An aerospace system is made of metallic or nonmetallic materials. The main goal of this chapter is to obtain for designers, engineers, students, and researchers a big source of the newest information about the topics associated with the joining of different dissimilar materials in the aerospace industry, the newest progress as well as subsequent directions in addressing the topics. Scientists met the fact with the necessity of dissimilar welding of materials since they are looking for creative constructures or parts with outstanding properties. Sometimes a member needs a big temperature resistance in one zone and a good resistance to corrosion in another zone. Systems can need to wear resistance or toughness in one zone integrated with elevated tensile strength in another zone. Enhancing the potential of dissimilar welding with high properties is enabling new processes to light-mass aerospace systems. Most of the dissimilar welding research from 50 years ago has been related to metallic materials. There has been enhancing the research of dissimilar material joining including composites, ceramics, and polymers beginning from the 1980s. Enhanced application of these engineering materials is extending due to the special effecting needs for the resistance to corrosion, big ratio of strength to weight, resistance to erosion, strength at the elevated temperature, and producing light vehicles with decreased fuel consumption. The most important welding techniques used in aerospace systems involve liquid- and solid-state weldings such as GTAW, GMAW, flash welding, big energy density techniques like electron beam welding and laser welding as well as friction welding, diffusion welding, brazing, and ultrasonic welding.
