Friction stud welding is a solid phase welding technique involving a stud, appurtenance or small pipe fitting being rotated at high speed while being forced against a substrate, generating heat by friction. The metal surfaces reach a temperature at which they flow plastically under pressure, surface impurities are expelled and a forged weld is formed.
