The heat affected zone (HAZ) is the most susceptible region for corrosion occurrence in a welded joining. Besides microstructural variations, the corrosion susceptibility of HAZ is increased by stresses that act on it (residual ones, related to welding thermal cycles, added to external stresses) and also by stress concentration factors connected to the geometry of the weld edge (toe). Machining (grinding) of the weld edge is used to increase the smoothness (concordance) between the weld bead and the base metal. However, such techniques do not eliminate problems associated to the presence of inclusions, porosity and segregation, which increase corrosion wear. TIG Dressing technique has been used for reducing fatigue crack occurrence from str...
