Synopsis

There are several different types of welding processes, including friction stir welding (FWS), arc welding, and fusion welding. Here, we've used the FSW method to weld the aluminium alloys AA6061 and 5083 T6 together. This weld can be used in the aerospace industry to save weight, in ships to withstand corrosion, etc. In marines, 5083 T6 alloy is used inside for greater strength and AA6061 alloy is used outside for corrosion protection. Here, friction stir welding will be used to fuse these two aluminium alloys together. Due to the heat generated by friction, friction stir welding is a sort of welding procedure that joins two alloys, whether they are comparable or different. FSW is used to create super-strong, low-distortion welds. In this work, two different aluminium alloys, AA5083 and AA6061, were dissimilarly welded together at the butt joint using FSW. The fundamental idea behind FSW is the joining of two metal plates using a non-melting pin tool. Since aluminium alloys have a great strength to weight ratio compared to steel, there are many applications for them. In this study, we optimise the welding speed, the axial force, the rotating speed, the tilt angle, and the profiles of the tool pins. Utilising Minitab software, one can design the central composite, obtain the full factorial design analysis, and check the parameters and the welded section's strength and hardness.
