Short Review on Recent Advancement in Welding of Aluminium Based Alloys and Composites

Aluminium (Al) is one of the most widely used elements throughout the world. Alloys and composites of aluminium find huge application in various industries owing to their high strength-to-weight ratio, light weight, high thermal and electrical conductivity, corrosion resistance property. All these properties make aluminium and its alloys and composites to be used in various applications. Owing to its light weight, it is used in aviation and automobile sectors, where joining of parts play an integral role. Thus, welding of aluminium alloys and composites is an important factor during fabrication. Different welding processes are used for joining Al. Primarily, Friction Stir Welding (FSW) and Tungsten Inert Gas (TIG) welding are used. Also, Gas Metal Arc Welding (GMAW) process is often used. This paper makes a review study of different advancements in welding of Al based alloys and composite materials. Several findings related to mechanical properties, microstructure, macrostructure, microhardness etc. were reported.
