Abstract

The paper presents a consistent set of results showing the ability of Laser Shock Processing (LSP) in modifying the overall properties of the Friction Stir Welded (FSW) joints made of AA 2024-T351. Based on laser beam intensities above 109 W/cm2 with pulse energies of several Joules and pulses durations of nanoseconds, LSP is able of inducing a compression residual stress field, improving the wear and fatigue resistance by slowing crack propagation and stress corrosion cracking, but also improving the overall behaviour of the structure. After the FSW and LSP procedures are briefly presented, the results of micro-hardness measurements and of transverse tensile tests, together with the corrosion resistance of the native joints vs. LSP treated are discussed. The ability of LSP to generate compressive residual stresses and to improve the behaviour of the FSW joints is underscored.
