In the present study, an attempt was made to examine the involvement of similar and dissimilar aluminum alloys when used with the A-GTAW process, to understand the relevant mechanisms behind the activity of flux , to understand the participation of similar and different aluminum alloys on A-GTA welding parameters and weld mechanical properties.A-GTAW for joining similar aluminum alloys gives lower mechanical properties i.e. tensile strength. The assembly of dissimilar aluminum alloys overcomes the disadvantage of GTA welding, which increases the mechanical properties, i.e. the tensile strength.The use of Activated GTAW assist process is one of the most important advances in overcoming the shortcomings of GTA welding, helping to increase the penetration depth and depth to width ratio of the weld pool, thereby increasing productivity. of welding and also helps to achieve better mechanical properties.
