Optimizing wrought AA2024, AA7075 and laser powder bed fusion printed AlSi10Mg similar and dissimilar refill friction stir spot welded joints

Description

Refill friction stir spot welding (RFSSW) is a solid-state spot joining method that has been successfully used for welding wrought aluminium alloys. Besides the wrought
aluminium alloys of 2000 and 7000 series, which are widely used In the aviation industry, additive-manufactured aluminium parts are on the rise to reduce the weight of
brackets and fixtures. In this research project, we investigate the RFSSW of AA2024-T3 and AA7075-T6 wrought aluminium joints and Laser Powder Bed Fusion (L-PBF)
printed AlSi10Mg similar and dissimilar joints. Finite Element simulations are established to better understand the welding process and to help find optimum process
parameters. Design of experiments approaches are used to find suitable process parameters with high static lap-shear strength. The results of our study can be used to
improve the quality of RFSSW joints and to develop new applications for the RFSSW technology.
