Friction Stir Welding of Al 5052 with Al 6061 Alloys

1/11/2008 · Friction Stir Welding (FSW) is a solid state welding technique in which a non-consumable rotating tool is used to make a joint between two components. The two components are oriented and clamped with appropriate fixtures. The rotating FSW tool is plunged into the components at the start point of the weld line and traversed along the weld line.

The application of a pinless tool in friction stir spot

Joining two dissimilar metals, specifically Mg and Al alloys, using conventional welding techniques is extraordinarily challenging. Even when these alloys are able to be joined, the weld is littered with defects such as cracks, cavities, and wormholes. The focus of this project was to use friction stir welding to create a defect-free joint between Al 2139 and Mg WE43.

Metallurgical and Corrosion Features of Friction Stir

This thesis focuses on the friction stir welding (FSW) between similar and dissimilar alloys. FSW is a solid state joining process that welds the work-pieces through a combination of heat generated by friction and mechanical stirring of the metals in the region of the joint. Being a solid state process, FSW can be used to weld alloys with significantly different melting points.
