Abstract Scope |
Heat-treatable aluminum alloys, commonly used in aerospace and shipbuilding, are susceptible to weld zone failures and the formation of cracks in critical structural locations. Replacing large and expensive components can be time-consuming and costly. In-situ repair methods offer a promising alternative. Fusion-based welding and friction stir processing (FSP) have emerged as suitable techniques for repairing structures. This study investigates the feasibility of repairing cracks in a plate made of heat-treatable aluminum alloy 6061-T6 using a hybrid method combining conventional milling, metal inert gas welding (MIG), and FSP. An optimized heat treatment method was applied to enhance the properties of the repaired zone to match the base aluminum alloy. The influence of FSP and heat treatment was analyzed in detail, with insights into the mechanisms driving microstructure evolution and mechanical property enhancement. This hybrid repair method shows potential as a faster, more efficient alternative to component replacement in real-world applications. |
