Abstract
Improving the strength properties of ferritic stainless steel welds is associated with reducing excessive grain growth. The article presents the research results on the effect of the titanium additive introduced to the weld material during the welding process of X2CrTiNb18 steel and using different temperature ranges of the heat treatment process for the welds obtained. Significant importance of the influence of titanium addition during welding and heat treatment operations on the change of weld morphology, including the reduction of ferrite grain growth and the change of selected mechanical properties of welds (strength, hardness, plasticity), was demonstrated.
