Non-Destructive Testing (NDT) ndi njira yomwe imagwiritsidwa ntchito kuzindikira zolakwika zamkati mwazinthu kapena zigawo zake popanda kusokoneza kukhulupirika kwake. Pazinthu zamafakitale monga ma forgings, kuyesa kosawononga kumakhala ndi gawo lofunikira pakuwonetsetsa kuti ali abwino komanso odalirika.
Zotsatirazi ndi njira zingapo zoyeserera zosawononga zomwe zimagwiritsidwa ntchito popanga zinthu:
Ultrasonic Testing (UT): Potumiza mafunde amtundu wapamwamba kwambiri ku forgings, ma echoes amapezeka kuti adziwe malo, kukula, ndi morphology ya zolakwika zamkati. Njirayi imatha kuzindikira ming'alu, pores, inclusions, ndi zina zomwe zimapangidwira.
Kuyesa kwa Magnetic Particle (MT): Pambuyo pogwiritsa ntchito mphamvu ya maginito pamwamba pa phula, maginito particles amabalalika pamenepo. Ngati pali ming'alu kapena zolakwika zina zomwe zilipo, maginito a maginito amasonkhana pazilemazi, motero amaziwona.
Kuyeza kwa Liquid Penetrant Testing (PT): Kuphimba pamwamba pa poto ndi madzi otsekemera kuti mudzaze ndi zolakwika ndikuzichotsa pakapita nthawi. Kenaka, wothandizira chitukuko amagwiritsidwa ntchito kuti alole madzi otsekemera kuti alowemo ndikupanga zizindikiro zowonekera pa ming'alu kapena malo opanda vuto.
Kuyeza kwa X-ray (RT): Kugwiritsa ntchito ma X-ray kapena gamma ray kuti alowe muzojambula ndikupanga zithunzi pamakanema owonetsa zithunzi. Njirayi imatha kuzindikira zolakwika monga kusintha kwa kachulukidwe ndi ming'alu mkati mwa zokopa.
Zomwe zili pamwambazi zimangotchula njira zingapo zoyeserera zosawononga, ndipo njira yoyenera iyenera kusankhidwa kutengera mtundu wa chinyengo, zofunikira, komanso momwe zinthu ziliri. Kuphatikiza apo, kuyezetsa kosawononga nthawi zambiri kumafunikira maphunziro aukadaulo ndi ogwira ntchito ovomerezeka kuti awonetsetse kukwaniritsidwa bwino komanso kutanthauzira zotsatira.
