20.500.12556/RUL-103115 Oblikovno obločno navarjanje nerjavnega jekla Wire arc additive manufacturing of stainless steel Obločno navarjanje z dodajanjem žice je postopek z mnogimi prednostmi v primerjavi s konvencionalnimi metodami izdelovanja: Hitra izdelava prototipov, popravilo že obstoječih elementov in dober izkoristek materiala. Zaradi teh lastnosti je uporaba postopka predvsem zanimiva na področjih, kjer se zahteva uporaba dražjih kovin. V nalogi so predstavljene teoretične osnove MIG/MAG varjenja in obločnega navarjanja z dodajanjem žice. Raziskovali smo vpliv različnih parametrov pulznega obločnega navarjanja z žico nerjavnega jekla na izkoristek in geometrijo izdelkov. Ugotovili smo, da je uporaba metode ob primerni izbiri parametrov glede na zahteve primerna za izdelavo izdelka in to tudi preizkusili z izdelavo izdelka z bolj kompleksno geometrijo. Wire Arc Additive Manufacturing is a process with many benefits in comparison to conventional manufacturing methods: quick prototyping, repair of existing products and high material efficiency. Due to these properties, the use of wire arc additive manufacturing is especially interesting in areas, which require use of expensive metals. This thesis explains the theoretical basics of MIG/MAG welding and wire arc additive manufacturing. We have investigated the effect of pulse welding parameters on the efficiency and geometry of stainless steel samples. We came to the conclusion, that the use of this method is possible if appropriate welding parameters are chosen in regard to the requirements. We tested this by producing a final product with relatively complex geometry. obločno navarjanje z žico varjenje MIG/MAG nerjavno jeklo pulzno varjenje aditivna proizvodnja Wire Arc Additive Manufacturing MIG/MAG welding stainless steel pulse welding additive manufacturing true false false [M.
