Matematično modeliranje toplotnih in strukturnih procesov pri TIG varjenju feritnega nerjavnega jekla = [Mathematical modelling of thermal and structural processes in welding of ferritic stainless steel] : doktorsko deloMarkelj, Franc, 1944-ǂV ǂpričujočem delu je raziskano feritno nerjavno jeklo AISI 430 debelin 0,5 mm, 1,00 mm in 1,5 mm. Po TIG postopku brez dodajnega materiala so bili varjeni 4 zvarni spoji: sočelni, prekrovni in ... vogelni ter spoj T. Določeni so bili optimalni varilni parametri: jakost varilnega toka, varilna hitrost, debelina elektrode, dolžina varilnega obloka in varilna toplota. Za sočelni spoj pločevine AISI 430 debeline 1 mm so bile s pomočjo termokamere in termoelementov določene temperature v zvaru in v toplotno vplivanem področju, raziskana je bila mikro- in makrostruktura zvarnega spoja ter izvedeni korozijski in mehanski testi. Za pločevino debeline 1 mm je bil izdelan matematični model za temperaturni gredient in za pričakovano širino vmesnega področja v sredini zvara.Type of material - dissertationPublication and manufacture - Ljubljana : [F.
