Pressure welding technology is a solid state bonding process and generally involves heating the metal surfaces and then applying a suitable amount of axial pressure. In this state the metal components being joined undergo only microscopic deformation and the joining region is homogeneous and complete metallurgical bonding is possible without secondary materials or liquid phases. In the present work, pressure welding of titanium alloys has been investigated to fabricate several aerospace components with various complex configure. The result shows that the pressure welding method has been successfully applied with blow forming for near net shape forming of aerospace components, including high pressure tank for attitude control of spacecraft, and other lightweight structural panels.
