Molao-motheo: Kamora hore lisebelisoa tsa ferromagnetic le li-workpiece li hoketsoe, ka lebaka la ho ba teng ha li-discontinuities, melapo ea matla a khoheli e holim'a metsi le haufi le bokaholimo ba lisebelisoa tsa mosebetsi li kena ho khopame ea lehae, e leng se bakang ho lutla ha matla a khoheli.Likaroloana tsa Magnetic tse kentsoeng holim'a li-workpieces li adsorbed, li etsa matšoao a bonahalang a khoheli tlas'a mabone a loketseng, ka hona li bonts'a sebaka, sebopeho le boholo ba li-discontinuities.
Tšebeliso le meeli:
Tlhahlobo ea likaroloana tsa Magnetic e loketse ho bona li-discontinuity holim'a metsi le haufi le holim'a lisebelisoa tsa ferromagnetic tse nyane haholo ebile li na le likheo tse moqotetsane haholo (joalo ka mapetsong a ka bonoang ka bolelele ba 0.1mm le bophara ba li-micrometer) tseo ho leng thata ho li lemoha. ka pono;E ka boela ea hlahloba lisebelisoa tse tala, lihlahisoa tse feliloeng, lisebelisoa tse felileng, le likarolo tsa ts'ebeletso, hammoho le lipoleiti, profil, liphaephe, mekoallo, likarolo tse cheselitsoeng, likarolo tsa tšepe tse entsoeng ka tšepe le likarolo tsa tšepe tse entsoeng.Litšitiso tse kang mapetsong, li-inclusions, li-hairlines, matheba a masoeu, mameno, li- shuts tse batang le ho lokoloha li ka fumanoa.

Teko ea Penetrant (PT)
Molao-motheo: Ka mor'a hore karolo e ka holimo ea karolo e koahetsoe ka penetrant e nang le li-fluorescent kapa li-coloring dyes, tlas'a ketso ea tube ea capillary, ka mor'a nako e itseng, motho ea kenang ka hare a ka kenella ka har'a mefokolo ea ho bula holimo;Ka mor'a ho tlosa ho kenella ho feteletseng holim'a karolo, moqapi o sebelisoa holim'a karolo.Ka mokhoa o ts'oanang, tlas'a ts'ebetso ea capillary, moqapi o tla hohela motho ea ts'oaretsoeng ka sekoli, 'me ea kenang o tla khutlela ho moqapi.Tlas'a mohloli o itseng oa leseli (ultraviolet kapa khanya e tšoeu), mesaletsa ea penetrant ka sekoli a hlokomela (bosehla bo botala fluorescence kapa bofubelu bo khanyang), ka tsela eo ho lemoha morphology le kabo boemo ba sekoli.
Melemo le meeli:
Teko e kenang ka hare e ka bona lisebelisoa tse fapaneng, ho kenyeletsoa lisebelisoa tsa tšepe le tse seng tsa tšepe;Lisebelisoa tsa Magnetic le tseo e seng tsa makenete;Welding, forging, rolling le mekhoa e meng ea ho lokisa;E na le kutlo e phahameng (e ka fumanoa e le 0.1 μ M sekoli se pharaletseng, e nang le ponts'o e hlakileng, ts'ebetso e bonolo, le litšenyehelo tse tlase tsa ho lemoha.
Empa e khona ho bona feela mefokolo e nang le menyetla e ka holimo 'me ha e tšoanelehe bakeng sa ho hlahloba li-workpieces tse entsoeng ka thepa ea porous le e hlephileng le li-workpieces tse nang le libaka tse thata;Ke kabo ea bokaholimo ba mefokolo feela e ka bonoang, e leng ho etsang hore ho be thata ho tseba botebo ba bofokoli, ho etsa hore ho be thata ho lekola mefokolo ka bongata.Liphetho tsa ho sibolloa le tsona li susumetsoa haholo ke opareitara.
