Abstract

The Welding Institute (TWI) in Cambridge, England invented friction stir welding (FSW) late in 1991. TWI applied in December of that year for worldwide patent protection. The friction stir welding process is simple, energy-efficient and inexpensive relative to other welding methods. FSW can be implemented to make high quality welds with the most versatility – meaning the process can be used in almost all positions. Tensile, fatigue and bending tests have demonstrated that the properties of friction stir welded materials are superior to those made by other welding methods such as fusion or arc welding.
