“…They found that the HAZ of the joint disappeared, and the strength and hardness were improved. Other studies also indicated that a forced cooling medium is beneficial for improving the mechanical performances of FSW aluminium alloy joints [20][21][22][23].…”

Friction stir welding (FSW) is a promising welding method for welding dissimilar materials without using welding flux. In the present work, 5A06-H112 and 6061-T651 aluminium alloys were successfully welded by friction stir welding with forced air cooling (FAC) and natural cooling (NC). Nanoindentation tests and microstructure characterisations revealed that forced air cooling, which can accelerate the cooling process and suppress the coarsening of grains and the dissolution of precipitate phases, contributes to strengthening and narrowing the weakest area of the joint. The tensile strength of joints with FAC were commonly improved by 10% compared to those with NC. Scanning electron microscopy (SEM) images of the fracture surface elucidated that FSW with FAC tended to increase the number and reduce the size of the dimples. These results demonstrated the advantages of FSW with FAC in welding heat-sensitive materials and provide fresh insight into welding industries.

“…As an innovative solid‐state process, friction stir welding (FSW) has been regarded as an ideal welding technique for joining these, often considered as “unweldable” aluminum alloys, due to eliminating the melting‐related problems of fusion welding, and thus improving the joint quality . This solid‐state joining process leads to minimal microstructural changes and higher mechanical properties than the conventional fusion‐based welding processes …”

“…[5] This solid-state joining process leads to minimal microstructural changes and higher mechanical properties than the conventional fusion-based welding processes. [6,7] It is well known that the FSWed joint is produced by rotating and plunging a FSW tool characterizing a specially designed cylindrical, shouldered tool with a small diameter pin into the joint line between two butted plates. [8,9] The microstructure of the FSWed joint, depending upon alloy composition, heat treatment conditions, and plastic deformation, plays a remarkable role in impacting mechanical properties of the joint.…”

A study of aluminum alloy 2024‐T3 friction stir welded (FSWed) joints under different rotation speeds at fixed travel speed of 200 mm/min is summarized. The effect of rotation speed on the hardness, tensile mechanical properties as well as corrosion sensitivity of the welded joints was explicitly investigated. The results show that the rotation speed has a remarkable influence on the shape and geometry of the stirred zone. Microstructure of the joint varied, while it was shown that microhardness was increased as the rotation speed of the process increased. This was attributed to the formation of high volume fraction of GPB zones under high rotation speed. An optimal in the strength to ductility compromise was obtained for the 600 rpm rotation speed. This was supported by the appropriate grain size and precipitates density and size, resulting in ultimate tensile strength of approximate 420 MPa and elongation at fracture of approximate 8.7%. This welded joint also exhibited the lowest corrosion susceptibility, while the heat‐affected zone proved to be more corrosion resistant than the respective friction stir zone.

AA6061 aluminum alloy has a gathered wide acceptance in the fabrication of light weight structures requiring high strength to weight ratio and good corrosion resistance. Friction stir welding (FSW) is an emerging solid state joining process in which the material that is being weld does not melt and recast. This process uses a non consumable tool to generate frictional heat in the abutting surfaces. The present investigation is aimed to study the tensile strength, microstructures and corrosion behavior of underwater friction stir welding (UFSW) welded joints of AA6061 at variable temperature of water and compare that result with normal friction stir welding process with same parameter. 4 mm thickness has been used as the base material for preparing single pass butt welded joints.
