Ka mor'a hore ho phethoe ts'ebetso ea ho cheselletsa linate, ho bohlokoa ho etsa tlhahlobo e feletseng ho lekola boleng ba weld le ho netefatsa hore e finyella litekanyetso tse hlokahalang.Sengoliloeng sena se shebana le mekhoa le lits'ebetso tsa tlhahlobo tse sebelisoang hangata ho lekola bots'epehi ba weld ho tjheseletsa ha linate.
- Tlhahlobo ea Ponahalo: Tlhahlobo ea pono ke mokhoa oa pele le o bonolo oa ho lekola boleng ba weld.E kenyelletsa tlhahlobo ea pono ea sebaka sa weld bakeng sa liphoso leha e le life tse bonahalang tse kang mapetsong, li-voids, kapa motsoako o sa fellang.Mokhanni o hlahloba bokaholimo ba motsoako oa weld, a ela hloko sebopeho le boholo ba nugget, boteng ba lintho tse sa tloaelehang, le ponahalo ea kakaretso ea weld.
- Tlhahlobo ea Dimensional: Tlhahlobo ea boholo bo kenyelletsa ho lekanya litekanyo tsa bohlokoa tsa motsoako oa weld ho netefatsa hore o lumellana le mamello e boletsoeng.Sena se kenyelletsa ho lekanya bophara le bophahamo ba nugget ea weld, bophahamo ba projeke, le geometry ka kakaretso ea lenonyeletso.Litekanyo li bapisoa le litekanyo tse hlokahalang ho netefatsa sebopeho se nepahetseng sa weld.
- Teko e sa Senyeheng (NDT): Mekhoa ea tlhahlobo e sa senyeheng e ka fana ka tlhaiso-leseling ea bohlokoa mabapi le bots'epehi ba kahare ba weld ntle le ho baka tšenyo leha e le efe lenonyeletsong.Mekhoa e tloaelehileng ea NDT e sebelisoang ho tjheseletsa ha linate e kenyelletsa:
- Ultrasonic Testing (UT): Maqhubu a Ultrasonic a sebelisetsoa ho lemoha mefokolo e ka hare e kang mapetsong kapa likheo ka har'a motsoako oa weld.
- Tlhahlobo ea Radiographic (RT): Mahlaseli a X-ray kapa a gamma a sebelisetsoa ho hlahisa litšoantšo tsa weld, e leng se lumellang ho lemoha mefokolo ea ka hare kapa ho kopana ho sa fellang.
- Teko ea Magnetic Particle (MT): Likaroloana tsa Magnetic li sebelisoa holim'a weld, 'me ho lutla hofe kapa hofe ha makenete ho bakoang ke likoli ho bonoa ho sebelisoa li-sensor tsa matla a khoheli.
- Teko ea Dye Penetrant Testing (PT): Ho kenngoa ha dae ho sebelisoa ka holim'a weld, 'me liphoso leha e le life tse senyang holim'a metsi li senoloa ke dae e kenang ka har'a likoli.
- Teko ea Mechini: Teko ea mochini e kenyelletsa ho beha lenonyeletso la weld litekong tse fapaneng tsa mochini ho lekola matla le bots'epehi ba lona.Sena se ka kenyelletsa tlhahlobo e tsitsitseng, moo weld e laoloang ke matla a hulang a laoloang ho lekola ho hanyetsa ha eona ho arohana.Liteko tse ling tse joalo ka tlhahlobo ea bend kapa tlhahlobo ea boima ba 'mele le tsona li ka fana ka leseli la bohlokoa mabapi le thepa ea mochini oa weld.
Tlhahlobo ea morao-rao ea ho cheselletsa linate e bapala karolo ea bohlokoa ho netefatsa boleng le bots'epehi ba manonyeletso a weld.Ka ho sebelisa tlhahlobo ea pono, tlhahlobo ea boholo, tlhahlobo e sa senyeheng, le mekhoa ea tlhahlobo ea mochini, basebelisi ba ka tseba bofokoli kapa bofokoli bofe kapa bofe mme ba nke mehato e nepahetseng ea ho lokisa.Sena se thusa ho boloka botšepehi le ts'ebetso ea li-weld joints, ho netefatsa hore li finyella litekanyetso le litlhaloso tse hlokahalang.
