Zusammenfassung:Embodiments can include a self-reacting friction stir weld ("FSW") tool. The device can be configured to be portable and produce full penetration welds in situ. The FSW tool can include a system that cuts out a portion of the structure surrounding a defective portion of the structure. A work-piece can be inserted within the removed portion and friction stir welded to the structure via the FSW tool. A superior repair as compared to merely welding the defect can be achieved by replacing a portion of the structure surrounding the defect as opposed to merely welding the defect (e.g., the crack). A controlled geometric shaped weld beam can be generated for the interface between the work-piece and the structure, which may led to a stronger, more reliable weld.
