Abstract: Among all the non-ferrous materials, aluminium is widely employed in various aerospace, defence and industrial applications. The natural qualities, of aluminium and its alloys, like lightness, electrical and thermal conductivity, corrosion resistance, suitability for surface treatments, the diversity of the alloys and intermediates, ease of use, recycling make them usable in many applications. The applications demand the manufacturing of components by a superior manufacturing process, so that the products will be without any defects. Welding is one such process which is widely used in fabrication of aluminium components. Both fusion and solid- state welding processes are employed in the manufacturing of aluminium components. An attempt is made in this paper to take an overview of some fusion welding and some solid-state welding processes to weld Al and its alloys with a focus on the process parameters of these processes, tools used, micro structure of the welded specimens, thermal profiles, strength of joints and heat treatment. This is an attempt understand and summarize the issues related to welding of aluminium and its alloys.
