Mechanical Strength Of Dissimilar AA7075 and AA6061 Aluminum Alloys Using Friction Stir Welding

Mechanical Strength Of Dissimilar AA7075 and AA6061 Aluminum Alloys Using Friction Stir Welding

The present study focuses on the effects of material position and tool rotational speed on the tensile strength of dissimilar AA7071 and AA6061 welded aluminum alloys with a thickness of 2.0 mm in using a conventional milling machine. Ten joints were produced by varying tool rotational speeds and by...
