Mekhoa e tloaelehileng ea tlhahlobo e sa senyeheng ea holi-tubes tsa carbon steelke: tlhahlobo ea ultrasonic (UT), tlhahlobo ea magnetic particle (MT), tlhahlobo ea metsi a phunyeletsang metsi (PT) le tlhahlobo ea X-ray (RT).

Ho sebetsa le mefokolo ea tlhahlobo ea ultrasonic ke:
Haholo-holo e sebelisa ho kenella ka matla le tataiso e ntle ea maqhubu a ultrasonic ho bokella pontšo ea maqhubu a ultrasonic mecheng e fapaneng ea mecha ea litaba, le ho fetola maqhubu a tšitiso hore e be lipontšo tsa elektronike tsa digital skrineng ho lemoha ho lemoha liphoso tse sa senyeheng. Melemo: ha ho na tšenyo, ha ho na tšusumetso ea ts'ebetso ea ntho e hlahlobiloeng, litšoantšo tse nepahetseng tsa sebopeho sa ka hare sa lisebelisoa tsa opaque, mefuta e mengata ea lisebelisoa tsa ho lemoha, tse loketseng lisebelisoa tsa tšepe, tse se nang tšepe, lisebelisoa tse kopantsoeng le lisebelisoa tse ling; boemo bo nepahetseng haholoanyane ba sekoli; e nahanela bofokoli ba sebaka, Kutlo e phahameng, theko e tlase, lebelo le potlakileng, e se nang kotsi ho 'mele oa motho le tikoloho.

Meeli: Maqhubu a Ultrasonic a tlameha ho itšetleha ka mecha ea litaba 'me a ke ke a hasana ka har'a vacuum. Maqhubu a Ultrasonic a lahleha habonolo 'me a hasane moeeng. Ka kakaretso, ho lemoha ho hloka tšebeliso ea li-couplants tse hokahanyang lintho tsa ho lemoha, 'me mecha ea litaba e kang (metsi a deionized) a tloaelehile.

Ho sebetsa le mefokolo ea tlhahlobo ea matla a khoheli ke:
1. Tlhahlobo ea likaroloana tsa Magnetic e loketse ho bona li-discontinuities tse nyane ka boholo holim'a metsi le haufi le bokaholimo ba lisebelisoa tsa ferromagnetic, 'me lekhalo le moqotetsane haholo ebile le thata ho le bona.
2. Tlhahlobo ea likaroloana tsa Magnetic e ka lemoha likarolo maemong a fapaneng, hape e ka lemoha mefuta e fapaneng ea likarolo.
3. Litšitiso tse kang mapetsong, li-inclusions, li-hairlines, matheba a masoeu, mameno, li- shuts tse batang le ho lokoloha li ka fumanoa.
4. Teko ea likaroloana tsa Magnetic ha e khone ho lemoha lisebelisoa tsa tšepe tse sa hloekang tsa austenitic le li-welds tse cheselitsoeng ka li-electrode tsa tšepe tse sa hloekang tsa austenitic, leha e le ho lemoha lisebelisoa tse seng tsa makenete tse kang koporo, aluminium, magnesium le titanium. Ho thata ho fumana li-delaminations le memeno e nang le mengoo e sa tebang holim'a metsi, e patiloeng likoti tse tebileng, le li-angles tse ka tlase ho 20 ° ka bokaholimo ba mosebetsi.

Melemo ea ho lemoha ka hare ke: 1. E khona ho lemoha lisebelisoa tse fapaneng; 2. E na le kutlo e phahameng; 3. E na le pontšo e hlakileng, ts'ebetso e bonolo le litšenyehelo tse tlaase tsa ho lemoha.
Mefokolo ea tlhahlobo ea ho kenella ke: 1. Ha e tšoanelehe bakeng sa ho hlahloba li-workpieces tse entsoeng ka lisebelisoa tse hlephileng tsa porous le li-workpieces tse nang le libaka tse thata; 2. Teko ea ho kenella ka hare e ka lemoha feela ho ajoa ha likoli ka holim'a metsi, 'me ho thata ho fumana botebo ba bofokoli, kahoo ho thata ho lemoha tlhahlobo ea Quantitative ea liphoso. Sephetho sa ho lemoha le sona se susumetsoa haholo ke opareitara.

Ho sebetsa le meeli ea tlhahlobo ea radiographic:
1. E na le kutloelo-bohloko haholoanyane ho lemoha mefokolo ea mofuta oa molumo, 'me ho bonolo ho khetholla mefokolo.
2. Radiographic negatives ho bonolo ho boloka le ho ba le traceability.
3. Bontša ka pono sebopeho le mofuta oa likoli.
4. Mefokolo Botebo ba lepato la sekoli bo ke ke ba fumanoa. Ka nako e ts'oanang, botenya ba ho lemoha bo lekanyelitsoe. Filimi e mpe e hloka ho hlatsuoa ka ho khetheha, 'me e kotsi ho' mele oa motho, 'me litšenyehelo li phahame.
