Njira Zoyesa Zosawononga Pamakina Owotcherera Apakati pafupipafupi Inverter Spot?

Kuyesa kosawononga (NDT) kumatenga gawo lofunikira pakuwonetsetsa kuti ma welds amapangidwa ndi makina owotcherera apakati pafupipafupi inverter spot.Pogwiritsa ntchito njira zosiyanasiyana za NDT, opanga amatha kuzindikira zolakwika zomwe zingatheke ndi zolakwika mu welds popanda kuwononga zida zowotcherera.Nkhaniyi ikuyang'ana njira zingapo zoyesera zosawononga zomwe zimagwiritsidwa ntchito pamakina owotcherera ma frequency inverter malo ndikukambirana kufunikira kwawo pakutsimikiza kwabwino.

1. Kuyang'anira Zowoneka: Kuyang'anira zowoneka ndi njira yofunikira koma yofunikira ya NDT yomwe imaphatikizapo kuyang'ana zowotcherera ndi madera ozungulira kuti muwone zolakwika zapamtunda, zosiya, kapena zolakwika zina zowoneka.Oyang'anira aluso amagwiritsa ntchito zida zowunikira zowunikira ndi kukulitsa kuti aziyang'ana bwino zowotcherera ndikuzindikira chilichonse chomwe chili ndi vuto, monga ming'alu, porosity, kapena kusakanizika kokwanira.
2. Kuyesa kwa Radiographic (RT): Kuyesa kwa radiographic kumagwiritsa ntchito ma X-ray kapena gamma ray kuti awone momwe ma welds amapangidwira.Mwanjira iyi, filimu ya radiographic kapena chojambulira digito imagwira ma radiation opatsirana, ndikupanga chithunzi chomwe chimawonetsa zolakwika zamkati, monga voids, inclusions, kapena kusowa kwa kulowa.Kuyesa kwa radiographic kumapereka chidziwitso chofunikira pamtundu ndi kukhulupirika kwa ma welds, makamaka muzowotcherera wandiweyani kapena zovuta.
3. Ultrasonic Testing (UT): Mayeso a Ultrasonic amagwiritsa ntchito mafunde amphamvu kwambiri kuti azindikire zolakwika zamkati ndikuyesa makulidwe a ma welds.Potumiza mafunde akupanga m'dera la weld ndikuwunika zizindikiro zowonekera, zida za UT zimatha kuzindikira zolakwika monga ming'alu, voids, kapena kuphatikizika kosakwanira.UT ndiyothandiza makamaka pozindikira zolakwika zapansi panthaka ndikuwonetsetsa kumveka kwa ma welds muzofunikira kwambiri.
4. Kuyesa kwa Magnetic Particle (MT): Kuyesa kwa maginito ndi njira yomwe imagwiritsidwa ntchito pozindikira zolakwika zapamwamba ndi pafupi ndi pamwamba pazida za ferromagnetic.Mu njira iyi, mphamvu ya maginito imagwiritsidwa ntchito kudera la weld, ndipo tinthu tachitsulo (kaya touma kapena kuyimitsidwa mumadzi) timagwiritsidwa ntchito.Tinthu tating'onoting'ono timasonkhana m'malo omwe maginito amatuluka chifukwa cha zolakwika, zomwe zimawapangitsa kuti aziwoneka pansi pa kuyatsa koyenera.MT ndiyothandiza kuzindikira ming'alu yapamtunda ndi zina zosiyanitsidwa ndi ma welds.
5. Kuyesa kwa Penetrant (PT): Kuyesa kwapakatikati, komwe kumadziwikanso kuti kuyang'ana kolowera kwa utoto, kumagwiritsidwa ntchito kuti azindikire zolakwika zomwe zimasweka pamwamba pa ma welds.Njirayi imaphatikizapo kugwiritsa ntchito utoto wamadzimadzi pamtunda wowotcherera, kuti ulowe mkati mwa vuto lililonse lapamwamba ndi capillary action.Pambuyo pa nthawi yodziwika, utoto wowonjezera umachotsedwa, ndipo wojambula amayikidwa kuti atulutse utoto womwe watsekeredwa.Njirayi imasonyeza zizindikiro za ming'alu, porosity, kapena zolakwika zina zokhudzana ndi pamwamba.

Njira zoyesera zosawononga zimagwira ntchito yofunika kwambiri pakuwunika komanso kukhulupirika kwa ma welds opangidwa ndi makina owotcherera apakati pafupipafupi inverter spot.Kupyolera mu kuyang'ana kowoneka, kuyesa kwa radiographic, kuyesa kwa akupanga, kuyesa kwa tinthu tating'onoting'ono, ndi kuyesa kolowera, opanga amatha kuzindikira ndikuwunika zolakwika zomwe zingatheke popanda kusokoneza kukhulupirika kwa zida zowotcherera.Mwa kuphatikiza njira izi za NDT mumayendedwe awo owongolera, opanga amatha kuwonetsetsa kuti ma welds amakwaniritsa zofunikira komanso zofunikira, zomwe zimatsogolera kuzinthu zotetezedwa komanso zodalirika zowotcherera.
