The Mixing Condition and Mechanical Property of Friction Stir Welded Dissimilar Formed 3003 and 6061 Al Alloys

Article Preview

Abstract:

In the present study, AA3003, AA6061 were selected as the object to investigate the mixing condition and mechanical property of the dissimilar Friction Stir Butt Welding joint. Experimental results showed the two Al alloys of the joint were interwoven together in the river shape with an obvious gradient. When ω/v was moderate, the two kinds of materials can be better mixed together and improved the mechanical property. Meanwhile the bonding was complete under all the welding conditions. The joint coefficients could all achieve more than half of those of the base material and the best was 96% (ω=1541rad/min, v=142 mm/min).
