Ka mor'a ts'ebetso ea ho cheselletsa ho cheselletsa linate, ho bohlokoa ho etsa tlhahlobo e phethahetseng ho lekola boleng le bots'epehi ba lenonyeletso la weld. Sengoliloeng sena se fana ka kakaretso ea mekhoa e fapaneng ea liteko e sebelisoang bakeng sa tlhahlobo ea morao-rao ea ho cheselletsa linate, e totobatsang bohlokoa ba tsona ho lekola ts'ebetso ea weld.
- Tlhahlobo ea Pono: Tlhahlobo ea pono ke mokhoa oa pele le oa mantlha oa ho lekola boleng ba li-welds tsa linate. E kenyelletsa tlhahlobo ea pono ea lenonyeletso la weld bakeng sa liphoso tsa bokaholimo, joalo ka mapetsong, porosity, spatter, kapa motsoako o sa fellang. Tlhahlobo ea pono e thusa ho tseba mefokolo leha e le efe e bonahalang e ka amang matla le ho tšepahala ha weld.
- Tlhahlobo ea Macroscopic: Tlhahlobo ea macroscopic e kenyelletsa ho shebella lenonyeletso la weld tlas'a ho holisoa kapa ka leihlo le hlobotseng ho hlahloba sebopeho sa lona ka kakaretso le geometry. E lumella ho lemoha mefokolo ea weld, ho kenyelletsa le flash e feteletseng, ho se lumellane, ho thehoa ha nugget e sa lokelang, kapa ho kena ho sa lekaneng. Tlhahlobo ea macroscopic e fana ka tlhaiso-leseling ea bohlokoa mabapi le boleng ba kakaretso le ho latela lintlha tsa welding.
- Tlhahlobo ea Microscopic: Ho etsoa tlhahlobo ea microscopic ho lekola sebopeho sa sebaka sa weld. E kenyelletsa ho lokisoa ha disampole tsa metallographic, tse ntan'o hlahlojoa ka microscope. Mokhoa ona o thusa ho tseba boteng ba bofokoli ba microstructural, joalo ka li-anomalies tsa moeli oa lijo-thollo, mekhahlelo ea intermetallic, kapa karohano ea tšepe ea weld. Tlhahlobo ea Microscopic e fana ka leseli mabapi le litšobotsi tsa tšepe tsa weld le tšusumetso e ka bang teng ho thepa ea mochini.
- Mekhoa ea Teko e sa Senyeheng (NDT): a. Ultrasonic Testing (UT): UT e sebelisa maqhubu a molumo a phahameng-frequency ho hlahloba motsoako oa weld bakeng sa bokooa ba ka hare, joalo ka voids, porosity, kapa ho hloka fusion. Ke mokhoa o sebelisoang haholo oa NDT o fanang ka leseli le felletseng mabapi le sebopeho sa kahare sa weld ntle le ho senya sampole. b. Tlhahlobo ea Radiographic (RT): RT e kenyelletsa tšebeliso ea mahlaseli a X-ray kapa mahlaseli a gamma ho hlahloba lenonyeletso la weld bakeng sa liphoso tse ka hare. E khona ho lemoha mefokolo, joalo ka mapetso, li-inclusions, kapa fusion e sa fellang, ka ho nka mahlaseli a fetisoang filiming ea radiographic kapa detector ea digital. c. Teko ea Magnetic Particle (MPT): MPT e sebelisoa ho bona mefokolo e kaholimo le e haufi le bokaholimo, joalo ka mapetsong kapa ho khaotsa ho sebetsa, ho sebelisoa matla a khoheli le likaroloana tsa makenete. Mokhoa ona o sebetsa haholo bakeng sa lisebelisoa tsa ferromagnetic.
- Teko ea Mechini: Teko ea mochini e etsoa ho lekola thepa ea mochini ea li-welds tsa linate. Liteko tse tloahelehileng li kenyelletsa tlhahlobo ea khatello ea maikutlo, tlhahlobo ea boima ba 'mele, le tlhahlobo ea mokhathala. Liteko tsena li lekola matla a weld, ductility, hardness, le mokhathala o hanang, ho fana ka leseli la bohlokoa mabapi le ts'ebetso ea eona tlasa maemo a fapaneng a ho kenya.
Tlhahlobo ea post-weld e bohlokoa ho tjheseletsa ha linate ho netefatsa boleng le ts'epahalo ea lenonyeletso la weld. Ka ho sebelisa tlhahlobo ea pono, tlhahlobo ea macroscopic le microscopic, mekhoa ea tlhahlobo e sa senyeheng, le tlhahlobo ea mochini, basebelisi ba ka lekola bots'epehi ba weld ka botlalo, ba bona liphoso le ho lekola thepa ea eona ea mochini. Mekhoa ena ea ho hlahloba e thusa ho etsa bonnete ba hore li-welds tsa linate li finyella litekanyetso le litlhaloso tse hlokahalang, tse tlatsetsang likopanong tse sireletsehileng le tse tšoarellang.
