Friction welding is widely used solid state welding method for joining of similar and dissimilar metals that uses rapid rotation of one component at high rpm and other component is brought in to contact at high forging pressure to get upset. Two pieces rotate in contact and heat necessary for welding is generated on friction plane. For this purpose a friction welding setup was designed. Vertical Milling Machine was used for friction welding. The materials used were Aluminium 6026 and Stainless Steel - 304. A Dial indicator was used to control the burn off length. Temperature torch was used to measure the temperature to simulate the results. Three parameters were varied Weld time, RPM & Burn off length at two different levels. Fixed parameters were length and diameter of the specimen. Total number of experiments conducted was eight. After friction welding macroscopic behavior (Tensile Strength, Temperature produced during friction welding & Composition change) & Microscopic behavior (Microstructure, Micro hardness, SEM) of the welded region was analyzed. The Microscopic and Macroscopic behavior with the friction welding parameters was studied in this work.
