Influence of Tool Shoulder Geometry on Properties of Friction Stir Welds in Thin Copper Sheets

Microstructure and mechanical properties of friction spot welds of dissimilar AA 5754

In the present study, friction spot welding or refill friction stir spot welding was performed to consolidate dissimilar AA5754 Al and AZ31 Mg alloys. The intermetallic compounds of Al12Mg17 and Al3Mg2 were primarily found in the weld, distributed at the interface between the base materials and in the Al top sheet. The distribution of the intermetallic compounds and the interfacial area between...

The Mechanical Properties Evaluation of the Welded Sheets of AA 3105 Aluminum Alloy Using Friction Stir Spot Welding (FSSW)

Friction stir spot welding (FSSW) is a type of solid state welding that is used in the connection of small pieces and light metals such as aluminum alloy especially. The technical problem during melting of aluminum alloys is one of the most important reasons for developing application of friction stir welding for aluminum alloys. In this research, the effects of important processing parameters ...
