This volume discusses dissimilar metal joining by fusion and solid-state processes. It is a complex process due to differences in chemical compositions, physical properties, mechanical properties, and thermal properties of the parent metals to be joined. The contents focus on issues related to fusion and solid-state welding of dissimilar metals. The book is based on the fundamental and experimental investigation on methodologies used to overcome issues related to dissimilar metal joining by fusion welding (GTAW and its variant), resistance spot welding and solid state joining (friction stir welding, friction stir spot welding, and diffusion bonding) largely based on research investigation conducted at Indian Institute of Technology (IIT) Roorkee.
