Ho etsa bonnete ba hore boleng ba ho cheselletsa linate ho bohlokoa ho netefatsa boleng ba sebopeho le ts'epahalo ea manonyeletso a cheselitsoeng. Ho sebelisoa mekhoa e fapaneng ea tlhahlobo ho lekola boleng ba weld, ho bona mefokolo, le ho netefatsa ho lateloa ha maemo a indasteri. Sengoliloeng sena se hlahloba mekhoa le lits'ebetso tse fapaneng tse sebelisoang ho lekola litšepe tsa linate le ho lekola bots'epehi ba weld.
- Tlhahlobo ea Pono: Tlhahlobo ea pono ke mokhoa oa bohlokoahali oa ho lekola boleng ba weld. E akarelletsa ho hlahloba lenonyeletso le cheselitsoeng ka mahlo ho fumana mefokolo leha e le efe e bonahalang, e kang ho kopanngoa ho sa fellang, porosity, mapetsong, kapa boholo bo sa lokelang. Bahlahlobi ba nang le litsebo ba hlahloba ponahalo ea kakaretso ea weld mme ba e bapisa khahlanong le mekhoa e amohelehang ea ho amohela ho fumana hore na weld e finyella litekanyetso tse hlokahalang.
- Tekanyo ea Dimensional: Litekanyo tse nepahetseng tsa boholo lia hlokahala ho netefatsa hore motsoako oa weld o lumellana le litlhaloso tsa moralo. Ba sebelisa lisebelisoa tse khethehileng, bahlahlobi ba lekanya litekanyo tse fapaneng tsa weld, joalo ka boholo ba weld, sekontiri se phahameng le bolelele ba weld. Phapang efe kapa efe ho tloha ho litekanyo tse boletsoeng e ka bonts'a mathata a ka bang teng a boleng kapa a sebetsa liphapano tse ka amang ts'ebetso ea weld.
- Teko e Senyehileng: Mekhoa ea liteko e senyang e kenyelletsa ho tlosa sampole kapa karolo ea motsoako oa weld bakeng sa tlhahlobo le tlhahlobo. Liteko tse tloaelehileng tse senyang bakeng sa ho cheselletsa linate li kenyelletsa tlhahlobo ea matla, tlhahlobo ea bend, le tlhahlobo ea microstructural. Liteko tsena li fana ka leseli mabapi le thepa ea mochini oa weld, ho kenyeletsoa matla, ductility, le bots'epehi ba sebopeho.
- Teko e sa Senyeheng (NDT): Mekhoa ea tlhahlobo e sa senyeheng e sebelisoa ho lekola bots'epehi ba weld ntle le ho baka tšenyo leha e le efe. Mekhoa ea NDT e atisang ho sebelisoa bakeng sa tlhahlobo ea li-welding ea linate e kenyelletsa tlhahlobo ea ultrasonic, tlhahlobo ea hona joale ea eddy, le tlhahlobo ea radiographic. Mekhoa ena e ka lemoha mefokolo ea ka hare, e kang mapetsong, porosity, kapa fusion e sa fellang, ho netefatsa hore weld e finyella litekanyetso tse hlokahalang tsa boleng.
- Ultrasonic Time-of-Flight Diffraction (TOFD): TOFD ke mokhoa o khethehileng oa tlhahlobo ea ultrasonic o fanang ka mokhoa o nepahetseng oa ho lemoha le ho etsa boholo. E sebelisa maqhubu a molumo oa maqhubu a phahameng ho bona le ho bonts'a mefokolo ea kahare ho weld, joalo ka khaello ea fusion, cracks, kapa voids. TOFD e fana ka liphetho tse tšepahalang 'me e ka sebelisoa bakeng sa mekhoa ea tlhahlobo ea matsoho le ea boiketsetso.
Ho hlahloba boleng ba ho tjheseletsa ha linate ho bohlokoa ho etsa bonnete ba ho ts'epahala le ho ts'epahala ha weld. Tlhahlobo e bonoang, tekanyo ea boholo, liteko tse senyang, tlhahlobo e sa senyeheng, le mekhoa e ikhethileng e kang TOFD ke lisebelisoa tsa bohlokoa tsa ho lekola boleng ba weld le ho bona mefokolo. Ka ho sebelisa mekhoa ena ea ho hlahloba, bahlahisi le bahlahlobi ba ka netefatsa hore li-welds li finyella litekanyetso le litlhaloso tse hlokahalang, ho netefatsa boleng ba kakaretso le ts'ebetso ea ho cheselletsa linate lits'ebetsong tse fapaneng.
