The study on structure and mechanical properties of surfaced coatings and welded joints of 09Mn2Si steel formed with the use of a standard electrode as well as one modified by adding titanium carbonitride nanoparticles was carried out. Optical and scanning electron microscopy, microhardness measurement were employed to investigate the structure at welding with a standard electrode, as well as to illustrate changes resulting from the electrode modification through adding titanium carbonitride nanoparticles. Evaluation of mechanical properties was performed by conducting tests on static, cyclic and impact loading. It is shown that welding with the use of the modified electrode gives rise to decreasing the size of ferrite grains and increasing impact toughness and fatigue life.
