Ho etsa tlhahlobo ea boleng ba post-weld ke mohato oa bohlokoa mochining oa ho cheselletsa butt ho netefatsa bots'epehi le ts'epahalo ea li-welds.Ho utloisisa ts'ebetso ea tlhahlobo ea boleng ba post-weld ho bohlokoa bakeng sa li-welders le litsebi tsa indasteri ea welding ho tseba le ho lokisa liphoso kapa litaba tse amanang le ts'ebetso ea welding.Sengoliloeng sena se hlahloba mehato e amehang tlhahlobong ea boleng ba post-weld bakeng sa mechini ea ho tjheseletsa butt, ho totobatsa bohlokoa ba ts'ebetso ena ho fihlela li-welds tsa boleng bo holimo.
- Tlhahlobo ea Pono: Tlhahlobo ea pono ke mohato oa pele oa tlhahlobo ea boleng ba morao-rao.Li-welders li hlahloba ka hloko sefaha se cheselletsang, ho sheba mefokolo leha e le efe e bonahalang e kang mapetsong, porosity, motsoako o sa fellang, kapa ho se tloaelehe ha bokaholimo.Lisebelisoa tse nepahetseng tsa ho bonesa le ho hlahloba li thusa ho tseba mefokolo e ka bang teng.
- Litekanyo tsa Dimensional: Litekanyo tsa litekanyo tse mahlonoko tsa weld li nkuoa ho netefatsa hore li lumellana le litlhaloso tsa welding le moralo o kopaneng.Mohato ona o etsa bonnete ba hore weld e kopana le mamello e hlokahalang le litekanyetso tsa geometri.
- Teko e sa Senyeheng (NDT): Mekhoa ea tlhahlobo e sa senyeheng, joalo ka tlhahlobo ea ultrasonic, tlhahlobo ea radiographic, le tlhahlobo ea dae e kenang ka har'a dae, e sebelisoa ho bona mefokolo le li-discontinuities tse ka 'nang tsa se ke tsa bonahala ka tlhahlobo ea pono feela.NDT e bohlokoa ho hloaeang bofokoli bo ka senyang bots'epehi ba sebopeho sa weld.
- Teko ea Mechini: Teko ea mochini e kenyelletsa ho beha li-welds meroalo e itseng kapa khatello ea maikutlo ho lekola thepa ea bona ea mochini.Teko ea ho teneha, tlhahlobo ea boima ba 'mele le tlhahlobo ea phello ke mekhoa e tloaelehileng e sebelisoang ho lekola matla, ho tiea le ho tiea ha chese.
- Tlhahlobo ea Microscopic: Tlhahlobo ea Microscopic e lumella tlhahlobo e haufi ea microstructure ea weld.Tlhahlobo ena e thusa ho tseba lintho tse ka 'nang tsa e-ba teng tsa sebopeho sa lijo-thollo, karohano le liphetoho tse ka amang thepa ea mochini oa weld.
- Kalafo ea Mocheso oa Post-Weld (PWHT): Bakeng sa lits'ebetso tse ling tsa bohlokoa, kalafo ea mocheso ka mor'a weld e ka etsoa kamora ts'ebetso ea welding.PWHT e thusa ho imolla khatello ea maikutlo e setseng le ho ntlafatsa thepa ea mochini oa weld, e matlafatsa botšepehi ba eona ka kakaretso.
- Litokomane tse bonoang: Litokomane tse nepahetseng le tse qaqileng tsa liphuputso tsa tlhahlobo li bohlokoa bakeng sa ho boloka lirekoto le tšebeliso ea nako e tlang.Lifoto, lirekoto tsa litekanyo, le liphetho tsa liteko li ngotsoe ho boloka nalane ea tlhahlobo e felletseng.
- Netefatso ea Tumellano: Tlhahlobo ea boleng ba morao-rao e netefatsa hore li-welds li kopana le maemo a amehang a indasteri, likhoutu le litlhaloso tsa bareki.Netefatso ea tumellano e bohlokoa bakeng sa ho netefatsa boleng le polokeho ea likarolo tse cheselitsoeng.
Qetellong, ho etsa tlhahlobo ea boleng ba post-weld ke karolo ea bohlokoa ea mechini ea welding ea butt ho netefatsa botšepehi le ts'epo.Tlhahlobo e bonoang, litekanyo tsa boholo, tlhahlobo e sa senyeheng, tlhahlobo ea mochini, tlhahlobo ea microscopic, kalafo ea mocheso ka mor'a weld, le netefatso ea ho latela melao ke mehato ea bohlokoa ts'ebetsong ena.Ka ho khomarela mekhoa e matla ea tlhahlobo ea boleng, li-welders le litsebi li ka tseba le ho rarolla mathata leha e le afe kapa mathata a ts'ebetsong ea ho cheselletsa, e leng se lebisang ho li-welds tsa boleng bo phahameng tse finyellang litekanyetso tsa indasteri le litlhoko tsa bareki.Bohlokoa ba tlhahlobo ea boleng ba morao-rao bo totobatsa karolo ea eona ho fihlelleng bokhabane ba weld le ho kenya letsoho ntlafatsong ea theknoloji ea ho cheselletsa lits'ebetsong tse fapaneng tsa indasteri.
