Rotary Friction Welding of Dissimilar Materials

open access: yesInternational Journal of Recent Technology and Engineering (IJRTE), 2019
Friction welding (FW) is a solid state welding method invented in 1940s by the welding institute. Without genuine liquefying of the materials, a normally excellent weld joint is produced with this procedure. The method is quick, environment friendly and easy to carry out.
