The algorithm for the weldability estimate was presented. In details were presented review of the mathematical relations that define the temperature – dependent space dimensioning in welds and influence of mechanical parameters. Later a brief outline of the metallurgical and micro-structural transformation was presented. Finally, the basic information on strains, stresses and normalised fracture mechanics parameters are characterised.
