Khatello ea tjheseletsa ea sebaka sa mahareng sa maqhubu ke khatello e bakoang ke ho cheselletsa likarolo tse cheselitsoeng. Motso oa ho tjheseletsa khatello ea kelello le deformation ke sebaka sa mocheso o sa ts'oaneng le deformation ea polasetiki ea lehae le sebopeho se fapaneng sa molumo se bakoang ke sona.
E bua ka khatello ea maikutlo e hlahisoang ho weldment. Ke eona sesosa se ka sehloohong sa deformation ea sebopeho le sebopeho sa crack. Khatello ea welding e ka aroloa ka khatello ea mocheso ea nakoana le khatello e setseng ea welding. Khatello ea maikutlo: e bua ka ketsahalo ea hore khatello ea kelello sebakeng se itseng nthong e fokotsehile ka lebaka la ho lokolloa ha matla; Ho lokolloa ha matla, ho ba hantle.
Ha mocheso o sa lekaneng oa mocheso o bakoang ke welding o e-s'o nyamele, khatello ea kelello le deformation ho weldment li bitsoa "transient welding stress" le deformation. Khatello ea maikutlo le deformation ka mor'a hore mocheso oa mocheso oa welding o nyamele o bitsoa residual welding stress and deformation.
Tlas'a boemo ba ho se na matla a ka ntle, khatello ea welding e leka-lekane ka hare ho weldment. The tjheseletsa khatello ea kelello le deformation tla ama mosebetsi le ponahalo ea weldment tlas'a maemo a itseng.
