Results of experimental studies of nano-sized refractory compounds impact on structural and mechanical characteristics of a joint obtained by CO2 laser welding of metal plates are presented. Introduction of small quantity of specially prepared refractory nanoparticles with size less than 100 nm is shown to impact the alloy crystallization process, form fine-dispersed globular structure at its solidification. This results in increase of mechanical and operational properties of the weld seam
