<jats:title>The Numerical Analysis of Weldability in the Design and Technological Processes Influence on the Exploitation Condition and Quality</jats:title><jats:p>Numerical weldability analysis is a new powerful research and development tool which is useful for metallurgists, technologist and design engineers. Saying strictly the numerical analysis of weldability comprises thermodynamic, thermomechanical and microstructural modelling of the welding process. The result of this analysis is material susceptibility (SU). The fracture resistance of welded joints is mainly characterised by normalised parameters:<jats:italic>K<jats:sub>Ith</jats:sub>/ K<jats:sub>IC</jats:sub>; δ / δ<jats:sub>c</jats:sub>, J / J<jats:sub>c</jats:sub>;</jats:italic>in the exploitation condition. From above-mentioned equations results that does not exist one global parameter which defines the step of susceptibility SU of base materials has been also executed with use of SINTAP program and Computational Welding Mechanics (CWM).</jats:p>
