Because of the high heating and cooling velocity values, welding procedure is an unstable process. During
welding, changes in microstructure are occurring under overheating and/or cooling conditions. In comparing to the
parent steel (PM), throughout welding of steel alloys, a whole series of complex processes are performed which
influence to the appearance of different weldments microstructure and at the level of stresses in the weld metal
(WM) and the heat-affected zone (HAZ). In present paper, the analytic dependence between Vickers hardness (HV) values and cooling time im temperature interval from 800C to 500C (t8/5) will be determined using the test
results of experimental investigation of NIONICRAL 70 (NN-70) steel.
