After welding, in the weld and in the heat-affected zone, residual stresses occur, which should be
removed by subsequent heat treatment in order to achieve good mechanical properties of the
welded joint. stresses in welds of 120 mm thick S235JR steel sheets. After annealing the weld in
a vacuum furnace, an average reduction in hardness in the weld by 8 - 12 HV was achieved. After
annealing, the residual stresses on the weld cross-section changed from -287 MPa to 224 MPa
compared to the stresses before annealing and became compressive throughout the weld crosssection.
