiphene. Ngokwemitha eyohlukeneyo esetyenziselwa ukufumanisa isiphene, inokwahlulwa ibe yi-X-ray yokubona isiphene, i-γ-ray yokubona isiphene, ukufumanisa impazamo ye-ray ephezulu. Ngenxa yeendlela zayo zokubonisa iziphene zahlukile, ukufunyanwa kwe-ray nganye kwahlulwa ngendlela ye-ionisation, indlela yokujonga isikrini se-fluorescent, indlela yokufota kunye nendlela ye-TV yeshishini. Ukuhlolwa kwe-ray kusetyenziselwa ukuvavanya iintanda zangaphakathi ze-weld, ezingaxutywanga, i-porosity, i-slag kunye nezinye iziphene.
②Uukufumanisa isiphene se-ultrasonic
I-Ultrasound kwintsimbi kunye nezinye i-media media propagation, ngenxa ye-interface kwimidiya eyahlukeneyo iya kuvelisa izibonakaliso, ngoko ingasetyenziselwa ukuhlolwa kweziphene zangaphakathi. Ukuhlolwa kwe-Ultrasonic kuyo nayiphi na into ye-weldment, nayiphi na inxalenye yeziphene, kwaye ingaba nefuthe ngakumbi ekufumaneni indawo yeziphene, kodwa uhlobo lweziphene, imilo kunye nobukhulu kunzima ukucacisa. Ke ngoko ukufumanisa isiphene se-ultrasonic kudla ngokusetyenziswa kunye nokuhlolwa kwe-ray.
③Uhlolo lwemagnethi
Ukuhlolwa kwemagneti kukusetyenziswa kwemagnethi yomhlaba wemagnethi yamalungu esinyithi e-ferromagnetic aveliswa kukuvuza kwemagnethi ukufumana iziphene. Ngokweendlela ezahlukeneyo zokulinganisa ukuvuza kwamagnetic, kunokwahlulwa ngokwendlela yomgubo wemagnethi, indlela yokungenisa imagnethi kunye nendlela yokurekhodwa kwemagnethi, apho indlela yomgubo wemagnethi isetyenziswa kakhulu.
Ukubona iziphene zemagneti kunokufumana kuphela iziphene kumphezulu kunye nakufutshane nomphezulu wentsimbi yemagnethi, kwaye kunokwenza uhlalutyo lobungakanani beziphene, kunye nendalo nobunzulu beziphene kunokuqikelelwa kuphela ngokusekelwe kumava.
④Uvavanyo lokungena
Uvavanyo lokungena kukusebenzisa ukungeneka kolwelo oluthile kunye nezinye iipropathi ezibonakalayo ukufumana kunye nokubonisa iziphene, kubandakanya uvavanyo lombala kunye nokufumanisa isiphene se-fluorescence ezimbini, zingasetyenziselwa ukujonga iziphene zemathiriyeli ye-ferromagnetic kunye ne-non-ferromagnetic.
Oku ngasentla yimveliso yensimbi engenasici yokuhlola umxholo wokuhlola i-welding welding equka ukusuka kuyilo lomzobo ukuya kwimveliso yensimbi engenasici kuyo yonke inkqubo yokuvelisa iindlela zokuhlola i-welding welding kunye nemiyalelo.
