Pre-weld friction stir processing mitigates hot cracking and strengthens AA6061 fusion welds

Abstract Hot cracking remains a significant challenge in the fusion welding of high-strength aluminum alloys, particularly AA6061, which is highly susceptible to solidification cracking in the fusion zone (FZ). This study investigates the efficacy of friction stir processing (FSP) as a pre-weld trea...
