Sustainable Processing of Dissimilar Aluminium Alloy Joints by Friction Stir Welding

Analysis and Comparison of Friction Stir Welding and Laser Assisted Friction Stir Welding of Aluminum Alloy

Friction Stir Welding (FSW) is a solid-state joining process; i.e., no melting occurs. The welding process is promoted by the rotation and translation of an axis-symmetric non-consumable tool along the weld centerline. Thus, the FSW process is performed at much lower temperatures than conventional fusion welding, nevertheless it has some disadvantages. Laser Assisted Friction Stir Welding (LAFS...

Friction stir welding and processing

Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a de...

Effect of Friction Stir Welding on Mechanical Properties of Dissimilar Aluminium Alloys

Friction stir welding is advance joining process for different similar and dissimilar metals. It is commonly used for joining of Aluminium alloys. In this study an attempt were made to join commercial structuralaluminium with 7039 aluminium alloy. A zig-zag pattern of hardness was found in weld nugget. Microstructural characterization and fractography of joints were examined using optical and s...

Friction stir welding of dissimilar alloys – a perspective

Friction stir welding does not involve bulk melting of the components that are joined. This has inspired attempts to exploit it for joining materials which differ in properties, chemical composition or structure, and where fusion can lead to detrimental reactions. The purpose of this special issue of Science and Technology of Welding and Joining was to assess the status of friction stir welding...
