| Abstract Scope |
Refill friction stir spot welding (RFSSW) is a solid-state spot joining technique that can be used to weld aluminum alloys in various thickness and alloy combinations. It is critical to identify the unique conditions that yield excellent bonded properties and the ability to repair a joint that was interrupted during the welding process. Qualified repair techniques are critical for successful implementation of a welding process for use on large weldments with a significant number of spot joints. The focus of this work is to demonstrate a repair technique for RFSSW that can be validated both numerically and experimentally. Modeling is performed in Transvalor’s Forge NxT 3.2 as a 2-D axisymmetric, thermo-mechanically coupled model, which has previously been validated for the RFSSW joining process. Repaired properties are shown to exceed 90% of the original mechanical properties of the RFSSW process. |
