Iindlela zoVavanyo ezingonakalisiyo koomatshini bokuWelding abaPhakathi beFrequency Inverter Spot?

Uvavanyo olungonakalisi (NDT) ludlala indima ebalulekileyo ekuqinisekiseni umgangatho kunye nokuthembeka kwee-welds eziveliswe ngoomatshini bokuwelda bamabala aphakathi. Ngokusebenzisa iindlela ezahlukeneyo ze-NDT, abavelisi banokubona iziphene ezinokuthi zibe khona kunye neziphene kwi-welds ngaphandle kokwenza umonakalo kumalungu adityanisiweyo. Eli nqaku liphonononga iindlela ezininzi zovavanyo eziqhelekileyo ezingonakalisi ezisetyenziswa kumatshini wokuwelda we-inverter ophakathi kwaye lixoxa ngokubaluleka kwazo kuqinisekiso lomgangatho.

1. Uhlolo olubonakalayo: Uhlolo olubonakalayo yindlela esisiseko kodwa eyimfuneko ye-NDT ebandakanya ukuphonononga ngokubonakalayo i-weld kunye neendawo ezingqongileyo kwizitenxo zomphezulu, ukungaqhubeki, okanye ezinye iziphene ezibonakalayo. Abahloli abanobuchule basebenzisa izixhobo zokukhanyisa ezaneleyo kunye nokwandisa ukuze bahlole ngokucokisekileyo i-weld kwaye bachonge naziphi na izibonakaliso zemiba esemgangathweni, njengokuqhekeka, i-porosity, okanye ukudibanisa okungafanelekanga.
2. Uvavanyo lweRadiographic (RT): Uvavanyo lweRadiographic lusebenzisa ii-X-ray okanye ii-gamma ray ukujonga ubume bangaphakathi bee-welds. Kule ndlela, ifilimu ye-radiographic okanye i-digital detector ithatha i-radiation transmitted, ivelise umfanekiso obonisa iziphene zangaphakathi, ezifana ne-voids, inclusions, okanye ukungabikho kokungena. Uvavanyo lweRadiographic lubonelela ngolwazi oluxabisekileyo kumgangatho kunye nemfezeko yee-welds, ngakumbi kwiiwelds ezinzima okanye ezinzima.
3. Uvavanyo lwe-Ultrasonic (UT): Uvavanyo lwe-Ultrasonic lusebenzisa amaza omsindo we-high-frequency ukuze kubonwe iimpazamo zangaphakathi kunye nokulinganisa ubukhulu be-welds. Ngokuthumela amaza e-ultrasonic kwindawo ye-weld kunye nokuhlalutya izibonakaliso ezibonakalisiweyo, izixhobo ze-UT zinokuchonga iziphene ezifana nokuqhekeka, i-voids, okanye i-fusion engaphelelanga. I-UT iluncedo ngokukhethekileyo ekuboneni iziphene ezingaphantsi komhlaba kunye nokuqinisekisa isandi se-welds kwizicelo ezibalulekileyo.
4. UVavanyo lweMagnetic Particle (MT): Uvavanyo lwemagnethi yemagnethi yindlela esetyenziswa ngokuyintloko ukufumanisa iziphene ezikumphezulu kunye nezikufutshane nomphezulu kwizinto zeferromagnetic. Kulo buchule, umbane wamagnetic usetyenziswa kwindawo ye-weld, kwaye iinqununu zensimbi (mhlawumbi zomile okanye zixhonywe kumanzi) zisetyenziswa. Amasuntswana aqokelelana kwiindawo zokuvuza kwamagnetic flux ezibangelwa ziziphene, ezenza zibonakale phantsi kweemeko zokukhanyisa ezifanelekileyo. I-MT iyasebenza ekuchongeni ukuqhekeka komphezulu kunye nezinye ii-discontinuities kwi-welds.
5. Uvavanyo lwe-Penetrant (PT): Uvavanyo olungena ngaphakathi, olwaziwa ngokuba yidayi yokuhlola ukungena, isetyenziselwa ukufumanisa iziphene eziqhekeza phezulu kwi-welds. Inkqubo ibandakanya ukusebenzisa idayi yolwelo kwi-weld surface, ukuyivumela ukuba ingene kuyo nayiphi na impazamo yomhlaba ngesenzo se-capillary. Emva kwexesha elichaziweyo, idayi engaphezulu iyasuswa, kwaye umphuhlisi usetyenziselwa ukukhupha idayi ebanjwe. Le ndlela ibonisa iimpawu zokuqhekeka, i-porosity, okanye ezinye iziphene ezinxulumene nomphezulu.

Iindlela zokuvavanya ezingonakalisiyo zidlala indima ebalulekileyo ekuvavanyeni umgangatho kunye nokuthembeka kwee-welds eziveliswe ngoomatshini bokuwelda bamabala aphakathi. Ngokuhlola okubonwayo, uvavanyo lweradiyographic, uvavanyo lwe-ultrasonic, uvavanyo lwamasuntswana omagnetic, kunye novavanyo lokungena, abavelisi banokubona kwaye bavavanye iziphene ezinokubakho ngaphandle kokubeka esichengeni ukuthembeka kwezinto ezidityanisiweyo. Ngokubandakanya ezi ndlela ze-NDT kwiinkqubo zabo zokulawula umgangatho, abavelisi banokuqinisekisa ukuba i-welds ihlangabezana nemigangatho efunekayo kunye neenkcukacha, ezikhokelela kwizakhiwo ezikhuselekileyo nezithembekileyo kunye namacandelo.
