 Dissimilar friction stir welding

Dissimilar friction stir welding (FSW) is a variant of traditional friction stir welding that involves joining two distinct materials, typically with different chemical compositions or physical properties, using a solid-state process. In standard friction stir welding, a rotating tool is used to generate frictional heat at the interface of two similar materials, which softens them and allows them to be forged together under pressure. In dissimilar FSW, the challenge lies in the different properties of the materials being joined.
