Corrosion characteristics on friction stir welding of dissimilar AA2014/AA6061 alloy for automobile application. 2019-28-0063

Friction Stir Welding (FSW) is a widely used solid state welding process in which its heats metal to below recrystallization temperature. FSW mostly avoids welding defects like hot cracking and porosity which are mainly in conventional welding techniques due to alloy’s higher heat dissipating nature and low re-crystallization temperature. In this process combining mechanical work and deformation heating to get high defect free welding joints. Aluminium Alloys 2014 and 6061 are generally used in a wide range of applications such as an automobile, shipbuilding and aerospace due to their high corrosion resistance, lightweight and good mechanical properties. In the present work, aluminium alloys of AA6061 and AA2014 were effectively welded by friction stir welding technique. The mechanical and Corrosion behaviour of the welded joints were investigated at different welding parameters.
