Abstract
<\/strong>The growing of high-strength low-alloy steels use in the welded metal structures manufacture is accompanied by an increase in the requirements for the reliability of prediction results in the “composition-structure-properties” system. The fractal analysis methods use makes it possible to establish a metal structure characteristics numerical parameterization, the metallographic analysis of which gave only a qualitative assessment. The article shows the fractal analysis possibilities for the numerical evaluation of such of the structure of weld metal characteristics as the total length of grain boundaries, the distribution of dislocations at the grains structural boundaries, the distribution density of non-metallic inclusions accumulations with a distance less than 5r from one another. There was show the possibility of the structure and non-metallic inclusions numerical parameterization in the “structure-fractal-properties” system for predicting the mechanical properties of the low-alloy high-strength steels weld metal<\/p>
