Introduction

Welding processes are widely used in the fabrication of engineered structures. During the second half

of the twentieth century, fusion welding processes, wherein fusion is obtained by the melting of parent

material and usually a filler metal, dominated the welding of large structures. In 1991, friction stir

welding (FSW), which is carried out entirely in the solid phase (no melting), was invented.
