Teko e sa senyeheng ke ts'ebeliso ea lisebelisoa tsa acoustic, optical, makenete le motlakase, ntle le ho senya kapa ho ama ts'ebeliso ea ntho e tlas'a motheo oa ts'ebetso ea ntho e lokelang ho hlahlojoa, ho bona boteng ba bofokoli kapa inhomogeneities nthong eo. ho hlahlojoa, ho fana ka boholo ba bofokoli, sebaka sa mefokolo, mofuta oa palo ea tlhahisoleseling joalo-joalo, ebe ho khethoa boemo ba tekheniki ba ntho e tla hlahlojoa (mohlala, e tšoanelehang kapa e sa tšoaneleheng, bophelo bo setseng. joalo-joalo) mekhoa eohle ea tekheniki ea nako e akaretsang.
Mekhoa e tloaelehileng ea ho hlahloba e sa senyeheng: Tlhahlobo ea Ultrasonic (UT), Tlhahlobo ea Magnetic Particle (MT), Tlhahlobo ea Liquid Penetration (PT) le Tlhahlobo ea X-ray (RT).
Tlhahlobo ea Ultrasonic
UT (Teko ea Ultrasonic) ke e 'ngoe ea mekhoa ea tlhahlobo e sa senyeheng indastering. Maqhubu a Ultrasonic ka har'a ntho e nang le bofokoli, karolo ea leqhubu la molumo e tla bonts'oa, mochini o fetisang le moamoheli a ka sekaseka leqhubu le bonts'itsoeng, e ka ba tekanyo e nepahetseng ea liphoso. 'Me e ka bonts'a sebaka le boholo ba mefokolo ea ka hare, fumana hore na thepa e boima hakae.
Melemo ea tlhahlobo ea Ultrasonic:
1, bokhoni ba ho kenella bo boholo, ka mohlala, ka tšepe ka botebo ba ho lemoha bo fihlang ho 1 metres kapa ho feta;.
2, bakeng sa mefokolo ea mofuta oa sefofane joalo ka mapetsong, li-interlayers, joalo-joalo, ho lemoha maikutlo a phahameng, 'me e khona ho tseba botebo le boholo bo lekanyelitsoeng ba liphoso;
3, lisebelisoa tse bobebe, ts'ebetso e bolokehileng, e bonolo ho elelloa tlhahlobo e ikemetseng.
Mefokolo:
Ha ho bonolo ho hlahloba sebopeho se rarahaneng sa workpiece, ho hloka tekanyo e itseng ea boreleli ba holim'a e hlahlojoa, 'me moemeli oa ho kopanya o hlokeha ho tlatsa lekhalo pakeng tsa probe le sebaka se hlahlobiloeng ho etsa bonnete ba hore ho na le khokahanyo e lekaneng ea acoustic.
Tlhahlobo ea Magnetic Particle
Pele ho tsohle, a re utloisise molao-motheo oa tlhahlobo ea likaroloana tsa makenete. Kamora matla a matla a lisebelisoa tsa ferromagnetic le li-workpieces, ka lebaka la ho ba teng ha li-discontinuities, mehala ea matla a khoheli holim'a sebaka sa mosebetsi le haufi le sebaka sa ho sotha ha lehae, 'me e hlahisa sebaka sa ho lutla, adsorption ea phofo ea makenete e sebelisoang holimo. ea workpiece, ho etsa mohlala o bonahalang oa khoheli ka leseli le loketseng, ka hona o bonts'a sebaka, sebopeho le boholo ba ho se tsoele pele.
Ho sebetsa le mefokolo ea tlhahlobo ea likaroloana tsa makenete ke:
1, tšibollo ea bofokoli ba matla a khoheli e loketse ho bona li-discontinuity holim'a lisebelisoa tsa ferromagnetic le haufi le bokaholimo ka boholo bo nyane haholo le likheo tse moqotetsane haholo tseo ho leng thata ho li bona.
2, tlhahlobo ea likaroloana tsa makenete e ka ba maemo a fapaneng a ho fumanoa ha likarolo, empa hape le mefuta e fapaneng ea likarolo tse lokelang ho bonoa.
3, e ka fumana mapetsong, li-inclusions, moriri oa moriri, matheba a masoeu, ho phutha, ho arola ho batang le liphoso tse hlephileng le tse ling.
4, tlhahlobo ea likaroloana tsa makenete ha e khone ho bona lisebelisoa tsa tšepe tse sa hloekang tsa austenitic le li-welds tse cheselitsoeng ka li-electrode tsa tšepe tse sa hloekang tsa austenitic, 'me ha li khone ho bona koporo, aluminium, magnesium, titanium le lisebelisoa tse ling tseo e seng tsa makenete. Bakeng sa holim 'a mengoapo e sa tebang, patoa masoba tebileng le le workpiece holim'a angle ka tlaase ho 20 ° delamination le phutha ho thata ho fumana.
Ho lemoha ho kenella ha metsi
Molao-motheo oa motheo oa ho lemoha ho kenella ha metsi, karolo e ka holim'a karolo e koahetsoe ka dae ea fluorescent kapa mebala ea mebala, ka nako e itseng tlas'a ketso ea capillary, mokelikeli o phunyeletsang o ka kenella ka har'a mefokolo ea ho bula holimo; ka mor'a ho tlosa mokelikeli o feteletseng o phunyeletsang holim'a karolo, ebe o koahetsoe ke moqapi holim'a karolo.
Ka mokhoa o ts'oanang, tlas'a ts'ebetso ea capillary, moqapi o tla hohela liphoso ho bolokoeng ha permeate, ho khutlela ho moqapi, mohloling o itseng oa leseli (leseli la ultraviolet kapa leseli le lesoeu), mefokolo e hlahang mekhoeng ea permeate e bontšoa, ( fluorescent e bosehla bo botala kapa bofubelu bo khanyang), e le ho lemoha mefokolo ea sebōpeho le ho ajoa ha naha.
Melemo ea ho lemoha ho kenella ke:
1, e khona ho bona lisebelisoa tse fapaneng;
2, e na le kutlo e phahameng;
3, ponts'o e bonolo, e bonolo ho sebetsa, litšenyehelo tse tlase tsa ho lemoha.
Mme mathata a tlhahlobo ea ho kenella ke:
1, ha e tšoanelehe bakeng sa tlhahlobo ea lisebelisoa tse hlephileng tse entsoeng ka li-workpieces le li-workpieces tse ka holimo;
2, tlhahlobo ea ho kenella e ka bona feela ho ajoa ha likoli holimo, ho thata ho tseba botebo ba bofokoli, ka hona ho thata ho etsa tlhahlobo ea bofokoli bo bongata. Liphetho tsa ho sibolloa le tsona li angoa ke opareitara.
Thepa ea welding ea Xinfa e na le litšobotsi tsa boleng bo holimo le theko e tlase. Ho fumana lintlha, ka kopo etela:Baetsi ba Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Tlhahlobo ea X-ray
Ea ho qetela, ho lemoha mahlaseli, hobane mahlaseli a X-ray ka ntho e khantšitsoeng e tla ba le tahlehelo, botenya bo fapaneng ba lintho tse fapaneng ka tekanyo ea ho monya ha bona bo fapane, 'me bobe bo behiloe ka lehlakoreng le leng la ntho e khantšitsoeng, hobane matla a mahlaseli. li fapane 'me li hlahisa setšoantšo se lumellanang, bahlahlobi ba lifilimi ba ka thehoa setšoantšong ho fumana hore na ho na le mefokolo ka har'a ntho hammoho le mofuta oa liphoso.
Ho sebetsa le mefokolo ea ho lemoha mahlaseli:
1, e hlokolosi haholoanyane ho bona mefokolo ea volumetric, ho bonolo ho khetholla liphoso.
2, ho bonolo ho boloka mahlaseli a kotsi, ho na le traceability.
3, pono ea sebopeho le mofuta oa liphoso.
4, bofokoli bo ke ke ba fumana botebo bo patiloeng ba bofokoli, ha ho fumanoa ha botenya bo fokolang, botenya bo hloka ho romelloa ka ho khetheha ho hlatsoa, 'me' mele oa motho o na le kotsi e itseng, litšenyehelo li phahame.
Ka bokhutšoane, ultrasonic, X-ray ho lemoha liphoso ho loketse bakeng sa ho lemoha mefokolo ea ka hare; moo ultrasonic bakeng sa ho feta 5mm, le sebōpeho sa likarolo tse tloaelehileng, X-ray e ke ke ea fumana botebo bo patiloeng ba likoli, mahlaseli. Magnetic particle le pholiso ea ho kenella li loketse ho bona mefokolo holim'a likarolo; har'a tsona, ho lemoha bofokoli ba matla a khoheli ho lekanyelitsoe ho lemoha lisebelisoa tsa makenete, 'me ho lemoha phoso ea ho kenella ho lekanyelitsoe ho lemoha mefokolo e bulehileng holim'a metsi.
