Abstract

Shape memory alloys are difficult to weld due to their own special properties, which lead to the problems of joints such as low strength, formation of intermetallic compounds, variations in phase transformation effects and its temperature, and changes of shape memory effect. However, different welding and joining processes are attempted to solve these problems. In this chapter, various welding processes such as tungsten inert gas welding, plasma welding, laser beam welding, electron beam welding, resistance welding, friction stir welding, friction welding, explosive welding, ultrasonic welding, diffusion bonding, adhesive bonding, brazing, and soldering are discussed on process capabilities and challenges to obtain shape memory welds.
