Tlhahlobo ea Ultrasonic ke mokhoa o atisang ho sebelisoa bakeng sa ho lemoha mefokolo ea ka hare ho li-cylindrical forgings. E le ho netefatsa liphetho tse sebetsang hantle tsa tlhahlobo, ho na le litemoso tse ling tsa bohlokoa tse lokelang ho lateloa.
Taba ea pele, tlhahlobo ea ultrasonic e lokela ho etsoa ho li-cylindrical forgings kamora kalafo ea ho qetela ea austenitizing le kalafo e futhumatsang ea mocheso ho fumana thepa ea mochini oa forgings. Ehlile, ha ho hlokahala, tlhahlobo le eona e ka etsoa pele kapa ka mor'a khatello efe kapa efe e latelang e imollang kalafo ea mocheso.
Taba ea bobeli, ha ho etsoa liteko tsa ultrasonic, ho lokela ho sebelisoa beam ea radial incidence ultrasonic bakeng sa scanning e felletseng. Sena se bolela hore maqhubu a ultrasonic a lokela ho ba ketsahalo ea perpendicular ho bokaholimo bo ka hare ho tloha ho probe ho etsa bonnete ba ho lemoha sebaka sohle se ka hare. Ho sa le joalo, molemong oa ho ntlafatsa ho nepahala ha phumano, bonyane ho lokela ho ba le kamano ea 20% ea bophara ba chip ea probe lipakeng tsa skena tse haufi.
Ho feta moo, forgings e ka ba boemong bo emeng kapa ea hlahlojoa ka ho li beha holim'a lathe kapa rolara bakeng sa ho potoloha. Sena se tiisa hore bokahare bohle bo ka hare bo fumana tšireletso e lekaneng ea ho lemoha.
Nakong ea ts'ebetso e khethehileng ea tlhahlobo, tlhokomelo e lokela ho lefshoa ho boreleli le bohloeki ba bokaholimo ba ka hare ba forging. Bokaholimo ha boa lokela ho ba le likhopo, letlalo le hlephileng la oxide, lithōle, kapa lintho tse ling tse tsoang kantle ho naha ho thibela ho kena-kenana le ho phatlalatsoa le ho amoheloa ha maqhubu a ultrasonic. Ho finyella sena, hoa hlokahala ho sebelisa moemeli oa ho kopanya ka thata ho hokahanya probe sebakeng se ka hare sa forging ho etsa bonnete ba hore phetiso e sebetsang ea ultrasonic.
Mabapi le lisebelisoa, lisebelisoa tsa tlhahlobo ea ultrasonic li kenyelletsa lisebelisoa tsa tlhahlobo ea ultrasonic, li-probes, li-coupling agents le li-block tsa liteko. Lisebelisoa tsena ke senotlolo sa ho netefatsa ho nepahala le ho ts'epahala ha ts'ebetso ea tlhahlobo.
Qetellong, ha ho etsoa liteko tsa ultrasonic, ho amoheloa ha forgings ho ka ahloloa ho latela palo ea likoli, boholo ba sekoli, boemo, kapa motsoako oa tse tharo, joalo ka ha ho hlokahala. Ho sa le joalo, ka lebaka la ho ba teng ha likhutlo tse pota-potileng le mabaka a mang a sebopeho sa sebakeng seo mohato oa li-cylindrical forgings, ha ho hlokahale ho hlahloba likarolo tse itseng tse nyenyane tsa bokaholimo ba sekoti.
Ka kakaretso, tlhahlobo ea ultrasonic ke mokhoa o ka tšeptjoang oa ho bona mefokolo e ka hare ho li-cylindrical forgings. Ho latela litemoso tse kaholimo, tse kopantsoeng le lisebelisoa tse nepahetseng le theknoloji, li ka netefatsa boleng le ts'epahalo ea liforomo le ho fihlela litlhoko tse tsamaellanang tsa tlhahlobo.
