| Abstract Scope |
Friction stir welding (FSW) is an advantageous joining process that is suitable for many engineering designs. The need for economical non-destructive evaluation (NDE) for welding is imperative for high volume industries. This need has led the development of many different inline force-based NDE methods. This work introduces the performance of a generalized NDE method that is applied to friction stir welds where the process parameters were not included in the NDE calibration. When this NDE method is applied to welds within calibration the process spatially detects defects with 94% accuracy with 4% false positives. In addition, the methodology proved 100% effective at positive detection when defects were present with zero scrap rate as a Go, No-Go test. |
