REDUCTION OF RESIDUAL STRESSES OF WELDED JOINTS OF MICROALLOYED STEEL ALLOYED BY NIOBIUM

During welding for relieving of residual stresses of welded joints of steel Niobal 43, approximately same or lower mechanical properties have been obtained than if annealing was not conducted. By annealing to the temperature of 650 0C the fracture effect cannot be improved without harmful acting to tensile strength.
