EXPERIMENTAL ANALYSIS OF FRICTION STIR WELDING ON DISSIMILAR AL AND BRASS ALLOYS

FSW process is an eco-friendly solid state joining technique compared to the conventional welding techniques. Research on friction stir welding between aluminium and brass has not yet been thoroughly researched; much of the work has been focused on welds characterizations and study of the material flow. There is however, a strong need in developing the industrial applications of FSW between aluminium and brass in the manufacturing sector for the enhancement of the industries. Thus, the use of the FSW technique to join aluminium and brass alloys and material shapes is of importance in the development of their industrial applications. In summary the Friction stir welding of two dissimilar metals ie., A6061 and Brass has been successfully conducted . The strength of the joint was observed less compared to base materials due to variation in melting points of aluminium and brass. The hardness of specimen welded with hexagonal tool profile was high compared to cone tool profile. Furthermore, new studies on FSW between aluminium and brass with respect to the process optimization and selection of cost effective FSW tools to produce sound welds still needs to be developed.
