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 likhaello 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 liphoso tse ka hare, tse kang 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, e kang mapetso, li-inclusions, kapa fusion e sa fellang, ka ho nka mahlaseli a fetisoang filiming ea radiographic kapa mochine oa 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.
