UHlolo Olubonwayo
Ukuhlola okubonwayo yeyona ndlela yokuqala nelula kakhulu yolawulo lomgangatho wokusaswa. Kubandakanya ukuphononongwa ngokucokisekileyo kwendawo yokuphosa ukuchonga naziphi na iziphene ezibonakalayo ezifana nezi:
Ukuqhekeka komphezulu:Iifassure ezincinci kumphezulu ezingabonisa uxinzelelo lwangaphakathi okanye ukupholisa okungafanelekanga.
I-Porosity:Ubukho bemingxuma emincinci okanye i-voids ngenxa yegesi ebanjwe ngexesha lenkqubo yokuphosa.
Imisruns:Iindawo apho intsimbi etyhidiweyo ayizange izalise ngokupheleleyo i-mold.
Uburhabaxa boMphezulu:Ukuthungwa kwendawo yokuphosa, ekufuneka ihlangabezane nemigangatho echaziweyo yesicelo esijoliswe kuyo.
Uhlolo olubonakalayo ngokuqhelekileyo lwenziwa ngesandla ngabahloli abaqeqeshiweyo besebenzisa izixhobo ezifana neglasi yokukhulisa okanye i-microscopes ukuphucula ukubonwa kweziphene ezincinci.
Uvavanyo lomgangatho wangaphakathi
Ukuqinisekisa umgangatho wangaphakathi we-castings, iindlela ezininzi ziqeshwe ukufumana iziphene ezingaphantsi komhlaba ezingabonakali kwiso lenyama. Ezi ndlela ziquka:
I-X-Rayi yeRadiyografi:Le ndlela isebenzisa ii-X-rays ukuvelisa imifanekiso yesakhiwo sangaphakathi sokuphosa. Isebenza kakhulu ekuboneni iintanda zangaphakathi, i-porosity, kunye ne-inclusions.
Uvavanyo lweUltrasonic (UT):Amaza e-Ultrasonic ahanjiswa ngokuphosa, kwaye izibonakaliso zihlalutywa ukuchonga naziphi na ii-discontinuities zangaphakathi okanye iimpazamo.
I-Computed Tomography (CT) Ukuskena: Ifomu engaphezulu ye-X-ray ye-radiography ebonelela ngomfanekiso we-3D wokuphosa, okuvumela uhlalutyo olunzulu lweempawu zangaphakathi.
Iindlela zokuhlola umgangatho weutyalo malingokuqhelekileyo ziquka:Uhlolo lweDimensional,I-X-Ray Radiography kunye ne-CT Scanning.
Uvavanyo olungangonakalisi (NDT)
Iindlela zokuvavanya ezingonakalisi zibalulekile ekuvavanyeni umgangatho wokusaswa ngaphandle kokwenza umonakalo kumalungu. Ezona ndlela zixhaphakileyo zeNDT ziquka:
Uvavanyo lweMagnetic Particle (MPT): Le ndlela ibandakanya ukwenza imagnethi ukuphosa kunye nokusebenzisa amasuntswana e-ferrous kumphezulu. Naziphi na iziphene ezingaphezulu okanye ezikufutshane ziya kubangela ukuba iinqununu ziqokelele, zenze ukuba zibonakale phantsi kokukhanya kwe-ultraviolet.
UVavanyo lokuNgena kweDayi (DPT): Idayi yolwelo isetyenziswa kumphezulu wokugalela. Emva kwexesha elichaziweyo lokuhlala, idayi engaphezulu iyasuswa, kwaye umphuhlisi usetyenziswa. Naziphi na iziphene ziya kubangela ukuba idayi ikhuphe ngaphandle, ibonise iziphene.
Uvavanyo lwangoku lukaEddy (ECT): Le ndlela isebenzisa i-electromagnetic induction ukuze ibone iziphene ezingaphezulu kunye nezikufutshane nomphezulu kwizinto zokuqhuba.
Izicelo kunye neendlela zokuHlola eziFakelweyo
Iindidi ezahlukeneyo ze-castings zifuna iindlela ezithile zokuhlola ngokusekelwe kwisicelo sabo kunye neempawu eziphathekayo. Nantsi imizekelo embalwa:
Amacandelo ezeMoto: Amalungu abalulekileyo afana neebhloko ze-injini, iintloko ze-cylinder, kunye nezixhobo zokuxhoma zihlala zihlolwe kusetyenziswa i-X-ray radiography kunye novavanyo lwe-ultrasonic ukuqinisekisa ukuba banokumelana noxinzelelo lokusebenza.
Amacandelo e-Aerospace: Ngenxa yeemfuno ezingqongqo zokhuseleko, i-aerospace castings ihlolwe ngokungqongqo usebenzisa i-CT scanning kunye novavanyo lwe-ultrasonic ukuqinisekisa inqanaba eliphezulu lokuthembeka nokuthembeka.
