Ho netefatsa matla a tjheseletsa a metjhini e tjheseletsang letheba ke ntho ya bohlokwa ho netefatsa ho tshepeha le ho tshwarella ha manonyeletso a tjheseditsweng. Sehloohong sena, re tla hlahloba mekhoa ea ho lekola matla a tjheseletsa ea mochini oa tjheseletsa oa linate. Ka ho etsa liteko tse nepahetseng, bahlahisi ba ka netefatsa boleng le botšepehi ba li-welds, ba li nolofalletsa ho finyella litekanyetso le litlhaloso tse hlokahalang.
- Teko ea Teko: Teko ea tensile ke mokhoa o sebelisoang haholo ho lekola matla a ho cheselletsa li-welds tsa linate. Teko ena e kenyelletsa ho sebelisa mojaro oa axial ho lenonyeletso le cheselitsoeng ho fihlela le fihla ho hloleha. Matla a mangata a mamelloang ke weld a bontša matla a eona a thata. Teko ea tensile e ka etsoa ho sebelisoa lisebelisoa tse khethehileng tsa tlhahlobo, joalo ka mochini oa tlhahlobo ea bokahohleng, o lekanyang moroalo le litšobotsi tsa deformation tsa weld.
- Teko ea Shear: Teko ea ho kuta ke mokhoa o mong o tloaelehileng oa ho lekola matla a ho cheselletsa li-welds tsa linate. Tekong ena, matla a ho kuta a sebelisoa ka mokhoa o ts'oanang le sehokelo sa weld ho fumana hore na moroalo o mongata o ka mamella eng pele o hloleha. Teko ea ho kuta e loketse haholo lits'ebetso moo li-weld li nang le khatello ea maikutlo haholo, joalo ka likhokahano tsa li-fasteners.
- Teko ea Peel: Teko ea lekhapetla e sebelisoa haholo ho lekola matla a ho tjheseletsa a manonyeletso a kobehileng, joalo ka a theoang ka ho cheselletsa linate holim'a lakane. Teko ena e kenyelletsa ho sebelisa moroalo o thata o pota-potileng sefofane sa lenonyeletso, ho etsa hore weld e arohane. Matla a hlokahalang ho qalisa le ho jala lekhapetla le bontša matla a cheseletso. Teko ea peel e ka etsoa ho sebelisoa lisebelisoa tse khethehileng, joalo ka sehlahlo sa peel, se lekanyang ho hanyetsa lekhapetla la weld.
- Tlhahlobo ea Pono: Tlhahlobo ea pono e bapala karolo ea bohlokoa ho lekola boleng le bots'epehi ba li-welds tsa linate. Bahlahlobi ba sheba litšepe ka mahlo bakeng sa mefokolo e fapaneng, joalo ka ho kopanngoa ho sa fellang, porosity, mapetsong, kapa spatter e feteletseng. Tlhahlobo ea pono e lokela ho etsoa ho latela litekanyetso tse behiloeng le litlhaloso ho netefatsa tlhahlobo e tsitsitseng ea matla a ho cheselletsa.
- Teko e sa Senyeheng (NDT): Mekhoa ea tlhahlobo e sa senyeheng, joalo ka tlhahlobo ea ultrasonic kapa tlhahlobo ea radiographic, le eona e ka sebelisoa ho lekola matla a ho cheselletsa li-welds tsa linate. Mekhoa ena e sebelisa mahlale a tsoetseng pele ho bona mefokolo kapa ho se lumellane ka hare ho weld, ho fana ka tlhahisoleseling ea bohlokoa mabapi le boleng ba weld ntle le ho baka tšenyo.
Ho lekola matla a ho cheselletsa mochini oa ho cheselletsa linate ho bohlokoa bakeng sa ho netefatsa bots'epehi le ts'epahalo ea manonyeletso a cheselitsoeng. Ka ho sebelisa mekhoa e joalo ka tlhahlobo ea matla, tlhahlobo ea ho kuta, tlhahlobo ea peel, tlhahlobo ea pono le tlhahlobo e sa senyeheng, bahlahisi ba ka lekola matla le boleng ba li-welds. Sena se ba lumella ho kopana le litekanyetso le litlhaloso tse hlokahalang, ho fana ka kholiseho ts'ebetsong ea lisebelisoa tsa ho cheselletsa linate.
