The purpose of this paper is to design a special fixture for measuring the forge pressure on the conventional lathemachine during rotary friction welding of mild steel specimens. The fixture consisting of hydraulic jack with pressuregauge mounting was attached on the tail stock of machine. The pressure gauge shows the forge pressure and frictionpressure applied. A fixture was designed to support the cantilever type section of the setup on tailstock and to stabilizethe stationary job .Friction welding is a solid state welding process that generates heat through mechanical frictionbetween a rotating/moving component and a stationary component. It is an important leap forward in manufacturingtechnology that will benefit a wide range of industries, including transportation electrical connections and aircraftindustry. The principal advantage of frictional welding, being a solid state process, are low distortion, absence of meltrelated defects and high joint strength, even in those alloys that are considered non-weldable by conventional weldingtechniques.
