Popis: The possibilities and the technological features of Gas Metal Arc Welding (GMAW) are considered in detail. The problems arising from the addition of nanosized particles in the liquid phase are analyzed from the point of view of the possibilities of the welding process. Possible methods of adding nanosized particles to the weld metal in GMAW are presented. Welded joints are obtained by active GMAW process, with nanosized particles added following specially developed methodology. The test specimens obtained from the welded joints are subjected to microhardness tests and metallographic tests. Conclusions are made about the influence of the nanoparticles on the properties of the modified metal.
