This article describes the high-temperature solid-state welding process used to join members of similar or dissimilar materials by three stages, namely, primary bonding, bond-surface extension, and elimination of the original joining surface. It lists the various advantages and disadvantages of the high-temperature solid-state welding process. The article discusses important process parameters for high-temperature solid-state welding, such as temperature, pressure, welding time, and welding atmosphere. It concludes with information on the application of the process in the fields of aerospace and nuclear engineering.
