Ho netefatsa boleng ba li-welds tsa linate ho bohlokoa bakeng sa ho fihlela manonyeletso a ts'epahalang le a sebopeho se setle mochining oa ho cheselletsa linate. Sengoliloeng sena se fana ka mekhoa e fapaneng ea tlhahlobo e ka sebelisoang ho lekola boleng ba li-welds tsa linate. Ka ho sebelisa mekhoa ena, bahlahisi ba ka tseba mefokolo efe kapa efe e ka bang teng ho li-welds mme ba nka mehato e nepahetseng ho boloka litekanyetso tse phahameng tsa welding.
- Tlhahlobo ea Pono: Tlhahlobo ea pono ke mokhoa oa bohlokoa oa ho lekola ponahalo le boemo ba bokaholimo ba li-welds tsa linate. Bahlahlobisisi ba hlahloba sebaka seo ho chesehelang ho sona ho bona matšoao a mapetsong, a porosity, a sa fellang, kapa likoli leha e le life tse bonahalang. Mokhoa ona o hloka basebetsi ba nang le litsebo ba koetliselitsoeng ho lemoha mefokolo ea ho cheselletsa le ho kheloha ho tsoa ho profil e batloang ea weld.
- Teko ea Dye Penetrant: Teko ea ho kenella ka dae ke mokhoa o sa senyeheng oa tlhahlobo o sebelisetsoang ho bona bofokoli bo robehileng holim'a li-welds tsa linate. Tharollo e phunyeletsang e sebelisoa holim'a weld, 'me ka mor'a nako e itseng ea ho lula, ho kenella ho feteletseng ho tlosoa. Ka mor'a moo ho sebelisoa moqapi, e leng se hulelang motho leha e le ofe ea kenang ka har'a sekoli, a etsa hore a bonahale. Mokhoa ona o ka khetholla mapetsong, porosity, le likoli tse ling tse ka senyang botšepehi ba weld.
- Teko ea Radiographic: Teko ea radiographic, eo hangata e tsejoang ka hore ke X-ray kapa tlhahlobo ea radiographic, ke mokhoa o sebelisoang haholo ho lekola bots'epehi ba kahare ba linate. Mahlaseli a X-ray kapa a gamma-ray a fetisoa ka har'a weld, 'me setšoantšo se hlahisoang se senola ho se tsoele pele ka hare ho kang li-voids, inclusions, kapa khaello ea fusion. Mokhoa ona o fana ka tlhahlobo e felletseng ea sebopeho sa kahare sa weld mme o sebetsa ka ho khetheha bakeng sa ho lemoha mefokolo e patiloeng.
- Tlhahlobo ea Ultrasonic: Teko ea Ultrasonic e sebelisa maqhubu a molumo o phahameng haholo ho hlahloba li-welds tsa linate bakeng sa mefokolo ea kahare. Transducer e behoa holim'a weld surface, e hlahisang maqhubu a ultrasonic a jalang ka har'a weld. Liphetoho leha e le life, tse kang voids, cracks, kapa khaello ea fusion, li tla baka maikutlo kapa liphetoho maqhubu a ultrasonic, a ka fumanoang le ho hlahlojoa. Tlhahlobo ea Ultrasonic e fana ka tlhaiso-leseling ea bohlokoa mabapi le sebopeho sa kahare sa weld mme e khona ho bona mefokolo e kanna ea se bonahale ka mahlo.
- Teko ea Tensile le Bend: Teko ea ho tiea le ho kobeha e kenyelletsa ho beha mehlala ea liteko e ntšitsoeng ho li-welds tsa linate ho ea ho matla a mochini. Teko ea tsitsipano e lekanya matla a weld ka ho sebelisa matla a ho hula ho fihlela lenonyeletso la weld le robeha, ha tlhahlobo ea bend e lekola ductility ea weld ka ho koba mohlala ho lekola khanyetso ea eona ho petsoha kapa deformation. Liteko tsena li fana ka lintlha tse ngata mabapi le thepa ea mochini oa weld, joalo ka matla a thata, bolelele, le ho hanyetsa tšusumetso.
Boleng ba li-welds tsa linate mochining oa ho cheselletsa linate bo ka hlahlojoa ka katleho ho sebelisoa mekhoa e fapaneng ea tlhahlobo. Tlhahlobo ea pono, tlhahlobo ea dae e kenang, tlhahlobo ea radiographic, tlhahlobo ea ultrasonic, le mekhoa ea tlhahlobo ea mochini e fana ka tlhaiso-leseling ea bohlokoa mabapi le boemo ba bokaholimo ba weld, botšepehi ba kahare le thepa ea mochini. Ka ho kenya ts'ebetsong mekhoa ena ea tlhahlobo, bahlahisi ba ka etsa bonnete ba hore li-welds tsa linate li finyella litekanyetso tse boletsoeng tsa boleng le ho kenya letsoho tlhahisong ea likopano tse matla le tse ka tšeptjoang.
