Mechanical of Behaviour of Dissimilar Material using Friction Welding

The friction welding is a Solid state welding process for different types joining of metals like ferrous metals and non ferrous metals. To join friction welding is the similar or dissimilar combination of materials with or without the filler rod. The friction welding produce heat generated at the interface of joining the specimen under plastic deformation by converting the rotational energy into heat energy by means of pressure. Friction welding used in the automotive, aircraft and aerospace industrial applications. The properties are austenitic stainless steel 304 and medium carbon steel AISI 1040. Both are with and without welded interlayer in different welding parameters. The materials selected in the nickel. The friction welding are conducted with the parameters such as forging pressure, rotational speed and friction time. The parameters are optimized three input parameters and three input level. Taguchi Orthogonal array is used for designing. Microstructure, tensile strength, micro hardness and FESEM-EDS are compared and analysed for weld with nickel interlayer and without interlayer of it.
