Abstract

U teoretskom dijelu rada ukratko je opisan MAG postupak zavarivanja, parametri MAG zavarivanja i konvencionalni načini prijenosa metala u električnom luku. Poseban naglasak stavljen je na moderne, inverterske izvore struje za zavarivanje, mogućnosti podešavanja parametara te specifične funkcije koje posjeduju. Također su opisane i objašnjene modificirane inačice prijenosa metala u električnom luku, njihove mogućnosti i područja primjene te modificirani postupci MAG zavarivanja kojima su one temelj.

U eksperimentalnom dijelu rada, koji je izveden u Laboratoriju za zavarivanje, Fakulteta strojarstva i brodogradnje, Sveučilišta u Zagrebu, analizirana je mogućnost podešavanja parametara primjenom sinergijske upravljačke karakteristike na izvoru struje za MAG zavarivanje novije generacije. Također, analizirane su funkcije izvora struje za zavarivanje i kvantificiran njihov utjecaj na stabilnost prijenosa metala u električnom luku i geometriju zavara na osnovi snimljenih dinamičkih karakteristika.

Abstract (english)

In the theoretical part of this work MAG welding procedure, MAG welding parameters and conventional modes of metal transfer are briefly described. Special emphasis is placed on modern, inverter power sources, setup of parametars and their specific functions. Also modified modes of metal transfer are described, their possibilities and scope of application. Modified MAG welding procedures, which are based on modified modes of metal transfer, are also described.

In experimental part of this work, which was performed in Laboratory for welding, Faculty of mechanical engineering and naval architecture, University of Zagreb, possibilities of parameters setup on newer generation MAG welding power sources were analyzed. Also functions of welding power sources were analyzed and their impact on the stability of the metal transfer in arc and weld geometry was quantified through recorded dynamic characteristics.
