  The using of nanotechnology in the welding process has great importance in developing the mechanical properties of welding joints for metals. This paper investigated the effect of addition TiO2 NPs to welding joints to improving the Impact toughness property of the welding joints. The cold spray coating method of the nanoparticles are used to adding the TiO2 NPs to the welding joints during the welding process. Three weight fraction are used for TiO2 NPs (0.75%, 1.5%, and 2%). The testing samples were prepared for Impact test, and microstructure by SEM. The results show the increasing in Impact toughness of welded joints with an increase of TiO2 NPs concentrations. The average Impact toughness for the welded sample without TiO2 NPs. was (162.4 J), while the average Impact toughness for the welded sample with (1.5)% T.. View more»
