Analiza sestave in geometrije delcev prahu v laboratoriju za varjenje
Mirza Imširović, Borut Kosec
Diplomsko delo
Oznake: delci prahu;dimni plini;ročno obločno varjenje;kakovost zraka;geometrija;sestava;
Cilj diplomske naloge je bila analiza in klasifikacija delcev prahu, ki se sproščajo v dimnih plinih pri ročnem obločnem varjenju. Testne meritve so bili izvedene z testno napravo Zambelli EGO TT, ki je namenjena kontroli kakovosti zraka. Postopki varjenja so potekali pri okoliški temperaturi 26 °C ...

Vrednotenje emisij delcev prahu pri procesih varjenja in rezanja
Mirza Imširović, Borut Kosec, Damjan Klobčar
Magistrsko delo
Oznake: delci prahu;dimni plini;varjenje;kakovost zraka;geometrija;sestava;
Pri procesih varjenja in rezanja se sproščajo različni dimni plini, ki imajo v veliki meri vpliv na zdravje operativnih oseb. V okviru magistrskega dela je bilo izvedeno vzorčenje in analiza delcev prahu, ki se sproščajo pri različnih postopkih varjenja. Postopki varjenja so potekali po TIG in MIG p ...

Enhancing the mechanical properties ofdirected [!] energy deposition arc (DED-Arc) via processing innovations
Damjan Klobčar, Uroš Trdan, Mirza Imširović, Drago Bračun, Mohammad Reza Ghavi, Tomaž Vuherer, Marek Polanski, Aleksija Ðurić, Matija Bušić, Miodrag Milčić
Objavljeni znanstveni prispevek na konferenci (vabljeno predavanje)
Oznake: directed energy deposition;DED;wire and arc additive manufacturing;WAAM;in-situ vibrations;heat treatment;porosity reduction;residual stress;grain refinement;surface waviness;mechanical properties;fracture toughness;computed tomography scan;CT;
Directed Energy Deposition (DED) processes offer the advantage of producing larger parts with higher deposition rates compared to Powder Bed Fusion (PBF) additive manufacturing (AM). However, DED typically results in simpler geometries and lower resolution. When using Wire and Arc-based DED, even ...
